The Workers’ Compensation Insurance Rating Bureau of California (WCIRB) released the WCIRB Geo Study 2024, which underscores regional differences in claim characteristics across California. A web-based interactive map allows you to quickly view key measures across regions.
The study’s key findings include the following:
– – Even after controlling for regional differences in wages and industry mix, indemnity claim frequency continues to be significantly higher than the statewide average in the LA Basin and significantly lower than the statewide average in Northern California. This relationship has been fairly consistent over time, although the magnitude of the difference has fluctuated.
– – The LA/Long Beach region has the highest claim frequency, more than 35% above the statewide average.
– – The Yuba City/Redding/Far North and Peninsula/Silicon Valley regions have the lowest claim frequency, more than20% below the statewide average.
– – Regional differences in indemnity claim severity are more muted than for claim frequency. The magnitude of the differences has been consistent over time, but the relative severities by region have fluctuated. The severity relativities shown are adjusted for classification mix.
– – The highest severity cost is in SLO/Santa Barbara, which is more than 10% above the statewide average.
– – The lowest severity costs are in the San Bernardino/West Riverside and Sacramento regions, around 6% below the statewide average.
– – After adjustment for industry mix, regions with lower indemnity frequency tend to have a higher share of large claims, and there is a significant amount of variation among regions.
– – Yuba City/Redding/Far North, Sonoma/Napa and Bay Area have shares of large claims that are above the statewide average.
– – San Bernardino/West Riverside, LA/Long Beach and San Gabriel Valley/Pasadena have shares of large claims that are below the statewide average.
– – There has been a slight increase in the statewide share of indemnity claims that include permanent disability from PY 2021 to PY 2022 at 18 months (RL 1), reversing the decreases since PY 2015
– – Southern California regions have higher shares of indemnity claims with permanent disability than Northern California regions. SLO/Santa Barbara, Tulare/Inyo and LA/Long Beach have the highest shares, with more than 28% of their indemnity claims having permanent disability.
– – Sacramento, Stockton/Modesto/Merced, Bay Area and Peninsula/Silicon Valley have the lowest shares, with less than 22% of their indemnity claims having permanent disability.
– – The share of indemnity claims that include permanent disability is more than 17% above the statewide average in LA/Long Beach and 15% below the statewide average in Ventura at 90 months.
– – Southern California regions were more likely to have an increase in the share of CT claims. San Bernardino/West Riverside and LA/Long Beach (16) have had the largest increases at more than 2%.
– – The statewide share of paid medical for medical-legal reports continued to increase and is at an all-time high for this regional study. The share increased in nearly all regions, but the magnitude varied by region.
– – Medical-legal reports account for a significantly greater share of paid medical in the LA Basin than in the rest of the state.
– – Santa Monica/San Fernando Valley, LA/Long Beach and San Gabriel Valley/Pasadena have the highest shares, more than 12%.
– – Yuba City/Redding/Far North has the lowest share, less than 6%.
– – The LA/Long Beach and Orange County regions had the highest share of litigated indemnity claims, at more than 12% above the statewide average.
– – The Yuba City/Redding/Far North and Sonoma/Napa regions had the lowest shares of litigated indemnity claims, at more than 17% below the statewide average.
