Municipalities of Connecticut Towns (light grey) and cities (dark grey) of Connecticut
Location State of Connecticut Number 169 Populations 785 (Union ) – 148,654 (Bridgeport ) Areas 4.98 square miles (12.9 km2 ) (Derby ) – 61.59 square miles (159.5 km2 ) (New Milford ) Government
The U.S. state of Connecticut is divided into 169 municipalities , including 19 cities, 149 towns and one borough, which are grouped into eight historical counties , as well as nine planning regions which serve as county equivalents .
Towns traditionally have a town meeting form of government; under the Home Rule Act , however, towns are free to choose their own government structure. Nineteen of the towns in Connecticut are consolidated city-towns, and one (Naugatuck ) is a consolidated borough-town.
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. However, except for one, all currently existing cities in Connecticut are consolidated with their parent town . Former inner-cities are listed in a separate table below.
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. Bolded city names indicate the state's largest cities, with the most populated being Bridgeport . Currently, Tolland County and Windham County are the only counties in Connecticut without a single city in them.
