No formal survey asks parents to estimate the probability that their child will die before adulthood, but the fear scarcely needs quantification. It anchors an entire industry of safety products, drives helicopter parenting norms, and dominates pediatrician waiting-room anxieties. The availability heuristic does most of the work: every child death reported on the news feels like evidence that the baseline rate is high, precisely because such deaths are rare enough to be individually newsworthy. Most parents, if pressed, would guess a number far above the actual figure — some studies on domain-specific child risks (drowning, abduction, anaphylaxis) find parental estimates 10x to 100x the true rate.
Rough estimate: Parents intuit the risk is far higher than it is; few could name a number below 5%

Actual
~9.7 deaths per 1,000 live births before age 18 (US, 2022)
US children born alive
Show derivation
Derived from the CDC / NCHS 2022 United States Life Tables (NVSR Vol. 74, No. 2), Table 1 (total population). Out of a hypothetical cohort of 100,000 live births (both sexes combined), 99,029 survive to exact age 18 (the lx entry for the 18-19 age interval), implying 100,000 − 99,029 = 971 deaths per 100,000, or ~9.7 per 1,000. The World Bank / UNICEF indicator of ~7 per 1,000 covers only under-5 mortality, a subset of the birth-to-18 window; the life table's own lx at age 5 (99,328) puts under-5 mortality at ~6.7 per 1,000, so the full birth-to-18 figure necessarily exceeds it. The figure is a period life-table estimate, not a cohort projection — it assumes 2022 age-specific mortality rates persist unchanged. Roughly 58% of the cumulative risk is concentrated in the first year of life (560 of 971 deaths per 100,000; infant mortality rate 5.61 per 1,000 in 2023). The uncertainty band reflects year-to-year variation, racial/ethnic disparities (Black infant IMR ~10.9 vs Asian ~3.4 per 1,000), and state-level range (New Hampshire 2.9 vs Mississippi 8.9 per 1,000 for infants alone).
Caveats: The headline ~9.7-per-1,000 figure is a period estimate from the 2022 US life ta…
The headline ~9.7-per-1,000 figure is a period estimate from the 2022 US life table (Table 1, lx = 99,029 at exact age 18), not a cohort projection for children born in 2022. Note this exceeds the commonly cited World Bank under-5 rate of ~7 per 1,000 because under-5 is only a subset of the birth-to-18 window. If age-specific mortality continues its long-term decline, children born today will likely face even lower cumulative risk. Conversely, the 2021-2022 data showed the first year-over-year increase in infant mortality in two decades — partly attributable to the Dobbs v. Jackson decision's effects on access to reproductive care in some analyses, though causality remains debated. The regional_breakdown by age group uses approximate cumulative rates (annual rate × years) rather than exact life-table multiplication, so they sum to slightly more than the life-table total. The teen bracket uses an estimated 60 per 100,000/year for ages 15-17, extracted from the lower portion of the CDC's 15-24 age band. Racial and socioeconomic disparities are substantial and persistent: Black infant mortality remains roughly double the national average, and state-level variation spans a 3x range.
How the risk varies
The headline figure averages across very different situations. Here’s how the probability varies by scenario or context:
1 in 179
~58% of all under-18 mortality (560 of 971 deaths per 100,000); 5.61 per 1,000 live births (2023)
1 in 893
28.0 per 100,000/year × 4 years; leading cause: unintentional injury (drowning, motor vehicles)
1 in 654
15.3 per 100,000/year × 10 years; leading causes: accidents, cancer, congenital anomalies
1 in 556
~60 per 100,000/year × 3 years; leading causes: firearms, motor vehicles, suicide
1 in 103
1 in 14 · 6.9%
69 per 1,000 live births; ~7x the entire US birth-to-18 figure
1 in 5.0 · 20%
~200 per 1,000; roughly 1 in 5 children did not reach age 5

