School shootings have reached near-record levels in recent years — and the numbers look very different depending on which state you’re in, which data source you trust, and how you measure risk. This guide breaks down the state-by-state data, explains what the statistics mean for administrators and parents, and covers how schools are responding.
Key Takeaways
- The 2024–25 school year saw 254 total incidents, a 22.5% decrease from the prior school year — breaking a three-consecutive-year high. The decade-long trend, however, remains sharply upward.
- Raw incident counts mislead. Texas and California top the headlines, but Delaware and Washington, D.C. have the highest student exposure rates — the metric that actually reflects risk per student.
- Nearly 61% of school shootings occur at high schools. Location, time of day, and school type all affect risk — and most administrators don’t factor these into security planning.
- Most shooters are insiders. Since the majority of school shooters are current or former students, schools need more than just perimeter security.
- Federal grants exist to fund security upgrades — but schools that installed non-compliant cameras from banned manufacturers can lose eligibility entirely.
- NDAA compliance is non-negotiable for any school using federal safety grant money. Installing prohibited equipment can force a full system replacement at district expense.
What Are the School Shooting Statistics by State? Counts & Rankings
1. California led all states with 22 shooting incidents in 2025
California recorded more school shooting incidents than any other state in 2025 — a direct result of being the most populous state. Raw counts favor large states by default, which is why student exposure rate matters just as much for actual risk assessment.
2. Texas recorded 21 incidents in 2025, the second-highest total
Texas has ranked at or near the top of school shooting counts for multiple consecutive years. The state’s large school-age population and permissive gun access policies are both contributing factors cited by researchers.
3. Tennessee ranked third with 14 incidents in 2025
Tennessee is a notable example of a mid-size state with an outsized incident rate relative to population — a signal that raw counts and exposure rates can diverge significantly.
4. Georgia and Florida round out the top five
Georgia was home to the deadliest single K-12 school shooting of 2024 — the Apalachee High School attack in Winder, which killed two students and two teachers. Florida consistently ranks near the top due to its large school-age population.
5. New York ranks eighth despite being the fourth-most populous state
New York’s relatively lower ranking suggests that policy environment and urban security infrastructure can meaningfully suppress incident rates. Population alone does not determine risk.
6. Delaware has the highest student exposure rate — 359 per 100,000
Exposure rate measures how many students per 100,000 were affected by a school shooting. Despite far fewer absolute incidents than Texas or California, Delaware leads the nation because each incident affects a higher proportion of its smaller student population.
7. Washington, D.C., ranks second at 356 per 100,000
D.C.’s small size means any incident has an outsized statistical impact. Like Delaware, it consistently ranks near the top in exposure rate despite rarely appearing in national school violence headlines.
8. Utah, Arkansas, and Nevada all exceed the national exposure average
Utah (166 per 100,000), Arkansas (130), and Nevada (127) all carry exposure rates above the national average — yet receive far less attention than states with higher absolute counts. Administrators in these states who rely on headline rankings may underestimate actual risk.
9. Louisiana ranks 14th in incidents but second in per-capita rate
Louisiana is only the 25th-largest state, but it ranks 14th in total incidents and has the second-highest per-capita rate in the country. Gun access, poverty, and limited prevention infrastructure all drive this disparity.
10. Southern states have the highest regional rates relative to population
Relative to population, states in the South have experienced the highest rates of school shootings since 2008. Regional patterns in gun access, community violence, and policy investment all contribute.
11. Wyoming, Vermont, Maine, and others have near-zero recorded incidents
States including Wyoming, New Hampshire, Maine, North Dakota, South Dakota, Alaska, Montana, Vermont, and West Virginia have recorded near-zero incidents over the past two decades — driven by smaller populations, lower density, and stronger community prevention in some cases.
12. Rural school shootings are consistently underestimated
Even though roughly twice as many students attend urban schools compared to rural schools, the rate of shootings at rural schools is approximately 2x higher when adjusted per student. Geographic location is not a reliable predictor of safety.
What Are the Overall School Shooting Statistics?
13. 336 school shootings were recorded in 2024
The K-12 School Shooting Database counted 336 total incidents in 2024 — the second-highest annual total since records began in 1966. Only 2023, with 352 incidents, was worse.
