EXECUTIVE SUMMARY
This report provides evidence on income distribution and poverty in 27 OECD countries over the
second half of the 1990s, using data that correct for many of the features that limit cross-country and inter-
temporal comparisons in this field. Patterns for income distribution and relative poverty in the second half
of the 1990s â a period of significant improvement in labour market conditions in most OECD countries
â conform to many of the longer-term trends identified in previous OECD analysis, but also highlight
some significant departures.
âą
Inequality in the distribution of household disposable income among the total population
increased slightly over the second half of the 1990s, continuing the trend of the previous decade.
âą
Relative poverty, measured with respect to a threshold set at half of median income, affected in
2000 around 11% of the OECD population, with an increase since the mid-1990s that is similar
to that of the previous decade. Absolute income poverty, which had declined by more than one-
third in the decade from the mid-1980s to the mid-1990s, fell by close to one-fourth in the five
years to 2000.
âą
Following steady increases in inequality in the distribution of market income among the
population of working age in previous decades, several OECD countries reversed or halted this
trend in the second half of the 1990s. Impacts on inequality in the distribution of disposable
income and relative poverty have so far been muted because of a reduction in the effectiveness of
public transfers and taxes in reaching those with greater needs.
âą
Relative poverty is, in most countries, most common among children than among the entire
population, and this increased further in the second half of the 1990s. While child poverty rates
are lower in countries with higher level of maternal employment, there is much diversity in
country experiences, suggesting that specific factors increase risks of destitution for children in
some OECD countries.
âą
Income of the elderly, relative to that of the rest of the population, stopped improving in the
second half of the 1990s. Their poverty rates, measured using a relative threshold, also increased
in several OECD countries, mainly reflecting changes in public transfers and taxes.

RESUME
Ce rapport examine la distribution des revenus et la pauvretĂ© dans 27 pays de lâOCDE pour la
deuxiĂšme moitiĂ© de la dĂ©cennie 90, sur la base de donnĂ©es corrigĂ©es dâune grande partie des paramĂštres
qui handicapent les comparaisons transnationales et intertemporelles dans ce domaine. LâĂ©volution de la
distribution des revenus et de la pauvretĂ© au cours de la deuxiĂšme moitiĂ© de la dĂ©cennie 90 â pĂ©riode
dâamĂ©lioration notable de la situation du marchĂ© du travail dans la plupart des pays de lâOCDE â sâinscrit
pour une grande part dans le prolongement des tendances à long terme qui se dégageaient des analyses
précédentes, mais présente aussi quelques écarts notables par rapport à celles-ci.
âą
LâinĂ©galitĂ© de la distribution du revenu disponible des mĂ©nages sur lâensemble de la population
sâest lĂ©gĂšrement accentuĂ©e dans la seconde moitiĂ© de la dĂ©cennie 90, prolongeant la tendance
observée au cours de la décennie précédente.
âą
La pauvreté relative, mesurée par rapport à un seuil fixé à la moitié du revenu médian, touchait
en 2000 environ 11 % de la population de lâOCDE, soit une Ă©lĂ©vation depuis le milieu des
années 90 analogue à celle observée dans la décennie précédente. Quant à la pauvreté absolue,
aprĂšs un recul de plus dâun tiers dans la dĂ©cennie prĂ©cĂ©dente, elle a baissĂ© de prĂšs dâun quart dans
les cinq années considérées.
âą
AprĂšs une pĂ©riode dâaccroissement constant au cours des dĂ©cennies prĂ©cĂ©dentes, lâinĂ©galitĂ© des
revenus marchands dans la population dâĂąge actif sâest rĂ©duite ou stabilisĂ©e dans plusieurs pays
dans la deuxiÚme moitié des années 90. Les incidences de ces changements de tendance sur
lâinĂ©galitĂ© dans la distribution du revenu disponible et sur la pauvretĂ© relative ont Ă©tĂ© attĂ©nuĂ©es
par la baisse dâefficacitĂ© des systĂšmes et dâimposition de transferts pour les catĂ©gories les plus
défavorisées.
âą
Dans la plupart des pays, la pauvreté relative est plus répandue chez les enfants que dans
lâensemble de la population, et ce phĂ©nomĂšne sâest encore accentuĂ© dans la deuxiĂšme moitiĂ© des
annĂ©es 90. Si les taux de pauvretĂ© des enfants sont plus faibles dans les pays oĂč le taux dâemploi
des mÚres est plus élevé, la situation est trÚs diverse selon les pays, ce qui donne à penser que les
risques de pauvretĂ© des enfants sont accrus dans certains pays de lâOCDE par des facteurs
spécifiques.
âą
Les revenus des personnes ĂągĂ©es, par rapport au reste de la population, ont cessĂ© de sâamĂ©liorer
au cours de la période. Leurs taux de pauvreté, mesurés par rapport à un seuil relatif, ont par
ailleurs augmentĂ© dans plusieurs pays de lâOCDE, principalement en raison des modifications
apportĂ©es aux systĂšmes et dâimposition de transferts.

INCOME DISTRIBUTION AND POVERTY IN OECD COUNTRIES
IN THE SECOND HALF OF THE 1990S
1. Introduction
1.
This paper extends to the end of the 1990s the analysis of income distribution and poverty
provided in Burniaux
et al
. (1998) and Förster and Pearson (2002).
1
It illustrates some of the findings from
a third wave of country submissions based on national household surveys and other micro datasets. These
submissions are based on a standard questionnaire, which uses common assumptions and definitions to
increase the degree of cross-country comparability (Annex 1). The data are based on the concept of
equivalised disposable income of individuals (
i.e.
the disposable income of households, adjusted for
household size) broken down by gross income components (
i.e.
before payment of direct taxes and social
security contributions levied on individuals) and presented for a variety of socio-demographic
characteristics of individuals and households. Efforts have been made to maximise the country coverage of
the data â available for 27 OECD countries â so as to allow the identification of common trends.
2.
The use of a common methodology and definitions allows us to overcome many of the
comparability issues that limit cross-country and inter-temporal comparisons of income distribution and
poverty among OECD countries. The data used in this paper, however, are not without limits. First, priority
has been given to maximise country coverage rather than to collect continuous time series for each
individual country. Second, while common definitions are used, the underlying data differ in some respects
that escape standardisation: they are based on household surveys in most cases, but rely on a combination
of survey and administrative data for a few countries (Belgium, Denmark, Sweden); further, even when
household surveys are used, data for different countries are affected by differences in survey design,
response rates and imputation methods used to integrate the survey data.
2
Third, the extent to which
income and population data from household surveys match independent estimates (
e.g.
from national
accounts) may differ across countries and over time, possibly distorting comparisons. Finally, the period
covered ends around the year 2000 â a cyclical peak in most OECD countries.
3.
Beyond these methodological aspects, other limits relate to the significance
for policy
of the
comparisons undertaken in this paper. In this respect, two issues are important. First, the focus in this paper
is on income distribution among individuals and households
at a point in time
: in other words, the data
used do not allow us to distinguish between persistent and temporary conditions,
or to track how conditions
1
While, for most countries, the data in this paper extend the series used in previous OECD publications,
revised estimates are presented for Denmark, Germany, Hungary, Japan (based on a different survey),
Mexico and the United States (based on the internal version of March
Current Population Survey)
. In
addition, this report presents for the first time data for the Czech Republic, reunified Germany,
Luxembourg, New Zealand, Poland, Portugal, Spain and Switzerland. No updates were available, at the
time of writing, for Belgium and Spain. Updates refer to the year 2000 for most countries but to 1998/99
for Australia; 1999 for Austria and Greece; 2001 for Germany, Luxembourg, New Zealand and
Switzerland; and 2002 for the Czech Republic, Mexico and Turkey.

Although "weighting" of responses is used to provide a more representative picture of the population in
each country, this does not eliminate biases that can accompany low response rates.

change over the different stages of each individualâs life-course. Second, this paper presents evidence on
the impact of taxes and public transfers on income inequality and poverty irrespective of the goals of
policies. In practice, the policies that most affect income distribution and poverty at a point in time pursue
a variety of objectives â providing social insurance against various contingencies, improving economic
efficiency, mobilising additional labour resources â rather than redistributing income
per se.
In these
cases, the crucial issue is to design policies that achieve multiple goals simultaneously, and to shift trade-
offs when such goals conflict with each other.
4.
The paper is organised as follows. The first section identifies some of the stylised facts that
characterise the experience of OECD countries over the second half of the 1990s in terms of income
inequality and poverty among the entire population, comparing these with longer-term trends described in
previous OECD studies. The second section looks at the experience of the population of working-age, with
a special focus on the role of labour markets, taxes and welfare systems. The third section looks at the
experience of children and of households with children. The last section considers the elderly population,
and how changes in pension systems have affected their well-being and poverty risks.
2.
Trends in inequality and poverty for the entire population in the second half of the 1990s
5.
This section, which looks at data for the
entire
population, highlights both cross-country
differences in the
levels
of the various inequality and poverty indicators, and ways in which
changes
over
the second half of the 1990s differ from the long-term trends identified in previous OECD analysis. One
problem, for analysis of changes over time, is that inequality and poverty indicators for individual
countries refer to specific years that may differ in terms of the cyclical position of each country. In theory,
changes between these years may not be fully representative of underlying trends. In practice, however, a
comparison with "commonly used" measures of income inequality for several OECD countries suggests
that this consideration is of limited importance for most countries.
3
2.1.
Levels of income inequality
6.
Our starting point for assessing distributive patterns prevailing at the end of the XXI
th
century in
OECD countries is represented by levels of inequality in the distribution of equivalised disposable income.
Figure 1 displays one widely used summary indicator of income inequality â the Gini coefficient of income
concentration
4
â in 27 OECD countries in the latest year available. Four groups of countries can be
distinguished in terms of increasing levels of inequality:
âą
The four Nordic countries (Denmark, Sweden, Finland and Norway), together with Austria, the
Czech Republic, Luxembourg and the Netherlands, all display Gini coefficients at around 26 (at
least 15% less than the OECD average value).
3
Annual time-series of "commonly used" measures of income inequality in nine OECD countries â shown
in Atkinson (2002) â display relatively minor variations around the trend (with the exception of Italy),
suggesting that the years used in this paper are quite representative of the values prevailing over the period
considered.
4
The Gini coefficient is defined as the area between the Lorenz curve (which plots cumulative shares of the
population, from the poorest to the richer, against the cumulative share of income that they receive) and the
45
o
line, taken as a ratio of the whole triangle. The values of the Gini coefficient range between 0 in the
case of âperfect equalityâ (each share of the population gets the same share of income) and 100 in the case
of âperfect inequalityâ (all income goes to the share of the population with the highest income).
DELSA/ELSA/WD/SEM(2005)1
10
âą
Other Continental European countries, together with Hungary, Canada, Spain, Ireland and
Australia show higher values of the Gini coefficient than those in the first group â between 27
and 30.5 â but still below the average value for the OECD as a whole.
âą
New Zealand, the United Kingdom and the United States, as well as Greece, Portugal, Italy
5
,
Japan and Poland, record values of the Gini coefficient between 31 and 36 â above the OECD
average.
âą
Mexico and Turkey, with values of their Gini coefficients of around 45, are clear outliers in this
league table â the difference between their Gini coefficient and that of Poland (the third highest
country) is close to the difference between Polandâs and that of lower inequality countries.
A simple OECD average of the Gini coefficient is 30.6 (29.4 when Mexico and Turkey are excluded).

