Thirty-four (34 counties) of the fifty-six (56) counties were updated following the creation of the new Montana legislative districts. Voting Precinct boundaries have been aligned to MSDI administrative boundaries, PLSS, and parcels and projected to the Montana State Plane. Initially, the voting or election precincts were obtained from the local county offices by the Montana Department of Commerce through an FY2019 Montana Land Information Act (MLIA) Grant. The contractor used data (obtained from the counties) to digitize voting district boundaries following the recommendations of the U.S. Census Bureau Redistricting Data Program. Source data may be GIS digital data or manually digitized from maps. Key fields included 2-digit state FIPS, 3-digit county FIPS, Precinct Number, Precinct Name, County Name, and Data Date. The Voting Precincts along with the Montana Legislative Districts for 2014-2023 are available for download here: https://ftpgeoinfo.msl.mt.gov/Data/Spatial/MSDI/AdministrativeBoundaries/Historic/According to MCA 13-3-101 the governing body of each county shall establish a convenient number of election precincts, equalizing the number of electors in each precinct as nearly as possible. According to MCA 13-3-102 the county governing body may change the boundaries of precincts, but not within 100 days before any primary or between a general election and the primary for that election. When changes are required to make precinct boundaries conform to legislative district boundaries following the adoption of a districting and apportionment plan under Article V, section 14, of the Montana constitution or other district boundaries changed by the districting and apportionment plan, the changing of precinct boundaries must be accomplished within 45 days of the filing of the final plan.
