This list of countries by life expectancyprovides a comprehensive list of countries alongside their respective life expectancyfigures. The data is differentiated by sex, presenting life expectancies for males, females, and a combined average. In addition to sovereign nations, the list encompasses several non-sovereign entities and territories. The figures serve as an indicator of the quality of healthcare in the respective countries and are influenced by various factors, including the prevalence of diseases such as HIV/AIDS. This article introduces the concept of Healthy life expectancy (HALE), which denotes the average number of years a person is expected to live in "full health". There are challenges in comparing life expectancies across countries due to disparities in data reporting and collection standards. The primary source of the most recent data presented is the World Bank Group's 2021 report.
