List of countries by life expectancy
| Life expectancy versus health expenditure |
This list of countries and territories by life expectancy provides a comprehensive list of countries alongside their respective life expectancy figures. The data are 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, 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 2022 report.
Methodology
The life expectancy is shown separately for males and for females, as well as a combined figure. Several non-sovereign entities and territories are also included in this list.The figures reflect the quality of healthcare in the countries listed, as well as other factors including HIV infections.
From the start of the 21st century, estimates of healthy life expectancy, the average number of years that a person can expect to live in "full health", are also produced.
Comparing life expectancies across countries can be difficult, due to poor reporting in some countries and different local standards in collecting statistics.
This is especially true for healthy life expectancy, the definition of which may change over time, even within a country. For example, Canada is a country with a fairly high overall life expectancy at 81.63 years. This number decreases to 75.5 years for Indigenous people in Canada. This discrepancy is echoed in most quality of life metrics across Canada.
United Nations (2023)
Estimations are by the United Nations Department of Economic and Social Affairs. Only countries with populations over 50,000 are listed. Due to this criterion, the table does not include such countries as Monaco, San Marino, and Saint Barthélemy. The values are rounded. All calculations were made with raw data.These values are used to calculate the Human Development Index.
World Bank Group (2023)
Estimation of the World Bank Group for 2023. Only countries with populations over 50,000 are listed. Due to this criterion, the table does not include such countries as Monaco, San Marino, and Liechtenstein. The values in the World Bank Group tables are rounded. All calculations were done on raw data, therefore, due to the nuances of rounding, in some places illusory inconsistencies of indicators arose, with a size of 0.01 year.In 2014, some of the world's leading countries had a local peak in life expectancy, so this year is chosen for comparison with 2019 and 2023.
