Employment Practices Workers Comp Coverage Claims Management Workers Comp Pricing California workers compensation claim frequency increased 3% from 2010 to 2014 despite an 11% fall in claim frequency in most other states during that time, according to the California Workers’ Compensation Insurance Rating Bureau.

In a report released Thursday, Oakland, California-based WCIRB compared its comp claim frequency data with claim frequency in 35 states and the District of Columbia, where the National Council on Compensation Insurance Inc. acts as the workers comp ratemaker.

WCIRB said in the report that California workers have shifted toward more hazardous industries, such as construction and manufacturing, as those sectors have increased hiring in recent years.
