Gun Violence in the US and in the World

This posting is inspired by the shootings at Brown University as wells as in Bondi Beach, Sydney, Australia yesterday..  

Gun violence in and around schools has become a defining moral crisis of this era, and the fact that the United States has recorded roughly 70 or more incidents on school grounds so far this year, depending on how incidents are defined, is both numbing and intolerable. Set against Australia’s much rarer history of school shootings after sweeping gun reforms in the 1990s, the contrast exposes how political will and public consensus can either entrench or interrupt a culture of armed fear.

The numbers behind the dread

Different trackers count school shootings in different ways, but they all tell the same story of relentless repetition in the United States. Broad databases that include any gunfire on school property register well over 100 incidents in 2025, while more restrictive counts that only include shootings with injuries or deaths still record dozens of tragedies that shattered classrooms and families. Advocacy groups estimate that this year alone, gunfire on school grounds in the U.S. has killed around a few dozen people and injured many more, with shots being fired at schools on average nearly twice a week.

Australia offers a stark counterpoint: over the last three decades, the entire country has recorded only a handful of school shooting incidents, most of them with no fatalities. Australia’s last recorded school shooting with no injuries occurred in 2012, and episodes of gun scares there today are treated as exceptional crises rather than grimly familiar news cycles.

What children are learning from this

Every bullet on school grounds teaches a hidden curriculum about what a nation values. In U.S. classrooms, students rehearse lockdown drills, learn the vocabulary of “active shooters,” and watch adults argue over the meaning of the Second Amendment while their own right to grow up safely remains unsettled. Teachers carry trauma as part of the job description, knowing that a typical school year now includes not only report cards and assemblies, but also the possibility of sirens, barricaded doors, and frantic messages to parents.

In Australia, students also live in an anxious world, but not one where school shootings have become a routine backdrop to education. The rarity of school gun attacks there allows children to focus their fears on more ordinary growing‑up worries instead of the layout of exits and hiding spots in their classrooms.

Policy choices, not destiny

The most unsettling truth is that none of this is inevitable. After the 1996 Port Arthur massacre, though not a school shooting, Australia chose to overhaul its gun laws, banning certain semi‑automatic weapons, launching a large‑scale buyback, and tightening licensing requirements nationwide. In the years since, mass shootings of all kinds, including those at schools, have become extraordinarily rare there, turning what used to be breaking news into historical memory.

The United States has taken the opposite path, responding to each massacre with familiar rituals of grief, political stalemate, and incremental safety measures inside schools rather than transformative limits on weapons outside them. Debates over universal background checks, secure firearm storage, age limits, and restrictions on high‑capacity weapons recur after each tragedy, but they have not yet produced the kind of unified, national response that could measurably change the trajectory of school gun violence.

Writing toward a different future

For anyone who cares about education, the steady drumbeat of school shootings is not just disturbing; it feels like an erosion of the social contract from within. To read that scores of American schools and campuses have already been scarred by gunfire this year is to confront the gap between what is promised to children and what is delivered when they walk through the school gate. The Australian example does not offer a perfect template, but it does prove that a wealthy democracy can, when pushed by public conscience, drastically reduce the risk that students will die in their classrooms.

AI Overview:What are the causes of school gun violence in the US


School gun violence in the United States stems from a mix of individual distress, social breakdown, and uniquely easy access to firearms, especially in homes. No single cause explains all incidents, but research points to a cluster of recurring risk factors that interact with one another.

Easy access to firearms

Studies show that the majority of guns used in K–12 school shootings come from the shooter’s own home or the home of relatives or friends. Adolescents often obtain firearms that are stored loaded or unsecured, and high levels of household gun ownership combined with permissive state gun laws are associated with higher rates of school shooting incidents.

Individual and psychological factors

Research on school shooters highlights histories of depression, suicidal thinking, emotional distress, and other mental health challenges, though most people with such conditions are not violent. A significant share of attackers report motives like revenge, bullying, persecution, or a desire for recognition, often alongside feelings of social isolation or grievance.

