Offenses Known
to Law Enforcement

Download Printable Document

The FBI’s Uniform Crime Reporting (UCR) Program collects offenses known to law enforcement for violent crime and property crime, as well as data regarding clearances of these offenses. In addition, the FBI collects data about these offenses (e.g., time of day of burglaries). These expanded offense data also include trends in both crime volume and crime rate per 100,000 inhabitants. Finally, the UCR Program collects expanded homicide data via the Supplementary Homicide Report (SHR). SHR data include information about homicide victims and offenders, weapons used, the circumstances surrounding the offenses, as well as information about justifiable homicides.

Violent crime

Violent crime is composed of four offenses: Murder and nonnegligent manslaughter, forcible rape, robbery, and aggravated assault. Violent crimes are defined in the UCR Program as those offenses which involve force or threat of force.

Property crime

Property crime includes the offenses of burglary, larceny-theft, motor vehicle theft, and arson. The object of the theft-type offenses is the taking of money or property, but there is no force or threat of force against the victims.

Clearances

Within the UCR Program, law enforcement agencies can clear, or “close,” offenses in one of two ways: by arrest or by exceptional means. Agencies may administratively close a case, but this does not necessarily mean that the agency can clear the offense for UCR purposes.

Expanded offense data

The FBI collects the number of offenses for the crimes of murder and nonnegligent manslaughter, forcible rape, robbery, aggravated assault, burglary, larceny-theft, motor vehicle theft, and arson through the UCR Program. In addition to the number of offenses known to the police, the FBI also collects additional data about these offenses, such as the locations of robberies, time of day of burglaries, and other analyses about the offenses. These expanded data also include trends (2-, 5-, and 10-year comparisons) in both crime volume and crime rate per 100,000 inhabitants.

Expanded homicide data

The UCR Program’s SHR data, presented in the expanded homicide data section of this Web publication, provide information regarding the age, sex, and race of the murder victim and the offender; the type of weapon used in the murder; the relationship of the victim to the offender; and the circumstance surrounding the incident. These data also include information about justifiable homicides.
