    "description": "Knife attacks occupy a disproportionate share of crime anxiety, partly because they are viscerally frightening and heavily covered in local news. No major US survey directly asks about worry over being stabbed, but proxy data suggests elevated concern: Gallup's 2025 poll finds 27% of US adults worry about being \"attacked while driving\" and 29% about being mugged, placing interpersonal violence fears in the 20-30% range. Knife-specific fear likely sits within that band, amplified by media salience.\n",

The 2023 aggravated assault rate is 264.1 per 100,000 (Statista/FBI), implying roughly 885,000 aggravated assaults nationally (264.1 × 3.35 million hundreds of population). Applying the historical 17.5% knife share yields ~155,000 knife-involved aggravated assaults per year, or roughly 46.3 per 100,000 population (~0.000463 annual probability). Compounding over 59 adult years: 1 − (1 − 0.000463)^59 ≈ 0.027. This is the probability of being a victim of at least one aggravated assault involving a knife/cutting instrument, not the probability of being physically stabbed — some incidents involve threat or display of a knife without contact injury. The true \"stabbed with wound\" probability is lower, perhaps half.\n",

  "caveats": "The FBI UCR category \"aggravated assault with knife or cutting instrument\" includes incidents where a knife was brandished or threatened but no stabbing occurred. The fraction of these incidents that result in an actual stab wound is not separately reported in national data, but emergency department studies suggest roughly half of knife-involved aggravated assaults produce a penetrating injury. The true \"stabbed with a wound\" lifetime probability is therefore likely in the range of 1 in 60 to 1 in 80 rather than 1 in 37. FBI data captures only incidents reported to law enforcement; the NCVS, which includes unreported assaults, would yield a higher figure. The 17.5% weapon share is from 2019 (last full legacy UCR year) applied to the 2023 aggregate — the NIBRS transition makes direct weapon-type percentages for 2023 harder to extract, though historical stability in the 17-18% range suggests limited error. Young urban men face dramatically higher risk than the population average.\n",
