What it’s like
The place. Groton is a small community in Middlesex County, Massachusetts, with a population that is small even by the standards of New England towns. Typical home values run high, well above what most of the country sees, and across Middlesex County household incomes are high too. Winters are cold, with January the coldest month and temperatures that stay well below freezing overnight, while summers turn warm in July. Rain and melted snow add up to a fair amount over the course of a year.
Work. Residents work mostly in schools, hospitals and social care, followed by professional and business services, manufacturing and shops. Across Middlesex County, the largest workplaces include Harvard University, the Massachusetts Institute of Technology and Mass General Brigham. Unemployment across the county is a little lower than it was a year earlier, though the county has fewer jobs than it did the year before.
Things to do. The Squannacook River and the Nissitissit River are both a short drive away and suit time by the water. Walden Pond, a reservoir, is a longer drive away, as is the Harvard Art Museums, a museum with a wide collection. Each of these makes a good day out from town.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Groton’s census tracts, against the rest of the country; all of them together, relatively moderate. 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 Middlesex County and the Boston-Cambridge-Newton, MA-NH metro.
