Selected Updates ...

March upcoming .. urban/rural statistics for 118th Congressional Districts
Census plans to have these data by fall 2023, though scope not yet clear.
ProximityOne will develop these data in March 2023, using these data resources:

1) Census 2020 block to CD 118 equivalence files

2) TIGER "TL22" block shapefiles population, housing units, urban/rural status

3) ~30 block level demographics from the Census 2020 P.L. 94-171 files

The above data are combined to develop a Congressional District by Urban/Rural Dataset; then integrated into a CD118 shapefile

Using census block level data from Census 2020 each state will redistrict their apportioned number seats with new boundaries to be determined mostly in time for the 2022 elections. 118th congressional district basic demographics from Census 2020, retabulated to the 118th boundaries, will be available in 2023. The 118th CD boundaries are provided to the Census Bureau by states and might be integrated into the TIGER public use digital map database released in 2023. More detailed 118th congressional district demographic-economic data will be available from the ACS 2023 expected in late 2024.

About this Section .. goto top
This is the "main" Congressional Districts section. See the updates subsection above that provides links to congressional district related topics focused data and tools to examine geographic, demographic and economic characteristics and change. These topics relate to a wide range of other geographies and data. These include states themselves, state legislative districts, cities/places of population concentration, counties administrative units of states and other geographic levels. Census blocks are the defining smallest geographic element of congressional districts. Increasingly, block groups and census tracts are important in the analysis of congressional districts due to the annual updates based on the American Community Survey (ACS) on the citizen voting age population (CVAP) for these smaller geographic areas.
