Sumner, IL
Sumner, IL's wildfire risk, in USFS's own numbers
Out of every US place USFS scores, Sumner lands at the 4th percentile for wildfire risk to structures — among the lower wildfire-risk places nationally — a figure built from its 627 buildings, not the land around them. (Source: USFS's Wildfire Risk to Communities methodology.)
USFS's separate burn-probability score — fire likelihood alone, before counting what's built there — puts Sumner at the 4th percentile, close to its 4th-percentile risk score.
Where Sumner's buildings actually sit
Sumner rates 83.1% Minimal exposure against just 16.9% Direct and 0% Indirect — of 627 buildings counted, few sit close enough to burnable vegetation for USFS to flag them individually.
Sumner against the rest of the country
Compare Sumner's two percentiles: 23rd within Illinois, only 4th nationally — a gap of 20 points that marks it as unusually exposed for its own state. Among the 31,521 US communities USFS scores, Sumner ranks 30,312 for wildfire risk (1 is highest) and 15,478 by building count (1 is largest). Within Illinois alone, it ranks 1,110 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.
Shopping for coverage in Sumner
At the 4th national percentile, Sumner rates low for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
Hardening a home in Sumner
Sumner's 83.1% Minimal-exposure share means structure-level hardening matters less here than it would elsewhere — still worth the low-cost basics, per the home-hardening guide.
