PREA requires the Attorney General to submit, no later than Jun 30th of each year, a report that lists institutions in the sample and ranks them according to the incidence of prison rape. BJS has developed a multiple measure, multiple-mode data collection strategy that fully implements PREA requirements. The National Survey of Youth in Custody (NSYC) provides facility-level estimates of youth reporting sexual victimization in juvenile facilities. Rates of youth-on-youth sexual assault in female only juvenile facilities (5.3 percent) were more than three times greater than those in male-only facilities. Youth-on-youth sexual assault was most prevalent (4.5 percent) when facilities had a high concentration of youth with histories of sexual abuse ( 24 percent or more of such youth). Staff sexual misconduct was most prevalent in detention centers (7.4 percent) and training/long-term secure facilities (7.3 percent). The National Inmate Survey (NIS) collects data on the prevalence and incidence of sexual assault in adult prisons and local jails as reported by inmates. Past NIS collections show that prisoners have higher rates of sexual victimization than jail inmates. In the 2017 report,4.0 percent of State and Federal prisoners reported having experienced some type of sexual victimization perpetrated by another inmate (2.0 percent) or staff (2.4 percent). In comparison, 3.2 percent of jail inmates reported some type of sexual victimization perpetrated by another inmate (1.6 percent) or staff (1.8 percent). A listing of previously released reports is provided.