The income concept used is that of disposable household income, adjusted for household size (e=0.5). Gini
coefficients multiplied by 100. "Most recent year" refers to the year 2000 in all countries except 1999 for Australia,
Austria and Greece; 2001 for Germany, Luxembourg, New Zealand and Switzerland; and 2002 for the Czech Republic,
Mexico and Turkey; In the case of Belgium and Spain (countries shaded in the figure), the data refer to 1995.

7.
The Gini coefficient is just one measure of income concentration. Analysis of three additional
income inequality indicators â the squared coefficient of variation (SCV), the mean-log deviation (MLD)
and the inter-decile ratios
6
(Annex Table 3) â suggests, however, that the four broad country groups
5
In the case of Italy, income from financial assets is excluded from disposable income to ensure
comparability with results from previous years. Its inclusion raises the Gini coefficient by around 7% (from
33.4, shown in Figure 1, to 35.7).
6
The P90/P10 inter-decile ratio is the ratio of the lower bound value of the top income decile to that of the
first. The squared coefficient of variation is the variance of average income of each decile, divided by the
square of the average income of the entire population. The mean log deviation is the average value of the
natural logarithm of the ratio of mean income to the income of each decile. All these summary indicators
have different upper and lower bounds: the squared coefficient of variation has a lower bound of 0 and
upper bound of infinity, while the mean log deviation and inter-decile ratio have a lower value of 1 and no
upper bound. Also, each index differs in its sensitivity to changes at various points in the distribution.
Relative to other indices, the Gini coefficient is less sensitive to changes at the two extremes of the
distribution, while the Mean Log Deviation is more sensitive to changes at the bottom of the distribution,
and the Squared Coefficient of Variation is more sensitive to changes at the top.
DELSA/ELSA/WD/SEM(2005)1
11
identified above are robust to the choice of the summary indicator.
7
In general, Nordic countries together
with the Czech Republic and Luxembourg consistently display lower levels of income inequality. Also
included in the lower-inequality group, according to the indicator used, are some other Western European
countries (Austria and the Netherlands in the case of MLD; and Austria, France, Germany and Netherlands
in the case of SCV). Hungary, other Western European countries and Japan tend to cluster around the
middle of the ranking for all the indicators used, while Switzerland records below-average values for the
Gini coefficient, decile ratio and MLD but scores somewhat higher on the SCV index (indicating greater
concentration at the very top and greater equality across other parts of the income distribution). Higher
inequality levels are consistently recorded by some Anglo-Saxon countries (especially New Zealand, the
United Kingdom and the United States) and Southern European countries, while Turkey and Mexico
record the highest inequality whatever the indicator used.
8.
Country differences in these various inequality indicators, however, do not match closely
measures of individuals'
perceptions
of whether income inequality is "too high" in the country where they
live. Figure 2 plots data on the share of individuals that agree with the statement that income inequality is
too large, based on surveys undertaken in 1999 under the
aegis
of the International Social Science
Programme, and values of the Gini coefficient of income inequality discussed above. While in all OECD
countries a majority of respondents agreed with the view that income differences were "too large" at the
end of the 1990s, there are large differences across countries, from around 60% in the United States to 90%
or more in Hungary, Italy and Portugal. The share of respondents perceiving income inequality as too large
is lowest in the United States â where the Gini coefficient is above the OECD average â and highest in
Portugal, where the Gini coefficient is also high. A weak association between real and perceived
inequalities also holds when using other inequality indicators. This suggests that, beyond actual inequality,
other factors play a significant role in shaping these perceptions.
8
Perceptions about income inequalities,
however, critically shape attitudes towards government policies aimed to reduce them (Figure 3).

Note:
Perceived inequalities in 1998 (shown as bars on the left-hand axis) are measured by the share of respondents who agree or
strongly agree with the statement "differences in income are too large"; data for Italy refer to 1992. Actual inequalities are measured
by the Gini coefficient of inequality in 2000 (1995 in the case of Italy) (shown as diamonds on the right-hand axis).

Data collected in previous waves also suggest that the grouping of countries in terms of levels of income
inequality is relatively unaffected by different choices about scale economies in consumption.

Surhcke (2001), who analyses a range of determinants of perceptions towards income inequality, reports
greater "tolerance" towards inequality among individuals with higher income, those who experienced
upwards income mobility over the past ten years, those who believe that people get rewarded for effort,
intelligence and skills, as well as among men, youths, and those living in smaller families. In his results,
tolerance towards inequality is lower in countries with higher income inequality, and in those that
underwent a transition from socialist regimes.

Trends in income distribution
9.
Table 1 summarises trends in the distribution of equivalised disposable income over three
different time periods, based on movements in the value of the Gini coefficient. While, in general, the
statistical significance of a given change in the Gini coefficient depends on the sample size and the design
of different surveys, conventional benchmark are used in Table 1: changes in Gini coefficients between
zero and 2% are characterised as "no change"; changes between 2% and 7% as "small"; changes in excess
of 7% as âmoderate"; and changes in excess of 12% as âstrong". Countries are attributed to different
columns of Table 1 according to the size of changes in the Gini coefficient over different time periods.
9
Main patterns, based on this conventional classification, are as follow:
âą
No common trend in income inequality is evident over the period from
the mid-1970s to mid-
1980s
. Across the seven countries for which information is available, the Gini coefficient of
income inequality increased in three, and narrowed in four. A simple average across the seven
OECD countries shows a decline of 3.2% in the Gini coefficient of inequality â despite some
pronounced movements in the various countries.
âą
There is stronger evidence of a common trend across OECD countries in the period from
the mid-
1980s to the mid-1990s
. Over this decade, the Gini coefficient decreased in three of the
25 countries (only slightly in two of them), remained stable in five, and increased in the
remaining 17 (by significant amounts in most of them).
10
A simple average across the countries
9
Because of its shorter length, however, a smaller cumulative percentage change of the Gini coefficient in
the most recent period does not necessarily imply a deceleration in underlying trends.
10
Part of the significant increase in inequality in Norway may be explained by a major tax reform
implemented in 1992. This reform expanded the tax base and, as a result, some formerly âinvisibleâ capital
income was identified in the data.
DELSA/ELSA/WD/SEM(2005)1
13
for which data are available over this period shows an increase of around 6% in the Gini
coefficient of income inequality.
âą
No common trend in income inequality is apparent over the most recent period,
from the mid-
1990s to 2000
. The Gini coefficient declined in five of the 24 countries for which information is
available, was stable in 10, and increased in the other 9 (in most cases by small amounts).
11,12
A
simple average across the 20 countries for which data are available since the mid-1980s shows a
small rise in the Gini coefficient of income inequality in the second half of the 1990s (1%), as
compared to stronger increases in the previous decade.
13
As the largest increases in the Gini
coefficient occurred in countries characterised by low inequality, dispersion in inequality across
countries narrowed in this period, in contrast to trends over previous decades.
14
11
In the case of Mexico, however, national data based on the same household survey used in this paper point
to an increase in inequality in the period from 1996 to 2000, followed by declines from 2000 to 2002.
12
For the United Kingdom, the data on income distribution and poverty used in this note (based on the
Family Expenditure Survey)
differ from those commonly used in most national discussions (based on the
Family Resource Survey).
While the latter survey has a sample size three times larger than the former,
results are available for a shorter period. Recent trends based on the
Family Resource Survey,
as
summarised by Brewer
et al.
(2004), point to a significant increase in the Gini coefficient of income
inequality from 1996/97 to 2000/01, followed by small reductions in the two following years.
13
These "average" changes in inequality over the two periods are influenced by opposite movements in
Mexico and Turkey, which recorded an increase in inequality from the mid-1980s to mid-1990s and strong
declines between the mid-1990s and 2000. When excluding those two countries, the average Gini
coefficient increased by 5% over the first period and by 2% over the past five years.
14
The standard deviation of the Gini coefficient declined by around one fifth over the most recent period,
after having increased by a similar amount in the period from the mid-1980s to the mid-1990s.

Different measures of inequality can give different indications about changes in inequality.
Annex Table 3 shows Gini coefficients alongside the three other summary indicators of income inequality
previously used: the income ratio between the top and bottom decile (P90/P10 ratio), the mean log
deviation of equivalised disposable income, and the squared coefficient of variation. On average, two of
the four indicators point to declines in inequality in the second half of the 1990s, following increases in the
preceding decades; and to moderate increases when excluding Mexico and Turkey. With respect to the
most recent period, all indices point to increases in income inequality in nine countries: Canada, Czech
Republic, Denmark, Finland, Greece, Japan, New Zealand (where only two indicators are available),
Sweden and the United Kingdom; and to declines in seven countries: France, Germany (old and new
LĂ€nder together), Italy, Mexico, Poland, Portugal and Turkey (only two indicators available). For the
remaining eight countries (and the old LĂ€nder of Germany), the various inequality indices move in
different directions. Over the previous decade, indicators suggested an unambiguous increase in inequality
in 13 countries (values in bold in Annex Table A.3), an unambiguous decrease in two (values in italics),
and movements in different directions in 9.
11.
Differences in the direction of changes in inequality provided by the different indicators partly
reflect the different weight that each indicator gives to different portions of the distribution. It is therefore
important to look closer at changes at different point of the distribution. When, for instance, persons in the
middle of the distribution lose ground relative to those at the bottom and top, a âhollowing outâ of the
distribution occurs. Conversely, a widening of the distribution could reflect those at the bottom becoming
poorer, those at the top improving their situation, or a combination of the two.
DELSA/ELSA/WD/SEM(2005)1

12.
Previous OECD analyses have noted that, in the period from the mid-1980s to mid-1990s,
changes in income distribution were dominated by movements at the higher end of the spectrum: in 16 out
of 22 OECD countries persons in the top quintile increased their share of disposable income, while in eight
countries those in the bottom quintile lost ground (moderately) relative to the average (Förster and Pearson,
2002). Developments in the most recent period (Table 2) are less clear-cut: persons in the bottom quintile
lost ground slightly in seven countries, and gained slightly in two (Mexico and Turkey); those in the top
quintile increased their share of household disposable income in eleven countries (substantially so in
Finland and Sweden), while losing considerable ground in four. On the other hand, middle-income groups
gained significantly at the expense of both lower and higher incomes groups in Ireland, and of higher
incomes groups in Mexico, Poland and Turkey. In a majority of countries, and on average, income shares
in the bottom, middle and top quintiles were broadly unchanged from the mid-1990s to 2000. Assessments
of changes in the distribution at the top of the scale, however, critically depend on how accurate are survey
measures of high income and on confidentiality limits applied by statistical agencies (Box 1).

