What it’s like

The place. Firth is a very small city in Bingham County, Idaho, with the quiet pace that comes with that. Residents are of middle age on the whole, and a four-year degree is held by fewer adults than in the country at large. Winters are cold and fairly snowy, with January the coldest month, and summers turn warm in July.

Work. Residents work mostly in schools, hospitals and social care, with shops, manufacturing and professional and business services also employing many. Across Bingham County, some of the largest workplaces are Bingham Memorial Hospital, Spudnik Equipment Co, which makes potato diggers, harvesters and planters, and Basic American Foods, which dehydrates potatoes. Commutes are of moderate length, and few people work from home.

Things to do. For a day out, the Blackfoot River is a longer drive away and offers water and open country. The Museum of Idaho and the Idaho Potato Museum are also a longer drive away, and both suit a slower afternoon indoors.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Firth’s census tracts, against the rest of the country; all of them together, relatively moderate. 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 Bingham County and the Blackfoot, ID metro.
