Uniform Crime Reporting Program Data [United States]: Offenses Known and Clearances by Arrest, 1972

Since 1930, the Federal Bureau of Investigation has compiled the Uniform Crime Reports (UCR) to serve as periodic nationwide assessments of reported crimes not available elsewhere in the criminal justice system. Law enforcement agencies contribute reports either directly or through their state reporting programs. Each year, summary data are reported in four types of files: (1) Offenses Known and Clearances by Arrest, (2) Property Stolen and Recovered, (3) Supplementary Homicide Reports (SHR), and (4) Police Employee (LEOKA) Data. The Offenses Known and Clearances by Arrest data files include monthly data on the number of Crime Index offenses reported and the number of offenses cleared by arrest or other means. The counts include all reports of Index crimes (excluding arson) received from victims, officers who discovered infractions, or other sources.

自1930年起，美国联邦调查局（Federal Bureau of Investigation）便编制统一犯罪报告（Uniform Crime Reports, UCR），旨在提供刑事司法系统中其他渠道无法获取的、针对已报案犯罪的周期性全国性评估资料。执法机构可直接提交报告，或通过其所属州的报告报送体系间接上报。每年均以四类文件报送汇总数据：（1）已知犯罪与逮捕结案情况（Offenses Known and Clearances by Arrest）；（2）被盗与追回财物（Property Stolen and Recovered）；（3）补充杀人案报告（Supplementary Homicide Reports, SHR）；（4）警务人员数据（Police Employee (LEOKA) Data）。其中，已知犯罪与逮捕结案情况数据文件包含月度统计数据，涵盖已报案的犯罪指数罪案（Crime Index offenses）数量，以及通过逮捕或其他方式结案的罪案数量。该统计范围涵盖从受害者、发现违规行为的警务人员或其他渠道获取的所有索引罪案（Index crimes）报告（纵火案除外）。
