The verdict
Carroll County has a nationally busy FEMA history: 11 declarations, more than 12% of counties in this registry. But the state comparison tempers that reading: the total is 25% below the Ohio county mean. FEMA's separate National Risk Index places the county safer than 20%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?
FEMA's modeled annual dollar loss for Carroll County is led by Riverine Flooding (about $4.7M Expected Annual Loss, Historical Loss Ratio Relatively Low), while Landslide carries the highest National Risk Index rating (Relatively Low). EAL and risk score use different inputs; they need not agree.

What does Carroll County's hazard record show?
Declaration frequency
Nationally, Carroll County's 11 FEMA records form a high-volume history; within Ohio, however, the count is 25% below the county mean. 6 entries carry the Major Disaster classification. The largest incident group is Severe Storm, appearing 5 times. The full 43-year record averages 0.3 declarations annually. A DR label alone does not say whether Individual Assistance, Public Assistance, or both followed.
FEMA National Risk Index
This county's FEMA National Risk Index composite lands at 19.9/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $6.4M in annualized losses), tempered or compounded by a Relatively Moderate social-vulnerability score and Relatively Moderate community-resilience score. Even the county's top-rated hazard, Landslide, 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 1 years here.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 31 claims and $613.7K 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 Ohio county averages 14.6 federal declaration records, while Carroll County has 11. The gap is 25% 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 Carroll 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 Low | roughly once every 1 years |
| Lightning | Relatively Moderate | an average of 42 times per year |
| Hail | Relatively Low | an average of 4.2 times per year |
| Drought | Relatively Low | 2.2 modeled event-days per year |
| Riverine Flooding | Relatively Low | an average of 1.8 times per year |
| Hurricane | Very Low | roughly once every 141 years |
| Heat Wave | Very Low | 1.9 modeled event-days per year |
| Ice Storm | Relatively Low | roughly once every 3 years |
| Tornado | Relatively Low | roughly once every 6 years |
| Strong Wind | Relatively Low | an average of 2.4 times per year |
| Earthquake | Very Low | roughly once every 1,832 years |
| Winter Weather | Relatively Low | an average of 9.5 times per year |
| Wildfire | Very Low | roughly once every 11,627 years |
| Cold Wave | Very Low | an average of 3 times per year |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Carroll County's record, 45% 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 Carroll County: the model and the federal record do NOT point at the same hazard. Landslide carries the highest modeled rating (Relatively Low), 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 Sources & Methodology
Disaster declaration data comes from the FEMA OpenFEMA Disaster Declarations Summaries v2 API, which includes all federally declared disasters, emergencies, and fire management assistance grants.
Storm event data is sourced from the NOAA Storm Events Database (2015-2025), which tracks significant weather events including thunderstorms, tornadoes, floods, and winter storms.
Flood insurance data comes from the FEMA National Flood Insurance Program (NFIP) OpenFEMA claims dataset.
This data is provided for informational purposes only. FEMA disaster declarations represent federal response actions and may not capture all local emergencies or weather events.
What this means for Carroll County
Against a Ohio county mean of 15 declarations, Carroll County, OH records 11, or 25% fewer. PlainHazard classifies that historical total as high activity.
- Major Disaster is the largest group (6 of 11) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Ohio overview
- Nationally the county exceeds 12% of recorded county totals, but its own Ohio benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
- A short NFIP claims file cannot establish low flood exposure; the data guide explains the limits of each federal measure. Disaster-data guide
A below-average federal record is not a safety guarantee. Use National Weather Service alerts and local emergency-management notices for present conditions, not this historical comparison.
