Have you ever wondered about just how strong America's metropolitan areas perform economically? The very best way to judge the scale of these powerhouses is by comparing them with the closest equivalent nations. The New York metropolitan area
is the 13th largest economy in the world. In 2013, its GDP was $1.47 trillion, very close to that of Australia. The Los Angeles-Long Beach-Anaheim metropolitan area matches Turkey's $827 billion GDP while Chicago-Naperville-Elgin is above Sweden on $590.
