What it’s like
The place. Grantham is a small New Hampshire town in Sullivan County where every home is lived in by its owners, and where incomes are not low by any measure the data shows. Homes here are valued well above what is typical for the county, and winters are cold and snowy, with January the coldest month and July the warmest, when the days turn pleasantly warm. Rain and melted snow fall across the year, and the snow piles up enough that shovels and plows are part of ordinary life.
Work. Residents work mostly in schools, hospitals and social care, with others in manufacturing, shops, and professional and business services. Across Sullivan County, some of the largest workplaces are Whelen Engineering Company, Sturm, Ruger & Co and Valley Regional Hospital. Commutes are moderate, and a good number of people work from home. Unemployment across the county is low and a little lower than a year earlier, and the number of jobs has edged up.
Things to do. Eastman Pond is a lake in or beside town, and Crystal Lake, a reservoir, and Whaleback, a ski area, are both a short drive away. The Enfield Shaker Museum is also a short drive off. For a longer outing, Lake Sunapee and the Saint-Gaudens National Historical Park are both a longer drive away.

School districts come from the Common Core of Data (NCES, 2023–24) and hospitals from their Medicare cost reports (CMS, 2023); FTE marks full-time equivalent staff. Not listed: many offices and banks, which need not report to OSHA; military bases, whose staff OPM withholds; and, in about half the states, city and county governments.
Natural hazards
- Ice stormsRelatively moderate
FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms across Sullivan 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 Sullivan County and the Lebanon, NH-VT metro.
