The tabs below represent the unique congressional sessions as collected by the U.S. Census Bureau through the Redistricting Data Program. Each tab contains information specific to that session's boundary collection along with other relevant products generated in support of any changes. Typically, new products are generated only when changes to congressional districts are reported between sessions. Any changes to congressional plans are submitted to the Census Bureau by non-partisan state liaisons, identified by the governor and legislative leadership of each state at the beginning of each decade's Redistricting Data Program. Once these plans are processed and inserted into the MAF/TIGER database, the Census Bureau generates verification materials for each state to review and certify as accurate. Any reported changes to the verification materials were incorporated into these final products.
The U.S. Census Bureau's Redistricting Data Program does not collect the congressional and state legislative district boundaries for the cycle that aligns with the decennial census. The 117th congressional and 2020 state legislative districts were not collected as they are the cycle that aligned with the 2020 Census. When the Census Bureau collects congressional and state legislative districts, they are inserted into our geographic database. This allows the boundaries to be reflected in tabulation and geographic products. Therefore, the most recent congressional and state legislative district boundaries collected and reported by the Census Bureau are those for the 116th congressional and 2018 state legislative districts.
North Carolina was the only state that had changes to their congressional districts between the 116th and 117th Congresses. Since those changes occurred during the cycle that aligned with the 2020 Census, those changes were not collected by the Census Bureau. Therefore, the boundaries for North Carolina in census data still reflect those of the 116th Congress. For more information about the changes to congressional districts in North Carolina for the 117th Congress, please visit the North Carolina General Assembly's webpage. Please note that the N.C. 117th boundaries on their website are those enacted in 2019.
Since there were no changes reported between the 116th and 117th Congresses for other states, the 116th congressional district boundaries can be considered the same as those for the 117th Congress.
Our next collection cycle for congressional and state legislative districts is for the 118th Congress and 2022 state legislative districts. Materials from that collection will start to be made available in December of 2022.
