What it’s like

The place. Sullivan is a small village in Jefferson County, Wisconsin, with a population that keeps it quiet and close-knit. Fewer homes are lived in by their owners than across much of the country, and a four-year degree is less common among adults here than in many places. Winters are cold and snowy, with January the coldest month, while summers are warm, and the year brings a fair amount of rain and melted snow.

Work. Residents work mostly in schools, hospitals and social care, in shops, in manufacturing, and in restaurants, hotels and entertainment. Across Jefferson County, some of the largest workplaces are Fort Atkinson Memorial Hospital, Standard Process and Watertown Unified School District. Many people commute a fair distance to work, and some work from home.

Things to do. Lower Nashotah Lake and Upper Nashotah Lake are both a short drive away, and so is the Scuppernong River, for time on the water or along the banks. Wisconsin Brewing Company Park, a stadium, is also a short drive away. For a longer outing, Aztalan State Park, an archaeological site, is a longer drive away.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms across Jefferson County, 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 Jefferson County and the Watertown-Fort Atkinson, WI metro.
