Finding GIS Data

Public safety data like locations of crimes and traffic accidents as well as calls for service are available from the City of Milwaukee and the State of Wisconsin. If you're looking outside of these areas, check your local municipal, county, or state government for resources.

Because public safety data such as crime and accident data frequently includes personally identifiable information (PII), this information is often redacted and anonymized. Location information may be approximate in order to further protect privacy.

Furthermore, individual police departments, sheriff departments, and other law enforcement agencies report this information in various ways, via various platforms, and with various levels of detail.
