Child poverty, labor markets and public policies across industrialized countries Bruce Bradbury Social Policy Research Centre University of New South Wales Sydney Australia Markus Jäntti Åbo Akademi University Department of Economics and Statistics Turku Finland March 2005 Draft Not for citation Abstract This paper examine trends in relative and “real” child poverty across selected industrialized countries using data from the Luxembourg Income Study. The relative importance of markets and the public sector in determining the living conditions of the worst off children is examined by relating average income of the poorest fifth of children to the overall median and the decomposing this into the part that is rewarded by markets and the part that stems from net social transfers. The results suggest that the composition of relative average income in the lowest quintile group of children appears to vary quite substantially but at a broadly similar relative living standard within a country across time. Regressing these components on unemployment rates, working-age social expenditures and a businesscycle indicator suggests this variation is at least in part accounted for by these variables. 1 Introduction To what extent are the living standards of the worst off children in modern industrialised nations determined by markets and the public sector? The traditional view, based on a comparison of poverty measured before benefits are received and taxes paid with that after the welfare state has intervened, suggests that poverty rates are low in the countries that devote more public transfers to low income families. Our research, based on comparing average market income and average net public transfers across countries for the poorest fifth of children in a number of OECD countries, however, suggests that countries devote surprisingly similar amounts of cash to the worst-off children. Variation in the market incomes is an important factor in accounting for differences in child well-being, at least measured in terms of the average family income of the poorest fifth of children, whether in relative terms or in Purchasing Power Parity (PPP) adjusted international dollars. This finding suggests that, if we want to understand why children in some countries are better off than in others, we should examine both social transfers and why the market income of the parents of the worst-off children varies across countries (Bradbury and Jäntti, 1999). The United Nations Children’s Fund (UNICEF) has published several research reports on child poverty in rich countries.1 The latest UNICEF Report Card (UNICEF, 2000), based in large part on Chen and Corak (2005) and Corak et al. (2005), extensively review the trends in relative and “backdrop” child poverty in advanced countries. Among the countries they study, Norway, the United Kingdom and the United States experienced declines in child poverty, Canada and Finland had little change and most others, including Luxembourg, Mexico, Germany, Italy, Hungary and the Netherlands saw increases in child poverty. In studying factors that underlie the observed changes, Chen and Corak (2005) separate between demographic factors, labour markets and public sector effects. Demographic factors turn out to be less important than markets and the public sector. Both UNICEF and Chen and Corak (2005) are careful to stress interactions between between labour markets and the public sector. This is particularly true of the 1 These include Cornia and Danziger (1997), Bradbury et al. (2001), Bradbury and Jäntti (1999), UNICEF (2000), and, most recently, UNICEF (2005) which is based on several papers, including Corak et al. (2005) and Chen and Corak (2005).

Indeed, a detailed decomposition analysis suggest that the effect of the change in government transfers in the US would have been to increase poverty. It seems that the US in the 1990s the composition of government transfer changed in such a way as to at least facilitate a greater reliance on labour markets for children’s economic well-being. The purpose of this paper is to re-examine trends in children’s living standard using data from the Luxembourg Income Study (LIS), a collection of internationally comparable micro-data on income distribution and selected labour market data from 29 countries spanning the early 1970s to currently the year 2000. We offer a perspective that complements that used in UNICEF (2000), based on earlier work for UNICEF (Bradbury and Jäntti, 1999, 2001). In particular, we study the average relative disposable income of the poorest fifth of children in each country, a measure that is easily decomposable into a part that stems from markets and a part that is the difference between direct taxes paid and income transfers received. This measure allows us to examine simultaneously the well-being of the worst-off children and the composition of their income packages, as well as how these change over time. The paper is structures as follows. In Section 2 we present the definitions and methods we use for measuring children’s living standards. Section 3 shows the trends in both poverty and our alternative measure of children’s well-being, the average income of the poorest fifth relative to the overall median. We turn in section 4 how the composition of this measure of child well-being varies across countries, time and different household types. This section also presents some descriptive regressions that relate the composition of children’s average income to labour market conditions, the business cycle and social expenditures. A final section offers some concluding comments. 