Family and childhood trauma

Family dysfunction, poor supervision, and exposure to domestic or community violence are strongly linked to later violent behavior, including gun-related violence. Many school shooters report childhood trauma such as abuse, loss of a parent, or chaotic home environments, which can fuel anger, impulsivity, and pessimism about life.

Peer, school, and social climate

Bullying, social rejection, and association with delinquent peers repeatedly emerge as key contributors in case studies and surveys. Low commitment to school, poor academic performance, and a school climate where students feel uncared for or unsafe can deepen alienation and make violent fantasies more appealing to some vulnerable youth.

Broader social and cultural factors

Community-level stressors, such as poverty, economic instability, and exposure to neighborhood violence raise the overall risk of youth violence, including in and around schools. At the same time, a wider culture that normalizes firearms, amplifies notoriety for shooters, and polarizes debates around guns and mental health creates an environment in which individual crises can more easily turn into armed attacks on schools.


Gun violence in U.S. schools and universities has 
increased significantly in frequency in recent years, with records set annually between 2021 and 2024 for the number of incidents. This violence has profound, long-term negative consequences for the mental health, academic achievement, and economic outcomes of student survivors. 
Key Statistics and Trends
  • Increasing Frequency: The number of school shooting incidents at K-12 schools has risen sharply. The 2023 count of 349 incidents was the highest on record, and 2024 saw similarly high numbers. As of November 2025, there have been over 200 incidents recorded by some databases for the year.
  • Casualties: Since the 1999 Columbine shooting, over 390,000 students have experienced gun violence at school. In 2024, there were 332 incidents resulting in 267 injuries and fatalities. While mass shootings (multiple fatalities) have not necessarily increased in frequency, they have become more deadly.
  • Leading Cause of Death: Gun violence is the leading cause of death for children and teens under the age of 20 in the United States.
  • Perpetrators and Weapon Access: Most perpetrators are current or former students who acquire their firearms from their homes or family members. An estimated 4.6 million children live in homes with at least one unlocked, loaded firearm.
  • Location: Most incidents occur in high schools, followed by middle schools. States with more permissive gun laws and higher rates of gun ownership tend to have higher rates of school shootings. 
Impact on Students and Education
The impact of gun violence in educational settings extends far beyond the immediate physical harm: 
  • Mental Health: Exposure to gun violence is linked to persistent increases in youth antidepressant use, anxiety, PTSD, and suicide risk. Nearly 60% of students worry a shooting could happen at their school.
  • Academic and Economic Outcomes: A 2024 study found that exposure to a school shooting reduces the likelihood of students graduating from high school and obtaining a bachelor's degree. Survivors are less likely to be employed and earn less annually over their careers.
  • School Environment: Concerns about safety lead to higher teacher turnover rates and difficulties in attracting educators to affected communities. 
Prevention and Policy
Prevention efforts are a subject of ongoing debate. 
  • School Hardening: Measures like security cameras, metal detectors, and active shooter drills are common, but research offers limited empirical evidence of their effectiveness in prevention and suggests they can negatively impact student mental health and school climate.
  • Gun Control Measures: Evidence-based solutions often proposed by advocacy groups include child access prevention (CAP) laws, universal background checks, and extreme risk laws. Studies have shown that CAP laws are associated with decreased rates of students bringing weapons to school. 
  • Finally, Key 2025 gun violence statistics to date include:
    —Total Injuries: 25,118.
    —Mass Shootings: 389 incidents (defined as 4+ victims shot, not including the shooter).
    —Mass Murders: 15 incidents.
    —Casualties Among Minors: 216 children (ages 0–11) and 968 teens (ages 12–17) have been killed.
    —School Shootings: Reports vary by definition; the K-12 School Shooting Database recorded 209 incidents resulting in 148 total victims (killed and wounded).
    —Unintentional Shootings: 1,255 incidents.
    —Defensive Gun Use: 1,092 recorded incidents.
