Today, the Workers’ Compensation Insurance Rating Bureau of California (WCIRB) released the 2022 WCIRB Geo Study, which underscores regional differences in claim characteristics across California. The web-based interactive map allows you to quickly view key measures across regions.

The study, related exhibits and mapping of nine-digit zip codes to the regions referenced in the study are available in the Research section of the WCIRB website and at the following link:

• 2022 WCIRB Geo Study

The study’s key findings include the following:

• Even after controlling for regional differences in wages and industry mix, indemnity claim frequency is significantly higher in the Los Angeles (LA) Basin and significantly lower in the San Francisco Bay Area.
• During the pandemic, indemnity claim frequency increased significantly in Orange County relative to the rest of the state and decreased significantly in Ventura and Santa Monica/San Fernando Valley.
• The share of cumulative trauma claims as a percent of all claims increased for all regions during the pandemic. The increase was largest in San Bernardino/West Riverside and LA/Long Beach, which also have high relative frequency of indemnity claims. It was also relatively high in the Bay Area and Sonoma/Napa, which saw decreases in the relative frequency of indemnity claims.
