Does keeping a gun in the home make a household safer?
Our take
Homes with guns show higher suicide risk, and often higher homicide risk. How often guns are used defensively is still badly measured.
Why we say this
NEJM, 1993
Keeping a gun in the home was associated with higher homicide risk in the home.
CDC, 2022
Reducing access to lethal means, including firearms, is an evidence-informed suicide-prevention strategy.
JAMA Network Open, 2025
Among adults with firearm access, fewer than 1% reported any defensive gun use in the past year.

Where the claims stand
This story tracks empirical evidence on whether firearm ownership or keeping a gun in the home reduces or increases the risk of injury or death to household members. The question concerns population-level associations in observational research, not individual cases or constitutional questions about gun ownership rights.

Additional information
Status
as of July 31, 2026Several core empirical claims are supported by peer-reviewed or official sources: household firearm access is associated with higher suicide risk across multiple sources, and a major case-control study linked home guns to higher in-home homicide risk. A 2025 survey found defensive gun use uncommon among adults with firearm access. What remains unsettled is net household safety in every circumstance, the precise population-level frequency of defensive gun use across survey methods, and how much confounding, storage, and household context change individual risk. There is no randomized trial of household gun ownership.
Confidence — current state
Multiple peer-reviewed studies and official mortality data show higher firearm death rates in homes with guns, particularly for suicide. On defensive gun use, a 2025 JAMA Network Open survey of U.S. adults with firearm access found that most respondents reported no lifetime defensive use and that past-year use was rare, while historical survey-based frequency estimates still vary widely across methods. The evidence supports associations at the population level but does not by itself determine outcomes for any specific household or individual situation.
This is our best read given the published evidence we have reviewed — not a claim of absolute truth.
Open questions
How often do defensive gun uses occur, and how many injuries or deaths do they prevent?
Recent survey data among firearm owners finds defensive use uncommon, but population-level annual estimates still vary widely by method, and prevented-harm counts remain hard to measure.
How much do differences in storage practices, household composition, and local crime rates change risk?
Most studies estimate average associations rather than individualized risk.
How should observational associations be interpreted given that gun ownership is not randomly assigned?
Confounding remains a central methodological challenge.
What would change our mind
- Large, well-designed prospective studies with improved confounding control producing consistent opposite findings.
- Reliable independent datasets documenting defensive gun uses at a scale that materially changes net household risk estimates.
- Updated systematic reviews overturning current major association findings.
Claims & evidence
Each claim is tracked separately — not a single verdict.A major case-control study found that keeping a gun in the home was associated with a higher risk of homicide in the home.
Evidence basis- October 7, 1993Gun Ownership as a Risk Factor for Homicide in the Home
Kellermann and colleagues reported that guns in the home were associated with increased homicide risk, especially among family members and acquaintances.
Multiple studies have found that access to firearms in the home is associated with higher risk of suicide, especially among household members.
Evidence basis- January 1, 2022Suicide Prevention Resource for Action
CDC guidance notes that reducing access to lethal means, including firearms, is an evidence-informed suicide prevention strategy.
- August 13, 1992Suicide in the Home in Relation to Gun Ownership
Kellermann and colleagues reported higher suicide risk in homes with guns compared with matched homes without guns.
Estimates of how often guns are used defensively vary widely across studies, and the evidence does not establish a precise, uncontested frequency.
Evidence basis- January 1, 2005Firearms and Violence: A Critical Review
The National Research Council reported survey estimates ranging from roughly 100,000 to 2.5 million or more defensive gun uses per year—differing by a factor of 20 or more—due to disagreements over definition and measurement.
- March 14, 2025Lifetime and Past-Year Defensive Gun Use
The authors note that no consensus exists on how frequently defensive gun use occurs, even as their survey finds it rare among adults with firearm access.
A 2025 survey of U.S. adults with firearm access found that defensive gun use was uncommon: most respondents reported none over their lifetime, fewer than 1% reported any form in the past year, and gun violence exposure was more common.
Evidence basis- March 14, 2025Lifetime and Past-Year Defensive Gun Use
Among 3,000 adults with firearm access, 91.7% reported no lifetime defensive gun use; less than 1% reported any form of past-year defensive use, while gun violence exposure was more pervasive.
What this doesn’t establish
Claims commonly associated with this story that the available evidence does not establish. Confirming a narrow fact here is not confirmation of the broader narrative around it. As such, these claims are not included in the claims bar above.
Current evidence establishes that keeping a gun in the home uniformly makes households safer.
Evidence basis- October 7, 1993Gun Ownership as a Risk Factor for Homicide in the Home
The study reported higher associated homicide risk in homes with guns rather than uniform protective effects.
- March 14, 2025Lifetime and Past-Year Defensive Gun Use
Self-reported defensive gun use was rare among adults with firearm access relative to gun violence exposure, which does not support uniform protective effects from household firearm access.
Current evidence establishes that keeping a gun in the home uniformly makes every household less safe in every circumstance.
Evidence basis- January 1, 2005Firearms and Violence: A Critical Review
The report documents large, unresolved gaps in measuring defensive gun use and does not establish uniform household safety outcomes from firearm access.
How we got here
5 updates · append-onlyJAMA Network Open survey finds defensive gun use rare among firearm owners
A nationally drawn 2024 survey of 3,000 U.S. adults with firearm access, published in JAMA Network Open in 2025, reported that 91.7% had no lifetime defensive gun use and that fewer than 1% reported any form of past-year defensive use, while gun violence exposure was more common. The authors conclude that narratives centering defensive use may misstate the risk profile of firearm access. Absolute population-level frequency estimates across study designs remain debated.

CDC suicide prevention guidance treats firearm lethal-means access as a key risk factor
CDC’s Suicide Prevention Resource for Action summarizes evidence that reducing access to lethal means—including firearms—is an evidence-informed prevention strategy, corroborating earlier household-level findings that firearm access is associated with higher suicide risk.
What changed
- Claim: home firearm access and suicide risk: supported corroborated

The National Research Council report Firearms and Violence: A Critical Review found survey estimates of defensive gun use ranging from roughly 100,000 to 2.5 million or more per year, differing by a factor of 20 or more because of disagreements over definition and measurement, complicating net household safety claims.

Kellermann study links home guns to higher in-home homicide risk
A subsequent NEJM study found that keeping a gun in the home was associated with increased homicide risk in the home, especially among family members and acquaintances.
What changed
- Homicide association evidence: Suicide-focused studies only In-home homicide association reported
