Notes: Each coefficient in each panel is from a separate regression. The sample is limited to singleton sibling births with mothers that reside in Texas over 2005–2009. Births with missing gestation length or gestation less than 26 weeks are omitted. All regressions include birth year and birth month fixed effects. The regressions in Panel B also include ZIP code fixed effects. Robust standard errors are clustered on the ZIP code level.
