Consistencies and contradictions: Revisiting the relationship between women's education and infant mortality from a...

The connection between women's education and infant mortality is one of the most consistent and powerful relationships established in public health. A large body of cross-national research highlights the benefits of women's access to education, especially for improving population health in developing countries. However, most of this literature assumes the relationship is uniform across cases. In this study, we revisit the education-health link using a distributional approach. To do so, we conduct a series of unconditional quantile regression analyses that estimate the impact of female secondary school enrollment on infant mortality rates across 153 countries from 1970 to 2016. This technique allows for the possibility that the relationship between education and health may vary across the distribution of mortality. Indeed, results show that the education advantage is distribution-specific. We find that the expected benefits of women's education are limited to the middle of the distribution where infant mortality rates range from about 11 to 55 deaths per 1000 live births. However, we find no significant effect where mortality is comparatively low or high. Both consistent with and contradictory to prior research, these findings provide a more nuanced picture of how women's access to education relates to global health inequalities.
