Which Countries Have the Most People Aged 100 and Older in 2025
Japan Leads the World in Centenarian Population
Japan continues to hold the top spot globally for the highest number of citizens aged 100 and older, with approximately 123,300 individuals over the age of 100 in 2025. This remarkable longevity is often attributed to Japan’s advanced healthcare system, traditional diet rich in fish and vegetables, and high standard of living. The country has long been recognized for its high life expectancy, particularly among women, which contributes significantly to its large centenarian population. The aging trend underscores the importance of healthcare innovations and social support systems in Japan, setting a high standard for other nations aiming to improve longevity.
The United States Maintains its Position Amid Rising Numbers
The United States follows with roughly 73,600 individuals aged 100 and above. Due to diverse demographics, advanced medical care, and improved quality of life, the U.S. has seen a steady increase in its elderly population. States like Florida, California, and New York have particularly high numbers of centenarians, reflecting regional differences in healthcare access and lifestyle factors. The growing aging population challenges policymakers to develop sustainable healthcare, housing, and social programs tailored for the needs of the oldest Americans.
China’s Rapid Growth in the Centenarian Demographic
China reports approximately 48,500 centenarians in 2025, marking a dramatic rise driven by improvements in healthcare, nutrition, and living standards over recent decades. With China’s massive population, even a small percentage reaching age 100 translates into a significant number of elders. Urbanization and modernization have played roles in increasing longevity, although rural areas still face challenges related to healthcare access. As China’s elderly population grows, the nation faces the task of expanding elderly care infrastructure and social support services.
