Global life expectancy reaches 73.3 years as WHO tracks post-pandemic recovery

Post-pandemic life expectancy trends

Global life expectancy reached 73.3 years in 2023, recovering from a drop to 71.5 years in 2021 during the Covid-19 pandemic. The figure approaches the pre-pandemic benchmark of 73.4 years recorded in 2019, according to the annual World Health Statistics report and Global Health Estimates released by the World Health Organization on 2 October 2026. The data tracks changes in mortality, morbidity, and disease burden across countries and regions between 2000 and 2023.

While overall lifespan has nearly recovered to pre-pandemic levels, the number of years lived in good health has rebounded at a slower pace. Global healthy life expectancy stood at 62.8 years in 2023, which is 0.4 years lower than the level registered in 2019. The resulting gap means that people live an average of more than ten years with health impairments. Alain Labrique, director of the Department of Data, Digital Health, Analytics and AI at the WHO, noted the milestone in a public statement.

Living longer is one of the great achievements of public health.

The rising burden of chronic illnesses

Non-communicable diseases accounted for 74% of all deaths worldwide in 2023, a substantial rise from the 58% recorded in 2000. These chronic conditions comprised 8 of the 10 leading causes of death globally. Across all causes, the top 10 conditions accounted for 33 million of the 61 million total deaths recorded worldwide in 2023.

Mortality concentrated primarily in two health domains: cardiovascular diseases and respiratory conditions. Cardiovascular illnesses, including ischaemic heart disease and stroke, remained the leading causes of death and overall disease burden globally. Respiratory conditions, such as chronic obstructive pulmonary disease and lower respiratory infections, also ranked among the primary contributors. In addition, global deaths from dementia tripled between 2000 and 2023, while health losses associated with depression and anxiety increased steeply in the years following the pandemic. Alain Labrique outlined the next priorities for healthcare systems.

The next challenge is to ensure that these additional years are lived in good health, while adapting health systems to meet the changing needs of populations.

Regional disparities and the epidemiological transition

The WHO estimates detailed marked differences in health outcomes across world regions between 2000 and 2023. The region of the Americas recorded the largest increases in mortality risk and the steepest loss of years lived in good health over the 23-year evaluation period. In contrast, the Western Pacific region recorded a considerable decrease in both mortality risk and the loss of healthy life years.

The report also documented an epidemiological shift within developing economies. In 2023, communicable diseases accounted for less than half of all deaths in low-income countries for the first time on record. This development represents a transition where chronic non-communicable illnesses, including diabetes, Alzheimer's disease, and cardiovascular conditions, increasingly outpace infectious diseases even in regions where infections previously dominated mortality profiles.
