This project explores how parental employment and household structure shape low-income families' access to and use of (a) developmentally-beneficial childcare options and (b) childcare subsidies. The project includes three main studies (each a free-standing paper). In the first, changes over time in parental work schedules in single-mother and two-parent households are analyzed. The second enumerates the consequences of these parental work schedules for a range of childcare outcomes. The third paper investigates changes over time in household structure and their effects on the use of relative care for young children.
