If the greater New York area were its own country, it would be the 11th largest economy in the world at $1.4 trillion (2009 dollars) – this is roughly the size of South Korea’s economy, and larger than Russia, Spain, or Australia’s. It accounts for 6% of U.S. population and a tenth of U.S. GDP.
Bet you didn’t know that the small city (170,000 people) of Midland, Texas has the highest GDP per capita of all ‘metropolitan’ areas in the U.S. at $175K. Why? Booming oil & gas industry.
