Nevada natural hazard risk by county

Nevada has about $1.37 billion in modeled expected annual loss across 17 counties. The state accounts for 0.9% of the national modeled loss total. Its total ranks #34 among 56 state-level entries by modeled loss. FEMA published these 17 county estimates in its December 2025 National Risk Index. The modeled $1.37 billion annual average does not predict loss in any one year.

Reading the Nevada county map

The map groups 17 county estimates into five within-state loss classes. Each boundary follows the county geography, while the fill represents modeled dollars per year. The class breaks are calculated from Nevada county values, so a matching shade on another state page need not represent the same amount. Grey marks unmatched geography or an unavailable estimate. Outlined counties link to the detailed profiles available in this release; counties without profiles still contribute to the state totals.

Together, the three largest estimates account for 84.7% of Nevada modeled annual loss. Their combined population represents 90.4% of the state source population. Comparing these two shares helps distinguish the concentration of modeled dollars from the concentration of residents. Neither share identifies the exposure of an individual address, and the map does not show the location of damage within a county.

County totals beside population

Clark County, NV combines about $812.6 million in modeled annual loss with 2,260,510 recorded residents. Dividing those figures gives about $359 per resident, compared with $443 statewide.
