From Strange Maps.
The creator of this map has had the interesting idea to break down that gigantic US GDP into the GDPs of individual states, and compare those to other countriesâ€™ GDP. What follows, is this slightly misleading map â€“ misleading, because the economies both 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 thatâ€™s slightly higher than Israelâ€™s â€“ but Pakistan has a population of about 170 million, while Israel is only 7 million people strong. The US states those economies are compared with (Arkansas and Oregon, respectively) are much closer to each other in population: 2,7 million and 3,4 million.
