Nearly 650 million women alive today were married as children, and the figure is still enormous. Each year at least 12 million girls are married before their 18th birthday, even as global prevalence has fallen from 25% to 21% over the last decade. In the poorest households and conflict settings the pattern sharpens fast, with rates up to 50% higher than average, raising the question of what changes and what stays the same when policies and protection do not reach everyone.
