Federal Justice Statistics Program: Offenders Admitted to Prison, 1999

The data contain records of sentenced offenders committed to the custody of the Bureau of Prisons (BOP) during fiscal year 1999. The data include commitments of United States District Court, violators of conditions of release (e.g., parole, probation, or supervised release violators), offenders convicted in other courts (e.g., military or District of Columbia courts), and persons admitted to prison as material witnesses or for purposes of treatment, examination, or transfer to another authority. These data include variables that describe the offender, such as age, race, citizenship, as well as variables that describe the sentences and expected prison terms. The data file contains original variables from the Bureau of Prisons' SENTRY database, as well as "SAF" variables that denote subsets of the data. These SAF variables are related to statistics reported in the Compendium of Federal Justice Statistics, Tables 7.9-7.16. Variables containing identifying information (e.g., name, Social Security Number) were replaced with blanks, and the day portions of date fields were also sanitized in order to protect the identities of individuals. These data are part of a series designed by the Urban Institute (Washington, DC) and the Bureau of Justice Statistics. Data and documentation were prepared by the Urban Institute.

本数据集收录了1999财年期间被交由美国监狱管理局（Bureau of Prisons, BOP）羁押的已判刑罪犯的相关记录。数据集涵盖的收押对象包括美国联邦地区法院作出判决的罪犯、违反监管条件（如假释、缓刑或监督释放）人员、由其他法院（如军事法院或哥伦比亚特区法院）定罪的罪犯，以及以关键证人身份入狱或因接受治疗、检查、移交至其他监管机构而收押的人员。本数据集包含描述罪犯个体特征的变量（如年龄、种族、公民身份），以及与刑期和预期监禁时长相关的变量。数据文件包含来自美国监狱管理局SENTRY数据库的原始变量，以及用于标识数据集子集的“SAF”变量。此类SAF变量与《联邦司法统计汇编》中表7.9至7.16所报告的统计数据相关。为保护个人身份信息，所有包含标识性信息（如姓名、社会保险号）的变量均已替换为空值，同时日期字段中的日份信息也已进行脱敏处理。本数据集是城市研究所（华盛顿哥伦比亚特区）与美国司法统计局联合开发的系列数据之一，数据集及配套文档均由城市研究所编制完成。
