The verdict

Two federal records point in the busier direction for Polk County. Its 30 FEMA declarations are 43% above the Texas county mean and exceed the count for 86% of the 3,266 counties in this registry. Separately, FEMA's National Risk Index places it in the riskiest 24%, based on modeled expected annual loss, social vulnerability, and community resilience.

What does Polk County's hazard record show?

Reading the federal records together

The NFIP claims register shows a middle-volume loss record here: 346 paid claims, totaling $10.1M. PlainHazard uses 50-499 claims for this descriptive band; FEMA does not publish it as a safety or coverage category. The $29.1K average describes payments on recorded claims only, leaving uninsured damage and properties without a claim outside the measure.

The declaration register points in the busier direction. Polk County's 30 federal records stand 43% above the Texas county mean of 20.9. That comparison describes how often federal action was recorded, including any Major Disaster, Emergency, and Fire Management entries shown on this page; it does not convert the count into future probability.

FEMA National Risk Index

This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 75.6/100 (Relatively Low). Expected Annual Loss is rated Relatively Low (roughly $24.5M in annualized losses). Social vulnerability reads Very High and community resilience Very Low, both critical modifiers of realized harm here. Of the 18 hazards FEMA models, Lightning stands out as the sharpest exposure here, rated Relatively High. FEMA's modeled frequency puts that hazard at an average of 70 times per year here, based on 177,107 historical events on record.

Declaration frequency

The FEMA register is busy by both local and national comparisons. It contains 30 entries for Polk County, including 20 Major Disaster records, 43% above the Texas county mean. Across the 51-year span, that works out to 0.6 declarations a year. Hurricane leads the file with 9 entries. Declaration type records the federal action taken, not every assistance program approved.

How often does each hazard strike Polk 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.

Lightning Relatively High an average of 70 times per year
Hurricane Relatively Moderate roughly once every 9 years
Strong Wind Relatively High an average of 1.7 times per year
Tornado Relatively Moderate roughly once every 1 years
Cold Wave Relatively Moderate roughly once every 2 years
Heat Wave Relatively Low 12 modeled event-days per year
Ice Storm Relatively Moderate roughly once every 2 years

What Hurricane declarations mean here

Hurricane is the most frequent declaration type on Polk County's federal record, 30% of its declarations. Atlantic tropical systems run on a defined season, 1 June to 30 November, with most activity concentrated between August and October; Pacific and territorial basins run on their own calendars. A single named storm routinely produces one declaration number covering a long corridor of counties at once, well inland as well as on the coast, which is why an affected county's count can jump by several in one year without several separate events having occurred.

One practical distinction matters when reading these records: a tropical declaration usually bundles wind, storm surge and inland rainfall flooding under a single incident, but the insurance behind them is split. Wind damage falls to property insurers, while flood and surge damage is covered only under a separate National Flood Insurance Program policy. That is why a county can show heavy declaration activity and a comparatively small NFIP claims record, or the reverse.

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: Lightning

Lightning is modeled as a high-frequency, low-per-event hazard: strike counts are large, but each strike affects a very small area. Its aggregate cost accumulates through structure fires, electrical and electronic damage, and it is one of the few hazards whose risk is essentially continuous through the season rather than episodic.

Worth noting for Polk County: the model and the federal record do NOT point at the same hazard. Lightning carries the highest modeled rating (Relatively High), while the county's declaration history is led by Hurricane. 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.

Polk County's closest FEMA peer: Broome County, NY

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

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 Polk County

Polk County, TX has 30 federal declaration records, 43% more than the Texas county mean of 21; its history sits in PlainHazard's high activity band.

  • Within this above-state-average declaration file, major disaster leads with 20 of 30 records; the category describes past federal action, not the next likely hazard. Texas overview
  • The state benchmark and national rank point the same way: this count tops the Texas mean and the totals for 86% of 3,266 U.S. counties. Most-disaster rankings
