- Indicator id: `imprisonment_rate`
- Unit: per 100,000 people
- Note: Counts only prisoners sentenced to more than 1 year, so it differs from the prison population rate used for other countries (prison_population_rate), which counts everyone held in prison, pre-trial detainees included. Prisoners are counted by the jurisdiction with legal authority over them, wherever they are held, on December 31. The national figure adds the federal system to the states. Local jails are not included, except in Alaska, Connecticut, Delaware, Hawaii, Rhode Island and Vermont, which run one combined prison and jail system. Felons sentenced in the District of Columbia have been the responsibility of the Federal Bureau of Prisons since 2001, so the District has values only up to 2000.
