Counties in Indiana
Indiana consists of 92 counties. Indiana was organized into the United States since the Northwest Ordinance in 1787. As of the 2020 United States Census, the population of Indiana was 6,785,528, the average population of Indiana's 92 counties is 73,756, with Marion County as the most populous (977,203), and Ohio County (5,940) the least. 54 counties have 30,000 or more people; 17 counties have populations exceeding 100,000, five of which exceed 250,000; and only six counties have fewer than 10,000 people. The average land area is 396 square miles. The largest county is Allen (657 square miles) and the smallest is Ohio (86 square miles). According to the Constitution of Indiana, no county may be created of less than 400 square miles, nor may any county smaller than this be further reduced in size, which precludes any new counties.
County government in Indiana consists of two bodies, the county council and the commissioners.