14.The 2024–25 school year showed a meaningful decline to 254 incidents
There were 254 total school shooting incidents in the 2024–25 school year, compared to the nearly 330 incidents in each of the three prior school years. David Riedman, founder of the K-12 School Shooting Database, noted: “While this is progress, the total is still more than double the number of shootings pre-pandemic.”
15. 2021–2024 were all record-setting years
The four years following the pandemic represented the worst stretch of school gun violence since at least 2008. The 2020 dip — when school buildings were largely closed — underscores how closely incidents track in-person attendance.
16. Different databases produce wildly different counts for the same year
In 2024, the K-12 SSDB counted 336 incidents; Everytown for Gun Safety tracked at least 219; CNN counted 83; Education Week — which requires at least one bullet wound to a non-shooter — counted 39. The differences come down to criteria: whether accidental discharges count, whether no-injury incidents count, and whether college campuses are included. Administrators writing grant proposals need to understand which definition their funding source uses.
17. Casualties have increased 715% since 2004
Between 2004 and 2024, the number of people wounded and killed in school shootings increased by 715%. Deaths and injuries have risen even faster than incident counts, reflecting increasingly deadly individual events.
18. 2,980 total incidents have been recorded since 1966
Since tracking began, the U.S. has recorded 2,980 school shooting incidents — 2,385 victims wounded and 855 killed. An additional 256 shooters were also killed.
19. 80–90% of global school shootings in the United States and worldwide
American children are 21 to 23 times more likely to be killed with firearms than children in other high-income countries, a gap that cannot be explained by population size alone.
20. Guns are the leading cause of death for children and teens
Per CDC data through 2024, firearms remain the leading cause of death for Americans ages 1–19. School shootings are the highest-profile subset of a much broader crisis — and administrators who treat them as isolated, rare events are working from an incomplete picture.
21. Firearm incidents at schools rose 300% from 2016–2024
Even using conservative counting methods, incidents reported at K-12 schools tripled over this period. Multiple independent databases confirm this is a real increase — not a reporting artifact.
Which States Have the Highest Student Exposure Rate?
22. Exposure rate is the more useful metric for administrators
Raw counts favor high-population states by design — a state with 50 million residents will almost always record more incidents than one with 5 million, regardless of actual underlying risk. The right question isn’t “how many shootings happened in my state?” but “how many students were affected relative to the total student population?” That shift in framing produces a completely different set of high-risk states than what national headlines suggest.
23. Delaware leads at 359 per 100,000 students
With 359 incidents per 100,000 students over the 2020–2024 time period, Delaware’s students face the highest per-capita exposure rate in the country — despite rarely appearing in national school shooting coverage.
24. Washington, D.C. follows at 356 per 100,000
D.C.’s small geographic size means any shooting has an outsized statistical impact. It consistently ranks near the top in per-capita exposure despite low absolute incident counts.
25. Utah, Arkansas, and Nevada all exceed the national average
Utah (166), Arkansas (130), and Nevada (127) all have exposure rates that most administrators in those states don’t realize are above the national average. Headline rankings routinely obscure this.
26. Small-state administrators should not rely on absolute count comparisons
A district in a small state with two incidents in five years may face a higher per-student risk than a large urban district with 10 incidents in five years. Exposure rate — not raw count — is the appropriate benchmark for safety planning.
How Have School Shooting & Gun Violence Trends Changed Over Time?
27. Annual counts held relatively stable through the 2000s and early 2010s
Despite heightened awareness after Columbine, documented school shooting frequency remained relatively flat from the early 2000s through about 2013 before beginning a sustained upward trend. This plateau period led many districts to deprioritize security investment — a decision that proved costly as the sharp post-2018 acceleration unfolded.
28. A sharp acceleration began around 2018
From 2018 forward, annual incident counts rose markedly — correlating with worsening youth mental health outcomes, social media contagion effects, and increased community violence spilling into school settings. The compounding of these factors over a short period helps explain why the 2021–2024 records were broken so quickly and by such wide margins.
