Internal migration and county population dynamics for michigan counties

During the latter half of the 2000-2010 decade the State of Michigan experienced a large and growing net outmigration of citizens. This research uses Internal Revenue Service migra-tion data to examine recent trends in county-to-county net internal migration from one county to another within Michigan as well as migration from Michigan counties to counties in other states. The IRS data indicate that all but six Michigan's 83 counties experienced net outmigra-tion outside Michigan in 2007-2008, including 14 counties with net outmigration to other states in 2007-2008 at a rate greater than one percent of their populations. The slowdown in general economic activity from 2007-2010, likely was responsible for a portion of the movement of persons away from Michigan and has changed the economic landscape of Michigan's coun-ties; however, further research is necessary to determine whether or not Michigan may have entered into a long-term pattern of chronic high outmigration.
