FBI violent crime data for Washtenaw County in 2019, the most recent data pool available, shows some departments have been more successful than others in solving violent crimes. Washtenaw County has a population of roughly 367,000, according to the U.S. Census Bureau, with 10 police forces in operation. While some of the county’s smaller police departments have the highest clearance rates, the rate does not necessarily reflect the quality of police work, as each department provides police services for its various jurisdictions which vary greatly in population when compared to the number of sworn officers on staff and resources available.
