Uniform Crime Reporting Program Data [United States]: Offenses Known and Clearances by Arrest, 1962

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，联邦调查局（Federal Bureau of Investigation）便启动统一犯罪报告（Uniform Crime Reports，UCR）的编制工作，以定期开展全国范围内的已上报犯罪情况评估——这类评估信息在刑事司法系统的其他渠道中无法获取。执法机构可直接报送报告，或通过其州级报告项目完成上报。
每年会以四类文件汇总上报摘要数据：
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（LEOKA）数据（Police Employee (LEOKA) Data）
其中，已知犯罪与逮捕结案情况数据集包含月度统计数据，涵盖已上报的犯罪指数（Crime Index）罪行数量，以及通过逮捕或其他方式结案的罪行数量。该统计范围覆盖从受害者、发现违规行为的警员或其他渠道获取的所有指数类犯罪报告（纵火罪除外）。
