RIVERSIDE, Calif. -

A seasonal dip in public sector payrolls and losses in a number of local industries pushed the unemployment rate in Riverside County back above 10 percent, state officials reported today.

The county's non-seasonally adjusted jobless rate in June, based on preliminary estimates, was 10.2 percent, compared with 9.2 percent in May, according to the California Employment Development Department.

The rate was 2.5 percentage points below the level of June 2012, when unemployment stood at 12.7 percent.

According to figures, the civilian labor force last month numbered 934,500 people, with 95,300 out of work.

The unincorporated community of Cabazon had the highest unemployment rate countywide, at 25.8 percent, followed by Mecca at 20.6 percent and Homeland at 20.2 percent, according to the EDD.

The combined unemployment rate for Riverside and San Bernardino countiesin June also was 10.2 percent, up from 9.3 percent the prior month.

Bi-county data indicated a sharp drop in government payrolls last month, mainly in local education, as teachers, aides, cafeteria workers and others employed at schools throughout the region went on summer recess. Almost 3,000 public sector workers were counted as unemployed.

The financial services, health services, construction, manufacturing, leisure and hospitality and uncategorized sectors altogether shed approximately 5,000 positions.

Only three sectors expanded -- farming, retail trade and professional services, which altogether added 4,500 jobs, the largest part of which was in agriculture.

The state's non-seasonally-adjusted jobless rate in June was 8.8 percent, according to the EDD.
