The chart above shows the number of annual riders for every mile of track in each state. One million annual riders is the equivalent of 2,740 riders a day. So Ohio has 849 daily riders for every mile of track while New York has 18,986.
- The difference between the state with the most annual riders per mile of track, New York, and the state with the least (that has a subway system), Ohio, is 6.62 million.
- New York has 22.35 times the annual riders per mile of track that Ohio does.
- Pennsylvania and California have two subway systems, New York has three, all other states have one.
- The median number of annual riders per mile of track in states that have a subway is 1.69 million and the mean 2.22 million.
- Data is from 2017.
- Hawaii is currently working on building a subway system for Honolulu which is expected to have 2.12 million annual riders per mile of track.
- All figures are rounded to the nearest hundredth.
Considering that New York has the most miles of track in the US by a large margin, but still manages to top this list shows how large the chasm is in subway ridership between New York and the other states.
