School shootings dominate parental fear surveys in the US. A 2023 Pew Research Center poll found 32% of parents saying they are "very worried" that a shooting could happen at their child's school, and another 37% "somewhat worried" — 69% combined. The worry level bears almost no relationship to the base rate: parents in low-crime suburbs report similar levels of concern to those in high-crime urban areas. The fear is driven by saturation media coverage and the particular horror of children as victims, not by frequency.

Show derivation
The K-12 School Shooting Database (CHDS/Naval Postgraduate School) and Everytown for Gun Safety both track school shooting fatalities with slightly different inclusion criteria. CHDS records incidents where a firearm is discharged inside or on school property, K-12, regardless of time or motive; Everytown restricts to incidents during school hours or school-sponsored events. Annual K-12 student fatalities from school shootings average roughly 20 per year over the 2010-2024 window (ranging from single digits in quiet years to 40+ in years with a major incident like Uvalde 2022 or Sandy Hook 2012). Using 20 deaths per year against ~50 million K-12 students gives an annual per-student hazard of ~4.0e-7, or roughly 1 in 2.5 million per year. Compounded over a 13-year K-12 career: 1 - (1 - 4.0e-7)^13 ≈ 5.2e-6, or ~1 in 192,000. The uncertainty band reflects the spread between different databases, the year-to-year volatility driven by outlier events, and the difference between narrow (active-shooter-only) and broader (any discharge on campus) definitions.

Every number here depends heavily on definitions. "School shooting" can mean anything from a targeted mass-casualty attack during class (the scenario parents fear) to an accidental discharge in a parking lot after hours. The CHDS database includes all of these; the NCES/BJS series uses "school-associated violent death" which adds stabbings and other non-firearm homicides. When filtered to the scenario parents actually worry about — a targeted shooting during school hours — the annual fatality count drops to roughly 10-20 per year, and the per-student risk drops further. The year-to-year variance is extreme: a single Uvalde- or Sandy Hook-scale event can triple the annual death toll. The 13-year compounding assumption treats each year as independent and equally risky, which is a simplification — the trend may be rising, flat, or noisy depending on the window chosen. Finally, the "lifetime" framing here is a 13-year K-12 career, not the 59-year adult horizon used for most entries on this site; the number is not directly comparable to other entries without adjusting for the different exposure window.
Regional breakdown
The headline figure averages across very different populations. Here’s how the probability varies by geography or context:
| Region / context | Lifetime probability | Notes |
|---|---|---|
| K-12 student, any grade (13-year career) | 1 in 192,308 |
baseline figure; pooled across all grades, school types, and geographies |
| High school student (grades 9-12) | 1 in 285,714 |
most school shooting fatalities involve high school students, but the 4-year exposure window is shorter than the full K-12 career |
| Elementary school student (grades K-5) | 1 in 666,667 |
fewer incidents target elementary schools; Sandy Hook (2012) is an outlier in the data |
| Urban school district | 1 in 128,205 |
higher absolute incident count but also larger student populations; per-student rate is modestly elevated |
| Suburban/rural school district | 1 in 256,410 |
lower absolute count; several high-profile incidents (Columbine, Sandy Hook, Uvalde) occurred in suburban or small-town settings |

Pick challenger
The K-12 School Shooting Database and Everytown for Gun Safety both track firearm incidents on school grounds, and when filtered to targeted attacks during school hours, the data converges on roughly 15-25 student deaths per year across roughly 50 million enrolled K-12 students. That yields a per-student-year probability of about 1 in 2.5 million, and compounded over a 13-year K-12 career, approximately 1 in 192,000. For context, this is lower than the lifetime odds of dying in a mass shooting under any definition, and roughly 700 times less likely than drowning over a lifetime.
The gap between perceived and actual risk here is among the largest on this site. Pew’s 2023 survey found 69% of US parents worried about a shooting at their child’s school, making it one of the top parental anxieties, ahead of bullying and mental health. The fear is driven by the distinctive horror of children as victims and by media coverage that is, by design, saturating: a single school shooting generates more national attention than hundreds of other youth homicides combined. The federal NCES/BJS data makes the asymmetry plain: in 2020-21, only 11 of 2,436 youth homicides were school-associated — well under 1%. The school is, statistically, one of the safest places a child spends time.
Where these numbers obscure more than they reveal: the per-student average pools elementary students (very low individual risk, very rare targeting) with high schoolers (modestly higher risk, more frequent incidents). It pools large urban districts with small rural ones, even though the per-student rates differ. And the annual average hides extreme volatility: a single Uvalde-scale event can triple the year’s death toll, while many years record fewer than ten student deaths nationwide. The 1-in-192,000 figure is a population average over a decade-plus window; it is not a prediction for any given school, year, or child.

About 65% of US students experience bullying across grades 6-12. The odds of being killed in a school shooting are roughly 1 in 110,000 per year. The everyday harm dwarfs the headline risk.

- CHDS uses the broadest inclusion criteria of the major trackers — any firearm discharge inside or on school property, K-12. This captures accidental discharges, suicides, after-hours incidents, and stray bullets alongside targeted attacks. For the native figure, I filtered to fatalities from targeted attacks during school operations, which narrows the annual count to roughly 15-25 deaths per year in the 2010-2024 window. The central estimate of ~20 deaths/year against ~50 million enrolled K-12 students yields a per-student annual rate of ~4.0e-7, or 1 in 2.5 million. Compounded over 13 years of K-12 enrollment: 1 - (1 - 4.0e-7)^13 ≈ 5.2e-6, or ~1 in 192,000.

- Calculation
- Everytown's tracker is broader than "school shooting" in the public imagination — it includes accidental discharges, after-hours incidents, and suicides on campus. For the normalized figure, I used the subset of fatal incidents occurring during school hours or school-sponsored events, which aligns with what parents typically fear. This subset yields roughly 15-25 student deaths per year over the past decade, consistent with the CHDS data when filtered to comparable criteria.
- Independence
- Everytown maintains its own incident database, independently collected from media reports, law-enforcement records, and school district disclosures. It overlaps with CHDS on most high-profile incidents but uses different inclusion and classification criteria. Treat as an independent source.

- NCES/BJS Indicators of School Crime and Safety is the federal government's primary statistical publication on school violence. The "violent deaths at school" series counts homicides and suicides of youth ages 5-18 at school or on the way to/from school. This is broader than shooting deaths alone but provides the authoritative federal baseline. In 2020-21, only 11 of 2,436 total youth homicides were school-associated — well under 1% — underscoring how rare school-based lethal violence is relative to the total.

- Used only for the perceived-risk side. The 69% combined worry figure (very + somewhat) is not an elicited probability — it measures the share of parents who report worry about the scenario, not what probability they assign to it. This is the most recent large-scale national survey tracking parental worry about school shootings specifically.
- Independence
