People and housing within 5, 10, 25 and 50 miles of Philadelphia
Each circle is centered on 39.9523, -75.1638. The 1,603,797 people counted inside the city limits are more than the 5-mile circle holds, so the limits reach well beyond it in places. The 10-mile circle is the first of these four to hold more. The center of Philadelphia sits at 35 ft (11 m); see the Philadelphia elevation page.

How these figures are made
- Residents and housing are estimates of the April 1, 2020 Census count, added up from census tracts. A tract on the edge counts by the share of its land area inside the circle, and estimates are rounded to three significant figures.
- Town and ZIP populations are 2020 Census counts for the whole place or ZIP code area. Each is listed when its center point is inside the circle, so part of it may lie outside.
- Distances are straight lines from the center point, not road miles. A circle crosses state lines and shorelines. The Census covers only the United States, so any part of a circle across an international border adds no residents, towns or ZIP code areas.
The radius map tool page explains the method, how it was tested and its limits.
