Interesting article and map in the Atlantic Cities.
"The map above charts the economic growth of metros over the past decade (2001 to 2010). For the U.S. as a whole, GDP grew at an average annual rate of 1.46 percent this period, with the average rate for all metros being slightly better, 1.63 percent. More than half (53 percent) of metros (194 of 366) were above the national average. Most metros posted positive GDP growth (there are far more green dots than red), but the red dots are concentrated in and around the Midwest."
