If the American states were countries

The USA is an aglomeration of states which have fairly distinct cultures and indentities. If they were broken up into countries how would they fare?
One way to look at this is to consider their GDP, which has been done in this map where the individual states are replaced by countries with similiar GDP.

California is the largest (similiar to France, #8 in the World)

Wyoming is the poorest and compares to Uzbekistan (#101 in the World)

My adopted home of Norway is the same as #28 Minnesota

The UK is #7 in the World and marginally bigger than California

Interestingly the GDP of the whole of Europe is almost idenitical to the USA ($13.7 vs $13.2 billion).

The map is from the excellent StrangeMaps and can be found here.
