The verdict

Union 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 12% below the Indiana county mean. FEMA's separate National Risk Index places the county safer than 5%; that score models loss and vulnerability rather than counting declarations.

Which hazard drives modeled loss here?

FEMA's modeled annual dollar loss for Union County is led by Riverine Flooding (about $1.7M Expected Annual Loss, Historical Loss Ratio Relatively High), while Strong Wind carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.

What does Union 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 5.2/100 (Very Low). Expected Annual Loss is rated Very Low (roughly $4.3M in annualized losses). Two modifiers shape how that exposure becomes real-world harm here: social vulnerability (Very Low) and community resilience (Relatively Low). Among the 18 modeled hazards, Strong Wind carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 3.1 times per year here, based on 118 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 $50.5K 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 Indiana county averages 17.1 federal declaration records, while Union County has 15. The gap is 12% 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 Union 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
Strong Wind Relatively Moderate an average of 3.1 times per year
Landslide Very Low roughly once every 18 years
Tornado Relatively Low roughly once every 8 years
Drought Very Low 1 modeled event-day per year
Earthquake Very Low roughly once every 578 years
Cold Wave Very Low an average of 4.2 times per year
Ice Storm Very Low an average of 1 time per year
Heat Wave Very Low 5.4 modeled event-days per year
Hail Very Low an average of 3.7 times per year
Hurricane Very Low roughly once every 174 years

What Severe Storm declarations mean here

Severe Storm is the most frequent declaration type on Union County's record, 53% 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: Strong Wind

Strong Wind covers damaging non-thunderstorm, non-tornadic wind, the kind produced by steep pressure gradients and downslope events. It is a broad, frequent, low-drama hazard: roofs, signage, power lines and high-profile vehicles, spread across a wide area rather than concentrated on a path.

For Union County the two measures on this page point the same way: Strong Wind is the county's highest-rated modeled hazard (Relatively Moderate), and Severe Storm 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.

Data-matched county comparisons

Union County's closest FEMA peer: Pima County, AZ

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