Caveats

  • A prisoner is counted under whichever state's or the federal government's jurisdiction is legally responsible for them, regardless of the facility where they are actually held, including another jurisdiction's prison, a privately operated facility, or a local jail.
  • Figures are a snapshot on December 31 of the year, not a count of admissions, releases, or an average population over the year.
  • Each annual edition of this report covers two years. Where a later edition gives a different figure than an earlier edition for a year both cover, the later edition's figure is kept, since the Bureau of Justice Statistics revises earlier counts.
  • The District of Columbia does not appear in this dataset. DC felony sentencing has been the Federal Bureau of Prisons' responsibility since December 31, 2001, so no separate DC jurisdiction total is published.
  • A small number of state and year combinations have no published figure and are left out here rather than estimated.
  • For the nation, this figure is the state total and the federal total combined, not a sum limited to state prison systems.
  • This is the rate the Bureau of Justice Statistics itself publishes, using the U.S. Census Bureau's population estimate for January 1 of the following year as the denominator; it is not calculated here.
