Global life expectancy bounces back to near pre-pandemic levels, WHO says
Global Longevity Nears Its Pre-Pandemic Mark
Qinilo.com – Global life expectancy has climbed back to almost the level seen before COVID-19 disrupted health systems and communities worldwide. New World Health Organization estimates place average life expectancy at birth at 73.3 years in 2023, only 0.1 years below the 73.4-year figure recorded in 2019.
The recovery signals a major reversal after the pandemic caused a sharp setback in survival gains. Yet the wider health picture remains more complicated: people are living longer, but the number of years spent in good health has not recovered at the same pace.
“Living longer is one of the great achievements of public health,” said Dr. Alain Labrique, Director of WHO’s Department of Data, Digital Health, Analytics and AI.
WHO’s Global Health Estimates track deaths and disability across countries and regions from 2000 through 2023. They combine national vital-registration records with estimates developed through WHO technical programmes and partner organizations in the UN system. The figures help show not only how long people live, but also which illnesses and injuries are shaping health outcomes.
Healthy Years Still Lag Behind
Healthy life expectancy reached 62.8 years in 2023. That measure reflects the expected years a person can live in good health, rather than simply total years of life. Although it has improved since the worst of the pandemic period, it remained 0.4 years below the 2019 level.
The gap matters for families, health services and public budgets. A longer life can be a positive outcome of better prevention and treatment, but it also increases the importance of helping people remain mobile, independent and supported as they age. Health systems will need to respond to chronic conditions, disability and mental-health needs alongside acute illness.
“The next challenge is to ensure that those additional years are lived in good health, while health systems are equipped to respond to the changing needs of populations,” Dr. Labrique said.
A Changing Pattern of Illness and Death
The estimates show a continuing long-term change in the causes of death. In 2023, communicable diseases represented less than half of all deaths in low-income countries for the first time. These illnesses can pass between people, from animals to people, or from contaminated surfaces to people.
That milestone forms part of what WHO describes as the global epidemiological transition: as populations change and health conditions evolve, noncommunicable diseases take a larger share of illness and mortality. Progress against infections remains essential, particularly where health resources are limited, but chronic disease is now central to the global health agenda.
Noncommunicable diseases accounted for 74 per cent of deaths worldwide in 2023, rising from 58 per cent in 2000. Eight of the 10 leading causes of death globally were noncommunicable diseases. The category includes conditions such as heart disease, diabetes, dementia and many other illnesses that are not spread through infection.
Heart Disease Remains the Largest Burden
Cardiovascular disease continued to lead the world in both deaths and overall disease burden. Ischaemic heart disease alone was linked to roughly 9.5 million deaths in 2023 and to the loss of 210 million years of healthy life.
Many areas have achieved substantial reductions in this burden since 2000. However, risk rose for individuals in the Western Pacific and Southeast Asia regions, underlining the uneven nature of health progress. A global average can conceal major differences in access to prevention, diagnosis and ongoing care.
Other chronic conditions have moved rapidly up the rankings. Dementia rose from the world’s 19th-leading cause of death in 2000 to fifth place in 2023. Deaths associated with dementia tripled over that period. Diabetes has also become more dangerous, with the risk of dying from it increasing substantially since 2000, especially in South-East Asia.
Mental Health and Drug Use Demand Attention
The burden linked to mental-health conditions also increased in the years surrounding the pandemic. From 2019 to 2023, the global age-standardised rate of healthy life lost rose by roughly 20 per cent for depressive disorders. For anxiety disorders, the increase was close to 45 per cent.
These indicators capture more than mortality. They reflect years affected by reduced health, functioning and wellbeing, making them important for planning services that may not be visible in death statistics alone. The rise highlights why mental health support must be considered part of broader health-system resilience.
Drug use disorders showed a markedly different regional pattern. The Americas experienced the biggest increases in risk of death and healthy life lost between 2000 and 2023. The Western Pacific, meanwhile, registered substantial declines over the same period.
For policymakers, the value of these findings lies in their ability to identify where needs are growing and where progress has been made. Population health is changing in ways that require prevention, treatment and long-term care to work together rather than compete for attention.
“The value of these estimates is not only in the numbers themselves,” Dr. Labrique said. “By showing how causes of death and disease burden are changing over time and across populations, they give countries evidence to help shape health policies and priorities.”
The near-restoration of global life expectancy is an encouraging sign, but it is not an endpoint. The next measure of success will be whether people can gain not only additional years of life, but additional years lived in health.
