Newly released county non-seasonally adjusted unemployment rates for April 2012 show the rate decreased in 84 counties, increased in five counties, and remained the same in six counties.

Hamilton County was 7.0 percent, down from 7.3 percent, while Knox County had the state's lowest major metropolitan rate of 5.8 percent, up from 5.6 percent in March.

Davidson County was 6.5 percent, down from 6.6 percent in the previous month, and Shelby County was 8.3 percent, down from the March unemployment rate of 9.1 percent.  

The state unemployment rate is seasonally adjusted while the county unemployment rates are not. Seasonal adjustment is a statistical technique that eliminates the influences of weather, holidays, the opening and closing of schools, and other recurring seasonal events from economic time series.
