Eldan GoldenbergOnce I found that Federal Register announcement I could piece it together. From 1960 until 2022, the US Census Bureau was using outdated labels for subdivisions within Connecticut. Starting in 2022, they now use the up to date planning region names, which have been issued new FIPS codes because they don't have a perfect 1:1 correspondence with the old counties. The problem for me is that while the 2018-2022 ACS 5-year estimates have to use 2010 Tract geometries, they use the 2022 codes. (4/?)
