Say you renamed states for the countries which share the same GDP. This is what you'd get (click the map for a larger image):
A topsy turvy world where Alaska is Belarus and Algeria is West Virginia. California becomes France, but that's not really so crazy.
The Strange Maps blog writes:
The creator of this map had the interesting idea to break down that US GDP into the GDPs of individual states, and compare those to other countries GDPs. What follows is this slightly misleading map, because the economies of the US states and of the countries they are compared with are not weighted for their respective populations.
Pakistan, for example, has a GDP that's slightly higher than Israel's but Pakistan has a population of about 170 million, while Israel is only 7 million people strong. The US states that those economies are compared with (Arkansas and Oregon, respectively) are much closer to each other in population: 2,7 million and 3,4 million.
