What it’s like
The place. Williamsfield is a small village in Knox County, Illinois, and almost everyone who lives there owns their home. Household incomes run well above the county's, and fewer people live below the poverty line than you might expect. Winters are cold, with January highs near freezing and lows well below it, and summers are warm, with July the warmest month; a fair amount of snow falls each year, and rain and melted snow add up to a moderate yearly total.
Work. Residents most often work in schools, hospitals and social care, followed by manufacturing, transport, warehouses and utilities, and the building trades. Fewer adults hold a four-year degree than in many places, and most people commute by car rather than working from home. Across Knox County, some of the largest workplaces are Galesburg CUSD, St. Mary Medical Center and Knox College.
Things to do. Snakeden Hollow State Fish and Wildlife Area is a protected area a short drive away, a place for walking and watching wildlife. A longer drive brings you to Jubilee College State Park, another protected area, and to the Peoria Zoo, a zoo in the Peoria area. The Spoon River, also a longer drive away, is a good choice for time by the water.

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