Indiana is a state located in the Midwestern United States. Except as noted, all cities are "third-class" cities with a seven-member city council and an elected clerk-treasurer. *Second-class cities had a population of at least 35,000 and up to 600,000 at time of designation, and have a nine-member city council and an elected clerk. **Indianapolis is the only "first-class" city in Indiana under state law (designed to protect its status as the only first class city), subjecting it to Unigov. To become a city of any class, however, a settlement must have a population of at least 2,000.
