The verdict

Brown County has a nationally busy FEMA history: 17 declarations, more than 32% of counties in this registry. But the state comparison tempers that reading: the total is 1% below the Indiana 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 Brown County is led by Riverine Flooding (about $4.2M Expected Annual Loss, Historical Loss Ratio Relatively Low), while Ice Storm carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Brown County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 160 paid claims, totaling $5.0M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $31.4K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

Start with the state benchmark: a Indiana county averages 17.1 federal declaration records, while Brown County has 17. The gap is 1% 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's FEMA National Risk Index composite lands at 19.7/100 (Very Low), a modest reading against the rest of the country. Expected Annual Loss is rated Very Low (roughly $6.8M in annualized losses), tempered or compounded by a Relatively Moderate social-vulnerability score and Relatively Moderate community-resilience score. Among the 18 modeled hazards, Ice Storm carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 2 years here, based on 42 historical events on record.

How often does each hazard strike Brown 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 Moderate roughly once every 2 years
Landslide Very Low roughly once every 1 years
Tornado Relatively Low roughly once every 4 years
Strong Wind Relatively Low an average of 5 times per year
Earthquake Very Low roughly once every 552 years
Winter Weather Relatively Low an average of 8.5 times per year
Riverine Flooding Relatively Low roughly once every 1 years
Heat Wave Very Low 5.4 modeled event-days per year
Hail Very Low an average of 4.1 times per year

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Brown County's record, 47% 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 Brown County: the model and the federal record do NOT point at the same hazard. Ice Storm carries the highest modeled rating (Relatively Moderate), 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

Brown County's closest FEMA peer: Wright County, MN

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