About Connecticut

Connecticut had 3,605,944 residents at the 2020 Census, in 169 towns and cities. The busiest commercial markets follow the interstates: I-95 along the shore from Greenwich through Bridgeport, New Haven and New London; I-91 up the Connecticut River valley from New Haven through Hartford toward Springfield; and I-84 from Danbury through Waterbury and Hartford toward Boston.

The state has had no county government since 1960. Zoning, permits and property taxes are set by each town, so the town is usually the right place to start when comparing commercial property.
