How many counties does Michigan have?
Michigan has 83 counties covering 56,539 square miles and roughly 10,077,716 residents. The state was admitted to the Union in 1837 as the 26th state, and the current county boundaries reflect more than a century of administrative subdivision.
The largest county by land area is Marquette County at 1,808 square miles, home to about 68,828 residents. The most populous is Wayne County with approximately 1,767,712 residents — a density of about 2,888 people per square mile.
At the other end of the scale, Keweenaw County has only about 1,807 residents.
Michigan’s capital is Lansing, while the largest city is Detroit — a common pattern in the United States, where many states placed their capitals in smaller, more central towns rather than their largest commercial hubs.
