A passport from the United States allows its citizens free access to 172 other countries.

But not all travelers have such an overwhelming spread of choices: Residents of Iraq, for example, can access only 31 countries with their passports. Venturing away from Afghanistan? Your options dwindle to 28 countries.

In this infographic map from the folks at GOOD, countries are color-coded based on the “power” of their passports. The darker in color, the more freedom that country’s residents have to travel. Lighter orange colors mean residents can visit fewer countries with their passports.
