Data Collection: Survey of Inmates in Local Jails (SILJ)
Status: Active
Frequency: 1972, 1978, 1983, 1989, 1996, and 2002
Latest data available: 2002

Conducted periodically, the survey provides information on individual characteristics of jail inmates, current offenses and detention status, characteristics of victims, criminal histories, family background, gun possession and use, prior drug and alcohol use and treatment, medical and mental health history and treatment, vocational programs and other services provided while in jails, as well as other personal characteristics. Data are collected through personal interviews with a nationally representative sample of inmates in local jails. The survey utilized a two-stage sample design in which jails were selected in the first stage and inmates within local jails were selected in the second stage.

Methodology

The sample for the 2002 survey was selected from the universe of all jails in the U.S., which were enumerated in the 1999 Census of Jails.The sample design was a stratified two-stage selection, in which jails were selected in the first stage and inmates to be interviewed were selected in the second stage. In the first sampling stage, six separate strata were formed based on the size of the male, female, and juveniles populations in each jail. In strata one and two, all jails were selected to ensure jails with large numbers of males, females or juveniles had a higher probability of selection than jails with a small inmate population. The weighting procedure consisted of a base weight for each inmate, and four adjustment factors that produced the final weight for the survey. Data were collected through face-to-face interviews with jail inmates using computer-assisted personal interviewing.

Changes Over Time

Periodically, changes are made to the questionnaires to improve measurement and to collect new information on evolving issues in criminal justice, and topics of  greatest interest to the field and data users. Recent modifications include enhanced questions on medical and mental health histories of inmates. In 2002, the sample design was modified to ensure a representative sample of juveniles being held in local jails.
