What it’s like

The place. Port Byron is a small village in Rock Island County, a place where people tend to know one another. Residents tend to be somewhat older than in many places, and incomes run well above the county's. Nearly all homes are lived in by their owners, and fewer residents live below the poverty line than is typical. Winters are cold and the summers are warm, with rain and melted snow spread through the year.

Work. Residents work mostly in schools, hospitals and social care, with many others in manufacturing, transport and warehouses, and professional and business services. Across Rock Island County, some of the largest workplaces are Tyson Fresh Meats, John Deere Harvester Works and Trinity Rock Island. The county has fewer jobs than it did a year earlier, though unemployment there is lower than it was then. A typical commute is moderate, and a fair number of residents work from home.

Things to do. The Wapsipinicon River and the Buffalo Bill Cody Homestead, a museum, are both a short drive away. The Community Building, a theatre, is also close by. A longer drive brings you to the Figge Art Museum.

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 Rock Island County and the Davenport-Moline-Rock Island, IA-IL metro.
