List of municipalities of Connecticut by population
This is a list of municipalities in Connecticut in order of population from greatest to least. Connecticut's fundamental form of local government is the New England town. The state is composed of 169 towns. Nineteen of these towns are chartered as cities, in addition to one borough. These nineteen cities and one borough all share the same border with their namesake towns and have a merged city–town government. In addition, there are two cities and eight boroughs which constitute only a section of the towns in which they are situated. Since their populations are already included in the census figures of their parent towns, the non-coterminous cities and boroughs, while listed for comparison purposes, are not given a ranking in the population roll. The list includes all current municipalities that are chartered by the Connecticut General Assembly and does not include former cities such as Willimantic. Figures are based on the 2008 U.S. Census Bureau estimates except where otherwise noted. The top seven cities are listed according to 2010 census data.
