Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Jackson County is led by Riverine Flooding (about $6.7M Expected Annual Loss, Historical Loss Ratio Relatively High), while Landslide carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Jackson County's hazard record show?

FEMA National Risk Index

FEMA's data shows an elevated National Risk Index composite of 36.1/100 for this county (Very Low rating). Expected Annual Loss comes in at Very Low (roughly $14.1M in annualized losses). Social vulnerability (Very Low) and community resilience (Relatively High) both factor into how that raw exposure plays out on the ground. Among the 18 modeled hazards, Landslide carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 1 years here.

Reading the federal records together

This county has a small entry in FEMA's NFIP paid-claims table: 42 claims and $383.8K 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.

The declaration register points in the busier direction. Jackson County's 21 federal records stand 9% above the Iowa county mean of 19.3. That comparison describes how often federal action was recorded, including any Major Disaster, Emergency, and Fire Management entries shown on this page; it does not convert the count into future probability.

How often does each hazard strike Jackson 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
Landslide Relatively Moderate roughly once every 1 years
Hail Relatively Moderate an average of 4.1 times per year
Drought Relatively Moderate 11 modeled event-days per year
Strong Wind Relatively Moderate an average of 6 times per year
Cold Wave Relatively Low an average of 7.3 times per year
Tornado Relatively Low roughly once every 2 years
Riverine Flooding Relatively Low an average of 1.4 times per year
Ice Storm Relatively Low roughly once every 2 years

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Jackson County's record, 48% of its declarations. In FEMA's vocabulary this covers convective weather: thunderstorm straight-line winds, large hail, and the multi-day outbreaks that often carry embedded tornadoes. Activity is heaviest in spring and summer, though the season varies by region.

These events behave differently from a hurricane on paper. Damage tends to be distributed along a storm track rather than concentrated on a coastline, and a declaration typically follows an outbreak that crossed several counties over a few days, not a single point of impact. Because the qualifying threshold is the cost of uninsured public and individual losses rather than storm intensity, two similar storms can produce a declaration in one year and none in another.

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: Landslide

Landslide risk is a function of slope, soil and water, so it is usually a SECOND-ORDER hazard: it is triggered by the rainfall, snowmelt, wildfire burn scars or seismic shaking that came first. That is why a county can carry high landslide exposure whose realized damage is recorded under a flood or storm declaration instead.

Worth noting for Jackson County: the model and the federal record do NOT point at the same hazard. Landslide carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Severe Storm. 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

Jackson County's closest FEMA peer: Freeborn County, MN

Comparisons use published FEMA declaration fields plus the National Risk Index composite for Jackson 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.
