The wealth of US cities

Many US metro areas have economies that rival those of entire countries, according to a new analysis by the US Conference of Mayors. Based on economic output, or gross metropolitan product, the Greater New York City and Los Angeles regions would rank among the world's top 20 economies. The Boston area, with $347 billion in economic output, comes in at 41, ahead of Denmark, Singapore, and Hong Kong.