Box 1. Survey measures of high income
How good are the data used in this report at measuring high incomes? The short answer is "probably not
veryâ, although this varies among countries. Quality of data on high incomes depends on how broad is the income
concept used, and on confidentiality norms applicable to persons with very high income. With regard to the first issue,
the main feature is whether the income concept encompasses income sources that disproportionately accrue to the
very rich. Capital gains are generally excluded from the income surveys of most OECD countries. Similarly, changes in
the remuneration package of managers (e.g. the growing importance of stock options) have increased the importance
of flows that are likely to be poorly or not recorded in household surveys. With regard to the second issue, the main
feature is whether survey data âtop codeâ income or earnings beyond a given threshold. Use of âtop-codedâ values will
underestimate the extent of inequality at a point in time, while an increase in the share of the population that is âtop
codedâ will dampen the recorded rise in income inequality.
While problems in the measurement of high income due to the exclusion of income streams that are most
important for individuals at the top of the scale are common to most countries, âtop codingâ is a specific feature of the
data for Japan and the United States. In the case of Japan, the data used here exclude persons with income three
times above the standard deviation (1.6% of the total population in 1995 and 1.3% in 2001). In the case of the United
States, most analysis of income distribution â including the one presented in Burniaux
et al.
(1998) and Förster and
Pearson (2002) â rely on the "public use" version of the March supplement to the
Current Population Survey.
These
data are however affected by confidentiality limits imposed upon different income sources and by changes over time in
the methodology used by the Census Bureau with respect to top-coding. While analysts (including previous OECD
work) have applied various adjustments to the public-use data to improve temporal consistency, these adjustments are
only proximate. To remedy for his weakness, the US data used in this paper are based on the Census Bureau "internal
use" version of the March CPS.*
Information about the importance of the narrow income concept used in household surveys for measuring
high income in the United States is available from studies by the US Congressional Budget Office (CBO), which
combines the Census data used in this paper with tax records to track income trends near the top of the distribution.**
The CBO data show large real income gains for the top quarter and top 1% of the US population during the 1980s, and
real losses for individuals in the bottom 50% of the population; over the 1990s, although real income gains are spread
more widely than in the previous decade, income gains at the very top continued to exceed those at the bottom. Tax-
based data for 4 OECD countries on the share of the equivalised disposable income accruing to the top 1% of the
population (as a share of the income of the top decile), as presented in Atkinson
(2002) and reproduced below,
suggest large increases in this share in all countries except France.

-----------
*
The US data used in this paper remain affected, however, by changes in the maximum values recorded in the survey questionnaire
(in 1979, 1985 and 1993) and by processing limits imposed by the Census Bureau to minimize the impacts of recording errors and
prevent volatility of annual statistics. According to Welniak (2003), changes in recording limits had no effect on the Gini coefficient of
(non-equivalised) household (pre-tax) income in 1979 and 1984, while increasing it by 2% in 1993.
** CBO also adds to the Census income data in-kind and non-cash-income (such as income from food stamps, housing assistance
and health insurance coverage), tax-financed wage supplements (such as Earned Income Tax Credits) and deduct payments for
income and payroll taxes. The CBO income concept refers to individuals and is adjusted for economies of scale in consumption.

Changes in income shares of different quintiles, as shown in Table 2, do not reflect the real
income
changes
experienced by persons at different points of the income ladder. These absolute changes
are a function of both trends in income inequality (how persons at different points of the income ladder
fare relative to others) and of the overall pace of growth of household disposable income. Table 3 shows
information on the annual rate of growth in equivalised disposable income in real terms (i.e. deflated by the
increase in the consumer price index), based on the household surveys used in this paper, for people at
different points in the income distribution over the decade since the mid-1980s and the 5-year period since
the mid-1990s. Two main features emerge:
âą
First, most OECD countries experienced a higher real income growth in the second half of the
1990s, relative to the previous decade, when data are averaged across all individuals: the only
exceptions are Japan, Mexico and Turkey â where equivalised disposable income declined in
real terms since 1995 â and the Netherlands and the United States â where gains are lower than
in the previous period.
15
In all other countries, the faster pace of real growth in equivalised
disposable income on average
implied that persons at all income levels experienced stronger
gains than in the previous period.
âą
Second, differences in the pace of income growth across the distribution are often significant. At
the lower end of the income distribution, for example, the decline in
average
real household
income recorded in Japan in the period 1995-2000 seems to have mainly affected persons in the
bottom two deciles. Persons in the top two deciles recorded larger gains than those at the bottom
in most OECD countries in the second half of the 1990s, but the differences are smaller than
those recorded in the previous decade.
14.
It should be stressed, however, that the patterns highlighted by Table 3 are shaped by the specific
features of the data and definitions used. First, the income concept used in household surveys differs in
important respect from that embodied in the national-accounts measures conventionally used in analysis of
living standards, and changes in the "coverage" of the survey data can distort trends over time.
16
Second,
changes in equivalised disposable income are affected by both the overall trends in household income and
by changes in household size across different income deciles.
17
15
In the case of the United States, national accounts data show stronger gains in real per capita household
income in the second half of the 1990s relative to the previous decade.
16
Analysis by Siminski
et al
(2003) suggests that the Australian data based on the
Household Expenditure
Survey
used in this report are characterised by relatively low population estimates until the mid-1990s, and
by estimates of gross income in 1975-76 that are well above those in later years; survey data for 1975-76
also produce relatively high estimates of per capita wages and salary income (as well as own-business
income and income tax) and low estimates of per capita income from government transfers. Both effects
skew the
income distribution away from the bottom end and dampen growth in income relative to later
periods. Because of these considerations, Australian data from the
Household Expenditure Survey
of
1975/76, as presented in the previous OECD reports, have been omitted from the present analysis.
17
Because of declines in average household size recorded by most OECD countries over this period, the
gains in equivalised income shown in Table 3 are lower than those for per capita income.

2.3.
Levels and trends in income poverty
15.
Changes in income distribution are of greater concern when they affect those at the bottom of the
income scale. Over the second half of the 1990s, the greater attention paid to poverty in many OECD
countries
18
has been accompanied by changes in the way poverty is conceptualised,
i.e.
as a multi-
dimensional phenomenon that stretches beyond income to include inadequate access to learning, housing,
poor health, and recourse to debt to meet ordinary living expenses. Consumption-based measures of
poverty, based on peoplesâ access to various essential goods and services, have been used in national and
18
At the World Summit on Social Development, held in 1995, governments agreed to the commitment of
eradicating absolute poverty by a target date set by each country. At the regional level, the European
Council agreed in December 2000 that the âfight against poverty and exclusionâ should be pursued through
the definition of commonly-agreed objectives for the European Union, the development of national action
plans to meet these objectives, and the periodic reporting of progress through statistical indicators" (the 20
so-called âLaeken indicatorsâ). At the national level, some countries have adopted explicit targets to reduce
or eradicate poverty, either for the whole population (e.g. Ireland, in the context of its [2000] âNational
Anti-Poverty Strategyâ) or for selected sub-groups (e.g. the United Kingdom). Poverty goals have also
often been set through ânational sustainable development strategiesâ adopted by many countries in the
wake of the 2002 World Summit on Sustainable Development.
DELSA/ELSA/WD/SEM(2005)1
19
regional contexts (Box 2) while subjective measures of poverty are explored in others.
19
While these
alternative measures are important for in-depth poverty assessment
20
, low income remains the dimension
that is more suited for cross-country and times-series comparisons aimed at identifying common trends. At
the same time, however, poor reporting of means-tested benefits and other survey features may also imply
that data quality is low, in some countries, for those at the lower end of the income distribution.
Box 2. Assessing poverty: consumption, assets and income measures
The case for assessing poverty and inequality on the basis of
consumption
rather than current income is
strong. As consumption streams are more closely related to long-term income, they avoid counting as poor many
families that, when suffering temporary income falls, are able to maintain a constant standard of living by lower savings
or higher borrowing. Studies that have relied on consumption data typically report lower rates of poverty and inequality,
relative to income-based estimates. Evidence, limited to the United States, suggests that greater income inequality
among individuals from 1972 to 1998 has not been matched by higher inequality in consumption (Krueger and Perri,
2002), as higher borrowing and lower asset holding allow to smooth income variations. Estimates for the United States
also show that around one quarter of all households had asset holdings in 1999 insufficient to meet basic needs for
more than three months (based on the
Panel Study of Income Dynamics
), with this share increasing to 40% when
home equity is excluded (Caner and Wolff, 2004).
Data on consumption and ownership of different goods have been used to develop direct indicators of
material well-being, measured in terms of ownership of appliances and electronic goods, housing and neighbourhood
conditions, access to community services, and ability to meet basic needs (Census Bureau, 2003). Questions
designed to asses the success of families in making ends meet are included in the
European Community Household
Panel Survey
and in the US
Survey of Income and Program Participation.
In practice, however, the difficulties in
deriving quality data on consumption and assets remain daunting, in particular in an international context. These
difficulties relate to both the treatment of durable goods and work-related expenditures, as well as to how to aggregate
measures of deprivation in specific areas (e.g. housing, heating) into a single index. More generally, consumption-
based measures of poverty may be criticised on the ground that they relate to actual behaviour,
as shaped by
individuals' preferences, rather than to the resources
constraining their decisions.
16.
Even when limiting assessments of poverty to low income, differences in country practices are
substantial. These differences are reflected in the poverty thresholds used to identify the poor. While some
countries rely on an
absolute
threshold â typically the cost of a minimum basket of goods and services
deemed to be required to assure minimum living standards, indexed over time
21
â others use measures of
19
For example, surveys for EU countries, based on questions about the extent to which the disposable
(weekly) income of respondents falls below what they deem necessary to make ends meet, show
âsubjectiveâ levels of poverty distinctly greater than those based on âobjectiveâ measure (based on a 60%
disposable income threshold) but also little changes in country rankings (Gallie and Paugman, 2002).
Förster
et al.
(2003) compare subjective poverty, income poverty and multiple deprivation measures across
18 countries of the enlarged EU: their results suggest that differences between âoldâ and ânewâ EU
member states are less pronounced for subjective poverty than for deprivation and income poverty.
20
Alternative measures of poverty typically display little overlap with income-based measures. Data from the
1999 âSurvey on Poverty and Social Exclusion in Britainâ, reviewed by Bradshaw and Finch (2003), show
that despite the similar level of poverty on three different definitions â "income poverty", i.e. equivalent
disposable income before housing costs less than 60% of the median (19%); "subjective poverty", i.e.
respondents declaring that their household income is âa littleâ or âa lotâ lower than the income they regard
as required to keep households out of poverty (20%); and "deprivation"
,
i.e. the proportion of households
who cannot afford four or more (survey-based) âperceived necessitiesâ (17%) â only 16% of all
respondents are poor on at least two dimensions, and less than 6% are poor on all three of them.
21
For example, the official poverty line in the United States is defined as the costs of an adequate diet,
multiplied times three (i.e. based on the assumption that food represents around
â
of household
expenditure), adjusted annually for inflation. For a family of four, this poverty line was about half of the
median disposable income of families of that type in the early 1960s, while it is now a little over one
quarter. Mexico introduced in 2001 three poverty lines based on absolute thresholds (food poverty, poverty
of capabilities and asset poverty), each of which is representative of different levels of unsatisfied needs.
DELSA/ELSA/WD/SEM(2005)1
20
the
relative
income of different groups. The use of either absolute or relative thresholds for measuring
income poverty has important implications for policy,
inter alia
for assessing the role of economic growth
in reducing poverty.
22
However, both absolute and relative income poverty provide important information
to policy makers, and they are ultimately complementary. Moreover, while in theory these two approaches
to the measurement of income poverty represent poles of a continuum of combinations, in practice the
greater the commitment of governments to reducing poverty in all its dimensions, the lesser the conflict
between them becomes.
17. Use
of
absolute
thresholds poses difficult methodological issues in the context of cross-country
comparisons (Förster 1994). One way to illustrate how the extent of âabsoluteâ poverty has changed over
time is to use a relative income threshold in a base year for each country and to keep it unchanged in real
terms
23
. On this measure, all OECD countries have achieved significant reductions in absolute poverty
since the mid-1980s (Figure 4). By 1995, absolute poverty was only one-sixth of the level it had reached
ten years earlier in Ireland and Spain â countries that have undergone radical economic transformations
â and close to 70% lower in Sweden. The decline has continued in the second half of the 1990s, with the
Czech Republic, Germany and Japan as the sole exceptions. On average, across 15 OECD countries for
which this information is available, absolute poverty rates have declined by more than one-third in the
period from the mid-1980s to the mid-1990s, and by close to one-fourth in the (shorter) period from the
mid-1990s to 2000.

