FEMA National Risk Index composite score vs. the Illinois county average
What does Marion County's hazard record show?
FEMA National Risk Index
This county sits among the highest-risk counties nationally on FEMA's National Risk Index, a composite score of 77.1/100 (Relatively Low). Expected Annual Loss is rated Relatively Low (roughly $30.9M in annualized losses). Social vulnerability reads Relatively High and community resilience Very High, both critical modifiers of realized harm here. Among the 18 modeled hazards, Earthquake carries the county's highest rating, a mid-range Relatively Moderate. FEMA's modeled frequency puts that hazard at roughly once every 158 years here.
Declaration frequency
The state comparison is the clearest context for Marion County's moderate federal record. Its 8 declarations sit 38% below the Illinois county mean, with 6 Major Disaster entries among them. 3 records concern Severe Storm, the file's most frequent incident type. Spread across 30 years, the registry rate is 0.3 per year. FEMA reports authorized programs separately from the DR, EM, and FM codes.
Reading the federal records together
This county has a small entry in FEMA's NFIP paid-claims table: 29 claims and $548.3K 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 Marion County has 8. The gap is 38% 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 Marion 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 |
|---|---|---|
| Earthquake | Relatively Moderate | roughly once every 158 years |
| Strong Wind | Relatively High | an average of 4.6 times per year |
| Heat Wave | Relatively Moderate | 11 modeled event-days per year |
| Cold Wave | Relatively Moderate | an average of 1.5 times per year |
| Tornado | Relatively Moderate | roughly once every 2 years |
| Winter Weather | Relatively Moderate | an average of 7.8 times per year |
| Riverine Flooding | Relatively Low | an average of 1.1 times per year |
| Landslide | Relatively Low | roughly once every 3 years |
| Drought | Relatively Moderate | 1.7 modeled event-days per year |
| Hail | Relatively Low | an average of 3.4 times per year |
| Lightning | Relatively Low | an average of 50 times per year |
| Hurricane | Very Low | roughly once every 47 years |
| Ice Storm | Relatively Low | roughly once every 2 years |
| Wildfire | Very Low | roughly once every 37,179 years |

What Severe Storm declarations mean here
Severe Storm is the most frequent declaration type on Marion County's record, 38% 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: Earthquake
Earthquake is the model's clearest example of a hazard with no season and no warning. Its expected loss is driven less by how often shaking occurs than by how much of the building stock predates modern seismic codes, so exposure can be high in places where nothing has happened for a long time.
Worth noting for Marion County: the model and the federal record do NOT point at the same hazard. Earthquake 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 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 Marion County
Against a Illinois county mean of 13 declarations, Marion County, IL records 8, or 38% fewer. PlainHazard classifies that historical total as moderate activity.
- Major Disaster is the largest group (6 of 8) in a declaration history that remains below its state benchmark; frequency here is not a forecast. Illinois overview
- Nationally the county exceeds 6% of recorded county totals, but its own Illinois benchmark is higher. The ranking keeps those two contexts separate. Most-disaster rankings
- A short NFIP claims file cannot establish low flood exposure; the data guide explains the limits of each federal measure. Disaster-data guide
A below-average federal record is not a safety guarantee. Use National Weather Service alerts and local emergency-management notices for present conditions, not this historical comparison.
