Just a few years ago, Oklahoma boasted the fastest growing economy in the country, as its gross domestic product surged 6.6%.
But in 2010, that growth fell to a sluggish 1.0%.
Why? The state's oil industry grew so quickly with surging energy prices back in 2008, but during the recession and even into 2010, U.S. demand for energy declined.
Oil remains a strong sector for the state though, and now that energy demand is rising again, it's likely to help Oklahoma's economy pick up speed in 2011.
