The Redistricting Data Program (RDP) provides states the opportunity to delineate voting districts and to suggest block boundaries for use in the 2030 Census redistricting data tabulations (Redistricting Data - Public Law 94-1717 Summary File). The Census and Economic Information Center is the state appointed non-partisan liaison who serves as the Census Bureau’s point of contact throughout all phases of the program. In this capacity, we submit voting districts, congressional districts and state legislative districts to the U.S. Census Bureau. We do not define the boundaries. Voting district boundaries are defined by local government representatives and compiled by the Montana Secretary of State and the Montana State Library. Congressional and state legislative districts are draw by the Montana Districting and Appointing Commission and compiled by the Montana Legislative Services Division.
