The State of Montana Districting and Appointment Commission ensures that each house district has equal representation every ten years following each U.S Census. According to 2020 Census data, Montana has a population of 1,084,225 people. This is an increase of 94,810 people since the 2010 Census.

Since the Montana House of Representatives currently has 100 representatives, each of the 100 districts must be divided evenly by population. Senate districts are required by the state constitution to be composed of two contiguous house districts. Each of the 50 senate districts must be divided evenly by population. The Missoula County Commissioners held public meetings and adopted new precinct maps in 2023.

A precinct is a territorial unit for elections. This unit is a subsection of an approved Montana House District as established by the Montana Redistricting Commission. A precinct is used by political parties to elect precinct committee members. They are also a basis for a ballot style in a federal election, and a ballot style is used to ensure the inclusion of correct ballot issues, candidates and proper candidate rotation. Candidate rotation is required for federal elections and ensures that multiple candidates in the same race have their name listed at the top of the contest an equal number of times.

A precinct may be divided into two or more polling locations. Polling locations are public buildings throughout the county provided for non-absentee voters to vote in-person on Election Day.
