The FBI released Crime in the United States, 2013, which shows that the estimated number of violent crimes in 2013 decreased 4.4 percent when compared with 2012 figures, and the estimated number of property crimes decreased 4.1 percent. There were an estimated 1,163,146 violent crimes reported to law enforcement last year, along with an estimated 8,632,512 property crimes.

The crime statistics report, issued by the Bureau’s Uniform Crime Reporting (UCR) Program, contains voluntarily submitted data from 18,415 city, county, state, tribal, campus, and federal law enforcement agencies on specific crimes brought to their attention. They include the violent crimes of murder, rape, robbery, and aggravated assault, and the property crimes of burglary, larceny-theft, motor vehicle theft, and arson.

The primary goals of Crime in the United States, says the FBI, are to assess and monitor the nature and type of crime in the nation and to generate reliable information for use in law enforcement administration, operations, and management. The data has also been used by criminologists, sociologists, legislators, municipal planners, the media, and other students of criminal justice for research and planning purposes.

Beginning in 2013, the UCR Program began collecting rape data under a revised definition. However, not all law enforcement agencies have been able to convert their records management systems to reflect the new definition yet, so this year’s report includes data collected under the previous (or legacy) definition as well as the revised definition. Footnotes for tables in the report indicate which definition of rape is being used. For more information, read the report’s Rape Addendum.
