From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Arton Capital's ‘Passport Index’ is an interactive website which “collects, displays and ranks the passports of the world."

Using data from the International Air Transportation Agency (IATA) as well as individual travelers, the site's creators crunched the numbers and determined a passports' Visa Free Score, or the number of countries that allow its holder to enter without a visa or obtain one upon arriving. The higher the Visa Free Score, the higher the "Passport Power Rank."

Unsurprisingly, the US and UK are the most widely accepted in the world with 147 nations opening their doors to travelers visa-free. Tied for second place are France, Germany, and South Korea, with 145 countries. Nations in conflict like the Palestinian Territories and South Sudan bring up the rear.

The site also features a map where users can click on a country to see the corresponding passport. If power rankings aren't your thing, you can sort the passports by color.

As part of an ongoing, interactive project, users are also invited to contribute pictures of their passports to make a more complete database.
