The same dataset produces 99 or 10,580 incidents depending on how you define the term
The Congressional Research Service analyzed Gun Violence Archive data from 2014–2023 and found that the number of "mass shootings" ranges from as few as 99 to as many as 10,580 depending on which of 12 different definitions you apply. That's a 100× range from the same underlying data.
When advocacy groups cite thousands of mass shootings per year, they're using a definition that counts any incident where four or more people are shot — including gang crossfire, drug deals, and bar fights. When researchers study the phenomenon that terrifies Americans — a stranger walking into a school, church, or public venue and opening fire — the count drops to roughly 10 per year.
It's not about race, religion, or gender identity. It's about a four-step pathway to suicide-by-mass-murder.
The Violence Project — the most comprehensive mass shooter database in the country, funded by the Department of Justice — coded over 160 life-history variables for every public mass shooter since 1966. There is no single demographic profile. But there is a pathway that nearly all of them share.
Early Childhood Trauma
Physical abuse, sexual abuse, parental suicide, domestic violence, or severe bullying. For K-12 school shooters, 68% experienced severe childhood trauma.
An Identifiable Crisis Point
Job loss, expulsion, breakup, public humiliation. Over 80% were in a noticeable crisis before the shooting — and they communicated it to people around them through a marked change in behavior.
Radicalization & Validation
They find inspiration in past shooters and seek validation online. Extremist communities provide belonging that the shooter lacks — the ideology matters less than the sense of community.
The Means to Act
Access to firearms. 77% used handguns. 77% obtained guns legally. Young school shooters typically stole guns from family members.
The critical finding: these are fundamentally suicide events. 30% were suicidal before the shooting. Another 39% became suicidal during it. For school shooters: 92%. For college shooters: 100%. They don't expect to survive. They've decided life isn't worth living and they want to take people with them.
Different venues, different shooters — but the same underlying crisis
K–12 School
White male student of the school. History of trauma. Suicidal. Leaked plans ahead of time. Used multiple guns stolen from a family member.
College / University
Non-white male student. History of childhood trauma. Suicidal. Used legally obtained handguns. Left a video or manifesto.
Workplace
Male in his 40s, no racial profile. Employee of a blue-collar site. Having trouble at work. Used handguns and rifles he legally owned.
House of Worship
White male in his 40s. Motivated by domestic issues or hate. Criminal record and violent history. Used legally owned handguns or assault rifles.
Mass shooters are getting younger. Fast.
The median age of mass shooters has collapsed from 39 to 22 over four decades. Seven of the ten deadliest mass shootings were committed by people in their 20s. Something is happening to young men in America — and it's getting worse, not better.
While we debate 99 mass shootings, nearly 18,000 gun homicides happen every year — and we've collectively closed our eyes
In 2023, there were approximately 17,900 gun homicides in the United States. The vast majority weren't mass shootings in schools or churches. They were young men killing other young men in America's inner cities — overwhelmingly with handguns, overwhelmingly connected to gang feuds, drug markets, and cycles of retaliatory violence.
The numbers are staggering: despite making up roughly 6% of the total U.S. population, Black boys and men account for more than half of all gun homicide victims. For Black men ages 15 to 24, gun homicide is the leading cause of death — exceeding the next 15 causes of death combined. The firearm homicide rate for Black boys ages 15 to 19 is 92 per 100,000, compared to 3.25 for their white counterparts. That's a 28-to-1 ratio.
Research consistently shows this violence is remarkably concentrated. In Boston, gang members represented less than 1% of all youth but were connected to nearly two-thirds of youth gun murders. In Minneapolis, roughly 2,650 people in 32 street gangs — less than 3.5% of residents aged 14 to 24 — were central to nearly all youth gun violence. The problem isn't diffuse. It's identifiable, concentrated, and — as we proved in the 1990s — solvable.
