San Diego’s unemployment rate increased to 6.1 percent in June, up from May’s 5.8 percent despite the area adding a net of 9,700 jobs to county payrolls.

California’s unemployment came in at a seasonably adjusted 7.4 percent, while the national rate for June was 6.3 percent.

According to the state Employment Development Department, 3,900 people in the county were added to the unemployment rolls, bringing the total to 96,500. The uptick has occurred every year since 1990, and most likely is caused by high school and college graduates entering the workforce.

As for the job gains during the month, as has been the case for most of the year, leisure and hospitality contributed the most with 3,000. Professional and business services, which includes temporary employment, added 2,400 jobs; and the segment that includes retail trade added 1,200 jobs.

Every sector showed net gains except for educational and health services and mining and logging which remained unchanged.

Over the 12 months from June 2013, the region’s nonfarm employment increased by 34,600 jobs, or 2.6 percent.

The two largest job segments contributing to gains were professional and business services, up 6,900; and educational and health services, up 6,700.
