Media coverage of major attacks and dramatic imagery from Ukraine drives availability-heuristic overestimates for those far from the war, while proximity and familiarity with specific incidents can cause underestimation in affected populations who normalize gradual attrition. No high-quality survey specifically asks populations to estimate the per-civilian probability of being killed or injured in a Ukraine-type conflict, so the perceived side is editorial intuition. Rough public estimates tend to cluster vaguely around \"very dangerous\" without distinguishing proximity to the front, city versus rural, or duration of exposure.\n", "rough_estimate": "~1 in 50 feels plausible to many Western observers; actual verified rate is closer to 1 in 500 over five years", "kind": "intuition" }, "native": { "display": "51,924 civilians (14,383 killed + 37,541 injured) confirmed by OHCHR through October 2025, against ~37 million residents remaining in Ukrainian-controlled territory", "numerator": 51924, "denominator": 37000000, "unit": "over 3.5-year conflict (Feb 2022 to Oct 2025)", "population": "Civilians residing in Ukrainian-controlled territory during the full-scale invasion, excluding the approximately 6-7 million who fled abroad" }, "normalized": { "lifetime_us_adult": 0.002004, "display": "~1 in 500 over a five-year conflict", "log_value": -2.698, "assumptions": "The UN Human Rights Monitoring Mission in Ukraine (HRMMU/OHCHR) confirmed 14,383 civilians killed and 37,541 injured from February 24, 2022 through October 2025, a period of approximately 3.5 years. The HRMMU explicitly acknowledges that \"the real number is higher\" due to verification lag and restricted access in Russian-occupied territories. Native numerator: 51,924 (killed + injured). Native denominator: approximately 37 million residents who remained in Ukrainian-controlled territory, derived by subtracting approximately 6-7 million refugees who left the country from a pre-war Kyiv-controlled population of roughly 44 million (UN/UNHCR refugee figures, noting ~4.5 million returns partially offset the outflow). The 3.5-year rate of 51,924 / 37,000,000 = 0.001403. Linearly extrapolated to 5 years: 51,924 × (5/3.5) / 37,000,000 = 74,177 / 37,000,000 = 0.002004. The linear extrapolation is conservative because 2025 showed a 31% increase in casualties over 2024 (HRMMU 2025 annual report), suggesting the rate has been accelerating rather than staying flat.
