This
report provides a collection of actuarial metrics to compare differences across geographic regions within NCCI’s three largest jurisdictions by population—Florida, Illinois, and Texas. These metrics provide insight into regional differences in frequency, severity, and overall costs across these jurisdictions. Every state has its own story, and by examining these metrics, we expand on the story.
Key Insights
- Regional differences in frequency, severity, and overall costs exist within NCCI’s three largest states by population: Florida, Illinois, and Texas.
- Neither frequency nor severity were identified as consistent drivers of the loss ratio relativities across regions.
- Differences in results were found for cohorts of policies that span single versus multiple regions within a state.
Analysis Summary
The three primary data sources underlying this report are Policy Data, the Unit Statistical Plan, and the Medical Data Call. Exposure and losses are not reported for each individual business location in these data sources; therefore, estimation was necessary to allocate total policy experience across business locations.
Actuarial metrics are based on data from Policy Years 2021–2023. All losses are incurred at first report and are limited to $500K.
A downloadable file accompanies the report for a deeper dive into the data.
Conclusion
The regional differences in frequency, severity, and overall costs expand the individual state story for Florida, Illinois, and Texas. Looking forward, NCCI is considering periodic updates to this analysis. As future data collection expands and evolves, NCCI may revisit opportunities to research additional states.
