Notes: See Table 4 for included covariates. Each panel is a separate regression. All regressions include controls for maternal characteristics and time trends and county fixed effects. Columns (1)- (3) use permit date to define “treatment” and the coefficient reported is the interaction between an indicator for whether the permit was within 2.5 km from the mother’s residence and whether the birth occurred after (post) the permit date. Columns (4)-(6) use a random date to define post birth.
