What it’s like

The place. Dennis is a small Cape Cod community where nearly everyone owns the home they live in, far more than in most places. Household incomes run higher than across Barnstable County, and relatively few residents live below the poverty line. A large share of adults hold a four-year degree, and the typical commute is short. Winters are cold, with January the coldest month, highs near freezing and lows below it, and summers are warm without being hot, with July the warmest month. Rain and melted snow add up to a fair amount over the year.

Work. Many residents work in schools, hospitals and social care, followed by professional and business services, shops, and restaurants, hotels and entertainment. Across Barnstable County, the largest workplaces include Cape Cod Hospital, Barnstable Schools and Cape Air. The job count across the county has been close to flat, and unemployment there is about where it was a year ago.

Things to do. Scargo Lake and Follins Pond are lakes in or beside town, and the Winslow Crocker House, a museum, is there as well. A short drive away is Nickerson State Park, a protected area with woods and ponds. The Cape Cod National Seashore, a protected area, is a longer drive away.

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

  1. Coastal floodingRelatively high
  2. HurricanesRelatively moderate
  3. LightningRelatively moderate

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Dennis’ census tracts, 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 Barnstable County and the Barnstable Town, MA metro.
