Note: The dependent variable is one if the individual is enrolled in Grade 1 or higher and zero otherwise. All models are population weighted and clustered at the state of residence level. Heteroskedastic-consistent standard errors are in parentheses. Bold coefficients are significant at the 5 percent level. Columns 1, 3, 5, and 7 include indicators for the existence of publicly funded kindergarten, sex, race, state of residence, and census-division-specific year cohorts. Columns 2, 4, 6, and 8 further include birth quarter indicators and interactions between state of residence and birth quarter and year and birth quarter. The sample includes six-year-olds from the 1960, 1970, and 1980 U.S. Censuses. An asterisk in Column 2, 4, 6, or 8 indicates that youngest plus the specified interaction effect (i.e., β1 + β2, β1 + β3, or β1 + β4) is nonzero at the 10 percent level.
