Death Rate by Age Group — At What Age Are You Most Likely to Die?
Your risk of dying changes dramatically as you age — and what kills you changes too. Here is the full breakdown by decade, from infancy to old age.
Here is something most people never think about: the thing most likely to kill you right now is probably not the same thing that will kill you in twenty years. At fifteen, your biggest risk is a car crash. At forty-five, it is a heart attack. At seventy-five, it is a stroke or dementia. Your relationship with death changes as you age — the danger shifts underneath you without you ever noticing.
So I pulled the data and laid it all out. This is what kills people at every stage of life.
The overall pattern
Let me start with the big picture. Here is how the annual death rate changes across age groups globally.
| Age group | Death rate per 100,000 | How many die per year | Primary risk |
|---|---|---|---|
| Under 1 | 3,800 | 3,900,000 | Neonatal conditions |
| 1–4 | 90 | 1,100,000 | Infection & malnutrition |
| 5–14 | 17 | 350,000 | Accidents |
| 15–24 | 85 | 1,050,000 | Road injuries & violence |
| 25–34 | 100 | 1,200,000 | Road injuries & self-harm |
| 35–44 | 160 | 1,700,000 | Heart disease emerging |
| 45–54 | 340 | 3,100,000 | Heart disease & cancer |
| 55–64 | 720 | 5,400,000 | Cancer & heart disease |
| 65–74 | 1,550 | 8,200,000 | Heart disease & cancer |
| 75–84 | 3,800 | 12,500,000 | Heart & respiratory |
| 85+ | 12,000 | 10,500,000 | Heart, dementia, respiratory |
The pattern is a U-shape — or more accurately, a swooping curve. Death rates are high in infancy, drop to their lowest point between ages 5 and 14, then rise steadily from the mid-twenties onward, accelerating sharply after 65.
The safest decade of your life, statistically, is your second one. A child between 5 and 14 has a death rate of just 17 per 100,000 — roughly 1 in 6,000 per year. By age 85, that same rate has climbed to 12,000 per 100,000, or roughly 1 in 8. Your risk of dying in any given year increases by a factor of about 700 between childhood and old age.
You can see how your own country's life expectancy compares on our life expectancy table.
The first year: the most dangerous
This might surprise you. The most dangerous single year of your life — the one with the highest probability of death — is your first.
| Neonatal cause | Deaths in first year | Share |
|---|---|---|
| Preterm birth complications | 800,000 | 21% |
| Birth asphyxia and trauma | 580,000 | 15% |
| Neonatal sepsis (infections) | 500,000 | 13% |
| Congenital abnormalities | 280,000 | 7% |
| Pneumonia | 350,000 | 9% |
| Diarrhoea | 250,000 | 6% |
| Other | 1,140,000 | 29% |
A death rate of 3,800 per 100,000 means roughly 1 in every 26 babies born worldwide will not survive to their first birthday. In high-income countries, that number drops to about 1 in 250. In the poorest countries, it can be as high as 1 in 10.
The first 28 days — the neonatal period — is when the majority of infant deaths occur. After that, the risk drops rapidly. By six months old, a baby is dramatically safer than it was at birth.
We cover this in much more detail in our article on how many children die every day.
Ages 5–14: the golden decade
Between 5 and 14, death rates hit their global minimum. Children in this age range have generally survived the infectious disease gauntlet of early childhood, they are not yet driving, and the chronic diseases of adulthood have not started.
| Cause of death (ages 5-14) | Annual deaths | Share |
|---|---|---|
| Road traffic injuries | 55,000 | 16% |
| Drowning | 50,000 | 14% |
| Lower respiratory infections | 40,000 | 11% |
| Malaria | 30,000 | 9% |
| Cancer (leukaemia, brain tumours) | 25,000 | 7% |
| Diarrhoeal diseases | 20,000 | 6% |
| Violence and conflict | 18,000 | 5% |
| Other | 112,000 | 32% |
Drowning is one of the leading killers in this age group — a fact that gets very little attention. Fifty thousand children between 5 and 14 drown every year, mostly in low- and middle-income countries where swimming lessons are uncommon and open water is unguarded.
Ages 15–29: when external causes dominate
The teenage and young adult years are when the cause-of-death profile shifts dramatically. Internal, biological causes give way to external, behavioural ones.
| Cause of death (ages 15-29) | Annual deaths | Share |
|---|---|---|
| Road traffic injuries | 390,000 | 22% |
| Suicide | 200,000 | 11% |
| Interpersonal violence | 180,000 | 10% |
| Tuberculosis | 120,000 | 7% |
| HIV/AIDS | 100,000 | 6% |
| Drowning | 90,000 | 5% |
| Maternal conditions | 70,000 | 4% |
| Cancer | 65,000 | 4% |
| Other | 535,000 | 31% |
Road injuries are the number one killer of people aged 15 to 29. Not disease. Not genetics. Cars. This is the age where people start driving, start taking risks, and start dying for it. Young men are particularly affected — they account for roughly 75% of road deaths in this age bracket.
