This study seeks to explain macrolevel drivers of adolescent fertility rate using a panel data set derived from 17 Latin American countries over a period of 16 years (1997–2012). While many studies of adolescent fertility have focused on individual-level explanations, this study explores whether adolescent fertility rate is correlated to country-level determinants, specifically legislation adoption that guarantees access to school-based sexuality education, emergency contraception, and abortion. After controlling for other country-level factors, we find that countries that have adopted legislation on school-based sexuality education and those with legal access to abortion (under one or more restrictions) have lower adolescent fertility rates.
