The National Inmate Survey (NIS) is part of the BJS National Prison Rape Statistics
Program that gathers mandated data on the incidence of prevalence of sexual assault in
correctional facilities under the Prison Rape Elimination Act of 2003 (PREA; P.L. 108-
79). The Act requires a 10% sample of correctional facilities to be listed by
incidence of sexual assault, with a minimum of one prison and one jail facility in
each state. Data are collected directly from inmates in a private setting using audio
computer-assisted self interview (ACASI) technology with a touch-screen laptop and an
audio feed to maximize inmate confidentiality and minimize literacy issues. See
Methodology in reports for sampling and weighting information.

The Prison Rape Elimination Act of 2003 (PREA; P.L. 108-79) requires a 10% sample of correctional facilities to be listed by incidence of sexual assault, with a minimum of one prison and one jail facility in each state. See Methodology section in reports for sampling and weighting information, which varies by collection year. Inmates are randomized to either a survey on sexual victimization or an alternative survey on substance abuse and treatment (questions from which are also used to pad out time for respondents completing the victimization survey quickly).
