Uniform Crime Reporting

Ohio’s law enforcement agencies voluntarily report their crime statistics to the FBI’s Uniform Crime Reporting (UCR) Program through summary reporting or incident-based reporting.

  • Summary UCR Reporting provides basic aggregate statistics on the Part One crimes of murder, forcible rape, robbery, aggravated assault, burglary, larceny-theft, motor vehicle theft, and arson.
  • Incident-Based Reporting (Ohio incident-based reporting is called OIBRS) provides much more information on the details of the same crimes as the summary UCR Program, plus other crimes as well. OIBRS is a voluntary crime reporting program in which Ohio law enforcement agencies can submit crime statistics directly to the state and federal government in an automated format. This process has replaced the Summary UCR reporting process in many areas of the state.