2 Data and methods We measure children’s living standards using data from the Luxembourg Income Study (LIS).2 . LIS covers 29 industrialised countries, most of which with information for several years, containing altogether 133 datasets. The objective is look at the general patterns of variation in child poverty outcomes 2 The Luxembourg Income Study comprises a database of household income survey information, adjusted to be as comparable as possible. For more information see http://www.lisproject.org/. 2 across the industrialised world. We here only examine OECD countries (although the LIS does not include some OECD countries, such as Greece, Japan, New Zealand and Portugal, which are therefore not included in our analysis). We examine child poverty as measured by the low-income status of their households. This does not capture all aspects of child poverty or more broadly child deprivation, nor is it intended to do so.3 While all areas of the deprivation of children are highly relevant, there are good reasons to study the income position of children in particular, including the fact that money income is a central vehicle for generating economic well-being in modern industrialised countries and that income data are readily available.4 Three major decisions that must be made in any poverty study concern the measure of resources, the choice of sharing unit (e.g. within nuclear families or within households) and the equivalence scale (the needs of different types of sharing units). There is a very large literature that addresses these issues (see e.g. Gottschalk and Smeeding, 1997; Jenkins and Lambert, 1993; Jäntti and Danziger, 2000) . Our choices on these matters are fairly standard, limited in part by the structure of the data available to us. Our measure of resources is annual5 disposable income. This includes market incomes and government cash transfers, and deducts income taxes and compulsory social insurance contributions. Whilst this is not a comprehensive indicator of the resources available to the families of children (e.g. it excludes non-cash services) it remains the best available indicator of cross-national variations in living standards. These issues of the appropriate resource measure (and the role of non-cash benefits in particular) are discussed in more detail in Bradbury and Jäntti (1999). For a recent treatise on the measurement of income, see Expert Group on Household Income Statistics (The Canberra Group) (2001). We assume resources are shared within households and define every person in the household to have the same poverty status. This definition is the one that is most commonly available across our countries. The exception to this is Sweden, where the source data before the last wave of LIS is limited to tax units, corresponding to nuclear families of parents and their dependent children. Prior to 2000, 3 The approach of this paper rests on work done for the UNICEF (Bradbury and Jäntti, 1999, 2000, 2001). See also UNICEF (2000), available at http://www.unicef-icdc.org/research/ESP/CIIC1.html. 4 See Chen and Corak (2005) for a recent discussion on measuring living standards and poverty. 5 Except in the UK, where current income is used. 3 Swedish adult children and lone parents living with their parents are treated as separate units.6 Children are defined to be persons who are 17 years old or younger. Their economic resources are measured by allocating to each child the income per equivalent adult, calculated by dividing household cash disposable income by a scale that is close to the so-called “old” OECD scale (see Bradbury and Jäntti, 1999). Our scale, used by Jenkins and Cowell (1994) and also recommended for use by the US National Science Foundation Poverty Commission National Research Council (1995), associates children with lower needs than adults and then uses a power of the number of adult equivalents to standardise for economies of scale. Bradbury and Jäntti (1999) examine this issue at some length. This difference is not very important for ranking countries by level of child poverty. The literature on poverty measurement has typically used two types of poverty threshold: absolute and relative poverty lines. Absolute , or more properly, fixed real price poverty lines, are thresholds which permit people living in specified family types to purchase the same bundle of goods and services in different countries or times. Families that fall below the common consumption threshold are therefore considered to be poor. Relative poverty lines, on the other hand, are more closely related to concepts of social exclusion. These poverty lines are typically defined with reference to a measure of typical consumption levels (e.g. half median income). Arguably, a focus on child poverty also calls for a somewhat different relative poverty line. If children are excluded from social participation, the most important form of this may be exclusion from the lifestyle typically enjoyed by other children. Similarly if the exclusion of children arises via the exclusion of their parents, it will most often be other parents that they compare themselves with rather than, say, the elderly. This suggests the use of a poverty line defined with reference to the average living standard of children in the society. The use of the median as anchor-point can be loosely justified in terms of a social exclusion, but has also a practical basis. In household surveys, because data collection errors at the two extremes of the income distribution are likely to be more frequent, the median is a more robust measure of central tendency than the mean. 6 There are other differences within countries across time in LIS. The original datasets that underlie the “lissified” compa- rable data may have changed and in one case (Germany, see below) the area to which it refers has changed. We do not make allowances for changes in data sources within countries, but essentially treat all country datasets as being representative for the countries’ population. 