San Diego’s unemployment rate rose to 10.2 percent in March from a revised 10.1 percent in February, but it was less than the 10.8 percent mark for the same month last year, according to an April 15 report from the state’s Employment Development Department.

The unadjusted jobless rate in March was 12.3 percent for California and 9.2 percent for the nation.

The jobless rate nudged up because nearly 1,500 newly unemployed people were added to the unemployment rolls during the past month.

The local region gained a net of 10,300 jobs during March, with the largest increases coming from the leisure and hospitality segment, which added 3,100 jobs. The next largest segments showing gains were professional and business services, with gains of 2,200 jobs; and educational and health services, up 1,700.

Manufacturing was the only sector registering a loss, down 400 jobs during the month.

For the full 12 months, the region had a net gain of 24,700 jobs, up 2 percent from March 2010. The biggest contributors to the gains were in professional and business services, up 12,900 jobs; educational and health services, up 4,900; and leisure and hospitality, up 4,800. Five sectors had net losses over the year led by construction, down 1,000 jobs; and manufacturing, down 700 jobs.
