The 2019 Census of Jails (COJ) is part of a series of data collections that study the nation's local jails. The 2019 COJ collected data necessary for producing estimates on local jail populations, including one-day custody counts by sex, race and Hispanic origin, conviction status, and severity of offense (felony and misdemeanor); counts of non-U.S. citizens by conviction status; juvenile counts; holds for state and federal authorities; admissions and releases; and average daily population by sex. It also collected data on facility information, including rated and design capacity, staffing, and opioid testing and treatment programs. The COJ is the only collection that enumerates local jails in the United States and provides inmate counts at the jail facility level. It provides the sampling frame for the Survey of Inmates in Local Jails (SILJ) and the Annual Survey of Jails (ASJ).

    Methodology

    The Census of Jails (COJ) collects jurisdiction-level information on inmates, facility characteristics, staff, programs, and costs of incarceration. It excludes temporary holding facilities and state-operated facilities in Connecticut, Delaware, Hawaii, Rhode Island, and Vermont. The 2006 COJ was limited by significant item nonresponse.
