There’s no doubt that the United States is the world’s largest economy, but what about its constituent state? California, for example, is the world’s eight or ninth largest economy, depending on whom you ask. Curious about the rest? The Economist has you covered with a great map that identifies which country comes closest to matching a state GDP-to-GDP. While it may seem shocking that Vermont most closely matches up with Yemen, an impoverished developing nation, keep in mind that the map uses simple GDP, not GDP per person. The flip side of the map identifies which countries are closest in population to each state.
