The verdict

Start with the local benchmark for Gem County: 7 FEMA declaration records are 16% below the Idaho county mean, even though the count is higher than 4% of counties in the national registry. On FEMA's distinct National Risk Index model, which combines expected loss with vulnerability and resilience, the county ranks safer than 34%.

What does Gem County's hazard record show?

FEMA National Risk Index

FEMA's data shows an elevated National Risk Index composite of 34.4/100 for this county (Very Low rating). Expected Annual Loss comes in at Very Low (roughly $11.2M in annualized losses). Social vulnerability (Relatively Low) and community resilience (Relatively Low) both factor into how that raw exposure plays out on the ground. Among the 18 modeled hazards, Wildfire carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 65 years here.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 4 claims and $19.2K paid in total. PlainHazard calls 1-49 claims a light registry record, a label for this dataset rather than a finding that flood exposure is low. A short claims history can also reflect insurance take-up, the period covered, or losses that were never insured.

Start with the state benchmark: a Idaho county averages 8.3 federal declaration records, while Gem County has 7. The gap is 16% below that mean. Fewer entries indicate a quieter history of recorded federal actions, not immunity from a hazard and not a prediction about what happens next.

How often does each hazard strike Gem County?

FEMA's National Risk Index models a historical event count and an annualized frequency for each hazard type. Most hazards are expressed as modeled occurrences per year; FEMA expresses drought and heat-wave frequency as event-days per year. These modeled frequencies are not forecasts.

Hazard NRI Risk Rating Recurrence
Wildfire Relatively Moderate roughly once every 65 years
Winter Weather Relatively Low an average of 12 times per year
Earthquake Very Low roughly once every 360 years
Avalanche Very Low roughly once every 30 years
Landslide Very Low roughly once every 2 years
Volcanic Activity Very Low roughly once every 5,000 years
Heat Wave Relatively Low 3.5 modeled event-days per year
Riverine Flooding Relatively Low roughly once every 3 years
Strong Wind Relatively Low roughly once every 3 years
Ice Storm Very Low roughly once every 28 years
Lightning Very Low an average of 21 times per year
Drought Very Low 13 modeled event-days per year
Cold Wave Very Low roughly once every 19 years
Tornado Very Low roughly once every 37 years
Hail Very Low roughly once every 4 years

What Biological declarations mean here

Biological is the most frequent declaration type on Gem County's record, 29% of its declarations. In practice this category is dominated by the COVID-19 declarations of 2020, which were issued across every US state and territory rather than in response to any local hazard event.

This has a direct consequence for how Gem County's number should be read. Because those declarations reached essentially every county in the country, they raise every county's total by a similar amount and tell you nothing about local hazard exposure. A county whose record is led by Biological declarations is, in most cases, a county with a genuinely quiet weather-hazard history, the pandemic records are simply the largest thing in an otherwise short list.

Declaration counts describe past federal action. They are a record of what was declared, not a forecast of future hazard probability.

The model's sharpest exposure here: Wildfire

Wildfire risk in the model reflects fuel, terrain, weather and how much development sits in the wildland-urban interface. It is one of the few hazards where the exposure is materially changed by land management and building choices, not only by where the county happens to be.

Worth noting for Gem County: the model and the federal record do NOT point at the same hazard. Wildfire carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Biological. That is not a contradiction, the two measure genuinely different things. Declarations record federal ACTION, which requires damage costly enough to exceed state and local capacity; the Risk Index models EXPECTED annual loss across all 18 hazards whether or not any declaration ever followed. A hazard can be the county's largest modeled exposure and never once have driven a declaration.

National Risk Index ratings are modeled estimates of expected annual loss, not predictions of what will happen in any given year.

Data-matched county comparisons

Gem County's closest FEMA peer: Conejos County, CO

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Gem County. Record similarity, not a safety rating.

How these peers are chosen

Cohort: Published U.S. county equivalents outside the source state or territory. Each metric keeps six ETL candidates; three unique destinations are shown after de-duplicating across axes. Declaration-volume ranking combines count and Major-disaster share and prefers a different leading incident type; Major-share ranks the Major fraction adjusted for volume; NRI ranks the modeled composite score only.
