It is a consistent sample, not a census; rates are comparable across periods and geographies but are not national totals. Rates are per 1,000 insured carriers domiciled in the state and are not adjusted for state size beyond that denominator.
Facility counts are derived from the EPA Facility Registry Service, a registry of environmentally permitted sites rather than a census of shippers.
