What it’s like
The place. Fairfield is a small town in Teton County, home to a young community with a median age well below that of many rural Montana towns. Household incomes sit a little below the county's, and relatively few residents live below the poverty line. Winters are cold, with December the coldest month, summers are warm, and the year brings little moisture, mostly as rain and melted snow.
Work. Residents work mainly in schools, hospitals and social care, followed by shops, the building trades, and restaurants, hotels and entertainment. Across Teton County, the largest workplaces include Benefis Teton Medical Center, the Choteau Elementary school district and the Fairfield Elementary school district. The county has added jobs over the past year, and unemployment there is low and a little lower than a year earlier. Commutes are modest, and a fair number of people work from home.
Things to do. For time outdoors, First Peoples Buffalo Jump State Park is a protected area a longer drive away. Freezout Lake Wildlife Management Area, a park, and Priest Butte Lake are also a longer drive away. For a rainy day, The Montana Dinosaur Center is a museum, again a longer drive away.

Natural hazards

- WildfireRelatively moderate
FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Fairfield’s census tracts, against the rest of the country; all of them together, relatively low. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.
From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on Teton County and the Helena, MT metro.