29. 2020 saw a near-complete stop when school buildings closed
There were just 10 school shootings with injuries or deaths in 2020, when schools were largely closed. This strongly suggests school attendance — not just gun access — is a primary driver of frequency.
30. 2021–2024 produced four consecutive record-setting years
Each year from 2021 through 2024 exceeded the prior record. This four-year streak is historically unprecedented.
31. 2023 set the all-time high at 352 incidents
The 2023 high of 349 incidents is the highest number in the K-12 SSDB’s dataset going back to 1966, cited repeatedly as evidence that security investment has not kept pace with rising violence.
32. 2025 showed more meaningful improvement
With approximately 230 incidents through year-end, 2025 represents a more substantial reduction. Whether it reflects a trend or a temporary plateau remains to be seen.
33. Casualties per incident are rising faster than incident counts
The 715% increase in casualties from 2004–2024 far outpaces growth in incident frequency. High-casualty events are becoming more deadly even as raw counts show modest recent improvement.
34. The contagion effect accelerates threats after major events
Following the September 2024 Apalachee High School shooting, school districts nationwide reported a surge in copycat threats. Security expert Ken Trump has documented this as a predictable post-incident phenomenon — and argues that reactive planning consistently fails where proactive planning would not.
Who Is Behind School Shootings? Shooter Demographics
35. Most shooters are current or former students
Research consistently shows that the majority of school shooters are enrolled students or recent alumni of the targeted school. This single fact undermines the premise that perimeter security is the primary defence — and it’s one of the most consequential statistics for administrators trying to design prevention systems that actually reduce risk.
36. Shooters are already familiar with the campus
Because most perpetrators have spent significant time in the school, they know entry points, camera locations, staff routines, and timing patterns. Physical hardening measures are less effective against someone who already knows the layout from the inside, which is why behavioral intervention must complement physical security rather than replace it.
37. Warning signs are almost always present beforehand
In the Secret Service’s analysis of 67 averted school attacks, in every single case a member of the community — a fellow student, school staff member, or parent — contributed to stopping the attack. The NTAC’s study of 41 targeted attacks found that 83% of attackers had warned of intent to threaten or kill before making an attempt.
38. Behavioral threat assessment is the highest-evidence prevention approach
School-based behavioral threat assessment — a structured, team-based process for identifying at-risk students and coordinating support — has stronger evidence behind it than any physical security measure. It is about early intervention and connection to mental health resources before behavior escalates, not profiling or treating students as suspects.
39. Most incidents are not premeditated mass casualty attacks
The image of a premeditated outsider attack targeting maximum casualties represents a fraction of actual incidents. Many are student disputes that escalated to gunfire on school grounds — requiring different prevention strategies than active shooter situation protocols.
When and Where Do School Shootings Happen?
40. Nearly 60% of K-12 incidents occur at high schools
High schools account for approximately 60% of all K-12 incidents. Elementary schools account for roughly 20%, middle schools around 10%. Security investment and staffing should reflect this concentration.
41. Dismissal time is a documented high-risk window
A substantial share of shootings occur at dismissal — in front of school buildings or in parking lots — when large numbers of students congregate with reduced supervision and less structured activity. This is one of the most predictable and addressable vulnerabilities in a school’s daily security posture.
42. Parking lots and perimeter areas are common incident locations
A significant portion of incidents occurred not inside buildings but in adjacent outdoor areas, underscoring the importance of perimeter surveillance as a meaningful component of a layered security strategy. Schools that focus camera and monitoring coverage exclusively on interior spaces leave a documented gap.
43. Lunch periods and between-class transitions carry elevated risk
Times when students move freely, and supervision is diffused, have historically correlated with higher incident rates. Camera coverage in hallways, courtyards, and common areas provides better situational awareness during these windows, and active monitoring during these specific periods is more effective than passive recording.
44. Many incidents begin as interpersonal disputes
A meaningful percentage of school shooting incidents start as student altercations that escalate when a weapon is present on school property. These require different intervention strategies than premeditated attack protocols — including conflict de-escalation training, anonymous tip systems, and early identification of ongoing student conflicts.
What Is the Real Cost of School Shootings?
