Montana State Legislature

Legislative Redistricting Plan (adopted 2/12/13)

The final legislative redistricting plan, including 100 House districts and 50 Senate districts, was adopted on February 12, 2013.

The official plan is the block equivalency file that lists each U.S. Census Block and the district to which it is assigned. Because those files are lengthy text files that are rendered meaningful only with with GIS software, additional materials -- including district maps and reports -- will be produced to help illustrate the new districts. These additional files, reports, and maps will be posted as they become available.

Maps of House and Senate Districts

These maps reflect the 100 House Districts and 50 Senate Districts adopted by the commission on 2/12/13. The maps show Senate Districts, which are composed of two nested House Districts. The House District numbers appear in parantheses after each Senate District along with a list of counties in that Senate District.

In the maps themselves, Senate District labels show which holdover Senator is assigned to the district, if any. To see a full list of which House Districts make up each Senate District, the counties in the Senate District and the holdover senator assignments, please refer to the list in the Senate Districts section above.

For a more detailed view of the districts, including a street-level view, please use the Google Earth or Google Maps features available in the Statewide View section.

Note: these maps are not the official boundary designations for House or Senate districts. Official descriptions of House districts are created by the counties not the Legislative Services Division. These maps are meant to be used for general reference only.
