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 Marion County, the largest single contributor is Tornado, 47% of the life-safety total.

Marion County carries an expected under 1 natural hazard fatality-equivalents and $8.8M in building loss per year. Rank chips compare the 99 Iowa counties. Nationally, Marion County ranks 2023rd of 3,222 U.S. counties for life-safety loss, 2430th for life safety per 100k residents, 1665th for property loss, and 2197th for property loss per resident. Computed from census tract data covering every resident, independent of fire department boundaries.

Add fire mortality, cause, and loss

Natural hazard exposure is one half of the picture. The other half is what your departments run on: fire deaths and injuries, cause of ignition, dollar loss per incident. That comes from NERIS incident reporting, and it grows as departments serving Marion County enroll. Our Regional tier brings it together across your jurisdiction, with participating departments, alongside response time analytics, cross-department benchmarking, and coverage gap analysis.

What Drives the Loss

61%
18%
20%
Property (buildings): $8.8M (61.5%)
Life safety: $2.6M (18.2%)
Agriculture: $2.9M (20.3%)

Total expected annual loss: $14,246,802 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.

Agriculture is 20% of expected annual loss in Marion County, so total loss overstates property loss here. The property figure above counts building loss only.

Department Rankings

Fire and EMS departments serving Marion County. Click column headers to sort.

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 boundaries and station counts are self-reported through NERIS Public and may not reflect current service areas. Population and Life-Safety Loss reflect each department's full jurisdiction. County-level risk metrics are computed from census tract data and are not affected by boundary accuracy. See full methodology.