Roughly 10 out of every 1,000 children born alive in the United States today will not survive to their eighteenth birthday. That is the figure that falls out of the CDC’s 2022 period life tables — 99,029 survivors at exact age 18 from a hypothetical cohort of 100,000, meaning 971 deaths, or about 1 in 103. The number is dominated by infancy: the infant mortality rate of 5.6 per 1,000 accounts for roughly 58 percent of the total. After the first birthday, annual mortality drops to 28 per 100,000 for ages 1-4, drifts lower still through the school years at 15 per 100,000, then climbs again in the mid-teens as firearms, motor vehicles, and suicide enter the picture. The cumulative probability is, by any historical or global standard, astonishingly small.
The historical context is where the number becomes genuinely remarkable. In 1900, the CDC estimates that up to 30 percent of infants in some US cities died before their first birthday, and roughly one in five children did not survive to their fifth birthday — an under-5 mortality rate near 200 per 1,000. The current US under-5 rate is about 6.5 per 1,000, a reduction exceeding 95 percent in a little over a century, driven by sanitation, vaccination, antibiotics, obstetric care, and car-seat laws, among other unglamorous interventions. Globally, the picture is less uniform: sub-Saharan Africa’s under-5 mortality of 69 per 1,000 in 2023 exceeds the entire US birth-to-18 figure by a factor of about seven. A child born in the United States today faces lower mortality risk in the first eighteen years of life than a child born almost anywhere else at almost any other point in recorded history.
None of which makes the fear irrational. A ~1 percent probability is not zero, and the asymmetry of the outcome — one’s child dying versus not dying — is not a domain where expected-value arithmetic offers much comfort. What the numbers do clarify is the gap between perception and reality. Parents who restrict outdoor play, refuse to let children walk to school, or lie awake imagining abductions are responding to an availability signal, not a statistical one. The coverage of child deaths has intensified as the deaths themselves have become rarer, creating a paradox in which the safest generation of American children is raised by the most anxious generation of American parents. The 990 out of 1,000 who will reach adulthood are the untold story.

1 in 31 children (3.2%) will be diagnosed with autism. 0.7% of children die before age 18. Parents catastrophize the diagnosis that is 4x more common than the outcome they never think about.
The probability of a US child dying before age 18 from any cause is about 0.7%. Stranger abduction is orders of magnitude rarer. Parents reliably rate the rarer event as the greater threat.
A child has about a 7% chance of losing a parent before turning 18. The probability of a child dying before 18 is ~0.7%. Parents are 10x more likely to die during their child's youth than the reverse.

- CDC 2022 life tables, Table 1 (total population): lx at age 0 = 100,000; lx at the 18-19 interval (exact age 18) = 99,029 (both sexes combined). Deaths before 18 = 100,000 − 99,029 = 971. Probability = 971 / 100,000 = 0.0097, or ~9.7 per 1,000 (about 1 in 103). Cross-check within the same table: lx at age 1 = 99,440 (infant mortality 560 per 100,000 = 5.6 per 1,000) and lx at age 5 = 99,328 (under-5 mortality 672 per 100,000 = 6.7 per 1,000). Infancy accounts for ~58% of the cumulative birth-to-18 deaths (560 of 971).

- US under-5 mortality of ~6.5-7 per 1,000 is a subset — not the whole — of the cumulative birth-to-18 mortality (~9.7 per 1,000 from the life table). Under-5 alone is the floor; the additional ~3 per 1,000 accumulates from ages 5-17, driven by the low but nonzero school-age rate and the marked uptick in the teenage years (accidents, firearms, suicide). Because under-5 is a subset, the under-5 indicator and the birth-to-18 headline cannot be equal. Global average of 36.7 per 1,000 under-5 provides cross-country context.

- Age-band rates used to cross-check the life-table cumulative. Infant rate ~560 per 100,000 (5.6 per 1,000) dominates. Ages 1-4: 28.0 per 100,000/year × 4 years ≈ 112 per 100,000 cumulative. Ages 5-14: 15.3 × 10 ≈ 153. Ages 15-17 (estimated as lower end of 15-24 bracket): ~60 per 100,000/year × 3 ≈ 180. Sum: 560 + 112 + 153 + 180 ≈ 1,005 per 100,000, or ~1.0% — closely matching the life-table figure of 971 per 100,000 (~0.97%). This independent age-band cross-check corroborates the ~9.7 per 1,000 birth-to-18 headline derived from the life table's lx at age 18.

- The 1900 infant mortality rate of ~100 per 1,000 live births (with up to 30% infant mortality in some cities) anchors the historical comparison. With life expectancy near 47 years and high child mortality from infectious disease, roughly 20% of children born alive did not survive to age 5. Current US figure of ~6.5 per 1,000 under-5 represents a >95% reduction over 120 years.
