Uniform Crime Reporting Program Data: Arrests by Age, Sex, and Race, United States, 2021

These data provide information on the number of arrests reported to the Federal Bureau of Investigation's (FBI) Uniform Crime Reporting (UCR) Program each month by police agencies in the United States. Although not as well known as the "Crimes Known to the Police" data drawn from the Uniform Crime Report's Return A form, the arrest reports by age, sex, and race provide valuable data on 43 offenses including violent, drug, gambling, and larceny crimes. The data received by ICPSR were structured as a hierarchical file containing (per reporting police agency) an agency header record, and 1 to 12 monthly header reports, and 1 to 43 detail offense records containing the counts of arrests by age, sex, and race for a particular offense. ICPSR restructured the original data to a rectangular format.

本数据集收录了美国各警务机构每月向美国联邦调查局（Federal Bureau of Investigation, FBI）统一犯罪报告（Uniform Crime Reporting, UCR）项目上报的逮捕人数相关信息。尽管其知名度不及源自统一犯罪报告A类上报表单（Return A form）的“警方已知犯罪”数据集，但按年龄、性别与种族分类的逮捕报告仍涵盖了暴力犯罪、毒品犯罪、赌博犯罪及盗窃犯罪等共计43类犯罪的宝贵数据。ICPSR获取的原始数据采用层级文件结构：每个上报警务机构对应1条机构头记录、1至12条月度头报告，以及1至43条详细犯罪记录，每条详细记录均统计了某一特定犯罪按年龄、性别与种族划分的逮捕人数。ICPSR已将原始数据重构为矩形格式。
