Estimated Population of Michigan Counties and Regions: 2000-2009
The estimates available on this page were developed by the U.S. Census Bureau through the Federal-State Cooperative for Population Estimates. In March of each year, the U.S. Census Bureau releases new estimates of county population for the year just completed as well as revised estimates for prior years. These estimates can then be aggregated to produce totals for metropolitan areas, planning areas, and other regions that consist of groups of counties.
