The following information was self-reported by legislators shortly before each legislative session, in response to a questionnaire from the Legislative Services Division. Some information (e.g., place of birth and occupation) was taken from Lawmakers of Montana: Legislative Session of 2025 (Copper Book). In some cases, legislators may have indicated more than one response, resulting in a total of more than 150, which is the total number of legislators. And some legislators may not have responded to some questions, resulting in a total of less than 150.
Demographic information includes: Gender, Age, Party Affiliation, Occupation, Education, Race, Veteran Status, and Place of Birth.
