The verdict
Hancock County has a nationally busy FEMA history: 15 declarations, more than 23% of counties in this registry. But the state comparison tempers that reading: the total is 22% below the Iowa county mean. FEMA's separate National Risk Index places the county safer than 29%; that score models loss and vulnerability rather than counting declarations.

Hancock County's FEMA Risk Index score
What does Hancock County's hazard record show?
FEMA National Risk Index
This county's FEMA National Risk Index composite lands at 28.8/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $11.2M in annualized losses), tempered or compounded by a Very Low social-vulnerability score and Very High community-resilience score. Of the 18 hazards FEMA models, Drought stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at 18 modeled event-days per year here, based on 581 historical events on record.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 3 claims and $8.0K 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 Iowa county averages 19.3 federal declaration records, while Hancock County has 15. The gap is 22% 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 Hancock 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 |
|---|---|---|
| Drought | Relatively High | 18 modeled event-days per year |
| Winter Weather | Relatively Moderate | an average of 20 times per year |
| Cold Wave | Relatively Moderate | an average of 11 times per year |
| Hail | Relatively Low | an average of 4.6 times per year |
| Tornado | Relatively Low | roughly once every 2 years |
| Strong Wind | Relatively Low | an average of 3.8 times per year |
| Ice Storm | Very Low | roughly once every 2 years |
| Landslide | Very Low | roughly once every 15 years |
| Riverine Flooding | Very Low | an average of 1.4 times per year |
| Lightning | Very Low | an average of 42 times per year |
| Earthquake | Very Low | roughly once every 2,123 years |
| Heat Wave | Very Low | 3.5 modeled event-days per year |
| Wildfire | Very Low | roughly once every 17,382 years |

What Flood declarations mean here
Flood is the most frequent declaration type on Hancock County's record, 33% of its declarations. Federal flood declarations cover two mechanisms that behave very differently: riverine flooding, which builds over days as a watershed drains and is usually forecast well in advance, and flash flooding, which can arrive in under an hour from rainfall that fell somewhere upstream.
Flood is also the one hazard class where a second federal dataset exists for the same events. The National Flood Insurance Program records what was actually paid on insured losses, so it measures a narrower thing than the declaration count: uninsured damage, and flooding outside mapped special flood hazard areas, never enters it. Reading the two together is more informative than either alone.
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: Drought
Drought is the slowest of the modeled hazards and the least visible: it does its damage to agriculture, water supply and soil over seasons rather than hours, so it rarely produces the kind of single-day damage that drives a disaster declaration. FEMA scores it in event-days per year rather than discrete events for exactly that reason.
Worth noting for Hancock County: the model and the federal record do NOT point at the same hazard. Drought carries the highest modeled rating (Relatively High), while the county's declaration history is led by Flood. 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.
