According to the most recent BLS press release on state unemployment:
Colorado's seasonally-adjusted unemployment rate was down slightly in December, dropping year over year from 7.9 percent during December 2011 to 7.6 percent during December 2012. The Colorado rate fell from November to December this year, dropping very slightly from 7.7 to 7.6 percent.
Nevada and Rhode Island recorded the highest unemployment rates among the states in December, 10.2 percent each. North Dakota again registered the lowest jobless rate, 3.2 percent. In total, 25 states reported jobless rates significantly lower than the U.S. figure of 7.8 percent, 8 states had measurably higher rates, and 17 states and the District of Columbia had rates that were not appreciably different from that of the nation.
The national unemployment rate fell by much more than it did in Colorado, falling from 8.5 percent to 7.8 percent from December 2011 to December 2012. The rate was flat at 7.8 percent from November to December.