We solved this before
In the 1990s, programs like Boston's Operation Ceasefire, the COPS (Community Oriented Policing Services) initiative, and targeted community intervention programs drove violent crime down dramatically. Homicide rates in major cities dropped 40-60% between 1993 and 2001. It worked because it combined law enforcement with community investment — jobs programs, mentorship, outreach workers who were former gang members, and direct engagement with the small number of people driving the violence.
Then we stopped funding it. Attention moved elsewhere. And the violence came back — surging during the pandemic to levels not seen in decades. The FBI reported over 69,000 gang-related incidents from 2021 to 2024 alone, with most offenders aged 13 to 16. We know what works. We just stopped doing it.
Both sides use these deaths when it's convenient and ignore them when it's not. The left lumps them into "mass shooting" statistics to inflate the numbers for gun control arguments. The right dismisses them as "gang violence" and moves on — as if a 16-year-old dead in Chicago matters less than a 16-year-old dead in a suburb. Every one of those 18,000 annual gun homicides is a person. Most of them are young. Most of them are in communities that have been asking for help for decades.
And then there's the largest category of all — the one almost nobody talks about
In 2023, 27,300 Americans died by gun suicide — 58% of all gun deaths. That's more than all gun homicides combined. More than all mass shootings in the last decade combined, multiplied by a hundred. Suicides have accounted for the majority of gun deaths in nearly every year on record, and they hit a peak in 2023. Yet they are virtually absent from the national gun debate.
The pattern is grimly consistent: gun suicides are overwhelmingly male (nearly 87%), disproportionately white, and increasingly concentrated among middle-aged and older men — particularly veterans and rural Americans. Access to a firearm dramatically increases the likelihood that a suicide attempt will be fatal. Roughly 85% of suicide attempts with a gun result in death, compared to less than 5% for most other methods. A momentary crisis becomes permanent when a gun is within reach.
The left avoids talking about gun suicide in detail because the demographic profile — white, male, rural, gun-owning — doesn't fit the narrative they want to tell. The right avoids it because any policy response might imply restricting gun access, which is a non-starter. So 27,000 people a year die in the gap between two political positions, and neither side will look directly at it.
The real breakdown of ~47,000 annual gun deaths in America
Source: CDC, 2023 · Of the 38% homicides, the majority are young men in inner cities. Of the 58% suicides, the majority are older white men in rural areas.
Indiscriminate public mass shootings account for roughly 10-15 deaths per year — less than 0.03% of the total.
We verify identity for money. We refuse to verify it for children.
The mass shooter pathway runs through online radicalization. Isolated, traumatized young men find communities that validate violence and provide blueprints for murder. This is the step that didn't exist at scale 25 years ago — and it's the one we could actually address.
We put a man on the moon before most Americans were born. We run real-time fraud detection across billions of financial transactions daily. The idea that Silicon Valley cannot verify whether a user is 13 or 30 is not a technology problem. It's a business model problem.
What We Verify Online
- Bank account access
- Stock trades
- Tax filings
- Alcohol and tobacco purchases
- Prescription drug orders
- Real estate transactions
What We Don't Verify
- A 10-year-old accessing graphic violence
- A 12-year-old in extremist forums
- A 14-year-old consuming pornography
- A 15-year-old studying past mass shooters
- A teenager in pro-self-harm communities
- Any child's age on any platform
Three companies — Apple, Google, and Microsoft — control the operating systems on virtually every device in America. A device-level age verification token, verified once, checked by apps and sites without transmitting identity data, could be implemented tomorrow. The reason it hasn't been built isn't that it's hard. It's that a 14-year-old scrolling for four hours a day is a revenue-generating user, not a child to protect.
"This is not a gun debate or a mental health debate. It is a debate about whether we are willing to protect children from the machinery that profits from their attention."
The Bottom Line
The mass shooting problem is real but deliberately miscounted. The profile is known but politically inconvenient for both sides. The online radicalization pipeline is the accelerant — and the fix is not censorship, it's the same age-appropriate gatekeeping we already apply to alcohol, driving, and financial transactions. We have the technology. We lack the will — because the will threatens the revenue.
