Natural Hazard Loss Profile
Expected annual loss across the 18 natural hazards in FEMA's National Risk Index. Life safety is expressed in fatality-equivalents, combining expected deaths and injuries. Property loss counts building damage only, not agriculture.
These figures cover natural hazards only. Structure fire, EMS, and motor vehicle incidents are not in the National Risk Index, so this is not an all-cause life safety measure. For Arizona, the largest single contributor is Heat Wave, 86% of the life-safety total.
Arizona carries an expected 100 natural hazard fatality-equivalents and $2.2B in building loss per year. Ranks compare the 50 states. Computed from census tract data covering every resident, independent of fire department boundaries.
Add fire mortality, cause, and loss
Natural hazard exposure is only part of the risk. Fire deaths and injuries, cause of ignition, and dollar loss per incident come from NERIS incident reporting, which grows as departments in Arizona enroll. Our Regional tier adds that data for the departments your jurisdiction sponsors, next to public risk and NERIS adoption for every department in Arizona.

Total expected annual loss: $3,607,876,833 per year. Life safety is shown here in dollars, at FEMA's $13.7M value of statistical life, so the three shares sum to the total.
Hazards Ranked Two Ways
The hazard that threatens people is often not the hazard that destroys buildings. Both columns cover the same 18 hazards over the same year.

Fire Service Profile
Department composition covers the 196 departments registered in NERIS Public for Arizona. Departments that have not registered are not counted. Station coverage divides census population by registered stations; department service areas overlap, so their populations are not summed.

NRI Rating is from FEMA's National Risk Index, which measures community risk across 18 natural hazards using expected annual losses, social vulnerability, and community resilience. Life-Safety Loss uses FEMA's Value of Statistical Life ($13.7M per expected fatality) to estimate annual risk to human life.
Department and station counts are derived from boundaries self-reported through NERIS Public and may not reflect current service areas. A department serving several counties is counted in each, so the Departments column adds up to more than the statewide department total. Risk metrics are computed from census tract data and are not affected by boundary accuracy. See full methodology.
