Before presenting these results, it is useful to note that children’s living standard is difficult to capture for the reason that the statistics on income are provided at the household level w'ith no information on how resources and expenses are actually shared across family members. In this perspective, income quantiles are defined as values of household income w'hich divides the frequency distribution into equal groups, each containing the same fraction of the total population of children. Panel A, the round marker shows that children in couple families at all points of the income distribution saw a relative increase in both market and disposable income.
