In the United States since 1930, Uniform Crime Reports (UCR) have been tabulated annually by the FBI from crime data submitted by law enforcement agencies across the United States. This data is compiled at the city, county, and State levels into the Uniform crime reports (UCR). Violations of laws, which are derived from common law, are classified as Part I crimes in UCR data, and further categorized as violent and property crimes. Part I violent crimes include murder and criminal homicide (voluntary manslaughter), forcible rape, aggravated assault, and robbery, while Part I property crimes include burglary, arson, larceny/theft, and motor vehicle theft. All other crimes are classified as Part II crimes.