Suicide is the second leading cause — 700,000 people per year across all ages, with a disproportionate share among young adults. It is the leading cause of death for 15-29 year olds in some high-income countries, including the UK for young men.
Violence is third. In some countries — particularly in Central America, southern Africa, and parts of South Asia — interpersonal violence is the leading cause of death for young men, outstripping even road injuries.
Ages 30–49: the transition zone
This is the decade where lifestyle catches up with biology. The risky behaviours of youth either moderate or start extracting a toll, and the chronic diseases of middle age begin to appear.
| Cause of death (ages 30-49) | Annual deaths | Share |
|---|---|---|
| Cardiovascular disease | 1,100,000 | 23% |
| Cancer | 800,000 | 17% |
| HIV/AIDS | 400,000 | 8% |
| Road traffic injuries | 350,000 | 7% |
| Liver disease (alcohol, hepatitis) | 320,000 | 7% |
| Tuberculosis | 280,000 | 6% |
| Suicide | 250,000 | 5% |
| Diabetes | 200,000 | 4% |
| Other | 1,100,000 | 23% |
Heart disease appears as the number one killer for the first time. By age 35, cardiovascular disease begins its long ascent to dominance. The first heart attacks in seemingly healthy people typically occur in the mid-forties — often in men who assumed they were fine because they felt fine.
Cancer also enters the picture significantly. Among women in this age group, breast cancer and cervical cancer are the dominant types. Among men, it is lung cancer (strongly linked to smoking) and colorectal cancer.
Liver disease makes its first significant appearance here — driven largely by alcohol and, increasingly, by non-alcoholic fatty liver disease from obesity. If you are in your thirties or forties and drink regularly, the liver warning signs article is worth reading.
Ages 50–69: the chronic disease surge
By fifty, biological causes dominate completely. External causes like accidents and violence shrink to a small percentage, and the body's accumulated damage takes over.
| Cause of death (ages 50-69) | Annual deaths | Share |
|---|---|---|
| Cardiovascular disease | 5,200,000 | 33% |
| Cancer (all types) | 4,100,000 | 26% |
| Chronic respiratory disease | 1,100,000 | 7% |
| Diabetes | 900,000 | 6% |
| Liver disease | 650,000 | 4% |
| Kidney disease | 500,000 | 3% |
| Tuberculosis | 350,000 | 2% |
| Other | 2,800,000 | 18% |
Heart disease and cancer together account for nearly 60% of all deaths in this age group. This is the peak decade for cancer mortality — while heart disease keeps rising into old age, many cancers hit hardest in the fifties and sixties.
Chronic respiratory disease — primarily COPD — emerges as a major killer here, almost exclusively in smokers and ex-smokers. If you smoked for 20 years, this is the decade where the bill comes due.
Ages 70+: the final act
After 70, the pattern narrows to a handful of dominant causes. The body's systems fail in predictable ways, and the question is not whether chronic disease will kill you but which one.
| Cause of death (ages 70+) | Annual deaths | Share |
|---|---|---|
| Cardiovascular disease | 11,100,000 | 38% |
| Cancer | 4,300,000 | 15% |
| Chronic respiratory disease | 2,200,000 | 8% |
| Dementia & Alzheimer's | 1,800,000 | 6% |
| Diabetes | 1,400,000 | 5% |
| Lower respiratory infections | 1,300,000 | 4% |
| Kidney disease | 900,000 | 3% |
| Falls | 400,000 | 1% |
| Other | 5,600,000 | 19% |
Dementia becomes a major killer for the first time, accounting for 6% of deaths in over-70s. Among women over 80, it is often the leading cause. The numbers here are probably understated — dementia is frequently listed as a contributing factor rather than the primary cause of death on death certificates.
Falls also appear on the list. Four hundred thousand people over 70 die from falls each year. A hip fracture in an 85-year-old is not just a broken bone — it is often the beginning of a rapid decline that ends in death within months.

What this means for you
The practical takeaway from all this data is simple: the things that will kill you change over time, so the things you should worry about should change too.
- In your teens and twenties — wear your seatbelt, do not drive drunk, look after your mental health. Heart disease is not your problem yet. Cars and self-harm are.
- In your thirties and forties — get your blood pressure and cholesterol checked. Start exercising if you do not already. Cut back on alcohol. The foundations of your fifties are being laid right now.
- In your fifties and sixties — get cancer screenings (colonoscopy, mammograms, lung CT if you smoked). Manage your cardiovascular risk factors aggressively. This is the decade where prevention becomes urgent.
- In your seventies and beyond — stay physically active (even walking counts). Stay socially engaged (isolation is a dementia risk factor). Prevent falls (strength training, balance exercises, removing trip hazards at home).
The data does not care about your age. It just tells you what kills people like you. What you do with that information is up to you.
While you have been reading this — about 11 minutes — roughly 1,290 people have died worldwide. Their ages spanned from newborn to centenarian, and what killed each of them was shaped by where they fell on the curve.
