What it’s like
The place. Marne is a very small city in Cass County, in western Iowa, where most people know their neighbors by name. Winters are cold and snowy, summers are warm, and rain and melted snow arrive steadily through the year. The town's quiet pace suits those who prefer open country and a close-knit community.
Work. Many residents work in schools, hospitals and social care, or in local shops. Manufacturing and farming, forestry and mining also provide work for people here. Across Cass County, job numbers have dipped lately, which is worth keeping in mind for anyone weighing a move.
Things to do. The Museum of Danish America is a museum a longer drive away and is one of the best known sites in the area. Elk Horn Creek, a river a short drive away, offers a close place for a walk or a quiet afternoon outdoors. Prairie Rose State Park, a park a longer drive away, is another option for time outside.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Marne’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 Cass County.
