Crime and Guns: What Does the Data Actually Say?
Few topics in American life are more contentious than guns and crime. Both sides cherry-pick statistics. This analysis presents the data — all of it — and lets the numbers speak. We draw from FBI homicide data, CDC mortality statistics, state-level gun ownership estimates, and international comparisons. Our goal is not to advocate for any policy position, but to present what the evidence actually shows.
Key Insights
- →Firearms are involved in approximately 77% of US homicides
- →Handguns account for ~59% of gun homicides where weapon type is known
- →The US gun homicide rate is ~25x higher than other high-income countries
- →States with highest gun ownership don't always have the highest gun crime
- →Rifles (including "assault weapons") account for ~3% of gun homicides
- →Two-thirds of gun deaths are suicides, not homicides
The Scale of Gun Violence in America
In a typical year, approximately 45,000 Americans die from firearms. But that headline number obscures a critical distinction:
Most gun deaths are suicides, not homicides. This is critically important for policy discussions because the interventions for preventing suicide are very different from those for preventing homicide. Approximately 85% of suicide attempts with a firearm are fatal, compared to ~5% with other methods — suggesting that access to firearms may significantly affect suicide completion rates.
When people say "gun violence," they usually mean homicide. But the suicide toll is actually larger — and often ignored in the debate.
Murder Weapons: What the FBI Data Shows
FBI Supplementary Homicide Reports provide detailed weapon data for murders. Here's the breakdown:
| Weapon Type | Homicides | % of Total |
|---|---|---|
| Handguns | 6,246 | 22.7% |
| Firearms (type not stated) | 4,565 | 16.6% |
| Rifles | 401 | 1.5% |
| Shotguns | 149 | 0.5% |
| Other guns | 356 | 1.3% |
| Total Firearms | 11,717 | 42.6% |
| Knives/Cutting Instruments | 1,566 | 5.7% |
| Personal Weapons (hands, fists) | 633 | 2.3% |
| Blunt Objects (clubs, hammers) | 283 | 1.0% |
| Other/Not Stated | 1,400 | 5.1% |
The Rifle Reality
Rifles — the category that includes AR-15s and other so-called "assault weapons" — account for approximately 401 homicides, or about 1.5% of all murders. More people are killed with knives (1,566), personal weapons like hands and feet (633), and blunt objects (283) than with rifles. This doesn't mean rifles aren't involved in high-profile mass shootings — they are. But in terms of total homicide volume, handguns are overwhelmingly the weapon of choice.
Handguns are the primary murder weapon in America. Where weapon type is known, handguns outnumber rifles roughly 15-to-1 in homicides. The "assault weapon" debate, while emotionally charged, addresses a small fraction of overall gun violence.
Gun Ownership Rates vs Violent Crime
Does more gun ownership lead to more crime? The answer is not straightforward. Using RAND survey data on gun ownership and FBI crime statistics:
| State | Gun Ownership | Violent Crime Rate | Homicide Rate |
|---|---|---|---|
| Montana | 66% | 469.8 | 5.0 |
| Wyoming | 66% | 234.1 | 3.1 |
| Alaska | 65% | 724.1 | 6.9 |
| Idaho | 60% | 242.6 | 2.5 |
| West Virginia | 59% | 355.8 | 5.4 |
| New Hampshire | 41% | 146.4 | 1.1 |
| Massachusetts | 14% | 308.8 | 2.4 |
| New Jersey | 12% | 195.4 | 3.1 |
| Hawaii | 9% | 280.6 | 2.8 |
| New York | 19% | 363.7 | 3.6 |
The correlation is weak and inconsistent. Wyoming has one of the highest gun ownership rates (66%) but a relatively low violent crime rate. Alaska has high ownership AND high violence. New Hampshire has moderate ownership and very low crime. Massachusetts has very low ownership but moderate crime.
This suggests that gun ownership alone is not the primary driver of violent crime. Other factors — poverty, urbanization, gang activity, drug markets, social cohesion — appear to be stronger predictors. However, this doesn't mean guns have no effect on crime outcomes. The lethality of crime is clearly affected by firearm availability.
The Nuance
Gun ownership may not predict whether someone will commit a crime, but it strongly predicts whether a violent encounter will be fatal. An aggravated assault with a gun is far more likely to become a homicide than one with a knife or fists. The presence of firearms doesn't create criminals — but it makes violent encounters more deadly.
