San Diego’s unemployment rate fell to 8.6 percent in September from a revised 9 percent in August, the lowest since January 2009, and below the 9.9 percent rate in September 2011, according to the state’s Employment Development Department.

The local unemployment rate was below that of California’s adjusted unemployment rate of 10.2 percent, but above the nation’s jobless rate of 7.6 percent for the same month.

According to the EDD, there were nearly 135,000 unemployed people in the county last month, down from 157,500 in September 2011. People who stop looking for work or who are working part-time are not counted as unemployed.

The government sector, led by teachers and other classified workers returning to their school jobs, resulted in 6,400 added jobs in the past month. However, much of that gain was offset by the loss of 5,400 seasonal jobs in the leisure and hospitality sector.

The region had a net gain of 200 jobs in the past month, the report said. Over 12 months, the region had a net gain of 28,000 nonfarm jobs, an increase of 2.3 percent from the prior year’s September numbers.

The largest contributor to the full year increase came from the professional and business services sector which added 9,200 jobs, led by the subgroup of administrative and support service that generated 7,100 of that total.

Eight other job sectors added jobs, with the most notable being leisure and hospitality, up by 6,300; educational and health services, up 5,600; and trade, transportation and utilities, up 3,200.

Only one sector showed a net loss over the 12 months: manufacturing, which was down by 1,900 jobs. Mining and logging was flat from a year ago.
