I note a swath of relatively good news stretching from Columbus, Ohio to Washington, DC. This is the exception to the Rust Belt rule that the Bureau mentions as "particularly hard" hit. Looking more closely at the Pittsburgh GDP numbers (Millions of Dollars):
Pittsburgh's metro economy contracted slightly from 2008 to 2009. I expect 2010 will be a return to growth and surpass the 2008 peak. I'll be interested to see how Pittsburgh compares in terms of recovery. We already know that Pittsburgh fared well during the recession. But the speed with which the region leaves its nadir will have a lot to say about the ability to attract migrants searching for opportunity.
