You can purchase this data using ProPublica’s Data Store.**The Uniform Crime Reports, comprised of six databases, includes crime information reported to the FBI by law enforcement agencies around the country. Most of the data consist of the “index” crimes: murder, nonnegligent manslaughter, forcible rape, robbery, aggravated assault, burglary, larceny-theft, motor-vehicle theft and arson. These crimes, with the exception of arson, were chosen in 1929 to serve as an index for gauging fluctuations in the overall volume and rate of crime. Arson was added by Congressional mandate in 1979.During the early planning of the program, it was recognized that the differences among criminal codes precluded a mere aggregation of state statistics to arrive at a national total. Further, because of the variances in punishment for the same offenses in different state codes, no distinction between felony and misdemeanor crimes was possible.

All databases in the Uniform Crime Reports, except the Supplemental Homicide Report (SHR), are arranged by police reporting agencies. Occurrences are presented as aggregates. The data is broken down by month. All the databases provide the region, state, county, city, metropolitan statistical area (MSA) and reporting agency identifier.

The data are available in either CSV or SQL format (the latter for MySQL users only).

Contact the database library if you are interested in a state slice, or a single database (such as the SHR).

  • Crimewise, OC ranks as peaceful area
    Statistically, speaking, from a crime standpoint, Orange County is a tide pool in a turbulent ocean. None of the county’s large cities ranks among the most crime-ridden communities in California. And crime rates elsewhere in the nation dwarf those in the county according to a Register analysis of the FBI’s Uniform Crime Report.
  • Crime Magnets
    This investigation used FBI Uniform Crime Report data to show that most of the crime in Tucson occurs in the North side of the city. The violence — which can be explained by a combination of poverty, prostitution, drug dealing and strip clubs — is so bad that many people choose to move away rather than work to change the situation. The findings contradict the perception that the predominately Hispanic South side of Tucson, where gang violence is prevalent, is the most dangerous area of the city.
