The CJRP facility inclusion criteria were as follows: residential facilities in operation on the census reference date (generally the fourth Wednesday in October), public or private (or tribal since 1999) operation, and intended for juvenile offenders (although some hold adults as well). Specifically excluded were: nonresidential facilities, detention centers operated as part of adult jails, facilities exclusively for drug abusers or dependent/neglected youth, foster homes, and federal correctional facilities (e.g., Immigration and Naturalization Service, Bureau of Indian Affairs, United States Marshalls, or Bureau of Prisons). The CJRP inclusion criteria for individual-level data were as follows: youth under age 21, assigned a bed in a residential facility at the end of the day on the census reference day, charged with an offense or court-adjudicated for an offense, and in residential placement because of that offense.
The JRFC inclusion criteria for facilities in the census were: the facility must house persons under the age of 21 who were charged with or adjudicated for an offense, and were present in the facility on the reference date because of that offense. JRFC did not capture data on adult prisons or jails, nor did it include facilities that were used exclusively for mental health or substance abuse treatment or for dependent children.
Juveniles held in a juvenile residential facility in the United States for an offense on the census reference date in 1997, 1999, 2001, 2003, 2006, 2007, and 2010 and the facilities that held them between 1997 and 2010.
United States Bureau of the Census questionnaires
Using the number of in-scope facilities (i.e., able to hold juvenile offenders over night) as a base, the CJRP facility response rate was 96 percent in 1997, 100 percent in 1999, 99 percent in 2001, 100 percent in 2003, 100 percent in 2006, 100 percent in 2007, and 93 percent in 2010. The response rates for the JRFC are not available.
