Survey Description

The National Inmate Survey (NIS) is part of the Bureau of Justice Statistics (BJS) National Prison Rape Statistics Program, which collects reported sexual violence from administrative records and allegations of sexual victimization directly from victims through surveys of inmates in prisons and jails and surveys of youth held in juvenile correctional facilities. The NIS gathers mandated data on the incidence and prevalence of sexual assault in correctional facilities. The survey was conducted in three iterations from 2007 to 2012. Currently, no information pertaining to further administration of the NIS beyond 2012 is available.

Survey Sample Population

In the third administration year (NIS-3), the survey was conducted in 233 state and federal prisons, 358 jails, and 15 special confinement facilities operated by Immigration and Customs Enforcement (ICE), the U.S. Military, and correctional authorities in Indian country. The survey was administered to 92,449 inmates age 18 or older, including 38,251 inmates in state and federal prisons, 52,926 in jails, 573 in ICE facilities, 539 in military facilities, and 160 in Indian country jails. The survey was also administered to juveniles ages 16 to 17 held in adult prisons and jails.

Survey Mode

The NIS was conducted in three iterations from 2007 to 2012 known as NIS-1 (conducted 2007), NIS-2 (conducted 2008-09), and NIS-3 (conducted 2011-12). The interviews, which averaged 35 minutes in length, used computer-assisted personal interviewing (CAPI) and audio computer-assisted self-interviewing (ACASI) data collection methods. For approximately the first two minutes, survey interviewers conducted a personal interview using CAPI to obtain background information and date of admission to the facility. For the remainder of the interview, respondents interacted with a computer-administered questionnaire using a touchscreen and synchronized audio instructions delivered via headphones. Respondents completed the ACASI portion of the interview in private, with the interviewer either leaving the room or moving away from the computer.

Response Rates

Approximately 90% of the participating inmates (54,137) received the sexual victimization survey. More information on the number of participating inmates in each jail facility can be viewed in the appendix section table 5 of the ‘Sexual Victimization in Prisons and Jails Reported by Inmates, 2011-12’ press release.

Additional Background

The National Prison Rape Statistics Program requires a statistical review and analysis of NIS data under the Prison Rape Elimination Act of 2003 (PREA; P.L. 108- 79). Due to the sensitive nature of violent victimization and potential reluctance to report sexual assault, estimates of the prevalence of such acts do not rely on a single measure. Thus, BJS developed the National Prison Rape Statistics Program (NPRSP), a series designed to collect multiple measures on the incidence and prevalence of sexual assault. No data collection existed that could be used to fully respond to the requirements in PREA. BJS, with the aid of correctional practitioners, researchers, and special interest groups, developed, tested, and revised each collection prior to full national implementation. For these reasons, the data collections were rolled out consecutively rather than concurrently.
