What it’s like
The place. Marble Rock is a very small Iowa city, one of the smaller places in Floyd County, where neighbors tend to know one another. Winters are cold, with January the coldest month and a good deal of snow, while summers are warm and July is the warmest stretch of the year. Home values are modest, and not many adults have a four-year degree.
Work. Residents work mostly in schools, hospitals and social care, with manufacturing, shops and the building trades close behind. Across Floyd County, some of the largest workplaces are Zoetis, which makes vaccines, the Charles City Community School District and Floyd County Hospital. The typical commute is a fairly long one, and very few people work from home.
Things to do. The Winnebago River is a short drive away, and it is the nearest of the outdoor options. Farther afield, Beeds Lake State Park is a protected area for time outdoors, and the MacNider Art Museum is a place for a quieter afternoon. Parker's Opera House is a theatre, also a longer drive away.

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