Census County-Equivalent Changes
We will be updating our data to reflect 2022 Census boundaries starting the week of December 12, 2022.
The US Census has released new and updated boundaries and names for several counties and county equivalents in the 2022 Census boundary data. Detailed information on the significant change in Connecticut counties is available from the Census Bureau: https://www.federalregister.gov/documents/2022/06/06/2022-12063/change-to-county-equivalents-in-the-state-of-connecticut.
More information on county changes over time is available at https://www.census.gov/programs-surveys/geography/technical-documentation/county-changes.2020.html
What is changing:
- All county boundaries in Connecticut have been reworked and renamed
- Some county-equivalent boundaries and names in Alaska have changed
- The counties we deliver will be changing to reflect the new counties
- The verse metadata file will be updated to reflect the new counties and remove the retired counties.
- Our Census identifiers (tract, blockgroup and block) will be updated to reflect 2022 Census boundaries
