How many counties does Kansas have?
Kansas has 105 counties covering 81,760 square miles and roughly 2,947,026 residents. The state was admitted to the Union in 1861 as the 34th state, and the current county boundaries reflect more than a century of administrative subdivision.
The largest county by land area is Butler County at 1,430 square miles, home to about 68,780 residents. The most populous is Johnson County with approximately 611,320 residents — a density of about 1,292 people per square mile.
At the other end of the scale, Greeley County has only about 1,302 residents.
Kansas’s capital is Topeka, while the largest city is Wichita — a common pattern in the United States, where many states placed their capitals in smaller, more central towns rather than their largest commercial hubs.
