NORTH BAY -- High unemployment rates across the North Bay in July either were virtually the same as in June or a year before or barely edged upward, as private-sector job gains were offset by fewer government jobs, according to state figures released this morning.

Sonoma County's unemployment rate was 10.3 percent, up from 10.1 percent in June but below the 10.7 percent rate in July 2010, according to the state Employment Development Department.

Solano County's rate last month was 12.2 percent, up from 12 percent in June and above the year-ago rate of 12.1 percent.

Napa County remained flat, at 9.2 percent for two consecutive months, which is unchanged from a year ago.

Marin County retained the lowest jobless rate in the North Bay and in California at 8.1 percent in July, compared with 8 percent in June.

Mendocino County's jobless rate increased to 11.3 percent from 10.9 percent in May and up from 11.1 percent a yea ago.

Lake County continued to have one of the highest jobless rates in the state, at 17.5 percent last month. The rate rose from 17.3 percent in June and unchanged from a year ago.

In Sonoma County, construction had 800 more jobs in June than a year ago. Leisure and hospitality and professional services sectors each gained 500 jobs.

But government shed 700 jobs over the year, and from June to July it lost 4,700 jobs.

Likewise in Napa County, education and health services gained 500 jobs over the year, and leisure and hospitality added 400 in that time frame.

Government in the county shed 600 jobs over the year and had 800 fewer than in May.

Industry specifics aren't available for Marin, which is part of a three-county West Bay region that includes San Francisco and San Mateo counties. In those three counties, though, the trend was similar -- government lost 3,100 jobs as local and state schools scaled back operations for the summer.

Solano County had no net gain in employment over the year, as the public sector was joined by education and health services and professional services in each having losses of 700 jobs.

The same was true in Mendocino and Lake counties.  Mendocino cut 1,410 government jobs from June to July, while Lake County lost 460 public-sector jobs. Farming also lost 330 jobs.
