National Inmate Survey (NIS) - Jails: Full Survey Respondents, [United States], 2007-2009

The purpose of the National Inmate Survey (NIS) is to gather data on inmates experiences within the state and federal judicial system. It is part of the Bureau of Justice Statistics Prison Rape Statistics Program (PREA). The primary data gathered as part of this program is on the prevalence of sexual assault and rape in correctional facilities. The Prison Rape Elimination Act of 2003 (PREA; P.L. 108-79) requires a 10 percent 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. A secondary purpose is to report on substance use, alcohol use, and substance abuse treatment prior to and during incarceration. The data in this particular study focuses solely on these secondary purposes. The data file does not contain data on sexual assault and rape during the respondent's stay in jail.

全国囚犯调查（National Inmate Survey, NIS）的核心宗旨为采集囚犯在州级与联邦司法体系内的服刑经历相关数据。该调查隶属于美国司法统计局（Bureau of Justice Statistics）监狱强奸统计项目（Prison Rape Statistics Program, PREA）。该项目的首要数据采集方向为惩教机构（correctional facilities）内性侵犯与强奸案件的发生率。2003年《监狱强奸消除法案》（Prison Rape Elimination Act, PREA；公法108-79）要求，需按性侵犯发生率抽取10%的惩教机构作为样本，且每个州至少需纳入1所监狱与1所看守所。该项目的次要目标为统计受访者在入狱前及监禁期间的物质使用、酒精摄入与物质滥用治疗情况。而本项特定研究的数据仅聚焦于上述次要目标，且其数据文件未包含受访者在看守所羁押期间遭受性侵犯与强奸的相关数据。
