NORTH BAY -- The jobless rate decreased month over month in all North Bay counties in April, though still above 2009 rates for the same period, according to figures released by the Employment Development Department today.

The unemployment rate in Sonoma County was 10.6 percent, down from 11.4 percent in March and up from 9.1 percent in April 2009.

From last month, 300 jobs were added each in leisure and hospitality as well as educational and health services.

In Napa County the rate was 10.0 percent, down from 10.8 percent in March and up from 8.1 percent last April.

Marin County had the second-lowest unemployment rate in the state at 8.3 percent, down from 8.9 percent last month and up from 7.3 percent in April 2009. Industry-specific numbers were not available.

Solano County had a drop in joblessness to 12.2 percent from 13.0 percent in March. Last April the rate was 10.0 percent, with the increase due mostly to 1,000 jobs lost in construction and 1,100 more in government. From last month, 600 jobs were added in the leisure and hospitality sector.
