The verdict

Fairfield County has a nationally busy FEMA history: 13 declarations, more than 17% of counties in this registry. But the state comparison tempers that reading: the total is 11% below the Ohio county mean. FEMA's separate National Risk Index places the county in the riskiest 27%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Fairfield County is led by Riverine Flooding (about $26.6M Expected Annual Loss, Historical Loss Ratio Relatively Low), while Ice Storm carries the highest National Risk Index rating (Relatively High). EAL and risk score use different inputs; they need not agree.

What does Fairfield County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 299 paid claims, totaling $2.8M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $9.5K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

Start with the state benchmark: a Ohio county averages 14.6 federal declaration records, while Fairfield County has 13. The gap is 11% 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 carries a high composite score on FEMA's National Risk Index, 72.6/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $39.0M in annualized losses), and a Very Low social-vulnerability profile combined with Very High community resilience shapes how much of that raw exposure becomes realized harm. Of the 18 hazards FEMA models, Ice Storm stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at roughly once every 1 years here, based on 58 historical events on record.

Declaration frequency

Nationally, Fairfield County's 13 FEMA records form a high-volume history; within Ohio, however, the count is 11% below the county mean. 8 entries carry the Major Disaster classification. The largest incident group is Severe Storm, appearing 7 times. The full 52-year record averages 0.3 declarations annually. A DR label alone does not say whether Individual Assistance, Public Assistance, or both followed.

How often does each hazard strike Fairfield 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
Ice Storm Relatively High roughly once every 1 years
Landslide Relatively Low roughly once every 5 years
Hail Relatively Moderate an average of 2.8 times per year
Lightning Relatively High an average of 46 times per year
Riverine Flooding Relatively Moderate an average of 1.9 times per year
Winter Weather Relatively Moderate an average of 12 times per year
Heat Wave Relatively Moderate 4.1 modeled event-days per year
Drought Relatively Moderate 3.7 modeled event-days per year
Strong Wind Relatively Moderate an average of 1.5 times per year
Tornado Relatively Moderate roughly once every 5 years

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Fairfield County's record, 54% 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: Ice Storm

Ice storms load power lines and tree limbs with accumulating freezing rain until they fail. The characteristic cost is infrastructure and multi-day power loss across a wide area rather than structural damage to buildings, which is why their consequences often outlast the weather that caused them.

Worth noting for Fairfield County: the model and the federal record do NOT point at the same hazard. Ice Storm carries the highest modeled rating (Relatively High), 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

Fairfield County's closest FEMA peer: Lowndes County, GA

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

On social vulnerability the county rates Very Low; on community resilience, Very High. The Expected Annual Loss (EAL) score is Relatively Low, representing $39.0M in annualized losses.
Which natural hazard poses the greatest risk to Fairfield County?
Based on FEMA NRI data, the highest-risk natural hazard in Fairfield County as of the latest release is Ice Storm (risk rating: Relatively High). Other significant hazards include Landslide (Relatively Low) and Hail (Relatively Moderate). FEMA's modeled event frequency puts ice storm here at roughly once every 1 years, drawn from 58 historical events on record.

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 Fairfield County

Against a Ohio county mean of 15 declarations, Fairfield County, OH records 13, or 11% fewer. PlainHazard classifies that historical total as high activity.

  • Major Disaster is the largest group (8 of 13) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Ohio overview
  • Nationally the county exceeds 17% of recorded county totals, but its own Ohio benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
  • Use the data guide to separate this mid-volume insurance-claims file from declaration counts and modeled NRI risk. Disaster-data guide
