More Americans than ever now live long enough to retire. But even as longevity improves, certain risks continue to shape what later life looks like.
According to data from the Centers for Disease Control and Prevention (CDC), 10 causes account for roughly 1.7 million deaths a year among people aged 65 or older, or about 1 in 32 seniors.
Each death is recorded under a single primary cause, even when other conditions contribute. Many of these diseases overlap, but each is counted only once in federal statistics.
These figures are drawn from the most recent complete dataset (2019) in the CDC’s WONDER database, which tracks national mortality by cause and age group. More recent CDC summaries, including Mortality in the United States, 2023, show that the same leading causes remain at the top for older adults, with only small year-to-year changes in ranking or rate.
1. Heart disease
Heart disease causes the death of about 1 in 102 older Americans each year (531,583 people). High blood pressure, cholesterol, diabetes, and inactivity are the main contributors.
You can lower your risk by managing blood pressure, staying physically active, eating more fruits and vegetables, and keeping your weight in check. Regular checkups can detect changes early.
2. Malignant neoplasms (cancer)
Cancer claims the lives of about 1 in 124 older Americans each year (435,462 people). The most common forms are lung, colorectal, breast, and prostate cancer.
Screening and early detection save lives. Ask your doctor about screening schedules that fit your age and health history, and keep up with vaccinations that reduce cancer risk, such as those for HPV and hepatitis B.
3. Chronic lower respiratory diseases
Chronic lung diseases, including COPD, emphysema, and chronic bronchitis, lead to the deaths of about 1 in 406 older Americans each year (133,246 people).
Avoid smoking, limit exposure to pollution, and get regular lung screenings if you’ve ever smoked heavily. Pulmonary rehab and breathing exercises can improve quality of life even after diagnosis.
4. Stroke (cerebrovascular diseases)
Stroke takes the lives of about 1 in 418 older Americans each year (129,193 people). Risk rises sharply with high blood pressure, diabetes, and heart disease.
You can reduce your risk by keeping your blood pressure under control, watching your diet, and exercising regularly. Know the early signs of stroke — sudden weakness, confusion, or slurred speech — and seek immediate help if they appear.
5. Alzheimer’s disease
Alzheimer’s disease results in the death of about 1 in 450 older Americans each year (120,090 people). It is one of the fastest-growing causes of death as Americans live longer.
There’s no cure, but early diagnosis helps families plan and connect with resources. Physical activity, good sleep, and social engagement may help slow decline.
6. Diabetes mellitus
Diabetes leads to the deaths of about 1 in 867 older Americans each year (62,397 people). It often appears alongside heart disease and kidney problems.
You can manage it with a balanced diet, consistent exercise, and medication if needed. Routine blood sugar checks and annual A1C tests are essential for long-term control.
7. Unintentional injuries (mostly falls)
Falls kill about 1 in 893 older Americans each year (60,527 people). The death rate from falls has nearly doubled since 2000.
Most fatal falls happen at home. Reduce risk by removing tripping hazards, adding handrails and non-slip mats, and doing exercises that strengthen balance and leg muscles.
8. Chronic kidney disease
Chronic kidney disease causes the death of roughly 1 in 1,280 older Americans each year (42,230 people). It often develops from long-term high blood pressure or diabetes.
Drink enough water, avoid excessive salt and NSAID painkillers, and get regular kidney function tests if you have diabetes or hypertension.
9. Influenza and pneumonia
Influenza and pneumonia claim about 1 in 1,337 older Americans each year (40,399 people). Both illnesses can become life-threatening when age or chronic conditions weaken the immune system.
The best protection is prevention. Annual flu shots, pneumonia vaccines, and prompt treatment for respiratory infections reduce the risk of severe complications. Maintaining good nutrition and regular medical checkups also supports immune health.
10. Parkinson’s disease
Parkinson’s disease contributes to the deaths of about 1 in 1,570 older Americans each year (34,435 people). It is a progressive neurological disorder that affects movement, balance, and muscle control. While it is not always fatal on its own, complications such as falls or pneumonia often play a role.
Early diagnosis and consistent management can slow progression and improve quality of life. Physical therapy, medication, and specialist care help preserve mobility and independence for as long as possible.
Actionable longevity: Managing risk
The leading causes of death among older Americans may look like fate, but they are heavily influenced by two things: early detection and financial preparation. This is about proactive defense, not simply reacting to a diagnosis or crisis.
- Prioritize movement and sleep. Regular activity, balance training, and social connections reduce risk for heart disease, stroke, diabetes, and cognitive decline. Strength and balance exercises help prevent fatal falls, one of the fastest-growing threats to seniors.
- Screen for health risks. Routine tests for heart disease, cancer, and diabetes catch trouble early when treatment costs less and works better. Do not skip checkups or delay recommended screenings based on age or family history. Life Line Screening reveals hidden risks so you can act early. Book a screening today.
- Audit your insurance. Review your Medicare or supplemental plan to understand deductibles, out-of-network limits, and long-term care coverage. Know what is included and what is not before an emergency happens.
- Save for care, not just retirement. Medical costs rise faster than inflation. Build a separate fund for home care, skilled nursing, or other specialized help to protect core retirement savings from being drained by a health crisis.
- Finalize legal directives. Update your will, durable power of attorney, and advance medical directives now. Clear documents reduce confusion, cost, and conflict if quick decisions are needed later.
The goal is to outlive current statistics and to do it well. A realistic plan for health, money, and legal protection gives you the best chance to remain independent, stay healthy, and live on your own terms.
