Post-welfare reform has introduced a new set of policy questions around child care subsidy receipt. The present study addresses policy relevant questions that seek to better articulate the relationships between single mothers' decisions about work, child care and subsidy access. In addition, the study explores the relative importance of process and structural measures of child care quality in supporting children's development. Sample: Unmarried mothers with at least one child under age 13. Measures: Child Care Development Fund (CCDF) Program Records; National Survey of America's Families (NSAF); Early Childhood Longitudinal Study birth cohort (ECLS-B).