45. Mental health impacts on survivors are severe and persistent
Students who witness or survive a shooting face elevated rates of PTSD, depression, and anxiety — effects documented to persist for 5–10 years or longer. Academic performance typically declines measurably, and some children never fully return to their pre-trauma trajectory.
46. The psychological radius extends beyond direct witnesses
An estimated 3 million children in the U.S. are exposed to gun violence per year. The devastating impact of a school shooting extends far beyond those who witnessed it directly — which is why community-wide trauma response has become standard practice.
47. The school security market is growing at over 11% annually
The global school and campus security market reached $3.0 billion in 2024 and is expected to grow to $9.2 billion by 2033, at a CAGR of 13.35%. 93% of public schools now use security cameras to monitor their campus, but quality, compliance, and effectiveness vary enormously across communities.
48. Non-compliant cameras can cost districts their federal grant eligibility
Schools that installed cameras from banned manufacturers — Hikvision or Dahua — before understanding NDAA requirements face a forced full-system replacement to remain eligible for federal safety grants. This can run into six figures for a medium-sized district.
49. Ongoing monitoring costs are almost always underbudgeted
Hardware installation is just the start. Security monitors average $41,245 annually. Remote video monitoring runs $250–$5,000 per month. Districts that budget only for installation often face shortfalls, leaving cameras running but unmonitored.
50. Grant matching requirements add a hidden cost
The SVPP federal grant requires a 25% local cash match. Many administrators discover this only after planning a budget based entirely on grant funding, creating unexpected district-level expenses.
How Do Mass Shootings Differ From Other Incidents on School Grounds?
51. The federal “mass shooting” definition is extremely narrow
The federal government’s most-used definition — three or more people killed, not counting the shooter — captures only a small fraction of all school shooting incidents. In 2024, only the Apalachee High School shooting met this threshold among K-12 incidents.
52. Broader definitions capture the full risk landscape
Everytown for Gun Safety’s approach (any firearm discharge on school property) and the K-12 SSDB’s approach (any gun fired or brandished on school grounds) capture the full range of gun violence affecting students — including disputes and accidental discharges that represent the majority of incidents and cumulative trauma.
53. Definition choice affects grant language and reporting
Administrators writing safety grant applications need to match the incident definition used by their funding source. Mixing frameworks from different databases can weaken a proposal or create compliance problems during reporting.
54. Mass shootings generate disproportionate policy attention
High-casualty events drive legislation and funding cycles but account for only a small share of total incidents. The far more common low-casualty incidents receive less attention while collectively accounting for most long-term student trauma exposure.
Which Groups Face the Greatest Risk of School Shootings?
55. High school students face the highest absolute risk
With nearly 60% of incidents occurring at high schools, students ages 14–18 face the highest exposure by school type. Security investment, threat-assessment staffing, and behavioral-intervention resources should be weighted accordingly — elementary school security matters, but data consistently point to high schools as the highest-frequency setting.
56. Students in Southern states face elevated regional risk
States in the South have consistently reported the highest rates of school shootings relative to their populations since 2008 — driven by gun access, socioeconomic factors, and variation in state-level prevention programs. This regional pattern holds even after controlling for population size.
57. Small-state students face underestimated per-capita risk
Students in Delaware, Washington, D.C., Utah, Arkansas, and Nevada face per-capita risks exceeding those in states that dominate the headlines. This is one of the most consistently underreported patterns in the data, and it means administrators in these states are routinely working from an inaccurate baseline.
58. Educators and staff are significantly affected as well
Teachers, administrators, and support staff face documented rates of occupational trauma, burnout, and PTSD following school shootings — and some have left the profession as a direct result. Staff mental health and training are part of a comprehensive school safety framework, not an afterthought to be addressed only after a crisis.
How Are States Responding to School Shootings: Policy & Prevention Strategies
59. Access control addresses outsider threats specifically
Single-point entry design, electronic access control systems, and controlled vestibules create time and space between a potential outsider threat and students. This is most effective against outsider threats—an important distinction, given that most shooters are insiders.
60. Security cameras work best when actively monitored
Cameras that are not monitored in real time primarily produce post-incident documentation, not prevention. Schools investing in video surveillance should also budget for active monitoring. Our guide to school security cameras covers how to build a monitoring strategy that actually works.
