Pennsylvania - Average Distance to Nearest Airport

This page presents statistics and a map.
See information on how and why they were computed.

23.30 mi. = mean distance of a person to his or her nearest major airport
Percent of population within a given distance of a major airport:
PercentileDistance (mi.)
10th percentile6.06
25th percentile11.32
50th percentile (median)20.44
75th percentile31.40
90th percentile46.05

This map displays the major airports in and around Pennsylvania. It shows how the state can divided according to which airport is the closest as the crow flies.

The flags are a sample of 500 census tracts (of 3,210 tracts total) within the state.

On the above map, some census tract flags may look like they are colored for one airport's region but are actually in another airport's region. The census tract flags are colored with which airport they are closest to as the crow flies along the surface of the earth (the Haversine distance formula). The region boundaries that are displayed on map were computed assuming assuming the earth is flat. (The lines that divide regions are a Voronoi diagram, and I couldn't find any algorithm that calculate the lines on a sphere such as the earth.) In short, although a few census tracts may look like they're mislabeled near a boundary, it's actually the boundary that is slightly wrong.
