What it’s like

The place. Onarga is a small village in Iroquois County where nearly everyone owns the home they live in, a far higher rate of ownership than most places. Household incomes are above the county's, and the typical home is modest in price. Winters are cold, with January the coldest month and a fair amount of snow, while July brings warm summer days, and rain and melted snow are steady through the year.

Work. Residents work mainly in manufacturing, in schools, hospitals and social care, and in shops. Across Iroquois County, some of the largest workplaces are Walmart, Prairieview Lutheran Homes and the Central CUSD 4 school district. Most people have a short drive to work, and very few work from home.

Things to do. For time outdoors, the Iroquois River and the Iroquois County State Wildlife Area, a protected area, are each a longer drive away. Bayles Lake, a reservoir, is also a longer drive away. Those who like aviation history can visit the Octave Chanute Aerospace Museum, again a longer drive from the village.

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