    "description": "Ferry disasters surface in the global news cycle in brutal bursts — MV Doña Paz in 1987 (~4,000 dead, the deadliest peacetime maritime disaster on record), the Estonia in 1994, the Sewol in 2014, and a steady drip of capsizes in the Democratic Republic of Congo, Nigeria, Bangladesh, and the Philippines. We have not found a rigorous recent survey that isolates \"fear of dying in a ferry accident\" as a standalone item, so the perceived side here is editorial intuition rather than polled data. Most Western readers with no exposure to developing-world waterways probably hold a rough prior shaped almost entirely by televised footage of those single events.\n",

Annual per-capita risk ≈ 1,000 / 8,000,000,000 ≈ 1.25e-7; compounded over 60 adult life-years ≈ 7.5e-6, rounded to an order-of-magnitude 1 in 130,000. The uncertainty band reflects (a) under-reporting of developing-world incidents, which the WFSA and IMO both flag explicitly, and (b) window sensitivity — a single catastrophic year (Doña Paz 1987, Sewol 2014) can move the long-run average by a factor of several. This is an \"average global adult\" scale marker and is not a useful personal estimate for anyone — see the regional breakdown.\n",

The under-reporting is the direct reason we use the WFSA number as the primary anchor rather than the IMO number, and the reason the uncertainty band is asymmetric upward.\n",

Ferry risk is extraordinarily bimodal: developed-country scheduled services (EU, UK, Norway, Japan, US Washington State, Canada, Greece, Australia) produce roughly 20 fatalities per year across billions of passenger-journeys, while overloaded inland and coastal ferries in a handful of low-income countries produce nearly all of the remaining ~1,000-1,300 annual deaths. Averaging the two regimes produces a number that applies to neither. Under-reporting of incidents in the high-fatality regions is explicit in both the WFSA and IMO data; the true global figure is almost certainly higher than 1,000/year. A single catastrophic event (Doña Paz 1987, Sewol 2014) can double or triple the headline for any given year.\n",
