Former counties

Data published by the old 8 counties

In 2022 the U.S. Census Bureau replaced Connecticut's 8 historical counties, which have had no county government since 1960, with the state's 9 planning regions. Some federal datasets still publish figures by the old counties. Old county lines do not match the new regions, so these figures cannot be split between regions. We show them here as published.

Source: FEMA NFIP flood insurance claims, USAspending.gov. Figures are for the old county as a whole.
