Girls in sub-Saharan Africa are disproportionately affected by child marriage; by 2050, half of the girls married during childhood will reside in Africa. The negative consequences of the practice are numerous and powerful, spanning health, welfare, development, and demographic domains. Yet, there is limited evidence on what works to delay child marriage in different cultural contexts and even less information on programmatic cost. This study develops and tests the most effective and minimum basic package approaches to delay marriage among older and younger adolescent girls, and estimates the cost and cost-effectiveness of implementing the different approaches, in Burkina Faso, Ethiopia, and Tanzania. In each study country, four approaches were tested: 1) community sensitization to address social norms, 2) provision of school supplies to encourage retention in school, 3) a conditional asset transfer to girls and their families, and 4) one study area that included all the approaches. The study aims to provide information on how best to design programs that are scalable and sustainable within poor settings, and which can provide support for the millions of girls in developing countries at risk of child marriage.
