The term ‘child marriage’ refers to formal marriages and informal unions in which a girl or boy under age 18 lives with a partner as if married. In an informal union, a couple lacks a formal civil or religious ceremony. Our graphic is based on United Nations information. The main sources are national census and household surveys, including the Multiple Indicator Cluster Surveys (MICS) and Demographic and Health Surveys (DHS). Surveys are subject to sampling and measurement error. We used the U.N. child marriage and population figures to approximate how many women in each country were married before 15 and before 18.
