Fertility · UN WPP 2024
One number decides whether a nation grows or vanishes.
The fertility rate is the average number of children per woman. Above 2.1, a population replaces itself. Below it, each generation is smaller than the last. Spin the globe or search your country to see where it sits.
Children per woman. Blue is below the 2.1 replacement line; orange is above. Gold marks the line.
Figures as reported by the United Nations (World Population Prospects 2024), including for territories the UN lists separately. Borders are shown de-facto; disputed boundaries appear dashed and imply no endorsement of any territorial claim.
