Sub-Saharan Africa not only has the highest number of of child marriage in the world but the practice also costs the continent a fortune in lost earnings and human capital.
More than three million (or one third of) girls in sub-Saharan Africa married before their 18th birthday in 2017, according to Educating Girls and Ending Child Marriage: A Priority for Africa, a new report by World Bank. Child brides, according to the report, are much more likely to drop out of school and complete fewer years of education besides being more likely to have children at a young age, which affects their health as well as the education and health of their children.

While many African countries have achieved gender parity in primary education, the report notes that girls lag behind boys at the secondary level. While seven out of 10 girls complete primary education across sub-Saharan Africa, only four out of 10 complete lower secondary school.
On average, women who have a secondary education are more likely to work and they earn twice as much as those with no education. Estimates for 12 countries—which account for half of the African continent’s population—suggest that through its impact on girls’ education, child marriage is costing these countries $63 billion in lost earnings and human capital wealth.
“Primary education for girls is simply not sufficient. Girls reap the biggest benefits of education when they are able to complete secondary school, but we know that girls very often don’t stay in school if they marry early,” says Quentin Wodon, Lead Economist at the World Bank and principal author of the report.

Child marriage also leads to high fertility rates and population growth, the report notes. If child marriage were ended today, lower population growth would lead to higher standards of living, especially for the poorest.
The report confirms that keeping girls in school is one of the best ways to avoid child marriage. Each year of secondary education reduces the likelihood of marrying as a child before the age of 18 by five percentage points or more.
The report also documents the impact of child marriage and girls’ education on more than three dozen other development outcomes. For example, child marriage leads to higher risk of intimate partner violence, and lower decision-making in the household. Child marriage also affects the well-being of the children of young mothers, including higher risks of mortality and stunting (malnutrition) for children below the age of five.
