What it’s like

The place. Darby is a borough in Delaware County, just outside Philadelphia, and it is one of the older communities in the area. The town is home to a younger population than many places in the region, and renting is common, with homes lived in by their owners making up a smaller share than across much of the county. Household incomes run well below the county's, and more residents live below the poverty line than is typical, while relatively few adults hold a four-year degree. Winters are colder than in much of the country, and summers turn hot in July. Snow and rain fall through the year.

Work. Residents of Darby work mostly in schools, hospitals and social care, followed by shops, transport and warehouses, and manufacturing. Within the borough itself, the largest workplaces include Mercy Fitzgerald Hospital and the nursing home operator Center Management. The commute to work is a long one, and a small number of people work from home. Unemployment across Delaware County is lower than it was a year ago, and the county's job count has edged up slightly.

Things to do. Independence Hall, an archaeological site, sits among the city's best known historic places and is a short drive away. The Philadelphia Museum of Art is a short drive away as well. For sports, Lincoln Financial Field is a stadium a short drive from town, and the Franklin Institute is a museum for science-minded visits.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Darby’s 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 Delaware County and the Philadelphia-Camden-Wilmington, PA-NJ-DE-MD metro.
