Tennessee

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, separate from agriculture.

These figures cover natural hazards only. Structure fire, EMS, and motor vehicle incidents are not included in the National Risk Index and are not counted here, so this is not an all-cause life safety measure. For Tennessee, the largest single contributor is Cold Wave, 30% of the life-safety total.

Tennessee carries an expected 86 natural hazard fatality-equivalents and $1.8B in building loss per year. Ranks compare all 50 states plus DC and Puerto Rico. Computed from census tract data covering every resident, independent of fire department boundaries.

What Drives the Loss

Total expected annual loss: $3,004,305,920 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 637 departments registered in NERIS Public for Tennessee. Departments that have not registered are not counted. The mix is computed over the departments NERIS registers to Tennessee; departments based elsewhere that respond into it are counted in the total above but not in the mix. 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.
