Thornburg, IA
Thornburg wildfire risk explained
USFS's Wildfire Risk to Communities model puts Thornburg at the 48th national percentile for risk to structures, modestly above the national average for wildfire risk — a score built from 69 actual buildings. (Source: USFS's Wildfire Risk to Communities methodology.)
Fire likelihood alone (USFS's burn-probability figure) ranks Thornburg at the 48th national percentile — 0 points below its risk-to-structures score, a gap driven by how much is actually built there.
What "at risk" means for the buildings here
Only 10.1% of Thornburg's 69 buildings carry Direct exposure and 0% carry Indirect; the remaining 89.9% are Minimal, which shifts the risk driving this page's score toward the surrounding landscape rather than any one structure.
Thornburg against the rest of the country

Thornburg and the insurance market
At the 48th national percentile, Thornburg rates elevated for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
Lowering exposure, not just insuring around it
Thornburg's 89.9% 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.
