This dataset contains the most recent data available and is updated anytime Detroit Police Department (DPD) sends official crime records contributing to the Michigan Incident Crime Reporting (MICR) or the National Incident Based Reporting (IBR) systems (reflected by the IBR Date field). It should be noted that some incidents involve the commission of multiple offenses, such as a domestic assault where property was also vandalized. Accordingly, the data describe all offenses associated with all reported incidents.
In order to protect the privacy of crime victims, addresses are shown at the block level only and the geographic coordinates (longitude and latitude) have been randomly offset by up to 180 feet along the street segment.
DPD works with the Department of Innovation and Technology (DoIT) to de-identify location information for both 911 calls and reported crimes to protect victim and caller information. These data are based upon preliminary information supplied to the Police Department by the reporting parties and are subject to verification. The Detroit Police Department does not guarantee (either expressed or implied) the accuracy, completeness, timeliness, or correct sequencing of the information and the information should not be used for comparison purposes over time. The Detroit Police Department will not be responsible for any error or omission, or for the use of, or the results obtained from the use of this information.
Note that DPD launched a new system to collect crime reports on that date, and certain fields of information may not be appropriate to compare between the two systems. Both systems were used to enter reports on December 6, 2016, so neither dataset is inclusive alone of all reports entered on that day.
