At a Glance
- Global life expectancy reached 73.3 years in 2023, close to the 2019 level of 73.4 years.
- Healthy life expectancy recovered more slowly to 62.8 years, still 0.4 years below 2019.
- Noncommunicable diseases (NCDs) caused 74% of global deaths in 2023, up from 58% in 2000.
- Eight of the ten leading global causes of death in 2023 were NCDs.
- WHO highlights cardiovascular disease, diabetes, dementia, mental health conditions and drug-use disorders as major parts of the changing disease burden.
What has WHO reported?
The World Health Organization has released its latest Global Health Estimates, describing changes in mortality, life expectancy and disease burden across countries and regions between 2000 and 2023. The figures show that the world has largely recovered the pandemic-era loss in overall life expectancy, but the number of years lived in good health has not recovered at the same pace.
WHO estimates global life expectancy at 73.3 years in 2023, compared with 73.4 years in 2019. Healthy life expectancy was 62.8 years in 2023, remaining below the pre-pandemic level.
NCDs continue to dominate global mortality
The most important long-term trend is the continuing shift toward noncommunicable diseases. NCDs accounted for 74% of all deaths globally in 2023, compared with 58% in 2000. WHO also reports that eight of the ten leading causes of death were noncommunicable diseases.
Cardiovascular disease remains the leading cause of death and disease burden. Ischaemic heart disease alone was associated with about 9.5 million deaths and roughly 210 million disability-adjusted life years (DALYs) in 2023.
Diabetes and dementia are increasingly important
WHO notes that the risk of dying from diabetes has increased substantially since 2000, with a particularly important rise in South-East Asia. Dementia has also moved rapidly up the global ranking: Alzheimer disease and other dementias became the fifth leading cause of death globally in 2023, compared with 19th in 2000. WHO estimates that global deaths from dementia tripled over this period.
Mental health burden has also risen
Between 2019 and 2023, WHO estimates that the global age-standardized DALY rate rose by approximately 20% for depressive disorders and nearly 45% for anxiety disorders. Together, these conditions accounted for an estimated 110 million years of healthy life lost through disability and premature death in 2023.
Why this matters for India
For India and other countries in the WHO South-East Asia Region, the report reinforces the need to manage a dual burden: infectious diseases remain relevant, while cardiovascular disease, diabetes, cancer, chronic respiratory disease and mental-health conditions require stronger long-term prevention, screening and treatment systems.
The WHO estimates are population-level evidence and should not be interpreted as an individual risk prediction. National and state-level planning should also use India-specific surveillance, registration and programme data.
Key takeaway for clinicians and health planners
Longer life expectancy is a major public-health achievement, but the policy challenge is increasingly about extending healthy life expectancy. Prevention of cardiovascular and metabolic disease, earlier detection, continuity of chronic-care services and stronger mental-health systems are likely to become even more important.