Note:
Levels of absolute poverty rates in the mid-1990s are set equal to 1. Absolute poverty, as here defined, refer to
thresholds set at 50% of median equivalised disposable income in the "base year", kept constant in real terms in the
following years. The "base year" differs across countries (mid-1980s for most countries, except the Czech Republic,
Hungary and Poland â where it refers to the mid-1990s â and Australia and the United States â where it refers to
the mid-1970s). The OECD average value is the unweighted average of 15 OECD countries for which information is
available both in the mid-1980s and in 2000. Exact years are those specified in the note to Table 1.

22
When poverty is defined with reference to an absolute threshold, higher economic activity (i.e. a shift to
the right in the distribution of household income) will reduce poverty, although by decreasing amounts. As
an illustrative example, Freeman (2001) calculates that â when income is assumed to be normally
distributed â a 0.1 point increase of mean income (relative to its standard deviation) would reduce
absolute poverty by 3.2 points when 30% of the population is in the bottom tail of the distribution, by 2.6
points when 20% of the population is in the bottom tail, and by 1.6 points when only 10% of the population
is in that tail; he concludes that "the impact of an increase in income on [absolute] poverty falls roughly in
half as poverty drops from 30% to 10%, due simply to the shape of the income distribution".
23
This is also the idea behind one of the 20 EU social inclusion indicators (âLaeken indicatorsâ): the at-risk-
of-poverty rate anchored at a moment in time (year t-3, uprated by inflation over the three years).
DELSA/ELSA/WD/SEM(2005)1

18.
In some respects, however, measures of absolute income poverty are overly restrictive.
Indeed,
when family budgets are directly examined to determine the amount of resources needed to afford "decent
living conditions", the range of expenditure items broadens beyond the necessities typically considered by
absolute income measures: child-care costs, for example, hardly qualify as an essential item for meeting
the basic needs of a person living on benefits, but become important when the same persons is expected to
work. Also, the notion of relative income poverty seems to be better able to reflect risks that some
individuals are excluded from the goods and services that are customary in any given society, which is an
important dimension of social exclusion â a notion that has gained a central role in the social policy
agendas of several OECD countries.
24
For these reasons, a
relative
measure of poverty (most often based
on a threshold of half of the median income for the entire population, Annex 2) is used below as the main
poverty measure.
19.
Figure 5 shows levels of the poverty headcount, using a 50% median disposable income
threshold. In 2000, the average poverty rate across 20 OECD countries â those for which information is
available since the mid-1980s â was 10.6%, with an increase from the level recorded in the mid-1980s
(9.4%) and in the mid-1990s (10.0%). The poverty rate, on this definition, increased over the second half
of the 1990s by more than one percentage point in Australia, Austria, Finland, Ireland, Japan, New Zealand
and Sweden, while it declined by one point or more in Norway, Italy and Mexico (from higher levels in the
latter two countries). Beyond differences in trends, cross-country differences in the levels of poverty rates
remain significant, ranging from less than 5% in the Czech Republic and Denmark to values above 15% in
Ireland, Japan, the United States, Turkey and, in particular, Mexico.

The relative poverty rates shown in Figure 5, while providing a convenient benchmark for cross-
country comparisons, are however limited in two main respect. First, relative poverty is measured with
respect to an arbitrary threshold. When large proportions of the population are clustered just around this
threshold, small changes in their income can lead to large changes in headcount rates. To examine the
sensitivity of results to alternative choices of the poverty line, Figure 6 shows poverty rates measured with
respect to both the 50% thresholds and the 60% line that is now commonly used by EUROSTAT as one of
24
The notion of social exclusion is broader than that of poverty. Atkinson (1998) identifies three common
elements shared by all definitions of social exclusion:
relativity
(
i.e.
exclusion can only be judged by
looking at a personâs, or groupâs, circumstances relative to those of others in a given place);
agency
(
i.e.
exclusion implies an act by some agents, either the excluded person herself or third parties); and
dynamics
(
i.e.
exclusion reflects not just current circumstances, but dim prospects for the future).
DELSA/ELSA/WD/SEM(2005)1
22
their main indicators (âat-risk-of-poverty rateâ). Figure 6 suggests that, in all OECD countries reviewed, a
significant share of the population (8% or more in Ireland, Australia and New Zealand) is clustered
between the 50% and 60% thresholds. In Germany, Hungary and the United States, the increase in poverty
rates measured with respect to the 50% threshold over the second half of the 1990s largely reflected a
decline in the number of persons with income between 50 and 60% of the median; conversely, in Australia,
Denmark and many other countries, the increase in poverty measured with respect to the 50% threshold
over the same period was accompanied by a similar increase in poverty rates based on the higher threshold.
Persons with equivalised disposable income below 60% of the median may not be counted as poor when
assessed with respect to more conservative thresholds, but still face difficulties in making ends meet.

Second, the headcount is just one dimension of poverty. Also important is the income level of
poor individuals. Poverty gaps â the extent to which the average income of the poor falls below the 50%
median income threshold â declined in the second half of the 1990s in about half the countries
(considerably in Australia, New Zealand and Sweden) while increasing in the other half (considerably in
Austria and Ireland, Figure 7). Overall, across the 24 countries shown for 2000, average disposable income
of the poor was 29% lower than the poverty line. A synthetic measure of poverty, which takes into account
both poverty rates and gaps (Teekens and Zaidi, 1990), indicates that the income transfer needed to raise
all those living below the poverty line to that level ranged in 2000 between a high of 7% of (equivalised)
disposable income in Mexico and a low of less than 1% in the Czech Republic and Luxembourg (Figure 8).
Survey measures of income at the lower end of the spectrum are, however, less reliable than headcounts.
25
The proportion of people falling below the 50% threshold, as a share of those falling below the 60% line, is
between 50% and 60% in most OECD countries, ranging between 50% or less in the Nordic countries and
the Netherlands and 70% or more in Japan, Mexico, Turkey and the United States.

Labour markets, taxes and benefits: distributive effects on the population of working-age
22.
Determinants of income inequality and poverty differ across groups, reflecting their demographic
characteristics (
e.g.
the importance of lone parenthood) and the composition of their resources (
e.g.
the
extent to which individuals depend on earnings or government transfers for their daily living). This section
DELSA/ELSA/WD/SEM(2005)1
24
presents information about the population of working age (18 to 65).
26
First, it briefly describes the extent
to which changes in income distribution and relative income poverty for this group depart from those
observed for the entire population. Second, it discusses the relative importance of
labour market conditions
and of tax and welfare systems in shaping these trends. Third, it presents a simple decomposition of
changes in relative poverty for the working-age population according to its main proximate determinants.
3.1.
Recent trends in income distribution and relative poverty for the working-age population
23.
Persons of working age represent the largest share of the total population in all countries
reviewed. As a result â unsurprisingly â the main trends in inequality and poverty among this group largely
follow those described for the entire population. The Gini coefficient of income inequality among the
population of working-age was stable in 2000 relative to the mid-1990s on average. This, however, mainly
reflected the strong declines recorded in Mexico, Turkey and Ireland; in most OECD countries, the Gini
coefficient increased in this period, with the increase being around 10% or more in Finland and Sweden
(Figure 9).

Findings are similar when looking at relative poverty, measured with respect to a 50% median
threshold. On average, across 24 countries, 8.7% of the working-age population had income of less than
half of the median around 2000 (1 œ points lower than for the total population), with little change relative
to the mid-1990s. Relative poverty rates increased in most countries during this period, including in some
of the countries (e.g. Greece) that recorded declines in poverty rates for the entire population.
26
This age range differs from that used in other OECD publications to identify the working-age population in
order to assure consistency with internationally-agreed definitions of children (persons aged less than 18).
DELSA/ELSA/WD/SEM(2005)1

3.2.
The influence of labour markets
25.
Market income (earnings, self-employment and capital income) represents the largest component
of the disposable income of the working-age population
27
and has been â over the two decades to the mid-
1990s â the main driver of changes in income inequality (Förster and Pearson, 2002).
28
Indeed, inequality
in market income had been widening
everywhere
in the decade from the mid-1980s to the mid-1990s, a
widening that translated in several OECD countries into larger inequalities in the distribution of disposable
income (Figure 10, 1
st
panel). In this respect, the second half of the 1990s represents a significant departure
from previous trends. The employment gains that most OECD countries experienced in the second half of
the 1990s
29
have led to an increase in the share of earnings and self-employment in the disposable income
of the working-age population (on average by around 2.5 points) and to a corresponding decline in the
share of capital incomes and public transfers. Partly as a result, the Gini coefficient of market income
inequality for the population of working-age declined in around one third of the countries over the second
half of the 1990s, while it increased only marginally in most other countries: only in the Czech Republic,
Germany, Japan and Norway did market income inequality increase significantly in the second half of the
1990s (Table 4).

27
For a number of countries (Austria, Greece, Hungary, Luxembourg, Mexico, Poland and Spain), tax data
are not available separately. The analysis on market versus disposable incomes presented in this and later
sections is therefore restricted to a sub-set of countries.
28
The Gini coefficient for market income increased by around 9% in the period from the mid-1970s to the
mid-1980s (across 7 OECD countries) and by 11% in the period from the mid-1980s to the mid-1990s
(across 14 countries), while it was almost stable (an increase of less than 1%) in the second half of the
1990s.
29
The employment to population ratios among the working-age population, across the OECD area as a
whole, increased from 64.3% in 1995 to 65.7% in 2000. Two-thirds of the countries registered an increase
in employment rates, with increases of 5 points of more in Ireland, the Netherlands, Spain, New Zealand
and Norway (OECD, 2003).

26.
The influence of labour market conditions on inequality and poverty at the level of market
income reflects changes in both the weight of earnings, self-employment and capital income, and in the
degree of inequality of each component. In almost all countries covered in this paper, self-employment
and, in particular, capital income are more unequally distributed than earnings. Annex Table A.4 provides
one measure of the degree of inequality in the distribution of the individual components of market income,
i.e.
the share of earnings, self-employment income and capital income going to the bottom, top and middle
quintiles of the working-age population. In most countries, the bottom quintile of the working-age
population receives between 4 and 5% of all earnings (3% or lower in Australia, New Zealand and the
United Kingdom) while the top quintile receives some 40%. Both self-employment income and capital
income are more concentrated towards both tails of the distribution than earnings (between 6 and 7%
accrue to the bottom quintile, and as much as 50% goes to the top quintile). Over the second half of the
1990s, however, the share of earnings going to the lower quintile increased in many countries, often after
declines in the previous decade.

