The unemployment rate in Orange County moved up slightly in October despite an increase in local jobs.

OC employers added 13,900 jobs last month, for a total of 1,559,700, according to the state Employment Development Department. The total reflects a year-over-year growth of 2.7%, or by 41,000 jobs.

OC’s unemployment rate inched up to 4.3% from September’s 4%. It’s below the year-earlier reading of 5.2%.

California’s unemployment rate, not seasonally adjusted, was 5.7%, versus 5.5% in September and 7% a year earlier.

Nationwide, the rate was 4.8%, down from September’s 4.9% and 5.5% a year earlier.

Seasonally adjusted figures, which are more widely reported, show that California’s jobless rate was 5.8% and nationwide, 5%.

The number of government jobs in OC increased by 6,700, largely due to “continuing seasonal gains in local government education following the summer recess,” according to the department. OC has a total of 159,400 government jobs, up 2.9% over the past year.
