Federal Justice Statistics Program: Guideline Computations for Defendants Sentenced Under the Sentencing Reform Act, 2001

These data contain records of guideline computations and adjustments for each count of conviction for criminal defendants who were sentenced pursuant to provisions of the Sentencing Reform Act (SRA) of 1984 and reported to the United States Sentencing Commission (USSC) during fiscal year 2001. The data are one of two supplementary files that should be used in conjunction with the primary analysis file, which contains records for all defendants sentenced under the guidelines. These data can be linked to the primary analysis file using the unique identifier variable SEQ_NUM. The number of records for a defendant in the current data corresponds to the total number of guideline computations, which may or may not equal the total counts of conviction for that defendant, dependent upon the grouping rules of the particular guideline in question (see Section 3D1.2 of the guidelines manual). As an example, a defendant with five counts of drug trafficking will only have one guideline computation because each of the drug weights for each count are simply added together and only one calculation is necessary. However, if a defendant has five counts of bank robbery, he or she will have five separate guideline computations because bank robbery is considered to be a nongroupable offense. The data were obtained from the United States Sentencing Commission's Office of Policy Analysis' (OPA) Standardized Research Data File. 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.

本数据集包含2001财年依据1984年《量刑改革法案》（SRA）条款判刑、并上报至美国量刑委员会（USSC）的刑事被告每项定罪的量刑指南计算与调整记录。
本数据集是两份补充文件之一，需与主分析文件配合使用；主分析文件包含所有依据该指南判刑的被告记录。
通过唯一标识符变量SEQ_NUM，本数据集可关联至主分析文件。
某一被告在本数据集中的记录数量对应其量刑指南计算的总次数，该次数可能等于或不等于其定罪总项数，具体取决于相关特定指南的分组规则（详见指南手册第3D1.2节）。
例如，一名涉及五项贩毒定罪的被告仅需进行一次量刑指南计算，因每项定罪的毒品重量可直接累加，故仅需一次计算。
然而，若被告涉及五项银行抢劫定罪，则需进行五次独立的量刑指南计算，因银行抢劫被视为不可分组罪行。
本数据集源自美国量刑委员会政策分析办公室（OPA）的标准化研究数据文件。
本数据集是由华盛顿特区城市研究所（Urban Institute）与司法统计局联合设计的系列数据之一，其数据及文档由城市研究所编制。
