  "quick_answer": "About 1 in 27 cumulative through age 14 for a US child riding in vehicles — roughly 147,000 of the nation's 59.5 million children are injured as vehicle occupants each year (a figure derived from NHTSA person-type counts), about 1 in 400 annually. Restraint status is the dominant lever: unrestrained children carry 3.2 times the per-crash injury odds of appropriately restrained ones.\n",

    "description": "Parental fear about cars is death-framed and event-framed — the drunk driver, the catastrophic highway crash — while the ordinary injury risk of ordinary rides barely registers as a category. The extensive attention parents give to car-seat brands and installation details coexists with little sense of the base rate those seats are working against; almost no parent could say whether a child's odds of ever being hurt in a crash are one in a thousand or one in twenty. The measured answer, about one in twenty-seven through age 14, sits closer to the second guess than most would expect, even though the large majority of those injuries are minor.\n",

Subtracting the two non-occupant person types leaves 147,284 — children injured while riding in vehicles, plus a small unattributed remainder of other non-occupants (skateboarders, scooter riders and similar), which is why the numerator is labeled derived. Against the same fact sheet's child population of 59,498,481 the annual rate is 147,284 / 59,498,481 ≈ 0.248% per year, about 1 in 400. Compounding over the 15 years from birth through age 14: 1 − (1 − 0.00248)^15 ≈ 0.0365, about 1 in 27. Using the full 161,478 all-person-type figure instead gives ≈ 0.040 (1 in 25), the upper end of the band; unreported injuries push higher still, while CRSS sampling error and repeat victims pull the distinct-child probability down.\n",

The child population denominator (59,498,481) is the fact sheet's own Table 7 US total, sourced to the Census Bureau.

Police-reported CRSS estimates miss unreported injuries and carry sampling error. Compounding a single-year rate over 15 childhood years assumes 2023 rates hold and years are independent; a child injured twice counts once against the distinct-child probability. Risk is not uniform across childhood or households — restraint use, who is driving, and impairment cluster: 25% of the 1,019 children killed in 2023 died in alcohol-impaired-driving crashes, and unrestrained drivers disproportionately carry unrestrained children.
