Underreporting and selection bias of serious road traffic injuries in auto insurance claims and police reports in British Columbia, Canada
We found gaps in how motor-vehicle traffic injuries are captured across British Columbia's administrative datasets, with insurance claims recording the highest percentage of injuries (95.7% for drivers, 83.3% for cyclists, 76.5% for pedestrians), yet substantial proportions of hospitalized individuals missing from both insurance and police records, particularly among vulnerable road users and low-income populations—potentially perpetuating inequities when these incomplete datasets inform safety investment priorities.