4 Though the comparison of real living standards across countries requires the use of strong assumptions, many would argue that it is a more important concept than that of relative poverty. To focus only on the relative measures would be, for example, to discount entirely the poverty alleviation benefits of income increases that were spread (proportionately) evenly across the population. Both the relative and real measures provide important insights into the way the living conditions of the most disadvantaged children vary across countries. Relative poverty is measured by estimating the proportion of children whose economic resources are less than one half of the median of adjusted disposable income in their country in the year of the survey. We also measure poverty defined in an internationally comparable metric, Purchasing Power Parity-adjusted (PPP) international 2000 dollars, relative to the US official poverty line for a family of four in 2000.7 The key method that is used in theis paper is based on the simple decomposition of the equivalised disposable income of a household that disposable income ≡ market income + net public transfers. Since this holds for all households it also holds for the average income of the poorest fifth. Average disposable income in the poorest fifth of children is closely related to the relative poverty rate if we relate that average to median income, and to a internationally fixed real poverty line if we measure disposable income in terms of PPP-adjusted international dollars. Using this decomposition, we strive to account for how the private/public mix, measured in terms of this decomposition for the poorest fifth of children, lines up across countries and changes within countries across time. We have somewhat modified the standard LIS income variables for the analyses where we decompose disposable income in the poorest fifth into market income and net social transfers. In particular, we depart from the usual practise of either truncating or censoring disposable income at zero and leaving its constituent parts intact. Rather, we censor each of the following components at zero: earnings (head, spouse, other members), self-employment income, property income, other private income, social insurance income, means-tested transfers. We then add all market-based income components together to 7 Chen and Corak (2005) discuss an intermediate possibility, that of a “backstop” poverty line, which keeps the poverty line within a country fixed a few years at a time. We have not implemented such a line in this paper. 5 form market income, sum transfers from which we subtract taxes to form net social transfers and then define disposable income to be the sum of those. This is, obviously, coherent only for those datasets for which gross incomes are available. In our analysis we therefore focus on those countries and datasets that make available not only net incomes (i.e., income components from which taxes paid have been subtracted) but the actual gross values along with direct taxes. We often refer to LIS waves, which range from “Historical data” (year prior to 1978), to waves 1 through 5 (ending in 1982, 1987, 1992, 1997 and 2002, respectively). Wave 1 is thus roughly equivalent to “around 1980”, wave 2 around 1985, wave 3 around 1990, wave 4 around 1995 and the final wave 5 around 2000. Information on the datasets that underlie the LIS data can be obtained from the LIS website at http://www.lisproject.org/techdoc.htm. 3 Trends in children’s living standards [Figure 1 about here.] We start by examining long-run trends in relative child poverty, shown in Figure 1. These numbers, derived using the LIS definition of disposable income, show a fairly familiar ordering of countries. By the end of the 20th century the US has the highest poverty rate, followed by the United Kingdom, Canada, Ireland. Poland and Hungary have the highest poverty rates among transition countries. Belgium, Germany, the Netherlands and France all have poverty rates close to 10 percent, while the Nordic countries have rates around 5 percent. The sharp rise in US child poverty turned into a small and later accelerating decline in the 1990s. The UK trends seem more uncertain, but at least the sharp increase in the 1970s and 1980s appears not to have continued. Canadian child poverty rates have hovered above 15 percent for most of the time period covered by LIS. The Northern European countries, on the other hand, have experienced increasing child poverty rates during the years covered.8 [Figure 2 about here.] 8 For Germany, however, the year prior to 1994 include only former West Germany, while the former East Germany is included from 1994 onwards, which should account for a substantial part of the increase in poverty in the early 1990s. 6 We show for selected countries the proportion of children with income less than the US poverty line, as measured in international PPP adjusted dollars, along with the relative child poverty rate. These two rates appear to converge in most cases by the end of the 1990s (except, ironically, in the US where they diverge!). By the end of the 1990s, those countries that had low relative poverty rates also had low “real” poverty rates. [Figure 3 about here.] Before we proceed any further, we wish to address a couple of questions regarding the focus on relative child poverty. First, is a focus on children rather than all persons motivated? Second, does examining relative poverty tell something that general inequality does not? Third, is the focus on relative poverty misleading, or at least different from focusing on real living standards? To examine the first of these questions, we have plotted in Figure 3 on the horizontal axis overall relative poverty and on the vertical relative child poverty in each of the five LIS waves (along with the least squares regression line in each wave). While the