City incorporation requires a Special Act by the Connecticut General Assembly.
All cities in Connecticut are dependent municipalities, meaning they are located within and subordinate to a town.
Towns in Connecticut are allowed to adopt a city form of government without the need to re-incorporate as an inner-city.
Connecticut state law also makes no distinction between a consolidated town/city and a regular town.
Note: There are currently 21 cities in Connecticut and those with a population greater than 100,000 are listed in bold.
