How we estimate this
We start from the state's average liability, collision and comprehensive premiums published by the NAIC, then apply a location factor (population density and commute time from the Census ACS, weather hazard scores from FEMA's National Risk Index), a vehicle factor (HLDI insurance-loss data where available, otherwise vehicle segment), and a driver-profile multiplier.
