Child marriage is most common within the world’s poorest countries. This is because in families with limited resources, child marriage is often seen as a way provide for their daughter’s future. It allows parents to reduce expenses by having one less person to feed, clothe, and educate (https://www.icrw.org/files/images/Child-Marriage-Fact-Sheet-Poverty.pdf).
Most child brides have almost no choice but to perform unpaid work in the house due to their lack of education. This traps girls and their families in a cycle of poverty.
However, by not marrying early and staying school, girls are likely to be both healthier and wealthier – and thus ending the cycle of poverty.
