Emsi’s crime data comes from the FBI’s Uniform Crime Reporting Program and includes crime counts broken into two categories: violent and property crime.
- Violent crime: murder and nonnegligent manslaughter, rape, robbery, and aggravated assault.
- Property crime: offenses of burglary, larceny-theft, motor vehicle theft, and arson.
Local law enforcement agencies collect detailed incident level data regarding individual offenses and arrests and submit them to the National Incident-Based Reporting System using prescribed data elements and data values.
This data is often updated during the Q2 data run for the previous calendar year. Crime data is available at the county level for the United States.
