Hasta La Ideas

At last, the worlds of cartography, vexillology and population statistics meet! This map was inspired by earlier maps of the US, with its states renamed for countries with a similar GDP (see posts #131 and #135).

It shows each US state covered by the flag of a country with a population of comparable size. This map was made by James Richards, who also sent in a list of the pairs of US states and flags of corresponding countries. But I agree with him that “unlabeled, it’s a fun test of your knowledge of nations, can you guess them all?”

Update: the full list is posted as provided to me by Mr Richards in comment #36.
