About this Topic

The Bureau of Justice Statistics (BJS) conducts the Census of Jails every 5 to 7 years to collect data on jail facilities, staffing, and inmate programs. Jail capacity information is also captured in the Annual Survey of Jails. Some jail facility characteristics are also gathered periodically in the Survey of Inmates in Local Jails (SILJ). See Jail Data Collections and Surveys for more information.
