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 Ontonagon County, the largest single contributor is Cold Wave, 76% of the life-safety total.
Ontonagon County carries an expected under 1 natural hazard fatality-equivalents and $1.4M in building loss per year. Rank chips compare the 83 Michigan counties. Nationally, Ontonagon County ranks 2861st of 3,222 U.S. counties for life-safety loss, 1552nd for life safety per 100k residents, 3044th for property loss, and 2351st for property loss per resident. Computed from census tract data covering every resident, independent of fire department boundaries.

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.
