How Will I Die? The Most Common Causes for People Like You
No calculator can know how one person will die. What we can show is how people of your age, sex and country most often die, from World Health Organization statistics. For adults worldwide, heart disease and stroke are the leading causes, and many of the top causes are strongly linked to smoking, weight, blood pressure and activity.
Pick your country, age group and sex to see the five leading causes of death for that group. These are shares of all deaths in the group, not your personal odds. For when, rather than how, use the death clock calculator.

What are the most common causes of death in adults?
Across the 183 countries in WHO’s Global Health Estimates, these were the leading causes of death among people aged 15 and over in 2021:
| Rank | Cause | Share of adult deaths |
|---|---|---|
| 1 | Ischaemic heart disease (heart attacks and blocked heart arteries) | 14.5% |
| 2 | COVID-19 | 13.9% |
| 3 | Stroke | 11.2% |
| 4 | Chronic obstructive pulmonary disease (COPD) | 5.6% |
| 5 | Lung cancer (trachea, bronchus and lung) | 3.0% |
| 6 | Alzheimer disease and other dementias | 2.9% |
| 7 | Lower respiratory infections, such as pneumonia | 2.7% |
| 8 | Diabetes | 2.6% |
| 9 | Hypertensive heart disease (from high blood pressure) | 2.2% |
| 10 | Kidney diseases | 2.2% |
2021 was a pandemic year, which is why COVID-19 ranks so high. WHO’s 2021 estimates are the latest full set by country, age and sex. In later years COVID-19 deaths fell sharply in most countries, so heart disease and stroke are now even further ahead.
How do causes of death change with age?
The pattern changes a lot across a lifetime. Young adults mostly die from injuries. From middle age, chronic diseases take over.
| Age group | Men | Women |
|---|---|---|
| 15 to 29 | Road injury 16.0%, interpersonal violence 12.5%, self-harm 8.1% | Maternal conditions 15.2%, self-harm 7.4%, COVID-19 7.1% |
| 30 to 49 | COVID-19 16.9%, ischaemic heart disease 8.9%, road injury 7.1% | COVID-19 14.4%, ischaemic heart disease 6.2%, maternal conditions 6.0% |
| 50 to 69 | COVID-19 17.4%, ischaemic heart disease 14.5%, stroke 9.7% | COVID-19 14.0%, ischaemic heart disease 12.3%, stroke 10.9% |
| 70 and over | Ischaemic heart disease 16.3%, COVID-19 14.4%, stroke 12.8% | Ischaemic heart disease 17.5%, stroke 14.1%, COVID-19 11.3% |
Two things stand out. Among young men, road crashes and violence lead. Among young women worldwide, complications of pregnancy and childbirth are still the top cause, mostly in countries with weaker maternal care. After 50, heart disease and stroke dominate for everyone.
Causes of death at 50 to 69 in different countries
| Country | Men | Women |
|---|---|---|
| United States | Ischaemic heart disease 16.4%, COVID-19 15.5%, lung cancer 4.9% | COVID-19 15.7%, ischaemic heart disease 10.3%, lung cancer 6.3% |
| United Kingdom | Ischaemic heart disease 15.7%, COVID-19 8.7%, lung cancer 7.7% | Lung cancer 9.9%, breast cancer 8.2%, ischaemic heart disease 7.2% |
| Canada | Ischaemic heart disease 16.4%, lung cancer 8.8%, COVID-19 5.3% | Lung cancer 12.6%, breast cancer 8.1%, ischaemic heart disease 7.9% |
| India | COVID-19 29.7%, ischaemic heart disease 15.3%, COPD 6.3% | COVID-19 17.5%, ischaemic heart disease 14.0%, stroke 8.5% |
| Pakistan | Ischaemic heart disease 21.0%, COVID-19 13.2%, stroke 9.3% | Ischaemic heart disease 19.5%, stroke 11.7%, COVID-19 9.4% |
| Nigeria | Tuberculosis 11.5%, stroke 11.1%, ischaemic heart disease 10.9% | Tuberculosis 12.6%, ischaemic heart disease 10.8%, stroke 10.0% |
In the UK and Canada, cancers lead for women in this age group. In Pakistan, heart disease takes a larger share than in most countries. In Nigeria, tuberculosis is still a leading cause in middle age, a reminder that infections remain a major risk in many places.
How do causes of death differ by country?
A lot. In high-income countries, most deaths happen at older ages, from heart disease, stroke, dementia and cancers. In many lower-income countries, infections, maternal conditions and injuries still cause a larger share of deaths at younger ages. Use the tool above to compare your country with others. Our life expectancy by country page shows how these differences add up to gaps of 30 years or more.
What lowers the risk of the most common causes?
Many of the leading causes share the same main risk factors. This is general public health information, not medical advice. Talk to a doctor about your own risks.
- Not smoking. Smoking raises the risk of heart disease, stroke, COPD and lung cancer. Quitting at any age helps. See smoking and life expectancy.
- Blood pressure. High blood pressure is a major cause of stroke and heart disease, and it often has no symptoms. A simple check is worth it.
- Weight and diabetes. A healthy BMI lowers the risk of diabetes, heart disease and some cancers. See what BMI means.
- Activity. Regular movement lowers heart and stroke risk.
- Alcohol. Less alcohol means lower risk of liver disease, several cancers and injuries.
- Road safety. Seat belts, helmets and not driving after drinking prevent many young deaths.
- Screening and vaccines. Many cancers and infections are far easier to treat or prevent when caught early.
You can see how several of these habits change your own estimate in the “What moves your estimate” panel of the death clock.
How am I going to die? Can a calculator tell me my cause of death?
No. A “cause of death calculator” that names one cause for you is guessing. Real causes depend on your health history, genes, environment and chance. What we show are population shares: out of all deaths in your group, how many came from each cause. That is useful for knowing which risks matter most at your age, and nothing more.
Frequently asked questions
How will I die?
No one can know how one person will die. What statistics show is the most common causes for people of your age, sex and country. For adults worldwide, heart disease and stroke lead, and many top causes are linked to smoking, weight, blood pressure and activity.
What will be my cause of death?
No test or calculator can name it. Tools that give one cause are guessing. The tool on this page shows the share of deaths from each leading cause in your group, from WHO data, which tells you which risks matter most at your age.
What is the most common cause of death?
Worldwide, ischaemic heart disease is the leading cause of death in adults, followed by stroke. In WHO’s 2021 estimates, COVID-19 was also near the top because of the pandemic.
What is the most common cause of death for young people?
For young men aged 15 to 29 worldwide, road injuries lead, followed by violence and self-harm. For young women, complications of pregnancy and childbirth lead worldwide, mostly in countries with weaker maternal care.
Can I find my death date and cause?
For “when”, our death clock gives an average age and range for people like you. For “how”, the tool on this page shows common causes for your group. Neither can predict your own future, but both show which habits matter.
