Despite a steady decline in child marriage in the last decade, multiple crises including conflict, climate shocks, and the ongoing fallout from COVID-19 are threatening to reverse hard-earned gains, according to this new analysis by UNICEF. Worldwide, an estimated 640 million girls and women alive today were married in childhood, or 12 million girls per year, according to the latest global estimate included in the analysis. The share of young women who married in childhood has declined from 21 per cent to 19 per cent since the last estimates were released five years ago. However, in spite of this progress, global reductions would have to be 20 times faster to meet the Sustainable Development Goal of ending child marriage by 2030.