The relationship between labour markets, on one side, and income inequality and poverty, on the
other, is crucial for social policies. At the level of individuals, higher employment increases the well-being
of those at greatest risk of social exclusion and poverty. Across countries, those with lower non-
30
This is not the case of self-employment and capital incomes: their share going to the bottom (and often the
middle) quintile decreased in most countries in the late 1990s, while that going to the top quintile increased
(Anglo-Saxon countries being an exception), continuing the trend of the previous decade.

employment rates (in particular for women) experience lower poverty rates
at the level of market income
among the population of working age (Figure 11, panel a). The relationship is stronger when account is
taken of the way in which employment is distributed among households, as countries with similar levels of
employment (
e.g.
Japan and Australia, where employment-to-population ratios are slightly above 70%)
show large differences in the share of the working-age population living in households where no adult
works (ranging from less than 3% in Japan to more than 13% in Australia).

no one works. Exact years are those specified in the note to Table 1.

28.
While cross-country differences in the extent of non-employment and joblessness go a long way
towards explaining differences in market income inequality, the
quality of jobs
also matter, especially for
those in the lower tail of the distribution. Jobs are increasingly diverse, and some of them provide little
protection from risks of poverty. While the risk of falling into poverty is much higher for households with
no adult in employment than for those where someone works, households with one or more workers
represent a very substantial proportion of the income-poor in all OECD countries.
31
Even households with
two or more workers are not immune from the risk of inadequate income, especially in Austria, Greece,
New Zealand, Portugal, Switzerland and the United States. Further, since 1995, the share of income-poor
households with at least one worker has increased in around half of the countries shown in Figure 12.
31
However, this partly reflects the inclusion â among household with workers â of the self-employed,
whose income is often under-recorded in household surveys, as well as of people with part-time and part-
year jobs. With reference to the latter, persons who worked full-time full-year in the United States in 1999
had an (absolute) poverty rate of 2.6%, as compared to 13% for those who worked either part-time or for
only part of the year and 20% for those who did no paid work at all during the year (Freeman, 2001).

3.3.
The role of taxes and public transfers
29.
The relationship between employment levels and relative poverty at the level of
disposable
income
, however, does not follow simple patterns: in other terms, countries where non-employment
(among individuals) and joblessness (at the household level) are lower do not consistently show lower rates
of relative income poverty. This is because, beyond the levels
and
quality of jobs, government policies play
a significant role in accelerating or moderating trends in income distribution and poverty. The relationship
between government policies and poverty outcomes is striking: across countries, relative poverty rates
among the working-age population are lowest where (non-health) social spending on the working-age
population is highest (Figure 13).
32
Within each country, the combined effect of the tax and benefit
systems is to lift out of relative income poverty more than half of the population at risk, on average
(Figure 14). This effect, which ranges between around one-fourth of those below the poverty threshold
before taxes and transfers in the United States and more than two-thirds in Denmark, declined however
over the second half of the 1990s in most OECD countries, as the growth of real benefits most often lagged
that of median disposable income.
32
Other means through which governments influence poverty and income inequality include policies aimed
at changing the distribution of skills among the population (in particular, at increasing the earnings
potential of those most exposed to poverty risks), at supporting the earnings of workers at the bottom of the
pay scale (for example through minimum wage provisions), and at addressing the specific barriers to
labour farce participation faced by disadvantaged groups.

Effect of taxes and transfers in reducing poverty

30.
Both taxes paid by the population of working-age (income and payroll taxes) and public transfers
received by the same group reduce inequalities in the distribution of disposable income: taxes are mainly
DELSA/ELSA/WD/SEM(2005)1
30
paid by the richer, while public transfers mainly accrue to the poorer. An indicator of the relative role of
taxes and transfers in reducing income inequalities ("pseudo"-Gini coefficient of each of the income
components) shows that, in all countries, taxes are more concentrated than transfers, although the extent to
which this is the case declined over the second half of the 1990s.
33
The extent of concentration of public
non-pension transfers to persons at the bottom quintile of the income scale increased significantly in the
second half of the 1990s in most countries, continuing a trend already observed in the previous decade,
while declining only in Greece, Germany, Luxembourg, Ireland and Poland (Annex Table A.5). In turn, the
proportion of non-pension transfers accruing to the six middle income quintiles decreased in most
countries and on average, while changes at the top have been much less pronounced. Changes have been
smaller in the case of taxes, with greater concentration of taxes at the top of the income distribution in a
majority of countries, but reductions in Australia, France, Ireland, Japan, Portugal and the United States.
3.4.
Accounting for changes in poverty rates since the mid-1990s
31.
Although both taxes and public transfers reduce income inequality and poverty at a point in time
â for a given distribution of market income â they also distort decisions of private agents in terms of
employment and work efforts. Marginal effective tax rates, which are one cause of these distortions, are
typically high at both ends of the income distribution, and they may contribute to poverty traps among
many individuals relying on benefits as well as to reductions in work effort, or attempts to escape taxation,
by individuals with high earnings. Reforms implemented by several OECD countries during the second
half of the 1990s (generally in the form of earnings top-up for low-paid workers, and of greater pressures
put on persons relying on benefits to take up suitable employment offers) have aimed at reducing these
distortions so as to improve work incentives for individuals with low income.
32.
How have these reforms affected changes in poverty? Efforts to address this question have
typically followed two tracks. The first relies on individual records, assessing what poverty rates would be
today if the structure of wages, hours of work, and government benefits had remained at some base-year
level; while this approach does not account for behavioural changes following reforms, it allows tracking
the same individual over time.
34
A second approach, which is easier to implement when comparing a large
number of countries, relies on aggregate data.
35
This approach is used here to account for changes in
relative poverty rates among individuals living in households with a working-age head. A simple shift-
share analysis is used to decompose changes in relative poverty rates into three components:
âą
the part due to changes in market-income poverty for each group, while keeping constant both
population structure and the effectiveness of taxes and transfers in reducing poverty;
33
The only exceptions are Germany, New Zealand, Norway and the United States. Italy is the only country
where public transfers to persons of working age are unequally distributed (i.e. higher income groups
receive a larger share than lower-income ones), reflecting the importance of earnings-related pensions
(which tend to increase with income) received by persons of working-age.
34
Based on this approach, Dickens and Ellwood (2001) argue that demographic conditions (e.g. a greater
incidence of single-parent households), earnings structure (e.g. wider earnings distributions) and work
efforts (i.e. the combined effect of changes in activity rates and hours worked) account for a similar share
of the increase in relative poverty in the United Kingdom from 1979 to 1999, while greater generosity in
government benefits contributed to reduce poverty rates over the same period; in the United States, the
increase in relative poverty over the same period mainly reflected demographic changes and, to a less
extent, changes in earnings structure; higher work efforts contributed to lower poverty, while changes in
government benefits did not exert significant influence in either direction.
35
Most often, studies using aggregate data regress poverty rates against a range of possible determinants, and
use results to compare situations at two points in time. However, results from this type of analysis have
been found to be typically unstable and sensitive to the specification used.
DELSA/ELSA/WD/SEM(2005)1
31
âą
the part due to changes in the effectiveness of taxes and transfers in reducing market-income
poverty for each group, for given population structure and market-rate poverty; and
âą
the part due to changes in population structure, for given market-income poverty and
effectiveness of tax and transfers in reducing poverty of that group.
36
While mechanical decompositions of this type cannot reflect the complex interrelations between each
pair of variables
37
, and the effects of various factors on the income of each individual, they do provide a
convenient summary of the relative role played by various factors.
38
At the same time, however, the
detailed breakdown used for this decomposition may imply that results are affected by the small sample
size of surveys.
33.
Figure 15 shows results applied to changes in relative poverty rates for persons living in
households with a head of working-age over the second half of the 1990s, with population broken down by
work attachment of adult members (i.e. no adult in the household working, only one adult working, and
two or more adults working). In the case of Australia, for example, relative poverty rates of persons living
in households with a head of working age increased by 1 point in the second half of the 1990s (shown with
a "diamond" in Figure 15): changes in market-income poverty and in the relative size of the three types of
households (a slight decline in the share of persons in households where no one works) contributed to
reduce poverty rates (by 0.4 points in the first case, marginally in the second) but their effect was more
than offset by a (1.4 point) reduction in the poverty-reducing effect of taxes and transfers. (The sum of the
3 bars for each country equals the change in the relative poverty rate).
34.
Figure 15 suggests that, while reforms to taxes and transfers systems introduced in the second
half of the 1990s may have contributed to higher employment and lower market-income poverty in several
countries, their effects were often offset by a smaller impact of taxes and transfers in reducing poverty.
Overall, despite much diversity in country experiences in terms of overall changes in poverty rates, higher
market-income and changes in population structure (declines in the share of workless households and
increases in that of two-worker households) contributed to lower total poverty in a majority of countries
(with the exception of Germany, Japan, New Zealand and Portugal, in the first case; and of Finland and
Germany in the second) over this period. However, in most cases these positive developments were offset
by a reduction in the effect of taxes and transfers in reducing poverty (with the exceptions of France,
36
In this exercise, the aggregate poverty rate, at the level of disposable income, is expressed as a weighted
sum of group-specific poverty rates, with these rates expressed as the product of market-income poverty
and of a coefficient expressing the effect of taxes and transfers in reducing market-income poverty.

the poverty count, changes in one variable are multiplied by the average value (between two points in time)
of the other two variables (to avoid explicit consideration of interaction terms between each pair of
variables).
37
Changes in benefit level, for example, may encourage previously inactive individuals to take-up jobs,
leading to positive effects (i.e. a reduction is poverty) for both household structure (decline in workless
households) and market-income poverty (higher earnings as former benefit recipients enter employment).
38
Danziger and Gottshalk (1995) apply a shift-share decomposition to changes in (absolute) poverty in the
United States from 1949 to the early 1990s; they concluded that changes in income for each demographic
group dominate, while changes in the demographic composition played a minor role.

40
In interpreting these results, it should be noted that a "smaller"
poverty-reducing effect of net public transfers may reflect an increase in real benefits lagging that of
median disposable income, and lower benefit take-up, rather than cuts in the value of benefits in real terms.

