Top countries for longest life expectancy in 2025
Recent data confirms that several countries and territories consistently demonstrate remarkable longevity. While rankings can vary slightly between different reports, some key players consistently feature at the top. These nations often combine high-quality healthcare systems with prosperous, stable living conditions. According to a mid-2025 report from Visual Capitalist, Monaco, a glamorous Mediterranean microstate, holds the top spot with an average life expectancy of 87 years.
Other contenders for the highest life expectancy
Beyond Monaco, other nations and territories also boast impressive figures. Hong Kong and San Marino frequently contend for the top positions, reflecting their excellent standards of living. East Asian nations like Japan and South Korea also consistently rank highly, showcasing the benefits of healthy diets and proactive public health strategies. Switzerland and Australia are also often cited for their strong healthcare infrastructure and high quality of life.

- San Marino: This small republic is close behind with 85.8 years, offering a high standard of living and effective healthcare.
- Hong Kong: Known for its dense population and efficient government-operated hospitals, Hong Kong's life expectancy is 85.6 years.
- Japan: The Japanese diet and strong national medical insurance contribute to a life expectancy of 84.8 years.
- South Korea: Rapid public health advancements have propelled South Korea's life expectancy to 84.4 years.
- Switzerland: Excellent healthcare coverage, with 99.5% of citizens insured, helps ensure a life expectancy of 84.1 years.
- Australia: The only non-European or Asian country in some top-10 lists, with a life expectancy of 84.1 years.
- Singapore: Proactive public health policies and an advanced medical system contribute to an average lifespan of 83.9 years.
Key factors that influence longevity
While genetics play a minor role, numerous societal and individual factors are far more influential in determining life expectancy. A strong economy and robust healthcare system are often a country's most significant assets for promoting longevity.
Economic and social stability
Wealthier nations can invest more in essential public services like education, sanitation, and social safety nets, which all contribute to better health outcomes. Political stability also provides a foundation for long-term health improvements, as opposed to regions affected by conflict, which see dramatic reductions in life expectancy. In countries with lower income inequality, health outcomes may also be more evenly distributed across the population.
Healthcare access and quality
High-quality and universally accessible healthcare is a consistent theme among nations with the highest life expectancies. Universal coverage ensures that preventative care, vaccines, and treatments for chronic and infectious diseases are available to more of the population, including vulnerable groups. In contrast, countries with limited access to healthcare struggle with higher rates of preventable illnesses and mortality. The United States, for example, spends more per capita on healthcare than many peer countries but has a lower life expectancy, partly due to factors like access issues, high infant mortality, and lifestyle choices.
Diet, lifestyle, and environment
Diet and lifestyle habits are also crucial. The Japanese diet, rich in fish and vegetables and low in fat, is often cited as a contributing factor to their longevity. Similarly, the Mediterranean diet is celebrated for its cardiovascular benefits. Additionally, cultural factors like strong social ties and a sense of community can help mitigate stress and improve mental well-being, which has a positive impact on physical health. A clean environment with access to safe water and air is also critical.
Comparison of longevity factors: Monaco vs. a low-longevity country
| Feature | Monaco (High Life Expectancy) | Chad (Low Life Expectancy) |
|---|---|---|
| Economic Status | Extremely high GDP per capita, wealthy population. | Low GDP per capita, high poverty rates. |
| Healthcare System | World-class, high-spending, advanced medical technology. | Inadequate health services, limited access to care. |
| Diet and Nutrition | Access to high-quality, varied food. Balanced diets. | Food insecurity, high rates of malnutrition. |
| Political Stability | Highly stable and peaceful. | Conflict-affected, politically unstable. |
| Environmental Factors | Clean environment, advanced sanitation. | Poor sanitation, limited access to clean water. |
| Disease Burden | Low rates of infectious and chronic diseases. | High rates of infectious diseases like HIV/AIDS. |
| Social Support | Strong community and social support networks. | Social services are often disrupted or absent. |
Conclusion
While no single factor determines a nation's life expectancy, a combination of societal and personal elements heavily influences it. High-income countries with excellent healthcare access, social stability, and healthy lifestyles tend to have the longest average lifespans, with microstates like Monaco often topping the charts due to their unique demographics and resources. Conversely, nations grappling with poverty, political instability, and disease face severe challenges in improving their population's longevity. This disparity underscores the importance of equitable access to health resources, education, and social support in fostering a healthier, longer-living global population.
