4. Sioux Falls, S.D.

For each metropolitan area, the percentage change in unemployment rate from Nov. 2010 to Nov. 2011 was determined. That percentage change was then subtracted from a given city's Nov. 2011 unemployment rate. (For example, Fargo's unemployment rate fell by nearly 14 percent year over year. 14 percent was then subtracted from its Nov. 2011 unemployment rate.) The cities on this list are the 10 with the lowest resultant figures. (Above: Employees work at Citigroup's offices in Sioux Falls, S.D., in this 2007 file photo.)
