The verdict
McCormick County has a nationally busy FEMA history: 21 declarations, more than 52% of counties in this registry. But the state comparison tempers that reading: the total is 18% below the South Carolina county mean. FEMA's separate National Risk Index places the county safer than 10%; that score models loss and vulnerability rather than counting declarations.

McCormick County's FEMA Risk Index score
Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for McCormick County is led by Riverine Flooding (about $1.2M Expected Annual Loss, Historical Loss Ratio Relatively Moderate), while Hurricane carries the highest National Risk Index rating (Relatively Low). EAL and risk score use different inputs; they need not agree.

What does McCormick County's hazard record show?
FEMA National Risk Index
FEMA's National Risk Index places this county in the low end of the national distribution, composite score 9.5/100 (Very Low). Expected Annual Loss is rated Very Low (roughly $2.8M in annualized losses). Two modifiers shape how that exposure becomes real-world harm here: social vulnerability (Very High) and community resilience (Very Low). Even the county's top-rated hazard, Hurricane, only reaches Relatively Low on FEMA's scale, none of the 18 modeled hazards stand out here. FEMA's modeled frequency puts that hazard at roughly once every 16 years here, based on 22 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 2 claims and $88.1K 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 South Carolina county averages 25.6 federal declaration records, while McCormick County has 21. The gap is 18% 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 McCormick 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 Low | roughly once every 16 years |
| Ice Storm | Relatively Low | an average of 1.1 times per year |
| Earthquake | Very Low | roughly once every 367 years |
| Tornado | Relatively Low | roughly once every 4 years |
| Wildfire | Very Low | roughly once every 1,516 years |
| Heat Wave | Very Low | 3.3 modeled event-days per year |
| Landslide | Very Low | roughly once every 3 years |
| Hail | Very Low | an average of 3.5 times per year |
| Cold Wave | Relatively Low | roughly once every 5 years |
| Strong Wind | Relatively Low | an average of 3.7 times per year |
| Lightning | Very Low | an average of 56 times per year |

What Hurricane declarations mean here
Hurricane is the most frequent declaration type on McCormick County's federal record, 48% 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 McCormick County the two measures on this page point the same way: Hurricane is the county's highest-rated modeled hazard (Relatively Low), 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.
