The U.S. incarceration rate fell in 2019 to its lowest level since 1995, according to recently published data from the Bureau of Justice Statistics (BJS), the statistical arm of the Department of Justice. Despite this decline, the United States incarcerates a larger share of its population than any other country for which data is available.
At the end of 2019, there were just under 2.1 million people behind bars in the U.S., including 1.43 million under the jurisdiction of federal and state prisons and roughly 735,000 in the custody of locally run jails. That amounts to a nationwide incarceration rate of 810 prison or jail inmates for every 100,000 adult residents ages 18 and older.