agreement between these two indicators of poverty is quite good, there are some variations across the two measures. Moreover, the relationship appears to vary from year to year. For instance, Sweden had in the historical wave of LIS a low level of child poverty, but a relatively high level of overall poverty. Soon (by wave 1) Sweden’s overall poverty rate became, along with its child poverty rates, quite low. Thus, while closely related, child and overall poverty can and do change in distinct patterns across countries and time. [Figure 4 about here.] Our second question is if relative child poverty only measures relative inequality. In a technical sense this is not the case – the share of persons below on half of the median focuses on only part of the distribution, while relative inequality is measured on the whole range of incomes – but there is, again, a close but not perfect correspondence between the two. Perhaps most importantly, the increase in inequality among the Nordic countries in the 1990s seems not to have been associated with an increase in child poverty. Moreover, child poverty rates seem to have varied between 5 and 25 percent in all of the countries and time periods covered, while the range covered by the Gini coefficient has varied much more across time. 7 [Figure 5 about here.] Our third question concerns the focus on relative rather than “real” poverty. Whether one should study relative poverty or not is an open question, to say the least. In our view, the study of relative poverty and the study of poverty with respect to the same real standard of living across countries both have their merits. It is interesting, however, to examine how countries line up by these two criteria. [Figure 6 about here.] This paper is motivated by the mix of market incomes and (net) public transfers. We next turn to examine this mix using our decomposition of disposable income into market income and net social transfers. Before doing so, however, it seems prudent to examine the extent to which our analysis captures the ordering of countries with respect to disposable income poverty. We measure the living standards of the worst-off children using the average income of the lowest fifth of children ordered by the level of adjusted household disposable income. Our measure of relative living standard further relates this average to the overall median of adjusted household disposable income. The scatterplot of this measure of children’s living standards against relative child poverty is shown in Figure 6. It is useful to remember that an increase in the average income of the lowest fifth is associated with higher living standards, whereas of course the reverse is true for poverty. The poorest fifth of children have around 20 percent of the income of the median person in the US, a number that varies surprisingly little across time. In the UK and Canada, this ratio is around 30 percent, around fifty in the group of Northern European countries that come next and around 50 percent of the median in the Nordic countries. The ordering of countries by these two measures of children’s relative disadvantage are reasonably close, especially in the latest two waves of LIS. [Figure 7 about here.] On obvious determinant of children’s living standards is whether or not they live with both parents. It follows that variations across countries in the share of children living in lone-mother households is likely to affect the poverty ordering of countries. The impact of this is not very large (see Bradbury 8 and Jäntti, 1999), but it does suggest that examining living standards separately for different type of families is likely a good idea. In Figure 7 the scatterplot of poverty rates and lowest fifth average income relative to median disposable income in the latest wave of LIS for all households and for two-parent and lone-mother households, respectively.9 Two-parent poverty rates vary a lot less than those for lone mothers. Almost one half of US lonemother children are in poverty. The poverty rates for lone-mother children in the Nordic countries is also higher than for two-parent children, at around ten percent. With the exception of Germany, however, two-parent and lone-mother families follow reasonably closely that of all children. 4 Child poverty, labour markets and public policy [Figure 8 about here.] We now turn to examine the relative importance of markets and the public sector in determining children’s living standards. The standard way of examining the role of the public sector in reducing poverty is to compare poverty rates using incomes “before” social transfers have been added and (direct) taxes have been subtracted with poverty rates based on disposable income. Such a comparison is subject to many well-known objections – including the fact that, if no taxes were collected and no transfers paid, the distribution of market income would likely be quite different. Despite such shortcomings, such “first-order incidence” comparisons are widely used. We show in Figure 8 the “pre-post” scatterplot using data from wave 5 in LIS for different household types. The graphs are drawn on a log scale and include three rays, which separate between different degrees of poverty reduction achieved by the public sector – disposable income poverty being reduced by 25, 50 and 75 percent, respectively, counting clockwise from the vertical axis. For all and for twoparent children, the Nordic countries reduce market income poverty by around 75 percent. Most other 9 Recall that lone-mother families are defined as those with only a mother with children and no other adults present. A two-parent household likewise consists of two parents and their children but no other adults. Children in lone-father households and children in families with other adults – including possibly adult siblings – are all in the “other” category (but are of course included among all children. 