Note. Standard errors are in parentheses. Models controlled for study-site dummies and the following baseline characteristics: follow-up length, prior earnings, prior earnings2, prior Aid to Families With Dependent Children receipt, prior years of employment, high school degree, teen parent, marital status, number of children, age of youngest child in family, and race.

a

Center-based child care includes care provided in a child care center, an extended day program at a school or community organization, and summer programs.

b

Home-based child care includes care provided by a relative, the mother's spouse or partner, or a nonrelative babysitter.

c

This category includes children 6–11 months in age at random assignment. There were insufficient numbers of children under 6 months to include in this analysis.

d

A significant chi-square statistic for the equality of coefficients indicates a rejection of the null hypothesis that all coefficients presented in the column are equal to one another.
