Sonoma County’s unemployment rate in December remained unchanged from the previous month at 4.2 percent, the state Employment Development Department reported Friday.

A year ago, the unemployment rate was 5 percent in the county. Since then, the county has added 6,200 jobs.

“We’ve improved since last December,” said Janet Klaven, an EDD labor market consultant based in Santa Rosa. “There are more jobs out there.”

The county’s jobless rate compares with 5.8 percent for California and 5 percent for the nation.

From November to December, the county added 300 non-farm jobs and another 100 jobs in agriculture.

The monthly gains included 600 new jobs in retail trade and 400 in leisure and hospitality. In contrast, construction jobs fell by 500.

Over the last year, the county has added 5,800 non-farm jobs and 400 jobs in agriculture. They include 2,200 in business and professional service, 1,100 in construction, 1,000 in health care and 800 for retail trade.

The main area of decline was in manufacturing. In the past year, the nondurable goods sector shed 700 jobs, while durable goods lost 400 jobs.

December was the 40th consecutive month in which the construction sector reported more jobs than for the same month a year earlier. For the transportation, trade and utilities sector, it was the 64th consecutive month.

“It’s another month of good news,” said Ben Stone, executive director of the Sonoma County Economic Development Board.

To the delight of job seekers and the lament of human relation managers, Stone said, “We are in full recovery.”

With strong demand for workers, he said, “I would expect this year to see wages start to rise.”

Sonoma last month ranked sixth among the state’s 58 counties based on the lowest unemployment rates. Marin ranked second at 3.2 percent; with Napa 13th at 5.1 percent; Mendocino 24th at 5.9 percent and Lake 32nd at 7.3 percent.

San Mateo County ranked first at 3.1 percent.