Strict vs Permissive Gun Law States
States are often divided into "strict" and "permissive" gun law categories. Comparing crime rates between them is illuminating — but complicated:
Strictest Gun Laws
- California: Violent rate 486.0, Homicide 4.5
- New York: Violent rate 363.7, Homicide 3.6
- New Jersey: Violent rate 195.4, Homicide 3.1
- Massachusetts: Violent rate 308.8, Homicide 2.4
- Hawaii: Violent rate 280.6, Homicide 2.8
- Average homicide: ~3.3 per 100K
Most Permissive Gun Laws
- Mississippi: Violent rate 291.2, Homicide 13.9
- Louisiana: Violent rate 519.8, Homicide 10.8
- Alabama: Violent rate 453.4, Homicide 8.7
- Missouri: Violent rate 495.0, Homicide 9.8
- Arkansas: Violent rate 579.4, Homicide 7.3
- Average homicide: ~10.1 per 100K
States with stricter gun laws generally have lower homicide rates — but they also tend to be wealthier, more urban, and have different demographic profiles. Disentangling the effect of gun laws from poverty, urbanization, and other factors is methodologically challenging.
Both sides have a point: Gun control advocates are correct that strict-law states have lower homicide rates. Gun rights advocates are correct that many factors beyond gun laws drive these differences. The honest answer is that gun laws likely have someeffect, but they're far from the only — or even the primary — determinant of crime rates.
International Comparison
The US gun homicide rate stands out starkly among high-income peer nations:
| Country | Gun Homicide Rate | vs US |
|---|---|---|
| United States | 4.12 | — |
| Canada | 0.52 | 8x lower |
| Australia | 0.15 | 27x lower |
| United Kingdom | 0.04 | 103x lower |
| Germany | 0.06 | 69x lower |
| France | 0.12 | 34x lower |
| Japan | 0.01 | 412x lower |
The US gun homicide rate is approximately 25 times higher than the average of other high-income countries. This is the single most striking statistic in the guns-and-crime debate. It doesn't prove causation — America differs from these countries in many ways beyond gun policy — but the gap is enormous and difficult to explain without accounting for firearm availability.
However, America's non-gun homicide rate is also higher than most peer nations, suggesting that factors beyond firearms contribute to America's violence problem.
The Handgun vs "Assault Weapon" Distinction
Much of the political debate focuses on so-called "assault weapons" — typically semi-automatic rifles like the AR-15. But the data tells a different story about where gun violence actually occurs:
Handguns kill 15 times more people than rifles in America. The focus on "assault weapons" in the political debate is driven by mass shootings — which are horrifying but statistically rare. The daily toll of gun violence is overwhelmingly a handgun problem, concentrated in specific urban neighborhoods with high poverty and gang activity.
This doesn't mean assault weapon restrictions have no merit — mass shootings cause immense psychological harm beyond the body count. But if the goal is reducing total gun homicides, handgun policy matters far more than rifle policy.
What the Evidence Says Works
Setting aside political ideology, what does the evidence suggest actually reduces gun violence?
- Focused deterrence / violence interruption: Programs like CeaseFire/CURE Violence that target specific high-risk individuals have shown 30-60% reductions in shootings in multiple cities.
- Extreme risk protection orders (red flag laws): Evidence suggests these prevent some suicides and potentially some mass shootings, though data is limited.
- Universal background checks: States with universal background checks have ~15% lower firearm homicide rates, though causation is debated.
- Hospital-based violence intervention: Programs that reach shooting survivors in the hospital reduce re-injury rates by 60-70%.
- Addressing root causes: Poverty reduction, employment programs, mental health access, and community investment reduce violence regardless of gun policy.
The Bottom Line
The guns-and-crime relationship is real but complicated. Firearms don't cause crime — poverty, inequality, drug markets, and gang activity are stronger predictors of violence. But firearms make violent encounters far more lethal, and America's gun homicide rate is an extreme outlier among wealthy nations.
The most effective approaches address both gun access (for high-risk individuals) and root causes of violence simultaneously. Neither "more guns" nor "ban all guns" reflects what the data actually supports.
The data is clear on one thing: America's gun violence problem is overwhelmingly a handgun problem, concentrated in specific communities, driven by specific risk factors, and addressable through targeted interventions — if we have the political will.
