“We produce annual estimates of age-specific fertility rates (ASFR) for girls aged 10-14 and 15-19 from 1950 to 2023 for the world, regions and 201 countries and territories…
Between 1990 and 2023, global ASFR for girls aged 10-14 decreased by 76%, from 4.5 to 1.1 births per 1000, while ASFR for girls aged 15-19 fell by 48%, from 74.7 to 39.0 births per 1000. In 2023, births to mothers aged 10-14 years were estimated at 347 thousand, and for those aged 15-19 years at 12.2 million. The number of births among adolescents aged 15-19 in sub-Saharan Africa increased during 1990-2023 due to population growth and slower fertility declines.”
