How many counties does Wisconsin have?
Wisconsin has 72 counties covering 54,158 square miles and roughly 5,914,913 residents. The state was admitted to the Union in 1848 as the 30th state, and the current county boundaries reflect more than a century of administrative subdivision.
The largest county by land area is Marathon County at 1,545 square miles, home to about 131,688 residents. The most populous is Milwaukee County with approximately 926,469 residents — a density of about 3,844 people per square mile.
At the other end of the scale, Florence County has only about 3,470 residents.
Wisconsin’s capital is Madison, while the largest city is Milwaukee — a common pattern in the United States, where many states placed their capitals in smaller, more central towns rather than their largest commercial hubs.
