Michigan Incident Crime Reporting

The MICR Unit is the State's Repository for Crime Data

The Michigan Uniform Crime Reporting (UCR) program was instituted in 1959. Law enforcement agencies voluntarily submitted their crime data to compile a uniform crime report. Per STATUTE, crime reporting came required with Public Act 319 of 1968. In 1982, the collection of incident-based data began, resulting in the Michigan Incident Crime Reporting program.

Testing: All agencies must go through the testing process when changing records management systems. Please click here for more information.
