No widely cited national survey isolates \"fear of being killed by a wildfire\" from general natural-disaster or climate anxiety, so we mark the perceived side as editorial intuition. Anecdotally, the prior is shaped almost entirely by the last headline event the reader lived near or watched — Paradise, California in 2018; the Australian Black Summer of 2019-2020; Lahaina on Maui in 2023; the Los Angeles county fires of January 2025 — and reverts to roughly zero in the years between. Residents of the Western US Wildland-Urban Interface and of fire-prone parts of Mediterranean Europe and Australia carry a persistent prior; almost everyone else treats wildfire as televised rather than real, and almost nobody of any geography has an explicit prior for the much larger smoke-mortality burden downwind.\n", "rough_estimate": "33.1% of US adults report being afraid or very afraid of a devastating wildfire (Chapman Survey 2024)", "kind": "survey", "survey_source": { "title": "Chapman University Survey of American Fears, Wave 10 — Complete List of Fears 2024", "publisher": "Chapman University", "url": "https://www.chapman.edu/wilkinson/research-centers/babbie-center/_files/2024-csaf-fears-high-to-low.pdf", "year": 2024 } }, "native": { "display": "~1 in 100,000 global adult lifetime (direct wildfire death)", "numerator": 800, "denominator": 8000000000, "unit": "per year", "population": "global" }, "normalized": { "lifetime_us_adult": 0.00001, "display": "1 in ~100,000 lifetime (global adult, direct wildfire death)", "log_value": -5, "assumptions": "The headline is DIRECT wildfire deaths — people killed by the fire itself (burns, entrapment during evacuation, structure collapse, heat).

Australia's 2019-2020 Black Summer killed ~33 people directly plus several hundred more from smoke exposure. Globally, including Mediterranean Europe, Indonesia peat fires, and boreal Russia/Canada, a rough long-run direct-death anchor is a few hundred to ~1,000 per year. Using ~800/yr globally and a population of ~8 billion gives ~1e-7 per year; compounded over 60 adult years ≈ 6e-6, rounded upward to 1e-5 ≈ 1 in 100,000 to reflect the rising trend in WUI exposure in the US West and boreal forests since ~2000.

Johnston et al. 2012 estimated ~339,000 global deaths per year from landscape fire smoke, and subsequent work on the 2015 Indonesia peat fire haze (Koplitz et al.) and on recent Western US seasons suggests the number has grown since. Smoke mortality is roughly 100x the direct-fire mortality and is concentrated in populations — urban, downwind, cardiopulmonary-compromised — that do not typically see themselves as at wildfire risk at all.
