The Prison Rape Elimination Act of 2003 (P.L. 108-79) (PREA) requires the Bureau of Justice Statistics (BJS) to carry out a comprehensive statistical review and analysis of the incidents and effects of prison rape for each calendar year. This report fulfills the requirement under Sec. 4(c)(2)(B)(ii) of the Act to provide a list of juvenile correctional facilities according to the prevalence of sexual victimization. It presents findings from the first National Survey of Youth in Custody (NSYC), representing approximately 26,550 adjudicated youth held nationwide in state operated and large locally or privately operated juvenile facilities. Overall, 91% of youth in these facilities were male; 9% were female. Tables are appended. (Contains 18 tables.)
