    "description": "House fires occupy a peculiar spot in the American risk imagination. Almost every reader has stood next to a smoke alarm, read a hotel evacuation card, or rehearsed a family escape plan, and most understand intuitively that a working smoke alarm matters a lot. What almost nobody can name is the actual number: the annual US home fire death toll, the per-capita rate, or the lifetime odds. The direction of belief is roughly right — fire is real, smoke alarms help — but the magnitude is essentially unknown to the general public, which is why this entry is tagged as calibrated rather than debunked or underrated.\n",

USFA's 2023 per-capita series gives 13.1 deaths per million for all structure fires combined; the home-only subset is smaller. Taking 7.8 per million per year as the home-fire input and compounding across 59 years of remaining adult life gives 1 - (1 - 7.8e-6)^59 ≈ 4.6e-4, or about 1 in 2,170. Rounded up to 5.5e-4 (≈ 1 in 1,820) to account for the fact that adults 65+ experience fire death rates roughly 2-3× the all-ages baseline and most cohorts will pass through that band.
