In the waning days of the American Empire, our once powerful passport now lacks the cachet that it once possessed. Now it’s time for other nation’s passports to edge ours aside.

It ranks each national passport by a “mobility score”, i.e. how much it allows holders of each passport to travel the world. It reveals the vast inequality inherent in your place of birth. It’s OK to gloat if your passport opens borders for you.
