How Irwin compares
Inside Missouri, Irwin sits at just the 35th percentile even though it scores 51st nationally — the state's overall wildfire exposure is high enough to make this a relatively quiet corner of it. Among the 31,521 US communities USFS scores, Irwin ranks 15,317 for wildfire risk (1 is highest) and 30,429 by building count (1 is largest). Within Missouri alone, it ranks 689 of 1,062 places by risk. See the full county-by-county picture for Missouri on its state page.
Irwin and the insurance market
At the 51st national percentile, Irwin rates elevated for wildfire risk — well short of the threshold where insurers have been withdrawing coverage, though comparing a quote costs nothing either way.