Poverty and inequality among children and households with children
35.
Poverty is a special concern when it affects individuals who cannot be held responsible for their
situation and who are especially vulnerable to its consequences. These considerations have led to the
explicit formulation of policy "targets" for child poverty in some OECD countries (
e.g.
the United
Kingdom) and to greater attention paid to children in the social policy agendas of most of them.
41
This
39
In Germany, reforms introduced in 1996 increased child benefits and social minima (
Steuerfreies
Existenzminimum)
.
40
When looking at the household structure of the population (number of children and of adults present in the
same households, i.e. four groups), this analysis also suggests that changes in population structure
contributed to increase poverty in Australia, Germany, Netherlands, Sweden and the United Kingdom
(mainly because of more persons living alone) and to reduce it (marginally) in the United States.
41
In the United Kingdom, a quantified target has been set to reduce the number of children living in low-
income households by a quarter by 2004-05 as a contribution to the broader target of halving child poverty
by 2010 and eradicating it by 2020. In Canada, the commitment was to "seek to eliminate child poverty"
but no definition or indicator was agreed. The "New Zealand's Agenda for Children" (June 2002) embodies
a commitment to eliminate child poverty. Among other EU countries, the setting of targets for child
poverty is explicit in the National Action Plan of Greece, while other countries (e.g. Germany) have set
targets in areas that may have an important impact on child poverty (such as cutting the number of youth
not having obtained vocational qualifications by half by 2010).
DELSA/ELSA/WD/SEM(2005)1
33
section looks at the recent record of OECD countries with respect to poverty among children and their
families. It should be stressed, however, that results described below are critically shaped by how we adjust
household income for household size (using the square root of household size): other assumptions about
household equivalence of scale, for example, may significantly reduce the number of children that are
counted as poor in any country.
4.1.
Levels and trends in relative income and poverty
36.
On average, across 23 OECD countries, around 12% of all children fell below the (50%) poverty
threshold in 2000, an increase of close to 1 point relative to the level of the mid-1990s. Child poverty rates
are especially low in the Nordic countries, where fewer than 4% of all children are poor, followed by
France, Switzerland and the Czech Republic, with rates of around 7%. Child poverty is high in Mexico,
Turkey and the United States, where it exceeds 20%, but also in Ireland, Italy, New Zealand, Portugal and
the United Kingdom, where it is above 15% (Figure 16). Austria and New Zealand experienced significant
increases in child poverty in the second half of the 1990s, while Italy recorded a significant decline.
37.
In most countries, relative poverty rates among children are also higher than for the entire
population (Figure 16), but with much variation across countries: in the Nordic countries and Belgium,
child poverty rates are between œ and
â
of the overall rate, while in the Czech Republic, the Netherlands,
Hungary and New Zealand child poverty rates exceed overall poverty by 50% or more. These differences
suggest that specific factors increase risks of poverty for children in some OECD countries.

The influence of household structure, mothers employment and benefit systems
38.
While several factors contribute to child poverty, three of the most important relate to the
characteristics of the households where children live, to the employment status of their mothers, and to the
role of taxes and transfers in reducing poverty risks. With reference to the first factor, the equivalised
42
On average, children constitute around a quarter of the poor population, with this share being 15% or less
in Nordic countries, and 35% or more in the Czech Republic, Mexico, New Zealand, Poland, Turkey and
the United Kingdom.
DELSA/ELSA/WD/SEM(2005)1
34
disposable income of households with children (and a head of working age) is, on average, slightly above
80% of that of households with no children: the relative income of households with children is highest in
the Nordic countries and Belgium, and lowest in Mexico and, to a lesser extent, Australia, New Zealand,
Portugal and Turkey (Figure 17). Households with children generally have higher rates of relative poverty
than those without children, and this difference increased over the past two decades.
43
Among households
with children, relative poverty rates are highest among single parents â at 40% or more in Australia,
Canada, New Zealand, the United Kingdom and the United States, and over 50% in Ireland, Japan, Spain
and Turkey â and, during the past 15 years, this increased the most in France, the Netherlands, New
Zealand and the United Kingdom (while they it in some Nordic countries).

39.
In many countries, however, it is not living in single-parent households
per se
that increases
poverty, but rather the employment status of the parent. On average, the poverty rate for single parents (at
32%) is three times higher than for all families with children; however, among those where the single
parent is jobless, the poverty rate reaches 57% (while it falls to 21% among those where the parent is
employed). Having an employment therefore reduces poverty risks among single parents by more than
60%, although Greece, Japan and Turkey are notable exceptions. In several countries â notably the
Australia, Italy Norway and Sweden â the poverty rate among single parents with a job is not that much
different from the overall rate for families with children (Figure 18). Having a job also reduces the
probability of falling into poverty for couples with children (by almost Ÿ in the case of couples where both
parents work, relative to those where only one parent does). Because of these patterns, OECD countries
with higher employment rates among mothers also experience lower rates of child poverty (Figure 19).
43
On average, across 20 OECD countries, relative poverty rates of households with children were 17%
higher than those of households without children in the mid-1980s, 22% higher in the mid-1990s, and 27%
higher in 2000.

Changes in household composition â in terms of both household types and work attachment of
different households â have influenced trends in poverty rates for households with children. Table 4
compares relative poverty rates for households with children in the mid-1990s and 2000 (1
st
and 2
nd
columns) in each country with those that would have prevailed had household structure remained as in
1985 (4
th
and 5
th
columns); rates under "unchanged population structure" refer to relative poverty rates
under assumptions of constant shares of single and couple families, as well as of constant shares in
households with no, one and two or more workers. In most countries, differences between actual and re-
weighted rates are less than one percentage point in 1995, and below 2 points in 2000. Changes in
household structure since the mid-1980s (3
rd
and 6
th
columns) have worsened trends in relative poverty for
households with children in ten countries: Australia, Denmark and Norway (dampening the decline) as
well as in the Czech Republic, Finland, France, Japan, Germany, New Zealand and the United Kingdom
DELSA/ELSA/WD/SEM(2005)1
36
(accentuating the increase). In the remaining 11 countries, changes in household structure have tended to
smooth changes in relative poverty among households with children.

Actual population structure
Unchanged population structure
Notes:
Poverty thresholds at 50% of the median income for the entire population. Re-weighted poverty rates are calculated by holding
constant the shares of five household groups (single parents with and without work, two or more adult households with children with
no worker, one and two or more workers) at the mid-1980s level (1990 level in the Czech Republic and Portugal). Patterns highlighted
are only proximate, as they do not allow for changes in poverty thresholds as household structure varies. Exact years are those
specified in the note to Table 1.

41.
The last factor impacting on poverty among households with children is the tax and benefit
system. While taxes and transfers reduce the extent of relative income poverty among all households, their
effect is significantly lower in the case of households with children. On average, across 18 OECD
countries, taxes and transfers lift out of market-income poverty more than half of the persons in households
without children, but only 44% of those in households with children (Figure 20); the effects of taxes and
transfers in reducing poverty among households with children is especially low in Japan, Italy and
Portugal. Indeed, while tax and benefit systems in all OECD countries provide preferential advantages to
households with children, these advantages are smaller than estimates of the higher household costs of
larger families that are implicit in the elasticity used in this (and most others) studies to equivalised
household income.
44
44
The impact of taxes and transfers in reducing poverty also varies across different types of households with
children. In most OECD countries, taxes and transfers have the largest poverty-reducing effect on
households with children without work. Changes in patterns of support since the mid-1990s are limited.

Income adequacy in old age: effects of pension reforms on the retirement-age population
42.
Most persons of retirement age (above 65) have withdrawn from the labour market, and depend
on pensions and capital income for much of their daily living. Differences in the structure of their income,
as compared to persons of working age, alter the mix of factors that most influence income inequality and
relative poverty among those belonging to this age group.
5.1.
Levels and trends in relative income and poverty among the elderly
43.
Recent trends in income distribution and poverty among the elderly need to be described against
the backdrop of longer-term trends towards significant improvement in their economic situation. Past
OECD studies have highlighted steady gains in the relative incomes of prime-aged and elderly persons â
especially those around retirement-age â in all OECD countries, as well as declines of their relative poverty
rates â both in absolute terms and relative to other age groups (e.g. OECD 1998, OECD 2001, Förster and
Pearson 2002). Historically, income inequality among the elderly population has also tended to be lower
than among the population of working-age, and to decrease â or to increase by less â over time.
44.
Changes since the mid-1990s suggest some departures from these long-term patterns. Annex
Table A.6 presents data on the income of individuals by age, relative to that of the entire population, and
changes in that profile since the mid-1990s and mid-1980s.
45
While the shape of equivalised disposable
income by age of individuals is well established â higher relative income until an age of 41 to 50, followed
by steady declines in later years â changes for the OECD average since 1995 suggest that:
âą
Relative incomes of youths (18 to 25) continued to fall as in the previous decade, but at a much
lower pace. Children (aged less than 18) experienced small increases in their relative income, as
compared to virtual stability in the previous decade.
45
These data on relative incomes take into account changes in population shares: an increase in the share of
the elderly (with lower income) will depress overall income and suggest an increase in their relative
position that only reflects their higher weight in the population. To avoid this potential bias, Annex Table
A.6 uses a constant population structure at the base year to describe changes in relative income by age
groups.
DELSA/ELSA/WD/SEM(2005)1
38
âą
Prime-age adults (aged 41 to 50) experienced significant losses in relative income in the second
half of the 1990s, which exceeded the gains of the preceding decade.
âą
Persons in later working-life (51 to 65) experienced further improvements in their relative
incomes.
âą
Elderly persons (66 to 75) recorded small declines in their relative income, which contrast with
significant gains in the previous decades, while the relative position of the very elderly (76 and
over) was broadly stable.
45.
Declines in the relative income of persons aged 66 to 75 over the second half of the 1990s
occurred in about half of the countries reviewed, and were particularly evident in Canada, France,
Hungary, Luxembourg and Sweden (between 5 and 7 percentage points). In most of these countries, these
declines followed improvements recorded over the 1980s. Recent trends are more diverse for the very
elderly: these experienced substantial increases in relative incomes (6 points or more) in Austria, Greece
and Turkey, but large falls in Finland, Ireland, Italy, Poland and Sweden.
46
A more generalised decrease in
relative incomes is experienced by adults aged 41 to 50, with the exception of Finland, Greece, Japan and
Portugal. âQuasi-replacement ratesâ for younger senior citizens,
i.e.
income levels of those aged 66-75
relative to that of persons aged 51 to 65, are â in most OECD countries â between 70 and 80%, and close
to 90% in Austria, Poland and Turkey (Figure 21); and they fell in a majority of OECD countries â in
particular in Canada, Finland, France, Hungary, Luxembourg and Sweden â in the second half of the
1990s.

Note:
Quasi-replacement rates are defined as the mean disposable income of persons aged 66 to 75, relative to the
mean disposable income of persons aged 51 to 65. For calculating relative income changes, population shares have
been kept constant at the value recorded at the beginning of the period (mid-1980s, except for Czech Republic,
Hungary, Poland and Portugal, where this is 1990). Data for Germany refer to old LĂ€nder. The OECD average refers to
the average of 17 countries for which information is available in all three years (except Mexico and Turkey). Exact
years are those specified in the note to Table 1.

Some of the limits in using "current income" for assessing well-being of the elderly are discussed in Box 3.
DELSA/ELSA/WD/SEM(2005)1
39
46.
Differences across countries in the relative income of elderly people reflect differences in both
family structures and in social protection systems. The role of family structures is highlighted by looking at
households with a head of retirement-age (Figure 22). Individuals living in these households represent
roughly 16% of the total population across the 24 countries shown, and their share exceeds by around 8%
that of all elderly individuals.
47
Beyond its size, there is much variation in family types. While in Greece,
Mexico, Portugal and Turkey more than 80% of persons belonging to households with a retirement-age
head live in households with two or more adults (i.e. couples of two elderly persons, or households
composed of different generations), this proportion is less than 60% in Nordic countries. On average,
around a third of all persons living in households with an elderly head in 2000 were living alone, and most
often this person was not working. Elderly persons living alone are predominantly women, reflecting
higher life-expectancy in old age and lower probability of entering a new union after separation or death of
their partner. Across the OECD countries covered, only one out of four persons living in households with
an older head was in employment. There is, however, significant variation across countries in this share,
which ranges from less than 7% in the Czech Republic, Finland, Poland and Switzerland, to 40% or more
in Greece, Ireland, Japan, Mexico, Portugal, Turkey and the United States.
48
These differences are likely to
mainly reflect the frequency of "work" (often part-time and occasional) following retirement from a
person's main career, rather then delayed retirement from a full-time job until later ages.

