Global human life expectancy reached 73.3 years in 2023, nearly recovering its pre-pandemic peak of 73.4 years recorded in 2019, according to estimates published by the World Health Organization (WHO) and reported by fr.allafrica.com. This rebound erases a drop of nearly two years observed between 2019 and 2021, though recovery speeds vary significantly across different regions of the world.
Global Life Expectancy Rebounds Toward Pre-Pandemic Levels
The new WHO data shows that average global life expectancy at birth has bounced back from the disruptions caused by the COVID-19 pandemic. The figures indicate that the global population has largely regained the longevity gains lost during the height of the global health crisis.
However, healthy life expectancy—the number of years lived in full health—is recovering at a slower pace. Healthy life expectancy reached 62.8 years in 2023, which leaves a lingering deficit of 0.4 years compared to the 2019 baseline of 63.2 years. The WHO identifies maintaining overall health during these gained years as a primary public health challenge moving forward.
Non-Communicable Diseases Drive Shift in Global Mortality
The underlying causes of death have undergone a profound transformation over the past two decades. Non-communicable diseases accounted for 74 percent of all global deaths in 2023, a significant increase from 58 percent in the year 2000. These conditions now occupy eight of the top ten leading causes of death worldwide.
Cardiovascular diseases remain the leading cause of mortality globally. Ischemic heart disease alone caused approximately 9.5 million deaths in 2023, resulting in the loss of roughly 210 million healthy life years.
Other non-communicable conditions are also claiming a growing share of global mortality and morbidity. Diabetes, cancers, chronic respiratory diseases, and neurodegenerative conditions show rising impacts across global populations.
Alzheimer’s disease and other forms of dementia experienced a dramatic rise, moving from the 19th leading cause of death in 2000 to the 5th leading cause in 2023. Over that period, the total number of deaths attributed to these conditions tripled.
Mental Health Disorders Show Marked Post-Pandemic Increases
Mental health burdens have also intensified over the reporting period. The global rate of healthy life years lost, adjusted for age, climbed by approximately 20 percent for depressive disorders between 2019 and 2023. During the same timeframe, the rate for anxiety disorders surged by nearly 45 percent globally.
