What it’s like
The place. Upper Darby is a township just outside Philadelphia, home to a large population that is somewhat younger than you might expect. Incomes here run below the county's, and the share of households living under the poverty line is a real part of the picture. More homes are lived in by their owners than rented, though renting is common too. Winters are cold, with January the coldest month and a fair amount of snow, and summers are hot, with July the warmest. Rain and melted snow fall steadily across the year.
Work. Many residents work in schools, hospitals and social care, followed by professional and business services, shops, and restaurants, hotels and entertainment. The biggest workplaces in the township include the Upper Darby School District and several supermarkets, among them State Road Foods and Giant Food Stores. Commutes are on the long side, and a good number of people work from home. Unemployment across Delaware County has come down compared with a year ago, and the number of jobs has edged up slightly.
Things to do. Some of the region's best-known sights are only a short drive away. Independence Hall, an archaeological site, is the most famous, and the Philadelphia Museum of Art is a short drive as well. For a day out with family, the Philadelphia Zoo is also a short drive away, and sports fans can reach Lincoln Financial Field, a stadium, just as easily.

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