Survey of Inmates in State and Federal Correctional Facilities, 1997

Conducted by the Bureau of the Census, this survey provides nationally representative data on state prison inmates and sentenced federal inmates held in federally owned and operated facilities. Through personal interviews from June-October 1997, inmates in both state and federal prisons provided information about their current offense and sentence, criminal history, family background and personal characteristics, prior drug and alcohol use and treatment programs, gun possession and use, gang membership, and prison activities, programs, and services. Prior surveys of state prison inmates, called SURVEY OF INMATES OF STATE CORRECTIONAL FACILITIES, were conducted in 1974, 1979, 1986, and 1991 (see ICPSR 7811, 7856, 8711, and 6086). Sentenced federal prison inmates were first interviewed in 1991 (see SURVEY OF INMATES OF FEDERAL CORRECTIONAL FACILITIES, 1991 [ICPSR 6037]). The federal data are combined with the state data in this collection. Part 1, Numeric Data, consists of numerically-coded responses, while Part 2, Alphanumeric Data, contains free-field responses to "Specify, Other" questions in ASCII text form.

本调查由美国人口普查局（Bureau of the Census）主持，旨在提供具有全国代表性的数据，涵盖州立监狱在押人员以及关押在联邦自有并运营的监管设施内的已判刑联邦囚犯相关信息。1997年6月至10月期间，研究人员通过个人访谈的方式，向州立与联邦监狱的在押人员收集了如下信息：当前所涉犯罪及刑期、犯罪前科、家庭背景与个人特征、既往药物与酒精使用情况及治疗项目、枪支持有与使用行为、帮派成员身份，以及监狱内的活动、矫治项目与服务资源。

此前针对州立监狱在押人员的调查命名为《州矫正设施在押人员调查》（SURVEY OF INMATES OF STATE CORRECTIONAL FACILITIES），分别于1974、1979、1986及1991年开展，对应ICPSR编号分别为7811、7856、8711与6086。而已判刑联邦囚犯的首次调查则于1991年开展，即《1991年联邦矫正设施在押人员调查》（SURVEY OF INMATES OF FEDERAL CORRECTIONAL FACILITIES, 1991 [ICPSR 6037]）。

本数据集将联邦调查数据与州立调查数据进行合并整合。数据集分为两个部分：第一部分为数值数据（Numeric Data），包含经数值编码的问卷回复；第二部分为字母数字数据（Alphanumeric Data），以ASCII文本格式存储针对"指定其他项"类问题的自由字段回复。
