Uniform Crime Reporting Program Data [United States]: Offenses Known and Clearances by Arrest, 1960

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, FBI）便编制统一犯罪报告（Uniform Crime Reports, UCR），用于定期开展全国范围的已报案犯罪情况评估——这类评估成果是刑事司法体系内其他渠道无法获取的。执法机构可直接提交报告，或通过所属州的报告项目间接报送相关数据。每年需上报四类汇总数据文件：(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集文件包含月度统计数据，涵盖犯罪指数（Crime Index）类犯罪的报案总量，以及通过逮捕或其他方式结案的犯罪数量。该统计范围覆盖从受害者、发现违规行为的警务人员或其他渠道获取的全部指数类犯罪报案记录（纵火案件除外）。
