Connecticut FIPS Codes for Planning Regions
Connecticut’s eight counties, which exist only as boundary lines with no county-level governments, are now being replaced with Connecticut’s nine planning regions for the purposes of county-level data reporting.
In Connecticut, as in the rest of New England, AP tabulates elections results at the township reporting unit level, and then the results are aggregated to the county level using the FIPS codes of counties or county equivalents. Instead of using Connecticut county FIPS codes, AP will now aggregate the data using the FIPS codes of the planning regions, which are the new "county equivalents" in Connecticut.
The township reporting unit names and IDs will remain the same; only the FIPS codes are changing.
|
|
This change is effective for the August 13, 2024 state primary. All elections prior to this will retain the FIPS codes that were in place at the time. |
|
|

ImportantThe table below shows the mapping for the Connecticut township reporting units (which are not changing) to the new FIPS codes and the corresponding planning region names. The previous FIPS codes and county names are also included for reference.
