What it’s like
The place. Sullivan is a very small town in Cheshire County, New Hampshire, where nearly everyone owns the home they live in. Household incomes run above the county's, and fewer people live below the poverty line than you might expect. Winters are cold and snowy, with January the coldest month, and summers are warm, with July the warmest.
Work. People who live in Sullivan work mostly in schools, hospitals and social care, with others in manufacturing, professional and business services, and shops. Across Cheshire County, some of the largest workplaces are Cheshire Medical Center, Keene State College and Keene School District. The typical commute is a long one, and very few residents work from home.
Things to do. Granite Lake, a reservoir, and Island Pond, a lake, are both a short drive away for time on the water. Granite Gorge Ski Area is also a short drive away, which suits the snowy winters. For a longer outing, Steamtown, U.S.A., a museum, 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 Cheshire 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 Cheshire County and the Keene, NH metro.
