Coefficients presented are risk difference estimates from logistic regression models estimating associations between girl child marriage and secondary outcomes, with 95% CIs in parentheses, controlling for EA fixed-effects and primary education and clustering standard errors at sample cluster level. For each secondary outcome, only women belonging to clusters in which there is variation in the outcome are included. Girl child marriage is defined as marriage before age 18. All variables are self-reported by participants. Secondary education estimates restrict to women who completed at least primary education. Wealth index was based on principal component analysis of household ownership of 6 core items (type of toilet facility, source of drinking water, main floor material, main wall material, and main roof material). **p < 0.01, *p < 0.05
