Although only about one in fve
children are in poverty each year, roughly one in three will
spend at least one year living in a poor household. Child pov-
erty is a signifcant concern to researchers and policymakers
because childhood poverty is linked to many undesirable
outcomes, including reduced academic attainment, higher
rates of nonmarital childbearing, and a greater likelihood of
health problems. Moreover, childhood poverty, especially
when it is deep and persistent, increases the chances that a
child will grow up to be poor as an adult, thereby giving rise
to the intergenerational transmission of economic disadvan-
tage.
