New York experienced the only significant over-the-year increase in its unemployment rate (+0.8 percentage point).Colorado was not one of the states that reported decreases in the unemployment rate, year over year. The seasonally-adjusted unemployment rate in Colorado fell from 8.3 percent to 7.8 percent from July to August, and it fell from 8.1 percent to 7.8 percent from August 2011 to August 2012.
