    "description": "Fireworks injuries occupy a predictable annual news cycle: every late June, local TV stations run segments on emergency-room horror stories featuring mangled hands and facial burns, accompanied by a solemn CPSC press release urging caution. The coverage creates a reasonable but somewhat inflated sense of risk. No standalone survey asks Americans to estimate their personal probability of a fireworks injury, so the perceived side is editorial intuition. Most adults who handle consumer fireworks probably underestimate the risk relative to their specific exposure (they have done it many times without incident), while bystanders and non-users probably overestimate the population-level rate because the injuries are vivid and seasonally concentrated. The net effect is a perception anchored on dramatic hand and eye injuries that are real but rare.\n",

    "assumptions": "The CPSC reported an estimated 14,700 fireworks-related emergency department visits in 2024 (up 52% from the 2023 estimate of 9,700). Against a US population of approximately 335 million, this yields an annual rate of roughly 44 per 1,000,000, or 4.4 per 100,000.\nHowever, the 2024 spike may be anomalous. The 5-year average (2019-2023) is closer to 10,000-11,000 ER visits per year, yielding an annual rate of approximately 32 per 1,000,000. Using the 5-year average as the more stable estimate:\nAnnual rate: ~32 per 1,000,000 = 0.000032 Compounded over 59 years of remaining adult life: 1 − (1 − 0.000032)^59 ≈ 0.00189\nUsing the 2024 rate for the central estimate to reflect the upward trend in consumer fireworks use: 1 − (1 − 0.000044)^59 ≈ 0.0026 ≈ 1 in 385.\nThe CPSC also reported 11 fireworks-related deaths in 2024 and 8 in 2023. The 5-year average is approximately 9 deaths per year, yielding a lifetime fatality probability of roughly 1 in 630,000 — negligible relative to the injury probability.\nThis is a population-average figure. Adults who never handle fireworks face near-zero risk (bystander injuries are a small minority). Adults who handle consumer fireworks on July 4th face a per-session risk roughly 10-20x the population average.\n",

The 2024 figure is a 52% increase over 2023 (9,700), likely reflecting both increased consumer fireworks availability (many states have liberalized fireworks laws since 2020) and increased usage. The body- part distribution (hands/fingers 36%, head/face/ears 22%) and the burn share (37%) are consistent with prior years. The 11 deaths are mostly associated with misuse (holding lit devices, re-lighting duds) and device malfunction. The adult age-group share (25-44 at 32%, 15-24 at 24%) confirms that this is not primarily a pediatric injury — adults are the majority of victims.\n"

The 2023 report notes that teens 15-19 had the highest per-capita rate, consistent with the behavioral risk profile (adolescents are more likely to mishandle fireworks).

Sparklers are often perceived as safe — they are the firework most commonly given to children — but burn at 1,200°F and produce a meaningful injury share. The 52% year-over-year increase is notable but should be interpreted cautiously: fireworks ER visits have fluctuated between 9,000 and 15,600 since 2019, and single-year spikes are common in this data series.\n"

  "caveats": "This entry covers all fireworks-related emergency department visits as reported by the CPSC through NEISS, including burns, lacerations, contusions, and eye injuries. The majority of injuries are minor burns that resolve without lasting impairment; serious outcomes (amputations, permanent vision loss, death) are a small fraction of the numerator. The 2024 figure of 14,700 may represent a temporary spike rather than a new baseline; the 5-year average is closer to 10,000-11,000. The annual rate is heavily concentrated around July 4th (roughly two-thirds of annual injuries occur in the June 18 - July 18 window), making this a seasonal rather than year-round risk. The population-average lifetime figure of ~1 in 385 includes adults who never touch fireworks; for active handlers the lifetime risk is materially higher. Professional fireworks displays have a separate and much lower injury rate for spectators; the CPSC numerator is dominated by consumer-fireworks injuries. State-level variation is significant: states with liberal fireworks laws (e.g., Missouri, Texas) have higher per-capita injury rates than states that ban consumer fireworks.\n",
