In 2023, more than 3 million Americans died. Most of those deaths came from just ten causes.
Chronic illness still dominates, but shifting numbers — including COVID’s collapse and suicide’s rise — show where the country’s health story is headed next.
Heart Disease

The undisputed number one. Nearly 681,000 deaths in 2023 — fueled by poor diets, sedentary lifestyles, and unequal access to care.
Cancer
A close second, with about 613,000 deaths. Even with cutting-edge therapies, cancer continues to stalk nearly every American family.
Accidents and Injuries
The third leading cause, with 222,000+ deaths. Car crashes, falls, and overdoses hit younger age groups hardest — a preventable toll.
Stroke
Cerebrovascular diseases killed 162,000 people in 2023. Progress in treatment hasn’t erased the risk.
Chronic Respiratory Illness
COPD and other lung diseases accounted for 145,000 deaths. Smoking, air quality, and chronic damage drive the numbers.
Alzheimer’s Disease
Brain health remains a massive challenge, with 114,000 deaths. An aging population keeps this number climbing.
Diabetes
About 95,000 deaths in 2023. Lifestyle, obesity, and access to preventive care make this a long-running crisis.
Kidney Disease
Roughly 55,000 deaths. Often overshadowed, but kidney failure is a quiet killer linked to hypertension and diabetes.
Liver Disease
Cirrhosis and chronic liver conditions took 52,000 lives, driven by alcohol, hepatitis, and obesity.
COVID-19 and Suicide
COVID fell to 49,900 deaths in 2023, sliding out of the top ten by 2024. Suicide took its place — a stark signal about mental health in America.
Prediction
Chronic disease will keep leading the charts, but mental health and addiction are fast becoming the front line. Expect policy to tilt toward prevention, with heart disease and cancer still top priorities, but suicide and overdoses demanding urgent new attention.