61. Cloud-based systems allow multi-campus oversight
Cloud-based video management platforms enable administrators or security officers to monitor all campuses from a single location — reducing per-campus staffing requirements while maintaining continuous coverage across the entire district.
62. Anonymous threat reporting systems have strong evidence behind them
The CDC and multiple academic studies identify anonymous, student-accessible threat reporting systems as among the highest-evidence interventions for preventing targeted violence. Students often know something is wrong before adults do — and they need a low-risk channel to report it without fear of social consequences or retaliation.
63. Behavioral threat assessment teams are the recommended standard
The structured, team-based approach — involving counselors, administrators, and, often, law enforcement officers — for identifying at-risk adolescents before behavior escalates is widely recommended by the Secret Service, the FBI, and academic researchers as the most effective prevention framework available. It is not about surveillance or profiling; it is about early connection to support.
64. State grant programs are funding significant security upgrades
Multiple states have created dedicated school safety grant programs. Texas allocated approximately $275 million through its SAFE grant program. Missouri dedicated $70 million over two rounds. Utah allocated $100 million in one-time safety funding. Indiana’s SSSG program offers up to $100,000 per application.
65. Federal grants fund cameras, access control, and more
The School Violence Prevention Program (SVPP) allocates approximately $70–73 million annually to K-12 schools. Individual awards reach up to $500,000 with a 36-month performance period. FEMA’s Nonprofit Security Grant Program offers up to $274.5 million in FY2025 for eligible institutions.
66. NDAA compliance is mandatory for federally funded security equipment
Any school using federal grant funds to purchase security cameras must use NDAA Section 889-compliant products. Equipment from Hikvision, Dahua, Huawei, Hytera, or ZTE is prohibited. Schools that installed these brands face full replacement costs to restore grant eligibility. See our NDAA compliance guide for the full breakdown.
67. CMAS, PEPPM, and cooperative purchasing programs simplify procurement
Schools don’t need to run full competitive bids for every security purchase. Cooperative purchasing programs — including CMAS, PEPPM, and OMNIA Partners — offer pre-vetted vendors and pre-negotiated pricing. We’ve been approved for 15+ government procurement vehicles for exactly this reason.
68. Working with an NDAA-compliant integrator protects grant eligibility
A single non-compliant camera can jeopardize an entire grant award. We’ve helped K-12 districts across the country plan and install compliant systems that qualify for federal and state funding — contact us to discuss your district’s options.
FAQs
What States Have the Most School Fights?
School fights, physical altercations short of gun violence, share overlapping risk factors and campus locations with shooting incidents. As of 2022, U.S. public schools recorded 857,500 violent incidents, with 67% of schools reporting at least one violent incident. States with higher rates of community violence, including many Southern states and densely populated urban areas — tend to see higher rates of school-based altercations as well.
Are Schools Safer Now Than in the Past?
It depends on what you measure. Victimization rates for non-fatal offenses have declined significantly over the past 30 years. But school shooting incidents have increased dramatically since the mid-2000s, with the 2020s setting consecutive records. Many types of school crime have declined, but gun-specific violence has risen sharply. Whether schools are “safer” depends entirely on which risks you’re measuring.
What Is the Long-Term Impact of School Shootings on Survivors?
Students who witness or survive a shooting face significantly elevated rates of PTSD, with symptoms documented to persist for years. Academic performance typically declines, and many survivors experience long-term changes in social trust and mental health. An estimated 3 million children are exposed to gun violence per year, effects that extend to students who weren’t physically present.
Conclusion
School shootings are not randomly distributed. They concentrate in certain states, certain school types, and certain times of day, and understanding that distribution is the foundation of effective planning.
The data is clear: near-record incident rates, rising deaths and injuries, and an insider-threat profile that makes perimeter security alone insufficient. Behavioral threat assessment, layered physical security, NDAA-compliant surveillance, and available grant funding all give administrators real tools to work with.
The next step is to assess your district’s specific risk profile—and ensure your security investments are both effective and compliant. Explore our resources on school security cameras, NDAA compliance, and the benefits of security cameras for schools, or reach out to discuss your district’s options.