9 countries reduce all children’s poverty by between 50 and 75 percent. The UK is remarkably more generous to lone-mother than to two-parent children, in that lone-mother child poverty rates, while high, are reduced with more than one half, while the reduction for two-parent children is around 30 percent. [Figure 9 about here.] We also show in Figure 9 the pre and post poverty rates in all available LIS datasets that contain more than just net income information. Lone-mother children, denoted by a “1” in this figure, always have a lot higher market income poverty rates than two-parent children. However, a clear pattern does emerge, in that in the US and Canada, those higher poverty rates are reduced with around 25 percent or less, which is around the same proportion by which two-parent children’s poverty is reduced. In the Nordic countries, higher pre poverty rates do not mean post rates are substantially higher. In the other European countries lone-mother rates are reduced by a greater proportion than two-parent children’s poverty rates. The UK, interestingly, seems to move from a North American regime toward a more Northern European one in this respect, as suggested by the fact that by the last wave of LIS, UK lonemother children’s poverty rates are reduced by more then 75 percent. [Figure 10 about here.] The analysis of the impact of the public sector on poverty above suffers, as noted, from a number of shortcomings. While it is not obvious this is, in fact, a shortcoming, these kinds of pre-post comparisons can not easily be subjected to decomposition analysis. This is the reason that we chose, above, to examine the average income of children in the lowest fifth in the income distribution among all children. Namely, as disposable income is identically equal to the sum of market income and net social transfers, this naturally also holds for average disposable income in the lowest quintile group. A scatterplot of countries by average market income and average net social transfers in the lowest fifth, relative to the overall median, neatly summarises several aspects of the living standards of the worst-off children (see Figure 10). First, since the sum of net transfers and market income is disposable income, the placement of a country along the iso-quants running north-west to south-east reveal the living standard of the worst-off children. The further to the north-east a country, the lower their poverty rate. 10 Second, we divide the figure by three rays, drawn from the origin, show points in the market incomenet transfer plane where 25, 50 and 75 percent, respectively, of the average disposable income of the poorest fifth originate from markets (vs. 75, 50 and 25 percent from net social transfers). The rays thus allow us to examine the “income package” of the worst-off children and, in particular, to what extent their incomes are being generated on labour markets or by public transfers. Figure 10 brings out the importance of both (labour) market income and of social transfers. The parents of Canadian (in 2000) and US children earn roughly 40 percent of the overall disposable median income from markets. Indeed, Finnish and Swedish children earn even more, around 45 percent of median income. The relative living standard of US children is a lot lower than than of Canadian and of Nordic children, however, because the US pays far less transfer incomes to these than these other countries do. On the other hand, the Dutch and Norwegian public transfers relative to the median are around the same magnitude as those in the US, but their market incomes are substantially higher. Finally, of the countries included in Figure 10, in the US, the Netherlands and Norway more three quarters of the income package of the lowest fifth of children consists of marker income. Poland, Germany, Canada in 2000, Sweden and Finland all have between 50 and 74 percent of children’s income stemming from markets whereas Canada in 1998 and the UK has most of these children’s income from the public sector. [Figure 11 about here.] [Figure 12 about here.] An analysis of the income package of the poorest fifth of children by household type reveals that the composition of the income package tends to vary quite substantially from year to year (see Figures 11 and 12). For instance, for the poorest fifth of US lone-mother children, 75 percent of their disposable income in Wave 1 stemmed from net social transfers. This proportion increased until in wave 5 (in the year 2000), then declined substantially to less than 50 percent. This variation in the composition of the income packages was achieved at a remarkably stable relative living standard. In other words, the initial increase and later decrease in net social transfers almost exactly corresponded to an equal but opposite change in market income. Put in yet another way, the increase in market income was for 11 these US children not associated with an increase in relative living standards, as it was matched by a decline in income transfers. Moreover, the relative poverty rate declined quite substantially in the US, while this measure suggests little change in the living standards of the worst-off US children. It may therefore be that the childrne who were moved out of poverty did not move very far, leading to know change in the average of the poorest fifth. Patterns in other countries, and also for two-parent children in the US, tends to be more varied, reflecting both changes in the relative well-being of the poorest fifth of children and the composition of their income packages. We see, for instance, an increase in the relative well-being of UK lone-mother children while the share of net scoail transfers also increased. In order to gauge the effect of factors that affect the