Notes: Each column is from a separate regression. In panel A, mothers residing in Austin, Dallas, Houston, and San Antonio are omitted. In panel B, mothers with risk factors are omitted. In Panel C the WIC interaction indicates that there was a clinic operating in the zip code at some point during the mother’s pregnancy. See notes under Tables 1 and 4 for information about the sample, the storms and hurricanes, and the estimation methods and controls. For each outcome, births by mothers who have at most one child with non-missing data for that outcome are omitted.
