Perceived

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.

Rough estimate: ~1 in 5 adults express general worry about violent attack

Actual

~155,000 aggravated assaults with knife/cutting instrument per year

US population (~335 million; FBI UCR/NIBRS, 2023 weapon-type breakdown)

Show derivation

FBI UCR data for 2019 (last year with full legacy reporting) shows knives or cutting instruments accounted for 17.5% of aggravated assaults. 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.

Caveats: The FBI UCR category "aggravated assault with knife or cutting instrument" inclu…

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.

Compare to:

FBI data indicates that knives or cutting instruments are involved in roughly 17.5% of aggravated assaults, translating to an estimated 155,000 incidents per year across the United States. Compounded over a 59-year adult life, the population-average lifetime probability of being the victim of at least one knife-involved aggravated assault is approximately 1 in 37, or about 2.7% — roughly eight times the lifetime odds of being murdered but far less likely than a home burglary.

The number is higher than most people expect from a “rare violent crime,” yet lower than the anxiety it generates. Knife attacks are viscerally frightening and disproportionately covered in local news, which inflates their salience via the availability heuristic. The FBI category also includes incidents where a knife was displayed or threatened but never made contact, so the fraction resulting in an actual stab wound is meaningfully smaller — perhaps half, based on emergency department admission data. The real “stabbed and injured” figure is closer to 1 in 70.

Geography and demography drive the variance. Young men aged 18-24 in high-crime urban areas face roughly three to four times the population average risk. Women face about half. Rural residents face less than urban ones. The population-level number is accurate as an average and misleading as a personal forecast for anyone who knows their own neighborhood and demographic profile.

Knives or cutting instruments were used in 17.5% of aggravated assaults in 2019

Excerpt

“"In 2019, knives or cutting instruments were used in 17.5 percent of aggravated assaults. Firearms were used in 26.3 percent, other weapons in 27.5 percent, and personal weapons (hands, fists, feet, etc.) in 28.6 percent." ”

Calculation

FBI UCR 2019 is the last year of full legacy Summary Reporting System data with a clear weapon-type percentage table. The 17.5% knife share has been stable within 1-2 percentage points since 2010 (ranging 17.2%-18.0%). Applied to the 2023 estimated aggravated assault count of ~885,000 (derived from the 2023 rate of 264.1/100K × 335M population): 0.175 × 885,000 ≈ 155,000 knife-involved aggravated assaults per year. Annual risk per person: 155,000 / 335,000,000 ≈ 0.000463. Lifetime: 1 − (1 − 0.000463)^59 ≈ 0.027.

Aggravated assault decreased an estimated 2.8% in 2023; rate of 264.1 per 100,000

Excerpt

“"Aggravated assault figures decreased an estimated 2.8 percent. The FBI released detailed data on over 14 million criminal offenses for 2023 reported to the Uniform Crime Reporting (UCR) Program by participating law enforcement agencies. More than 16,000 agencies, covering 94.3% of inhabitants, submitted data through NIBRS." ”

Calculation

The 2023 aggravated assault rate of 264.1 per 100,000 comes from FBI NIBRS estimates. With a US population of approximately 335 million, this implies roughly 885,000 reported aggravated assaults. The 2.8% decrease from 2022 is consistent with a multi-year declining trend in violent crime. These are law-enforcement-reported incidents; the NCVS estimates substantially more aggravated assaults when unreported incidents are included.

Independence

FBI NIBRS collects data from law enforcement agencies. The weapon-type breakdown (17.5% knife) is from the 2019 UCR legacy system, applied to the 2023 aggregate count. The two data points are from the same FBI program but different reporting years and systems.
