The FEMA NRI release December 2025 lists Tornado at a 89.5 percentile for Sangamon County, the reference-point county or equivalent used here.

An event count or FEMA percentile cannot establish a policy exclusion, predict a loss or price your insurance.
Prepare your Comprehensive Coverage discussion in Springfield
Describe the actual garaging address and whether the vehicle is outdoors, under cover or in storage. Ask how the proposed contract treats flood, hail, theft and glass and which deductible applies. Confirm coverage from the contract rather than a community hazard ranking. Use your actual garaging address in Illinois and state the effective date you need; the community figures above do not replace those application facts.
Check the geography and the decision separately
The Census geography used is Springfield city, Illinois (place). Its estimate may not match a postal neighborhood or cover the same area as Sangamon County. Use the Illinois insurance regulator for current consumer rules and the motor-vehicle authority for licensing or filing instructions. A provider must confirm eligibility, policy terms and price; none is inferred from these community figures.
ACS five-year figures are survey estimates over a period, not live counts. Do not use small differences to rank cities, or treat an estimated zero as proof that no residents fit a category. County hazard and event records can span areas outside the city. No community measure is used here to set a personal premium. Sources and editorial methodology
How to use the local evidence
Households with one vehicle available — Springfield
21,764 of 51,040 in the relevant ACS survey universe (42.6%). Among 121 source-qualified place communities in Illinois with at least 20,000 residents, the median share is 34.8%. The Springfield estimate differs by 7.9 percentage points above that median. This is an unweighted comparison of community estimates, not the statewide population share or a statistically tested difference. Source: 2024 ACS five-year estimates for Springfield city, Illinois. One-vehicle households may have limited backup transport, but the estimate does not show how your household travels. Ask how a covered non-collision loss would affect rental transport, glass and deductible choices. Check the separately scoped county weather record rather than treating household counts as a hazard score.
