About this Section .. goto top
The 118th Congress runs from January 1, 2023 through December 31, 2024. The 2024 House of Representatives elections will be held on November 5, 2024, to elect representatives from all 435 congressional districts for the 119th Congress. Those elected will serve in the 119th Congress with seats apportioned among the states based on the Census 2020. Using census block level data from Census 2020 each state redistricts their apportioned number seats with new boundaries for the 2024 elections. While most 119th congressional district boundaries will be the same as the 118th boundaries, some change due to revisions. The 118th CD boundaries are provided to the Census Bureau by states and are integrated into the TIGER public use digital map database released in 2023. More detailed 118th congressional district demographic-economic data are available from the ACS 2022 released in 2023.
