The World Health Organization's global assessment for the 2000-2023 period found that average life expectancy reached 73.3 years in 2023. The global figure was thus just 0.1 years below its 2019 level, before the COVID-19 pandemic.
The assessment examined changes in life expectancy, causes of death and trends in the global burden of disease. The findings showed that the global health landscape is changing and that people continue to live longer.
Healthy years did not increase at the same pace
Expected healthy life expectancy was calculated at 62.8 years in 2023. This was 0.4 years below the 2019 level.

The share of noncommunicable diseases in total deaths rose from 58% in 2000 to 74% in 2023. Diabetes, dementia, mental disorders and disorders linked to psychoactive substance use played an increasingly significant role in the transformation of the global disease burden.
Low-income countries cross a critical threshold
The shift became evident in countries across all income groups. In low-income countries, 2023 was the first year in which infectious diseases accounted for less than half of all deaths.

Alain Labrique, Director of the World Health Organization's Department of Data, Digital Health, Analytics and Artificial Intelligence, described the rise in life expectancy as one of the greatest achievements in public health.
Labrique said the priority was to ensure that people remain healthy during their longer lives and to prepare health systems to respond to the changing needs of the population.
