NORTH BAY -- Sonoma, Mendocino and Lake counties had a total of 2,630 more jobs in June than a year before, but that was offset by 3,200 fewer jobs in Solano and Napa counties over that 12-month period, according to preliminary state figures released this morning.

Unemployment rates in Lake, Marin, Mendocino, Napa, Solano and Sonoma counties in June increased from revised May estimates as the summer construction season picked up and schools let out for vacation, according to the state Employment Development Department. While the year-over-year North Bay and statewide jobless rates were largely unchanged in June, Sonoma County's four-10ths of a point decrease bested the nation's three-10ths of a point drop.

Sonoma County had 1,800 more jobs last month than in June 2010, the eighth straight month of such annual gains. Net gains came from the 700 more in construction; 500 each in professional and business services, education and health services, and leisure and hospitality; and 100 in government, taking into account 800 fewer positions from May to June.

Industries in the county that lost positions over the year were manufacturing (minus 200), despite 200 more in high-tech manufacturing; trade, transportation and utilities (-200), because of 700 fewer in retail trade; and 100 less in financial activities.

Solano County had a net loss of 3,000 jobs over the 12 months ending in June, led by 900 fewer in professional and business services, 700 in government and 500 each in education and health services and in trade, transportation and utilities.

There were 200 fewer jobs in Napa County last month than a year before, led by 500 fewer in government, 200 each in construction and manufacturing and 100 each in trade and professional and business services. Those losses offset gains of 400 in leisure and hospitality, 300 in farming and 200 in education and health services.

Current industry employment figures aren't available for Marin County, but what figures are available suggest job growth there too. Marin's unemployment rate decreased two-10ths of a percentage point in June from a year before. Over the 12 months, the total civilian workforce in the county increased by 200, and the roll of those receiving unemployment insurance payments decreased by 300.
