Tennessee’s unemployment rate for September was 4.7 percent, up 0.7 percent from August. State labor officials said the hike is due to an increase in the labor force because of 18,000 new job seekers last month. August to September gains were seasonal, with government jobs increasing by about 14,000. Administrative support and waste services, which are primarily temporary workers, increased by 2,500. Educational services increased by 2,400. Month-to-month declines included leisure and hospitality, manufacturing and retail trade.
