Despite very different macroeconomic conditions, demographic structure
s and degrees of income inequality, favorable income changes among low
-income families with children were widespread and strikingly similar
across the eight countries in our study. In most European countries, t
he combination of modest inequality and extensive mobility among the p
oor enabled virtually all families to avoid relative income deprivatio
n at least occasionally. However, even substantial mobility among the
poor in the Unites States could not elevate the living standards of on
e in seven white and two in five black families to a level that was ha
lf that enjoyed by a typical American family.
