What it’s like
The place. Derry is a small borough in Westmoreland County, with a population on the smaller side and a median age a little older than many places. Incomes here run well below the county's, more people live below the poverty line than one might expect, and most homes are lived in by their owners. Winters are cold and the summers pleasantly warm, with a good deal of rain and melted snow through the year.
Work. Residents work mostly in manufacturing, in schools, hospitals and social care, and in shops. Across Westmoreland County, some of the largest workplaces are Westmoreland Regional Hospital, UPS and Elliott Group, a maker of compressors. Unemployment across the county has eased over the past year, though the number of jobs there has slipped slightly from the year before. Fewer adults hold a four-year degree than in many places, and commutes are of a typical length, with some people working from home.
Things to do. A short drive away, Idlewild and Soak Zone is an amusement park, and Keystone State Park offers a protected area of woods and water to walk through. For a longer outing, the Westmoreland Museum of American Art is a museum, and the Flight 93 National Memorial is a protected area that draws visitors from well beyond the region. The Conemaugh River, also a longer drive away, suits those who like to spend time by the water.

Natural hazards
- LightningRelatively moderate
FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Derry’s census tracts, 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 Westmoreland County and the Pittsburgh, PA metro.
