Most passport rankings count every country as 1 point, so Tuvalu = France.

I made a version where each visa-free door is weighted by how many people actually go there.

So opening France, Spain, the US, China, Turkey etc matters much more than opening tiny islands with Robinson Crusoe as a visitor.

Top result: South Korea, at about 1.45B tourist-arrivals worth of accessible world (thanks to India). Bottom: Afghanistan/Pakistan range, under 50M / 30M. Most open destination: Maldives - 30 day visa for all but Israel. Most overlooked: Burundi - opened the door to the whole world, but nobody came in.

And two more things:

  1. You can compare countries: where can the French go that Belgians can't?

  2. With multiple citizenships, you can build your own passport gang. Will Argentina+Italy beat South Korea?
