How many planning regions does Connecticut have?
Connecticut abolished county government in 1960 — the eight legacy counties still appear on maps and in property records but have no administrative role. In 2022 the US Census Bureau adopted the state's nine planning regions as its county-equivalents for federal statistics, and this page reflects that current classification. Planning regions are functionally identical to counties in every other state for Census purposes.
The largest planning region by land area is Capitol Planning Region at 0 square miles, home to about 977,746 residents.
At the other end of the scale, Northeastern Connecticut Planning Region has only about 94,710 residents.
Connecticut’s capital is Hartford, while the largest city is Bridgeport — a common pattern in the United States, where many states placed their capitals in smaller, more central towns rather than their largest commercial hubs.
