Pierron, IL
Pierron wildfire risk explained
USFS scores Pierron at the 8th national percentile for wildfire risk to structures (among the lower wildfire-risk places nationally), a figure built from 417 real buildings rather than raw vegetation cover. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Pierron at the 8th national percentile — 0 points above its risk-to-structures score, a gap driven by how much is actually built there.
Pierron's building exposure, zone by zone
Most of Pierron's buildings (85.9% of 417) fall outside USFS's Direct and Indirect zones entirely — that doesn't zero out the score above, it means the risk is regional, not structure-by-structure.
How Pierron compares
Pierron's 37th-percentile standing inside Illinois outpaces its 8th national percentile — this is a hotter spot than most of its own state, even though the state as a whole runs cooler nationally. Among the 31,521 US communities USFS scores, Pierron ranks 29,021 for wildfire risk (1 is highest) and 18,876 by building count (1 is largest). Within Illinois alone, it ranks 906 of 1,445 places by risk. See the full county-by-county picture for Illinois on its state page.
Pierron and the insurance market
Pierron's low rating (8th percentile nationally) sits outside the range where wildfire risk alone reshapes an insurance market — still, a homeowner here loses nothing by comparing rates.
What would actually reduce this score
With 85.9% of buildings rated Minimal exposure, Pierron gets less benefit from structure hardening than a Direct- or Indirect-dominant place would — the home-hardening guide explains why the zone matters.
