Passports, Ranked by 'Power'

Anyone who's lucky enough to claim citizenship in the United States shouldn't forget to count among their (many, many) privileges the unique position of holding a U.S. passport, which allows travelers to visit 147 countries visa-free. In practical terms, that means international travel is both cheaper and easier than it is for citizens of (many, many) other countries.

For a visual reminder of this fact, check out Passportindex.org, which offers "power rankings" for each global passport calculated by tallying a country's "visa-free score," or how many countries holders can visit without either an advance visa or by purchasing a visa on arrival. By this measure, the U.S. passport holds a No. 1 ranking, along with the U.K., Sweden, Germany, and Finland.
