San Diego’s unemployment rate rose to 9.5 percent in March, compared with a revised 9.4 percent in February, according to the state’s Employment Development Department report April 20.

The rate for California for March was 11 percent, up from 10.9 percent in February, while the national rate was 8.4 percent, down from 8.4 percent.

The region gained a net of 2,900 nonfarm jobs during the past month, but a higher number of job seekers entering the labor force caused the jobless rate to rise.

Six sectors showed local job gains in March. Leisure and hospitality was up 2,800; government up 2,000; educational and health services up 900; construction up 500; and financial activities and other services, up 100 each.

The largest declines were in professional and business services, down 2,900 jobs; manufacturing, down 300; trade, transportation and utilities, down 200; and information, down 100.

In the past 12 months, the region gained a net of 6,700 nonfarm jobs, or a half percent, from March 2011, the EDD said.

The three biggest contributors to the increase came from educational and health services, up 3,700; trade, transportation and utilities (which includes retail trade), up 3,400; and leisure and hospitality, up 2,500.
