For those that use US county level data, be aware that Connecticut is changing their county boundaries, names and FIPS codes.
In 2020, the state of Connecticut provided a formal request to the Bureau of the Census to adopt the state’s nine planning regions as county-equivalent geographic units for purposes of collecting, tabulating, and disseminating statistical data, and replacing the eight counties, which ceased to function as governmental and administrative entities in 1960. The Bureau of the Census began implementing this change in 2023 and by 2024 all Bureau of the Census publications will use the nine new county-equivalent planning region boundaries, names, and codes. For example the 2023 Census (TIGER/Line) shapefiles reflect the new county equivalent boundaries, names, and FIPS codes.
