Michigan county geography overview

Michigan has 83 counties, which places it 15th among the 50 state and District of Columbia maps in this atlas when ordered by number of county-level units. Their combined 56,612.4 square miles of land place the state 22nd by mapped land area.

The average county-level area is 682 square miles, while the median is 567.8 square miles. The median is often the better description of a typical unit because one or two very large areas can pull the average upward. The five largest units together account for about 12% of the state’s mapped land area.

Rankings use land area rather than total area. This avoids making coastal or lake counties appear larger solely because their boundaries include extensive water.

Alphabetical list of Michigan counties

The table is alphabetical, so it works as a name and FIPS-code reference rather than an area ranking. Every identifier begins with the Michigan state FIPS prefix 26. Land and water figures are rounded to one decimal place.

How to read and use this map

County lines are administrative boundaries, not postal routes. A mailing address can use a city name associated with a neighboring area, and ZIP codes can cross county lines. When you need to identify a county for an address, confirm it with an official geocoder or local government source.

For classroom or planning use, download a PDF from the controls above. Labelled exports use numbered callouts for crowded areas; numbered quiz maps match the alphabetical county list. SVG files keep the boundary lines sharp at larger paper sizes.

Interpreting the water figure: About 41% of the summed mapped area in this state is water. County water area can include coastal waters, bays, lakes, or rivers assigned by the Census boundary file; it is shown separately from land and should not be used to estimate developable land.
