The verdict

Jasper County has a nationally busy FEMA history: 24 declarations, more than 66% of counties in this registry. But the state comparison tempers that reading: the total is 6% below the South Carolina county mean. FEMA's separate National Risk Index places the county in the riskiest 21%; that score models loss and vulnerability rather than counting declarations.

What does Jasper County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 113 paid claims, totaling $2.6M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $23.0K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

Start with the state benchmark: a South Carolina county averages 25.6 federal declaration records, while Jasper County has 24. The gap is 6% 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.

FEMA National Risk Index

This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 78.6/100 (Relatively Low). Expected Annual Loss is rated Relatively Low (roughly $28.8M in annualized losses). Social vulnerability reads Relatively High and community resilience Relatively Low, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Hurricane stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at roughly once every 3 years here, based on 121 historical events on record.

How often does each hazard strike Jasper 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
Hurricane Relatively High roughly once every 3 years
Earthquake Relatively Low roughly once every 307 years
Wildfire Relatively Low roughly once every 733 years
Heat Wave Relatively Low 9.6 modeled event-days per year
Coastal Flooding Relatively Low an average of 3.6 times per year
Lightning Relatively Low an average of 66 times per year
Drought Relatively Low 25 modeled event-days per year
Tornado Relatively Low roughly once every 3 years
Riverine Flooding Very Low roughly once every 3 years

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Jasper County's federal record, 63% of its declarations. Atlantic tropical systems run on a defined season, 1 June to 30 November, with most activity concentrated between August and October; Pacific and territorial basins run on their own calendars. A single named storm routinely produces one declaration number covering a long corridor of counties at once, well inland as well as on the coast, which is why an affected county's count can jump by several in one year without several separate events having occurred.

One practical distinction matters when reading these records: a tropical declaration usually bundles wind, storm surge and inland rainfall flooding under a single incident, but the insurance behind them is split. Wind damage falls to property insurers, while flood and surge damage is covered only under a separate National Flood Insurance Program policy. That is why a county can show heavy declaration activity and a comparatively small NFIP claims record, or the reverse.

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: Hurricane

Hurricane exposure in the model bundles the three ways a tropical system does harm, which arrive on different timescales and are insured differently: wind, storm surge on the coast, and rainfall flooding that can reach far inland well after landfall.

For Jasper County the two measures on this page point the same way: Hurricane is the county's highest-rated modeled hazard (Relatively High), and Hurricane declarations also lead its federal record. Where the model and the declaration history agree, the reading is comparatively straightforward, the hazard is both expected and repeatedly realised.

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

Jasper County's closest FEMA peer: Coconino County, AZ

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