Welcome to the Michigan State Police Crime Facts Website. This website allows access to two different types of data collection systems that can be used to create queries and reports:
- The Uniform Crime Reporting (UCR) summary based data
- The Michigan Incident Crime Reporting (MICR) incident based data
This data has been collected from participating law enforcement agencies throughout the state.
The difference between the collection of incident data and the traditional summary data is the degree of detail in reporting. Under the summary UCR program, only the most serious offense was reported, along with Arson and only on eight crimes: Murder, Forcible Rape, Robbery, Aggravated Assault, Burglary, Larceny, Motor Vehicle Theft, and Arson.
The MICR system collects crime data concerning 61 different data elements for 95 file classes. Each MICR incident may contain up to six different record types: Administrative, Offense, Offender, Victim, Arrest and Property. Because of the differences between the UCR summary data and the MICR incident data, any cross-comparisons would provide inaccurate results in trend analysis.
In addition, this website allows users to view the annual Crime in Michigan report dating back to 1997. 2007 was the first year that Michigan published the annual report using exclusively incident based data. Prior to this, conversion back to the FBI Summary system was required for the annual Crime in Michigan report. Also in 2007, the MICR program was converted to an Oracle server from a Mainframe server. Due to this conversion, a searchable data set could not be produced for 2007 data. Therefore, 2007 data is only available in the Annual Publications section of this website.
