Federal Justice Statistics Program: Offenders in Prison at Year-End, 2008

The data contain records of sentenced offenders in the custody of the Bureau of Prisons (BOP) at year-end of fiscal year 2008. 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2008财年年底由美国联邦监狱管理局（Bureau of Prisons, BOP）监管的已判刑罪犯记录。数据集涵盖经美国地区法院收押的罪犯、违反监管条件者（如假释、缓刑或监督释放违规者）、其他法院（如军事法院或哥伦比亚特区法院）定罪的罪犯，以及作为关键证人、因接受治疗、检查或移交至其他监管机构而收押的人员。数据集包含描述罪犯个体的变量，如年龄、种族、公民身份，同时也涵盖与刑罚及预期监禁时长相关的变量。本数据集文件包含来自美国联邦监狱管理局SENTRY数据库的原始变量，以及"SAF"变量，此类变量用于标识数据子集。此类"SAF"变量与《联邦司法统计汇编》中表7.9至7.16所载的统计数据相关。为保护个人身份信息，所有包含标识性信息的变量（如姓名、社会保险号）均已替换为空值，日期字段中的日份部分也已完成脱敏处理。本数据集是城市研究所（华盛顿特区，DC）与美国司法统计局联合设计的系列数据之一，数据集及相关文档均由城市研究所编制。