This reflects the existence, within households with a retirement-age head, of younger spouses and â less
often â their children. The ratio between persons living in households with a retirement-age head and the
elderly population varies widely across countries, between values of 80% or less in Hungary and Poland â
where many elderly live with their offspring â and 130% or more in Ireland and Portugal â where many
teenagers and young adults continue to live in the parental home. These differences across countries may
also reflect differences in the definition of "household heads" used in various surveys.
48
This share can reflect different situations, as family members with jobs can be either younger persons
living in a multi-generational household, or elderly workers themselves. The first pattern is more common
in Mexico and Southern Europe, the second in Anglo-Saxon countries.
49
The "work status" of different household types is defined on the basis of the presence or absence of
earnings and self-employment income, rather than on the "self-reported" perceptions of survey respondents
(with the exception of Germany).
DELSA/ELSA/WD/SEM(2005)1
40
47.
Differences across countries in the structure of income of the elderly are also important. Public
transfers (mainly old-age pensions) and capital income represent the largest components of the disposable
income of the elderly representing, respectively, about two thirds and close to 30% of disposable income
across the 17 countries for which information is available on all income sources (Annex Table 8). There is
some evidence of a reduction in the share of public transfers in total income in about half the OECD
countries. In several countries, the tax burden on elderly people also declined, in particular in Denmark, the
Netherlands and New Zealand. The share of earnings (including self-employment income) in total income
of the elderly remained stable on average, while increasing significantly in Ireland and New Zealand an
decreasing in the Czech Republic, Hungary, Poland, Portugal and, in particular, Japan. The share of capital
income slightly increased, in particular in some European countries.
48.
Changes in family types and income structure have affected both income inequality and relative
poverty among the elderly. In a majority of countries (Greece, Ireland, Japan, Mexico, Portugal,
Switzerland, Turkey and the United States are exceptions), income inequality among the elderly (Gini
coefficients) remains lower than among the population of working age;
50
and was broadly constant (on
average) both in the decade from the mid-1980s to the mid-1990s and in the second half of the 1990s
(although it increased slightly in Denmark, Finland, Ireland and New Zealand, Figure 23). Their relative
poverty rate, at around 14% in 2000 across the 23 countries for which longer-trend data are available,
decreased by 1 œ points between the mid-1980s and mid-1990s and remained broadly stable during the
past 5 years
51
(Figure 24) â although, when excluding Mexico and Turkey, it increased by almost 1
percentage point over the second half of the 1990s. However, cross-county averages hide great diversity of
experience, with almost as many countries experiencing a decline in old-age poverty as those witnessing
increases. In Ireland, the large increase in relative poverty rates among the elderly reflected strong growth
in median income in real terms, and the failure of elderly income to increase at the same pace, rather than
lower economic conditions among the elderly
per se
. Moreover, assessing resources in retirement through
monetary income may exaggerate poverty risks for the elderly, as it does not take into account lower work-
related expenditures and housing costs following retirement, and higher asset holding among the elderly
(Box 3).
50
This has not always been the case: in the mid-1970s, inequality among the elderly was higher than among
the working-age population in nine of the ten countries for which information is available; and in the mid-
1980s, this concerned 12 of the 20 countries.
51
Among the elderly, those aged 76 and above have a much higher poverty risk than those aged 66 to 75, in
almost all OECD countries (see Annex Table A.7)
DELSA/ELSA/WD/SEM(2005)1
41
Box 3. Housing costs and poverty outcomes
Most international comparisons of inequality and poverty among the elderly â including those presented in
this paper â are based on current income. The capacity of households to respond to needs, however, depends on both
income and expenditure. Housing costs, in particular, are the largest single component of household spending, and are
a significant determinant of household ability to make ends meet. Government policies affect housing costs through
both provision of subsidised housing to low-income groups, and through tax advantages to encourage home
ownership. Some OECD countries (e.g. the United Kingdom) have translated the recognition of the importance of
housing costs into the adoption of measures of poverty, both before and after housing costs.*
As patterns of home ownership differ both across demographic groups (being higher among the elderly than
among persons of working age) and countries (higher in Anglo-Saxon and Southern European countries than in Nordic
and Continental European countries), housing costs significantly affect comparisons of the extent of poverty. An
indication of the impact of housing costs is provided by the figure below, which uses matched data from income and
expenditure surveys in Australia and Finland around the mid-1990s (Ritalkallio, 2003). This poverty measures relies on
thresholds defined both before and after
actual
housing costs (expenditures for heating, electricity, water, repairs and
maintenance, mortgage repayments and interest costs): in the case of the âafter-housing-costsâ poverty, the threshold
is defined as 50% of (average) equivalised disposable income less the (average) equivalent rent paid by renters.
Panel
a
, which shows poverty rates and gaps (i.e. the shortfall of the disposable income of the poor from the poverty
line), shows that consideration of actual housing costs reduces poverty rates but increases poverty gaps in both
Australia and Finland, significantly narrowing differences between the two countries. Panel
b
, which shows poverty
rates among individuals of different ages, shows that consideration of housing costs lower poverty rates among the
elderly, to a point where their poverty risk is lower than that of youths.

* Consideration of housing costs in the measurement of poverty raises the difficult issue of how to measure support provided by
governments through housing provided at subsidised rents. Changes in the form of government support (i.e. from social housing to
housing cash benefits), as implemented in several OECD countries over the 1980s and 1990s, could distort assessment of trends in
poverty (i.e. increases in cash income that do not correspond to improvements in the situation of low-income families
).

Relative income poverty among the elderly tends to be concentrated among the very old and
those living alone. Elderly people living alone and not working are, in all countries, at greater risk of
poverty than other elderly, and this risk increased in the second half of the 1990s in Australia, Denmark,
Finland, Germany, Sweden, the United Kingdom and the United States. Most of these are women, often
widows with limited or no own pension entitlements. As a result of changes in both poverty risks and in
the shares of the various household types, elderly persons living alone and not working make up the largest
share of the poor in many OECD countries (Figure 25). However â in Canada, Greece, Ireland, Japan,
Poland, Portugal, the United Kingdom and the United States â many poor elderly are both living with a
partner and in a household with earnings. Conversely, in all countries, persons living alone and working,
and those where both adults work, represent a small proportion of the poor.

5.2.
Public pension systems and their impacts on the elderly population
50.
Given their weight in the disposable income of elderly people, public pensions play a major role
in shaping income adequacy and poverty risks for this group of the population. When considered together,
public transfers and taxes reduced inequality and poverty among the elderly in 2000 by more than they do
with respect to the population of working-age. However, in a majority of countries this effect weakened
over the second half of the 1990s (with the exceptions of the Czech Republic, France, Italy, Portugal and
Sweden with respect to income inequality; and the same countries except Sweden but including the
Netherlands and Norway with respect to poverty).
51.
Outcomes in terms of relative poverty among the elderly are affected by several features of
public pension systems. The amount of spending on old-age pensions (public and private mandatory
spending), however, does little by itself to influence poverty among the retirement-age population.
Figure 26 highlights no relationship across countries (panel
a
): in fact, some of the countries with higher
spending on old-age pensions (e.g. Italy, France and Germany) experience higher poverty rates among the
elderly than countries with much lower spending levels. This lack of association between pension spending
and poverty outcomes reflects the importance of earnings-related pensions, and differences in the ceilings
that are applied to high earnings. Indeed, where pension benefits increase in line with previous earnings,
they may have a regressive impact on income distribution and relative poverty among the elderly.
52.
Other features of pension systems are likely to matter more for poverty outcomes among the
elderly than aggregate spending, although the co-existence in a point in time of different rules applying to
various groups of persons make it difficult to disentangle their importance.
52
Among the features that are
52
Among these pension parameters is whether benefits are indexed to prices, earnings, or some combination
of the two. In order to control expenditures, several OECD countries moved over the 1990s from wage to
price indexation, a move which may tend to increase relative poverty among the elderly over time. To
DELSA/ELSA/WD/SEM(2005)1
44
most obviously related to poverty outcomes are pension floors provided by public pension and welfare
systems. OECD countries vary significantly in the tools they use to minimise poverty risks among the
elderly: some rely on âminimum pensionsâ, limited to persons with past contributory records, others on
"basic" pensions, provided to all elderly citizens irrespectively of past contributions (but often subject to
residence and means tests), and others yet on the general social assistance schemes applying to the entire
population. In general, countries where pension floors â expressed as a ratio of the poverty line â are
higher tend to display lower relative poverty rates among the elderly (panel b); the relation is however
weak, as other characteristics â
e.g.
the extent to which the elderly share in the resources of extended
households â impact on relative poverty in old-age.

53.
Despite the lack of a significant association between pension spending and poverty across
countries, changes in the generosity of public transfers and taxes have played the largest role in shaping
changes in poverty risks among the elderly within individual countries. Figure 27 applies the same shift-
share analysis described in Section 3 to changes (over the second half of the 1990s) in relative poverty
rates among persons living in households with a retirement-age head, broken down by whether individuals
are living alone or with other adults, and by the work status of household members. It suggests that, in all
countries where changes in relative poverty rates are significant, they have been driven by changes in taxes
and public transfers received by this group. Changes in the population structure have generally been minor,
while changes in market income have tended to reduce risks of poverty in Australia, Canada and Finland,
and to increase it in Japan and the United States. As in the case of the working-age population, a positive
contribution of taxes and public transfers to higher relative poverty among the elderly may reflect increases
in real benefits that lag those of median income, rather than declines in the real value of benefits.
offset this effect, some countries have introduced specific measures to protect those more exposed to
poverty risks (e.g. the Minimum Income Guarantee in the United Kingdom).

Data are based on a shift-share analysis applied to population living in households with a head of retirement-
age, broken by work attachment of household members (i.e. distinguishing between households with no workers, with
one adult working, and with two or more adults working). The sum of the three components (shown as bars) is equal to
the total change in poverty rate (shown as a "diamond"). Exact years are those specified in the note to Table 1.

