This study presents a detailed look at the immigration and internal mi
gration dynamics of child poverty for US States based on the 1990 US c
ensus. It assesses the impact of two policy-relevant factors on the mi
gration of poor children across States: (1) the role of high immigrati
on levels as a potential ''push'' for native-born and longer-term resi
dent poor children whose parents may be reacting to the economic compe
tition or social costs in high immigration States; and (2) the role of
State AFDC benefits as a potential ''pull'' for poor children who mig
rate with their parents to States with higher benefit levels. The resu
lts make plain that the interstate migration patterns of poverty child
ren differ from those of nonpoverty children, especially among whites
and blacks. Female-headed households show different inter-state migrat
ion patterns than those in married-couple households. However, a multi
variate analysis which includes standard state-level economic attribut
es provides more support for an ''immigration push'' than for a ''welf
are magnet pull'' in affecting the inter-state migration of poor child
ren. The findings also show a demographic displacement of poor childre
n occurring in high immigration States where the net out-migration of
poor children is more than compensated by larger numbers of new immigr
ant children in poor families with different demographic attributes. B
ecause of these migration dynamics, the demographic profile of the chi
ld poverty population will differ across States, suggesting the need f
or different strategies toward reducing child poverty at the State lev
el.
