NORTH BAY -- Unemployment rates across the North Bay (see chart) in March either remained at the previous month's high levels or inched upward, but Sonoma County continued a four-month stretch of substantial year-over-year job growth, reaching 5,000 net new jobs last month, according to state estimates released today.
Most counties saw slight increases in their jobless rates, including Sonoma County. The uptick in jobless claims is an indication that the labor force is growing, as previously unemployed workers reenter the job market, according to the state Employment Development Department.
