The chart above shows the number of subway stations per mile of track in each state. Only four states have more than one station for every mile of track.
- The difference between the state with the most subway stations per mile of track, New York, and the state with the least (that has a subway system), California, is 1.25.
- New York has 3.58 times the subway stations per mile of track that California does.
- Pennsylvania and California have two subway systems, New York has three, all other states have one.
- Data is from 2017.
- Hawaii is currently working on building a subway system for Honolulu which is slated to have 1.05 stations for every mile of track.
- All figures are rounded to the nearest hundredth.
Considering that California has the second most miles of subway track in the US, but ranks in the middle in terms of number of stations, it is a state whose subway systems encompass a large geographic area but whose stations are placed sparsely on those lines.