5.3.
Distributive patterns of public transfers and private capital income
54.
The distribution of public transfers (mainly old-age pensions
53
) and capital income (which
includes private and occupational pensions) differs in important ways.
54
Because of these differences,
53
On average, about 90% of public transfers going to the elderly are made up by old-age pensions, with
somewhat lower shares in the Anglo-Saxon countries and close to 100% in Continental European
countries. These differences, however, may partly reflect differences in classification of income transfers
across countries.
54
The measurement of income from occupational and private pension schemes raises difficult issues.
According to the recommendations of the âExpert Group on Household Income Statisticsâ (the Canberra
Group), current transfers received by households (âpayments and receipts which are made without a
matching
quid pro quo
in the period in which they are paid/receivedâ) should include âemployment-related
pensions and other insurance benefits paid from private employerâs schemesâ and âgovernment schemes
run entirely for benefit of government employeesâ, while excluding âlump-sum retirement payoutsâ
(recorded as capital transfers) and âbenefits from private insurance schemes where... participation in the
scheme is entirely at the discretion of the contributorâ (the latter being recorded as either non-life
insurance, outside the scope of income, or as property income, when akin to payments from an annuity or
similar investment instrument). In practice, it is unclear to what extent these conventions are strictly
followed. As a result, because of the wide variety of private pension arrangements in OECD countries,
benefits from private pension funds that are substantially similar may be classified differently by various
countries. For the purpose of this analysis, private and occupational pensions are recorded among âcapital
incomes", although there are exceptions (Austria, the Czech Republic, Hungary, Italy and Mexico; in these
countries, however, private pensions remain relatively under-developed).
DELSA/ELSA/WD/SEM(2005)1

reforms aimed at increasing the diversification of income sources in retirement may have distributive
implications. One way to assess distributive patterns of public transfers and capital income is through
âpseudo-Lorenzâ curves. Figure 28 show these curves for public transfers (black dotted line) and capital
income (black continuous line) among the retirement-age population, as well as that for disposable income
of the working-age population (dashed line). The latter displays a familiar shape: on average, around 3% of
disposable incomes accrue to working-age individuals in the lowest decile, 8% to those in the two lowest
deciles, and around one fourth to persons in the highest decile of the working-age population.
55.
The extent to which pseudo-Lorenz curves for public transfers depart from the pattern for
disposable income of working-age persons varies across countries. In countries where public pension
systems are mainly earnings-related, as in the case of France, the (dotted) line for public transfers follows
closely the (dashed) line for disposable incomes of persons of working age. In Canada, Ireland, the
Netherlands, New Zealand and the United Kingdom, on the other side, pseudo-Lorenz curves for public
transfers are close to the 45° line, as all persons receive a similar public pension. In Finland, public
pensions are distributed progressively (the pseudo-Lorenz curve lies above the 45°line), as the share that
goes to individuals in the lowest deciles exceeds that accruing to those at the top of the distribution. In
Australia and Ireland, the middle deciles seem to profit relatively more from public pensions than both the
poor and the rich. Despite these differences, however, public pensions are â on average and in all countries
â more equally distributed than disposable income of the working-age population.
56.
Private capital income of the elderly is far more unequally distributed than public transfers. In
Italy, for instance, more than 80% of this income source goes to the top 20 % of the retirement-age
population and this percentage exceeds 65% in the Czech Republic, Greece, Luxembourg and New
Zealand. On average, a little over 10% of private capital income accrues to the poorer half of elderly
people, while more than 40% accrues to the top decile. In general, over the past five years, the share of
private pensions and capital incomes in total incomes of the elderly increased in about half of the countries
under review. In the case of Finland, this increase took place about equally across all income groups; in
other countries, however, this increase affected primarily richer and middle income groups (
e.g.
Denmark,
Germany, Luxembourg, Ireland, Italy, Japan and the United Kingdom, Annex Table A.8).
57.
Evidence on the distributive pattern of public and private income sources underscores the extent
to which resources of older people continue to be highly differentiated across the income ladder. On
average, across the OECD countries reviewed in this paper, public transfers still account for almost
all
of
the disposable income of the bottom quintile of the elderly population (Figure 29) and close to 80% of the
incomes of the middle 60% of the distribution. Only individuals in the top quintile of the distribution enjoy
a âbalancedâ mix of income streams, where public transfers, private capital income, and earnings contribute
about equally. Country differences around this average, however, are significant. In Finland, for example,
the share of occupational pensions â which are included here among capital income â constitutes some
70% of the disposable income of the elderly, as compared to only 20% for public pensions, and are
distributed much more equally than in other countries. This reflects the more institutional role of such
pensions in the Finnish retirement system â and their management by social security institutions.

ANNEX 1. CHARACTERISTICS OF THE DATA USED IN THE ANALYSIS
58.
This annex describes the main features of the data used in this paper: both those that are common
to the datasets of different countries and those that differ across countries and that are likely to distort
comparisons. The basic concept underlying the data and indicators presented in this paper is that of
household disposable income
. To account for possible scale economies in consumption, household income
is "equivalised" using the square root of household size.
55
Information is presented for various breakdowns
of individuals and households: age of individuals, in the first case; age of the household head (below and
above 65), presence of children (persons aged below 18), presence of other adults, and work status of
household members (allowing to distinguish between households with zero, one, and two or more
workers), in the second.
59.
Because of the emphasis, in this paper, on changes
in income inequality and poverty, an effort
was made to improve data comparability over time for individual countries. To that effect, in cases of
major changes in national survey methods (e.g. Sweden and Canada in 1995)
56
, data have been collected
on both the âoldâ and ânewâ bases, so as to allow chain-linking of various indicators. The use of a common
questionnaire and methodology (e.g. in terms of equivalence of scales, income components, and poverty
thresholds) also allows better comparisons of levels
of the different variables across countries. However,
the national data used in this paper differ in certain aspects that escape âstandardisationâ across countries,
and this may affect cross-country comparisons. Detailed characteristics of country data are shown in
Annex Table 1. Some of the main features that may affect comparisons across countries and time include
the following:
âą
Differences in the definition of households
. For most countries, households refer to a group of
people living in the same house and having common provisions for essential items. In some
countries, however, children above a given age are considered as a separate household unit (e.g.
Sweden until the mid-1990s), even if living in their parentsâ home. More restrictive definitions of
âhouseholdâ will tend to reduce household size and equivalised income (and increase poverty
rates) relative to other countries.
âą
Period over which income is assessed
. Data generally refer to income in the year preceding the
interview, with the exception of Austria (date relate to monthly income) and Spain (data relate to
quarterly income). Even for countries where annual income data are shown, however, income
may be assessed over a shorter reference period and then converted to an âannual equivalentâ
(e.g., data refer to weekly income in the United Kingdom, while in Australia the reference period
differs across income sources). Countries using shorter reference periods to measure income will
generally display higher poverty rates because of the greater volatility of weekly income and
higher probability of recording periods of âtemporaryâ income shortfalls (i.e. poverty rates are
likely to be higher than would have been found had income been recorded on an annual basis).
55
This implies that, to keep economic well-being unchanged, household income needs to increase by 41%
when a second member joins the household, by a further 32% for a third one, and by 26% for the fourth.
56
In the case of Canada, the
Survey of Labour and Income Dynamics
is used in place of the
Survey of
Consumer Finances
starting in 1995. In the case of Sweden, the definition of households changed in 1995.
DELSA/ELSA/WD/SEM(2005)1
53
âą
Gross and net income.
All income components are generally reported on a âgrossâ basis, i.e.
before deduction of direct and payroll taxes (social security contributions) paid by individuals
and households. Exceptions are Austria, the Czech Republic (for 2000), Greece, Hungary,
Mexico, Poland, Spain and Turkey, where income components are recorded on a ânetâ basis (i.e.
information on taxes paid is not available). Even for countries where taxes are separately
identified, however, there are differences in the way these are computed, with some countries
relying on data as reported by respondents (e.g. Japan, France), others on values from tax records
(e.g. Belgium, Denmark), and others still on values âimputedâ though microsimulation models
applied to individual records (e.g. Italy, New Zealand, Portugal). In the latter case, cross-country
differences in the details and assumptions used (e.g. with respect to tax evasion) may affect the
comparability of results.
57
âą
Income components.
The data generally distinguish between earnings (broken down into the
earnings of the household head, of the spouse and of other household member)
58
; self-
employment income; capital income (rents, dividends and interest); and current transfers received
by households.
59
Capital income is generally limited to income paid in cash (however, in the case
of Denmark, Germany and Turkey, imputed rents of home-owners are included). Current
transfers refer to cash transfers paid by government to individuals and households. Because of the
exclusion of in-kind transfers, changes in the nature of government support (e.g. from provision
of social housing at subsidised rates to housing benefits paid in cash) may distort results. Private
transfers are generally included with capital incomes, with a few exceptions
60
. In some cases (e.g.
the United States), microsimulation models have been used to impute values of some cash
benefits (Earned Income Tax Credit, food stamps and housing benefits) that are not recorded in
surveys.
âą
Recording of private pensions.
There are large differences across countries in terms of the nature
and institutional arrangements governing private pensions. These differences relate both to their
mandatory or voluntary character, and to the nature of the agencies that are responsible for their
management and administration (i.e. in some cases, they may be part of the social security
administration, while in others they may be fully private). Also, private pensions are sometimes
not separately identified in the household surveys of some countries. Because of these
differences, private pensions that are substantially similar may be recorded differently across
countries: as part of âcapital income" in most countries, or as part of "public transfersâ in Austria,
the Czech Republic, Germany (prior to 2001)
61
, Hungary, Italy and Mexico (in these countries,
however, private pensions are very small). No attempt has been made to correct for these
discrepancies in classifications.
57
For example, because of the complexities of the German tax system, only standard deductions are
considered by the German micro-simulation model used to generate the data presented in this paper.
58
This breakdown of earnings, however, is not available in the case of Hungary, Norway and a few other
countries.
59
Negative income components are generally bottom coded to zero.
60
In Sweden, for instance, part of alimonies are included in current government transfers as, for a number of
families, there is a public intermediary between the parents.
61
In Germany, private pensions are included in "capital income" only in 2001; for previous years, when
private pensions were not separately identified in the survey, they are included in "public transfers".

ANNEX 2. POVERTY THRESHOLDS USED IN THE ANALYSIS
60.
The thresholds used in this paper to measure relative poverty are based on percentages (50% and
60%) of the median equivalised disposable income of all individuals, where household disposable income
is equivalised using the square root of household size. These thresholds, for the latest available year, are
shown in Annex Table 2. For example, for the United States, median equivalised disposable income of all
individuals in 2000 is USD 23,954 per year (in current prices), and the poverty threshold (at 50% of the
median) is USD 11,977 (second column). To ease interpretation, thresholds can also be expressed on a
ânon-equivalisedâ basis (i.e. with no adjustment for household size). A person living alone (whose
âequivalisedâ and ânon-equivalisedâ income are identical) will be considered as (relative) âpoorâ when his
disposable income is less than USD 11,977 (column 3), while a household composed of two adults and one
child will be counted as poor when its total household income is less than USD 20,745 (column 5). It
should be noted, however, that these ânon-equivalisedâ thresholds differ from those that would be obtained
by applying a different elasticity for household size to micro data (
e.g.
if all individuals had been ranked by
their household income, with no adjustment for household size, median income and poverty thresholds
would have differed from those shown below). Annex Table 2 also shows (in the last column) values of the
poverty thresholds for a singe adult as a percentage of the take-home pay of an average production worker;
in most OECD countries, poverty thresholds for a single person are in a range between 40% and 60% of
the take-home pay of an average production worker, although they are higher (Hungary) and lower
(Australia, Japan, Mexico, New Zealand, Poland and Turkey) in some countries.

relative poverty at half of median disposable income

that from "early to mid-90s". OECD25 average includes all countries for which data are available for mid-90s and 2000. OECD20 average includes all countries for which data were
available for mid-80s, mid-90s and 2000 and excludes Belgium, the Czech Republic, Hungary, Poland, Portugal, Spain and Switzerland. OECD18 average excludes, in addition, Mexico
and Turkey. OECD25 uses data for reunified Germany, OECD20 and OECD18 use data for old LĂ€nder only.
