This project explores the dynamics of child care subsidy use among low-income families and examines the factors associated with stable (long-term) subsidy use and positive economic outcomes at the exit of subsidy receipt. In addition, this research provides estimates of the extent to which child care subsidy receipt is associated with changes in mothers' earnings and how these relationships differ (or not) across racial/ethnic subgroups. The results are expected to provide needed information regarding long-term patterns of child care subsidy receipt in Wisconsin and the extent to which subsidies contribute to self-sufficiency for low-income working families. Sample: Families that applied for child care subsidies in Wisconsin in 2000; Measures: Wisconsin administrative data.
