Illinois · FEMA + NOAA + National Risk Index
11 FEMA disaster declarations (1967-2020), with a FEMA National Risk Index rating of Relatively Low. Most common hazard: Snowstorm.
The verdict
Boone 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 14% below the Illinois county mean. FEMA's separate National Risk Index places the county in the riskiest 43%; that score models loss and vulnerability rather than counting declarations.
FEMA's National Risk Index and its declaration registry are separate measures. This county's registry includes Major Disaster (DR) and Emergency (EM) records; an EM authorizes a narrower set of federal assistance than a DR.

FEMA's modeled annual dollar loss for Boone County is led by Riverine Flooding (about $11.3M Expected Annual Loss, Historical Loss Ratio Relatively High), while Hail carries the highest National Risk Index rating (Relatively Moderate). EAL and risk score use different inputs; they need not agree.
Source: FEMA National Risk Index (December 2025 release) - Expected Annual Loss vs composite risk rating by hazard.
This county carries a high composite score on FEMA's National Risk Index, 57.3/100, rated Relatively Low. Its Expected Annual Loss rating is Relatively Low (roughly $21.4M in annualized losses), and a Relatively Low social-vulnerability profile combined with Relatively High community resilience shapes how much of that raw exposure becomes realized harm. Among the 18 modeled hazards, Hail carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at an average of 4.7 times per year here, based on 177 historical events on record.
Nationally, Boone County's 11 FEMA records form a high-volume history; within Illinois, however, the count is 14% below the county mean. 5 entries carry the Major Disaster classification. The largest incident group is Snowstorm, appearing 5 times. The full 53-year record averages 0.2 declarations annually. A DR label alone does not say whether Individual Assistance, Public Assistance, or both followed.
This county has a small entry in FEMA's NFIP paid-claims table: 46 claims and $271.3K 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 Illinois county averages 12.9 federal declaration records, while Boone County has 11. The gap is 14% 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'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 |
|---|---|---|
| Hail | Relatively Moderate | an average of 4.7 times per year |
| Tornado | Relatively Moderate | roughly once every 4 years |
| Cold Wave | Relatively Moderate | an average of 5.6 times per year |
| Lightning | Relatively Moderate | an average of 40 times per year |
| Riverine Flooding | Relatively Low | roughly once every 1 years |
| Strong Wind | Relatively Moderate | an average of 6.2 times per year |
| Drought | Relatively Low | 10 modeled event-days per year |
| Heat Wave | Relatively Low | 3 modeled event-days per year |
| Earthquake | Very Low | roughly once every 935 years |
| Winter Weather | Relatively Low | an average of 15 times per year |
| Ice Storm | Relatively Low | roughly once every 1 years |
| Landslide | Very Low | roughly once every 26 years |
| Hurricane | Very Low | roughly once every 170 years |
| Wildfire | Very Low | roughly once every 24,753 years |

Snowstorm is the most frequent declaration type on Boone County's record, 45% of its declarations. Snow-related declarations work on a narrower basis than most other hazards: they are generally issued to reimburse the cost of snow removal and emergency protective measures, rather than to repair destroyed property.
The qualifying test is unusual too. FEMA assesses snowfall against record levels for the affected area, so the same storm total can qualify in a county where it is historically extreme and not qualify a few hundred miles north where it is an ordinary winter. A low snowstorm declaration count is therefore not evidence of mild winters.
Declaration counts describe past federal action. They are a record of what was declared, not a forecast of future hazard probability.
FEMA categorizes declarations as Major Disasters (DR), Emergencies (EM), or Fire Management Assistance (FM).

Hail is among the most expensive hazards in the model relative to how little it threatens life. It concentrates on roofs, vehicles and crops, and a single severe storm can generate an insurance loss across a metropolitan area without a single injury.
Worth noting for Boone County: the model and the federal record do NOT point at the same hazard. Hail carries the highest modeled rating (Relatively Moderate), while the county's declaration history is led by Snowstorm. 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
Comparisons use published FEMA declaration fields plus the National Risk Index composite for Boone County. Record similarity, not a safety rating.
Boone County shows 11 FEMA declarations, led by Snowstorm.
Boone County: 5 of 11 of its declarations are Major.
Boone County: NRI composite 57.3 (Relatively Low).
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.
