Total Adult Community Supervision Population in the US

"From yearend 2011 to yearend 2021, the total adult community supervision population fell 22%, from 4,818,300 to 3,745,000 (table 1). Most of this decrease was due to a decline of 25% (1 million) in the number of adults on probation. The community supervision population has declined each year since 2007 and, at yearend 2021, was at its lowest level since 1994.2

"The probation population declined for the fourteenth consecutive year in 2021, falling below 3 million for the first time since 1994. Between 2011 and 2019, the U.S. parole population remained relatively stable, then decreased 8.6% from yearend 2019 to yearend 2021.

"The probation population had an annual decrease of 2.3% in 2021, about a quarter of the 8.3% annual decline observed during the COVID-19 pandemic in 2020 (figure 2). In 2021, the parole population had its largest recorded annual decrease (down 7.1%) since 1980, when BJS started collecting probation and parole information on a yearly basis (figure 3)."
