Well, we would be #78 if every U.S. metropolitan area were treated as a separate country. Our 2011 GDP was just $200 million less than Hungary, which maybe doesn't sound all that impressive, but Hungary does have a population around 10 million, compared to our 2 million or so.
What really surprised me is how our local economy is (significantly) bigger than a number of other Midwestern or East Coast metro areas, including:
St. Louis (#79)
Riverside/Inland Empire (#84)
Kansas City (#85)
New Orleans (#104)
In fact, there are only 19 metro areas ahead of us, none terribly surprising except maybe Minneapolis/St. Paul.
