Sample size is 7,853 in all regressions. Weights are given by equation (8). Standard errors, reported in parentheses errors adjust for clustering at the county level. All regressions include 20 cohort dummies, 20 county dummies, 21 year of birth of child dummies, interactions between the treatment dummy and the county-specific junior high school enrollment rate in 1966 and between the treatment dummy and the fraction of workers in agriculture in 1967, and interactions between the county and year of birth of child dummies. All means except for the postneonatal mortality rate are weighted by the cell-specific number of births. The mean of the latter variable is weighted by the cell-specific number of infants who survive the neonatal period. For low birthweight, the mean is the percentage of light births. For neonatal and infant mortality, the means are deaths per thousand live births. For postneonatal mortality, the mean is deaths per thousand survivors of the neonatal period.
