What it’s like
The place. Irwin is a very small city, home to far fewer people than most towns, and almost every home is lived in by the people who own it. Incomes run below the county's, and typical home values are well above what many people expect for a place this size. Winters are cold, with January the coldest month, while July brings warm summer days, and the year's precipitation is modest, split between rain and melted snow.
Work. Residents work mostly in schools, hospitals and social care, with many others in professional and business services, shops, and restaurants, hotels and entertainment. Across Bonneville County, the largest workplaces include Mountain View Hospital, Bonneville Joint District and Eastern Idaho Regional Medical Cente, and the county has added jobs over the past year. The typical commute is long, so many people spend a good part of the day getting to and from work.
Things to do. The closest outdoor draws are all a longer drive away. Bridger–Teton National Forest is the best known, a large protected area for hiking and camping, and Jackson Hole Mountain Resort is a ski area for the winter months. The National Museum of Wildlife Art offers an indoor change of pace, and the Gros Ventre River is a place to fish or simply sit by the water.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Irwin’s census tracts, against the rest of the country; all of them together, very high. 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 Bonneville County and the Idaho Falls, ID metro.
