The National Institute of Corrections depends on publicly available information to provide the information on this page.

The statistics for budgets, employee positions, and state prison facilities data comes from state departments of corrections (DOCs), other state reports and state agencies. If data is missing for a state, then we were unable to find that information.

The data on prison population and incarcerate rate come from the Prisoner in 2018 report released by the Bureau of Justice Statistics (BJS). That report includes the count of prisoners in the unified systems of Alaska, Connecticut, Delaware, Hawaii, Rhode Island, and Vermont.

Violent and property crime rates are provided by the Federal Bureau of Investigations.

The number of counties per state comes from the United States Census Bureau.

Current jail population by state is unavailable. The most recent census was conducted by BJS in 2014.
