WCIRB Releases 2018 Geo Study with New Interactive Map

Today, the WCIRB released the 2018 WCIRB Geo Study (Study). The study underscores the differences in costs of claims among California regions with the addition of a new web-based interactive map.

The Study’s key findings are:

  • After controlling for regional differences in wages and industrial mix, indemnity claim frequency is significantly higher (% above average) in the Los Angeles Basin and significantly lower in the San Francisco Bay Area.
  • Differences in regional indemnity claim frequency range from more than 32% higher than average in the Los Angeles/Long Beach region to almost 25% lower than average in the San Francisco Peninsula/Silicon Valley region. The difference between these regions grew from 2015 to 2016.
  • Pharmaceutical costs throughout the state have dropped over the last several years with the largest reductions occurring in Southern California.
  • Both medical legal costs and paid allocated loss adjustment expenses (ALAE) are significantly higher in the Bakersfield and Los Angeles Basin regions than in the remainder of the state.
  • The median paid ALAE on permanent disability claims increased more than 9% from 2015 to 2016. The average increased more than 7%.
