Abstract
This paper examines how son preference and reproductive healthcare conditions interact to influence maternal morbidity and mortality. Using data on 2.5 million women across 44 developing countries between 1990 and 2018, we exploit cross-country variation in son preference intensity and healthcare conditions to document distinct patterns in maternal health. We show that in societies with strong son preference, women with first-born girls face higher incidence of moderate to severe anemia, a risk factor for maternal mortality. Moreover, these women exhibit lower survival into older ages where strong son preference coexists with poor maternal care. These patterns persist over time.
