Conditional means of mother’s years of schooling by child’s birth month and areas.

Notes: Conditional means are predicted by an OLS regression model of mother’s years of schooling on child’s birth months (effective coding) for urban and rural samples separately. Dummy variables of child’s birth year and provinces are controlled in the models. A solid triangle or circle marker represents that the value significantly differs from the grand mean at a significance level of 0.01
