National Archive of Criminal Justice Data
This dataset is maintained and distributed by the National Archive of Criminal Justice Data (NACJD), the criminal justice archive within ICPSR. NACJD is primarily sponsored by three agencies within the U.S. Department of Justice: the Bureau of Justice Statistics, the National Institute of Justice, and the Office of Juvenile Justice and Delinquency Prevention.
Uniform Crime Reporting Program Data [United States]: Offenses Known and Clearances by Arrest, 2007 (ICPSR 25101)
Alternate Title: UCR Offenses Known, 2007
Principal Investigator(s): United States Department of Justice. Federal Bureau of Investigation
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.
These data are freely available.

- United States Department of Justice. Office of Justice Programs. Bureau of Justice Statistics
Scope of Study
Geographic Coverage: United States
Date of Collection:
Universe: Index crimes reported by law enforcement agencies in the United States.
Data Types: aggregate data
Data Collection Notes:
Starting with the year 1998, each of the four types of UCR summary data archived by ICPSR is released as a separate study under its own study number. Offenses Known and Clearances by Arrest data for the years 1975-1997 can be found in UNIFORM CRIME REPORTING PROGRAM DATA: [UNITED STATES]: 1975-1997 (ICPSR 9028).
Mode of Data Collection: self-enumerated questionnaire
Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Performed consistency checks.
- Checked for undocumented or out-of-range codes.
