 List of countries by life expectancy

As of my last update in October 2023, life expectancy data can vary somewhat based on the source and the year of the report. Generally, the World Health Organization (WHO), the United Nations (UN), and the World Bank are reliable sources for this information. Typically, countries with the highest life expectancy often include: 1. **Japan** 2. **Switzerland** 3. **Singapore** 4. **Spain** 5. **Italy** 6. **Australia** 7.
