Notes: Each coefficient is from a separate regression. See notes under Tables 1 for information on the sample. All regressions include include time-varying controls for mother’s age, education, marital status, and child’s birth order, conception year and conception month, and an indicator for living within 30km of an area that was ever affected by a storm or hurricane over the time period. Robust standard errors are clustered on the mother.
