This article reviews six federally funded in-kind public assistance pr
ograms that are intended to mitigate the effects of poverty on low-inc
ome children by providing access to basic human necessities such as fo
od, housing, education, and health care. The evidence suggests that, w
hile each program can be improved, these programs do achieve their bas
ic objectives. In general, food stamps, the Special Supplemental Food
Program for Women, Infants, and Children (WIC), and school nutrition p
rograms are successful at providing food assistance to low-income chil
dren, starting with the prenatal period and continuing through the sch
ool years. The Food Stamp Program provides food assistance nationwide
to all households solely on the basis of financial need and is central
to the food assistance safety net for low-income children. The WIC pr
ogram has helped reduce the prevalence of iron-deficiency anemia in in
fants and children and has increased intakes of certain targeted nutri
ents for program participants. The school nutrition programs provide f
ree or low-cost meals that satisfy the dietary goals of lunches and br
eakfasts to most school-age children. The Medicaid program has extende
d health insurance coverage to millions of low-income children. Howeve
r, many children remain uninsured, and children enrolled in Medicaid d
o not have the same access to medical care as privately insured childr
en. Relatively little is known about the effects of Medicaid on childr
en's health status. For Head Start, empirical evidence suggests that p
articipating children show enhanced cognitive, social, and physical de
velopment in the short term. Studies of the longer-term impacts of Hea
d Start are inconclusive. Although housing assistance improves housing
quality and reduces housing costs for recipients, there is a large un
met need for acceptable, affordable housing among poor families. Impor
tant gaps remain in our knowledge of the effects of these programs on
the well-being of children. Questions regarding a program's effects ov
er time on health and developmental outcomes particularly need more st
udy.
