The core TIGER/Line Files and Shapefiles do not include demographic data, but they do contain geographic entity codes (GEOIDs) that can be linked to the Census Bureau’s demographic data, available on data.census.gov.
All legal boundaries and names are as of January 1, 2023. The 2023 TIGER/Line Shapefiles were released on November 22, 2023.
The following national-scale layers have been included this year: CBSA, CSA, and METDIV. The following layers are gone permanently and are no longer maintained by the Census Bureau: CNECTA, NECTA, and NECTADIV.
For the 118th Congressional District shapefiles, all legal boundaries and names are as of January 1, 2020, with the exception of the 118th Congressional Districts and the State Legislative Districts, which are as of January 1, 2023. A special county layer for the state of Connecticut is included with boundaries and names as of January 1, 2022 for reference purposes because the counties in this state have been significantly changed since 2020.
