Global Life Expectancy and Average Age at Death
Global average life expectancy reached about 73.4 years in 2024, according to the World Health Organization, with women living longer than men on average. In high-income countries, life expectancy is above 80 years, while in parts of sub-Saharan Africa it remains below 65 years. These figures represent a partial recovery from the COVID-19 pandemic but still show a gap between developed and developing regions source: WHO.
The highest national life expectancy is found in Japan, Switzerland, and Singapore, where people routinely live past 85 years. The lowest is in countries affected by conflict, malaria, and weak health systems, where average death ages can fall below 55 years. These differences are driven by nutrition, sanitation, access to vaccines, and the prevalence of non-communicable diseases source: WHO GHO.
How People Die: Leading Causes by Age Group
For adults over 30, the main causes of death are ischemic heart disease, stroke, chronic obstructive pulmonary disease, and lower respiratory infections. Cancer moves up the list after age 50, with lung, colorectal, liver, stomach, and breast cancers accounting for millions of deaths each year. Road injuries, self-harm, and kidney disease also rank highly in global mortality statistics source: WHO.
Age-Specific Mortality Patterns
For children under 5, pneumonia, birth complications, and malaria are the top killers, while adolescents and young adults face higher risks from road injuries, violence, and suicide. In middle age, heart attacks and strokes become the dominant causes, and after 70, neurodegenerative diseases such as Alzheimer's and other dementias grow rapidly in frequency. The probability of dying from any cause increases sharply after age 65, doubling roughly every 8 years source: CDC.
Personal Risk Factors and How to Estimate Your Own Timeline
Individual life expectancy depends on genetics, sex, smoking status, alcohol use, body mass index, blood pressure, and access to healthcare. Tools such as the Framingham Risk Score and the CDC's Life Expectancy Calculator use these inputs to estimate the statistical chance of surviving to specific ages. People with diabetes, chronic kidney disease, or a history of cancer typically face a lower average age at death than the general population source: CDC.
Reducing Mortality Risk
Controlling blood pressure, avoiding tobacco, limiting alcohol, maintaining a healthy weight, and regular physical activity can add years to life. Early screening for cancers and cardiovascular disease shifts the age of diagnosis earlier and often prevents death at younger ages. Public health improvements such as clean water, vaccination programs, and anti-smoking policies have raised the global average age at death by more than 10 years since 1950 source: WHO GHO.
