AbstractThis research documents trends from 1970 through 1990 in the utilization and ameliorative effects of public assistance among poor children in nonmetropolitan (nonmetro) and metropolitan (metro) America. Results indicate that the families of nonmetro poor children rely more heavily on parental earnings and less so on public assistance when compared to their metro counterparts; that there was a sharp rise over the period in reliance on public assistance, especially among nonmetro children, and a corresponding decline in reliance on earnings; that the ability of public assistance to ameliorate child poverty is modest; and that while the ameliorative effects are always greater in metro than nonmetro areas, this disparity declined over the 1980s owing partially to improvement in nonmetro areas.
