Coverage analysis
What 60 minutes covers in Philadelphia.
Philadelphia's drive-time geometry is shaped by two rivers (the Delaware and the Schuylkill), a constrained bridge network into New Jersey, and a Main Line suburban corridor along the old Pennsylvania Railroad. Trade areas frequently span four states' worth of tax and regulatory regimes.
At 60 minutes, the Philadelphia isochrone captures the metro-wide reach — a regional footprint where destination-category businesses draw from a wide geographic spread. Unlike a 400–1,200 km² circle, the real road-network polygon follows Philadelphia's actual highway corridors, accounts for bridge and interchange chokepoints, and respects the natural and built barriers that force drivers to detour.
Best-fit categories at 60 minutes: Distribution center, regional franchise territory, e-commerce fulfillment, hospital system, workforce housing. The 60-minute isochrone is the standard input for regional territory design and logistics network planning.
The city-level population of 1,603,797 and a median household income of $52,649 give a sense of Philadelphia's economic density, but the figure that matters for site selection is the population inside the polygon — not the city as a whole. That number shifts dramatically depending on whether you're drawing from a high-density urban core or a lower-density suburban corridor. Use the tool above to set your actual candidate location, then generate the isochrone to see the real catchment.
