What it’s like

The place. Putnam is a small town in Putnam County, Illinois, where most homes are lived in by their owners. Across the county, residents are older on average than people in the country as a whole. Winters are cold, summers are warm, and rain and melted snow fall heavily over the course of a year.

Work. Across Putnam County, many residents work in schools, hospitals and social care, in manufacturing, in shops, or in transport, warehousing and utilities. Unemployment is lower than it was a year earlier, though the number of jobs dipped slightly over the last year. Few people work from home, and fewer adults hold a four-year degree than in many parts of the country.

Things to do. Big Bureau Creek, a river a short drive away, is among the best known places nearby. Dixon Waterfowl Refuge, a protected area also a short drive away, is another option for time outdoors. Senachwine Lake, a lake in or beside town, is the closest of these to home.

Natural hazards

FEMA rates every natural hazard here relatively low or very low.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms across Putnam County, against the rest of the country; all of them together, very 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 Putnam County and the Ottawa, IL metro.
