Complete enumerations of jail facilities, as well as data on private jails, staffing, and inmate programs, are collected in the Census of Jails, conducted periodically. Summary data from the 2006 Census of Jail Facilities are forthcoming; the most recent data available is from the Census of Jails, 1999. Basic capacity information is collected in the Annual Survey of Jails, and some jail facility characteristics are also gathered periodically within the Survey of Inmates in Local Jails (SILJ).
