Map of the counties of colonial Connecticut, 1766.

There are eight counties in the U.S. state of Connecticut.

Four of the counties – Fairfield, Hartford, New Haven and New London – were created in 1666, shortly after the Connecticut Colony and the New Haven Colony combined. Windham and Litchfield Counties were created later in the colonial era, while Middlesex and Tolland Counties were created after American independence (both in 1785). Six of the counties are named for locations in England, where many early Connecticut settlers originated; Fairfield County was named after the salt marshes that bordered the coast, while New Haven County was named for the New Haven Colony.[1]

Although Connecticut is divided into counties, there are no county-level governments, and local government in Connecticut exists solely on the municipality level.[2] Almost all functions of county government were abolished in Connecticut in 1960,[3] except for elected county sheriffs and their departments under them. Those offices and their departments were abolished by an act of the state legislature effective in December 2000. The functions the county sheriffs' departments played were assumed by the newly organized State Marshal Commission and the Connecticut Department of Corrections.[4]

These counties are used in legacy geography, such as identifying land, national statistics and firmly within personnel rostering and court jurisdictions in the state's judicial and state marshal system. However, the three most populous—Fairfield, Hartford and New Haven—are as to many types of jurisdiction subdivided.[5]

In 2019 the state recommended to the United States Census Bureau that the nine Councils of Governments replace its counties for statistical purposes. According to the Census Bureau, "Connecticut's COGs/Planning Regions have the authority to carry out administrative functions that are typically found among counties in other states."[6] This proposal was approved by the Census Bureau in 2022, and will be fully implemented by 2024.[7]

Comparison of county boundaries to planning regions[8]

The United States Census Bureau formally recognized the planning regions/councils of government as county equivalents in the Federal Register on June 6, 2022. A draft notice of potential recognition would have adapted the existing FIPS codes for the eight "legacy counties", however in response to submitted comments, the bureau retired the codes and assigned new ones to more clearly illustrate the break in geographic continuity. The Census noted that there is substantial correlation between the historic county borders and planning regions, however planning regions may incorporate towns from several counties. The bureau notes that the recognition of planning regions as county equivalents was unique to the specific conditions in Connecticut, and would not constitute a binding precedent on similar conditions in other states.[9]

  2. ^ Officially, Connecticut has no county seats.[11] The listed communities are instead historical county seats.
