After hitting its lowest point in over four years, Dickson County’s unemployment rate went up a point in December. The Tennessee Department of Labor and Workforce Development reports Dickson County’s unemployment rate rose to 7.3 percent in December, with 1,830 residents receiving benefits. That is up from the 6.3 percent reported in November, the county’s lowest rate since April 2008, but well below the 8.8 percent reported in 2011. The department says 93 of Tennessee’s 95 counties saw increases in December, mostly due to declines in seasonal employment. Tennessee’s monthly county rates are not adjusted for seasonal employment. The state’s unemployment rate, which is adjusted for seasonal employment, remained unchanged from November at 7.6 percent. Williamson County had the state’s lowest rate at 5 percent while Scott County remains the highest at 16.8 percent. Thirty-two Tennessee counties are still reporting double-digit unemployment.
