Sweden and North Carolina?

On this page one can see a comparison between the states in the United States and Countries in the world. My friend Paul Hoffman pointed me at it.

Sweden would be on 10th place compared with North Carolina and a GDP of $371 billion, after Georgia (Switzerland), Pennsylvania (Netherlands), New York (Brazil), Ohio (Australia), New Jersey (Russia), Illinois (Mexico), Florida (South Korea), Texas (Canada) and California (France).
