The chart above shows the number of annual riders for every kilometer of track in each state. One million annual riders is the equivalent of 2,740 riders a day. So the Netherlands has 3,808 daily riders for every kilometer of track while Hungary has 29,452.
- The difference between the state with the most annual riders per kilometer of track, Hungary, and the state with the least (that has a subway system), the Netherlands, is 9.36 million.
- Hungary has 7.73 times the annual riders per kilometer of track that the Netherlands does.
- Italy has seven subway systems, France has six, the United Kingdom and Germany each have four, Spain has three, and the Netherlands has two, all other states have one.
- The median number of annual riders per kilometer of track in states that have a subway is 3.27 million and the mean 4.00 million.
- Data is from 2017.
- Greece is currently working on building a subway system for Thessaloniki which is expected to have 3.70 million annual riders per kilometer of track.
- All figures are rounded to the nearest hundredth.
The United Kingdom has the most subway track but comes in second in subway riders while France leads in subway riders and comes in fourth in length of track. It is Hungary however who ranks first in number of riders per kilometer of track as its relatively small subway system packs in a healthy amount of riders.
