This scoping review of the evidence base on child marriage from 2000-2019 covers 386 articles that a) focus on child or early marriage or informal unions in lower and middle income countries; b) provide new research insights based on a specified methodology; 3) and are published in English in either peer-reviewed or grey literature. The findings are arranged around 1) prevalence of child marriage, 2) its determinants, correlates and context, 3) its consequences, and 4) interventions to address child marriage.
The review indicates that the evidence base on child marriage in the last 20 years has been robust and varied, providing important insights on prevalence and measurement, determinants, correlates and context, consequences, and interventions.
