The evidence behind the actions
U.S. primary government sources, checked September 21, 2026. Data years are stated separately from page update dates.
Home hazards and place of death are different
Heart disease and cancer lead all U.S. deaths: 683,491 and 619,876 respectively in 2024. Those are national totals across all locations. CDC source
A current comparable ranking of deaths specifically inside homes was not verified. A home injury can lead to a hospital death; an illness can end at home. This guide covers practical prevention, not a measured ranking of home-death causes.
Two major unintentional injury causes
U.S. deaths, all ages and all locations, 2024. These are NOT home-only counts. CDC/NCHS
No categories are added together. Carbon monoxide overlaps with poisoning; infant sleep-related suffocation is not the same as all sudden unexpected infant deaths. Some undated estimates are omitted.
Full prevention guide
Medicines & substancesPoisoning and overdose
75,761
Unintentional poisoning deaths, U.S., 2024, all locations. This includes more than medicines. [2]
- Use prescription medicines only when prescribed to you; follow all medicine labels. Check for duplicate active ingredients and use the supplied dosing device for children.
- Close safety caps and put medicines away after every use, somewhere children cannot see or reach.
- Keep naloxone available when opioid overdose is a risk. For a suspected opioid overdose, give it if available, call 911 and stay with the person. Connect someone with opioid use disorder to treatment.

Especially age 65+Falls
48,308
Unintentional fall deaths, U.S., 2024, all locations. [2]
- Clear the route from bed to bathroom. Move cords, shoes and clutter; remove loose rugs or secure them with non-slip backing.
- Make steps and nighttime trips easier to see. Fix uneven stairs, replace dead bulbs and add nightlights.
- Add bathroom support: properly installed grab bars and non-slip tub or shower surfaces.

Support + safe storageSuicide and firearm access
48,824
Suicide deaths, U.S., 2024, all methods and locations. Not a firearm-only count. [1]
- Store firearms locked and unloaded; secure ammunition separately. Hiding a gun or placing it high up is not secure storage.
- Reduce access to dangerous items during a crisis, including medications and firearms, and involve trusted support and professional help.
- Call or text 988 for suicide or mental-health crisis support. Call 911 for a life-threatening emergency.

Every householdFire and smoke
Test alarms monthly
USFA's current pages mix 2024 fire counts and older death tables. No current residential death count is claimed here. [7]
- Put smoke alarms inside every bedroom, outside sleeping areas and on every level. Test them monthly. Replace alarms at 10 years.
- Plan two ways out of every room, keep exits clear and choose an outdoor meeting place.
- Practice the escape plan with everyone in the home. Plan help for people who cannot get out independently.
USFA smoke-alarm and escape-plan guidance. [7]
Invisible gasCarbon monoxide
Alarms + distance
CO has no color or smell. It is also a poisoning hazard, so it must not be added to poisoning as an independent total. [8]
- Install battery-powered or battery-backup CO alarms near every sleeping area. Have fuel-burning equipment serviced annually.
- Run generators outdoors, more than 20 feet from doors, windows and vents. Never inside a home or garage, even with the door open.
- Never burn charcoal indoors. An open window does not make indoor combustion safe.
CDC and CPSC guidance. [8]
Especially young childrenDrowning
Ages 1-4
Drowning is the leading cause of death in this age group nationwide, across locations. [9]
- Give children constant, close adult supervision around water, including bathtubs and buckets. Do not rely on swimming ability alone.
- Separate a pool from the house and yard with a four-sided fence and self-closing, self-latching gate.
- Learn CPR and water safety. Use multiple protections: a fence cannot replace an attentive adult.

Babies under age 1Sleep-related suffocation
947
U.S. infant deaths classified as accidental suffocation and strangulation in bed, 2024. Not all sudden infant deaths are suffocation. [11]
- Put babies on their back for every sleep, including naps.
- Use a firm, flat infant sleep surface with a fitted sheet. Keep pillows, loose blankets, bumpers and soft toys out.
- Share your room, not your bed. Keep the baby's separate crib or bassinet nearby, ideally for at least the first six months.

Young children eatingChoking
Sit. Prepare. Watch.
No current home-only death count verified for this report.
- Keep young children seated upright while eating. Watch throughout meals and snacks.
- Match food texture and size to their development. Cut or mash foods; avoid whole grapes, nuts, popcorn and hard or sticky foods.
- Learn an age-appropriate choking response from a clinician or first-aid instructor before an emergency happens.
CDC choking prevention, updated March 2026. [13]
Long-term exposureRadon and lung cancer
Test the home
A smoke or CO alarm does not substitute for a radon test.
- Test for radon, even without a basement. You cannot see or smell this radioactive gas.
- At 4 pCi/L or higher, arrange professional mitigation. Retest after the work to check that levels fell.
EPA's widely cited "about 21,000 deaths" is a historical model estimate: a 2003 analysis of 1995 lung-cancer deaths. It is not a newly measured 2026 count, so it is not plotted beside recent death totals.
EPA guidance, updated April 2026. [14]
Beyond home hazardsHeart disease
683,491
U.S. deaths in 2024, all locations. The leading national cause of death. [1]
- Know your blood pressure and cholesterol. Work with your clinician to control them and manage diabetes if present.
- Avoid smoking and make regular activity and healthy eating part of the routine. These address major heart-disease risk factors.
- Get emergency help for possible heart-attack symptoms. Chest discomfort, shortness of breath, upper-body pain, nausea, dizziness or unusual fatigue can be warning signs.
