On January 1, 2008, more than 1 in 100 adults in the United States were in prison or jail. Total U.S. incarceration peaked in 2008. According to a November 2017 report by the
World Prison Brief around 212,000 of the 714,000 female prisoners worldwide (women and girls) are incarcerated in the United States. In the United States in 2016, women made up 9.8% of the incarcerated population in adult prisons and jails. Comparing English-speaking developed countries; the overall incarceration rate in the U.S. was 531 per 100,000 population of all ages in 2021,
England and Wales was 146 per 100,000 in 2023, and
Australia was 158 per 100,000 in 2022. Comparing other developed countries, the rate of
Spain was 122 per 100,000 in 2020,
France was 90 per 100,000 in 2020,
Germany was 69 per 100,000 in 2020,
Norway was 49 per 100,000 in 2020,
Netherlands was 63 per 100,000 in 2018, and
Japan was 38 per 100,000 in 2019. The

apartheid." == Correctional supervision by state ==