well-being of the poorest fifth of children as well as the composition of their income package, we estimate simple regression equations for all children, lone-mother and two-parent children, respectively. Our explanatory variables consist of the overall unemployment rate, social expenditures on the working-age population as a percent of GDP, the log deviation of real GDP per capita from its long-run trends and the share of lone-mother children.10 We have two dependent variables, average market income of the poorest fifth relative to the overall median and average net social transfers relative to the overall median. We thus have two “seemingly unrelated” regression equations, albeit with the same explanatory variables. The error terms are allowed to be correlated, and we allow for random intercepts and time trends that vary across countries and income components. Formally, we estimate mii jt Xit 0 βmi, j εmi,i jt = + 0 Xit nsti jt βnst, j εnst,i jt 10 The (1) unemployment rate is taken from World Development Indicators 2004. Social expenditure data are drawn from OECD’s Social Expenditure Database, available on www.oecd.org. We experimented with distinguishing between workrelated transfers and non-work-related, but settled on using their sum instead. Work-related transfers consist of relative expenditures on active labour market programmes and unemployment-related expenditures. Non-work related transfers include survivors benefits, incapacity-related benefits, family-related benefits, housing benefits and “other” benefits. (These two consist of all social expenditure except that for health and old age.). Trends in real GDP per capita were estimated by regressing the log of real GDP per capita from the WDI on year. The residual of this regression in the LIS year measures business cycle position and is included among the regressors. The share of lone-mother children is estimated using LIS data using our definition of lone mothers (which includes only households with a mother and children but with not other adults present. 12 where i indexes countries, j is either all, lone-mother or two-parent children, X is the vector of explanatory variables and ε are error terms for which εk,i jt = ak,i j + bk,i j t + uk,i jt , k = mi, nst. (2) That is, we allow the relative market income or net social transfers of the poorest to vary by country and across time. This kind of regression equation is known by many names, such as “hierarchical model”, random coefficient model and linear mixed effect model. We use the function lme by Pinheiro and Bates (1999) in the statistical package R to estimate the β coefficients. [Table 1 about here.] The estimation results are reported in Table 1. The random time trends turn out to be statistically insignificant and are dropped in the reported regression equations. The coefficients were estimated in “interaction form”. The coefficients with no prefix for market income and the rows that start with “Inc.ComponentNST” should be added to the corresponding coefficient for market income to yield the coefficient on that variable for net social transfer. Thus, for instance, for all children (the first column), 0.532 is the intercept of market income whereas 0.016 = 0.532 − 0.516 is the intercept for net social transfers. The standard errors should be used with some caution, as no correction as been made for the fact that many of the variables consist of sample estimates with varying sampling variation. (Variation across the income components and within-country correlation are taken into account, however.) The coefficient estimates are of expected signs and are measured with reasonable precision (bearing in mind the caveat that the standard error estimates are suggestive at best). Having more children in lone-mother families decreases relative market income and increases relative net social transfers in all three cases examined. An increase in the overall unemployment rate also leads to a decrease in market income and an increase in net social transfers. Our measure of where in the business cycle LIS captures a country, the log deviation of GDP PPP per capita from its trend, is associated with higher relative market income and lower net social transfers. The most interesting finding concerns social expenditures (denoted by Transfers) which for all and two parent children is associated with higher market income and lower net social transfers, but has no 13 effect for lone-mother children. This may be driven by the fact that lone-mother children are relatively scarce, but is interesting nonetheless. 5 Concluding comments We have examined trends in relative poverty and an internationally comparable real income poverty standard. Our results show large declines in US poverty, substantively unchanged poverty in many countries and increases in some,mainly Northern European countries. Our alternative measure of children’s well-being, relating the average income of the poorest fifth to median disposable income, generates a similar ordering of countries but allows us to decompose their living standard by market income and net social transfers. Trends in this measure of children’s well-being suggest somewhat smaller changes in the living conditions of the worst-off children. In particular, neither the UK nor the United States display large declines in poverty according to this measure. Not unexpectedly, children in two-parent households are more likely to rely to a greater extent on market income than are children in lone-mother households. The estimates also reveal that the composition of poor children’s income package can vary substantially with little or not change in their living standards within a country. Our descriptive regressions show that unemployment, business cycles and lone parenthood affect the relative well-being of children as one expected.
