While global life expectancy is on the rise, disparities between countries remain significant. The advantages enjoyed by long-lived nations in healthcare and living conditions stand in stark contrast to the limitations faced by under-resourced regions, highlighting persistent global health inequalities.

TAIPEI, TAIWAN (MERXWIRE) – According to World Health Statistics 2025, global life expectancy has gradually rebounded after the pandemic shock, returning to around 73–74 years. However, between 2019 and 2021, global life expectancy declined by 1.8 years, marking a significant reversal of more than a decade of progress. As a result, 2025 is viewed as a critical turning point for recovery and rebuilding in global health systems.

As healthcare systems gradually resume normal operations worldwide, global life expectancy is trending upward again. However, structural disparities persist. Data from Worldometer shows that life expectancy remains concentrated, with long-lived countries primarily clustered in European microstates, East Asia, and developed economies.

According to Worldometer, Monaco ranks highest in global life expectancy in 2026 at 86.73 years, followed by San Marino (86.03), Hong Kong (85.9), Japan (85.15), and South Korea (84.64). The top ten also include Saint Barthélemy, Andorra, French Polynesia, Switzerland, and Australia, all with life expectancy exceeding 84 years, underscoring the importance of high income levels and well-developed healthcare systems in extending lifespan.

2026 Countries ranked by life expectancy

Monaco has long held the top position in global longevity, largely benefiting from a low-stress lifestyle, a Mediterranean diet, and high-quality public healthcare, all contributing to stable population health. Japan, widely recognized as one of the world’s leading longevity nations, reports an average life expectancy of 88.18 years for women and 82.13 years for men. Key factors include a diet rich in fish, vegetables, and fermented foods, low obesity rates, and a culture of highly regular daily routines.

South Korea and Hong Kong also rank among the top globally, reflecting East Asia’s long-term investment in healthcare accessibility and public health policies. Singapore, with a life expectancy of 84.13 years, further demonstrates that highly urbanized nations can achieve longevity with efficient healthcare systems and quality living conditions. Taiwan, with an average life expectancy of 81.14 years, ranks 51st globally—slightly below the top tier but still within a high global standard.

A closer look at the full Worldometer rankings reveals that some countries remain in the lower life expectancy range. For instance, Nigeria (54.95 years), the Central African Republic (58.15), Chad (55.58), and South Sudan (57.97) lag significantly behind. Compared to high-longevity nations like Monaco and Japan, the gap can exceed 30 years, highlighting stark global health inequalities.

From a broader perspective, disparities in economic development—both between countries and within populations—are directly reflected in life expectancy outcomes. Studies show that low income and high inequality can significantly shorten lifespan. Among those aged 60 and above, lower-income individuals may live about nine years less than their wealthier counterparts. In the United States, men in the top 1% income bracket can live approximately 15 years longer than those in the bottom 1%, demonstrating how longevity is influenced by wealth, education, and lifestyle.

Although global life expectancy is gradually recovering after the pandemic, disparities between countries remain evident. Long-lived nations typically benefit from stable healthcare systems, comprehensive public health policies, and healthy lifestyles. In contrast, countries with shorter life expectancy continue to face challenges such as limited medical resources and inadequate infrastructure. Strengthening international public health cooperation to improve healthcare conditions in these regions will be crucial in narrowing the global life expectancy gap.
