Ranking criteria for the top 10 countries with the highest life expectancy

Life expectancy at birth is one of the most important measures of a country’s overall health and wellbeing. It is defined as the number of years a newborn infant could expect to live if prevailing patterns of age-specific mortality rates at the time of birth stay the same throughout the infant’s life. It is an indicator of the average lifespan of a person born in a particular country, and it is closely linked to a country’s overall health status, including factors such as access to healthcare, sanitation, and education. The United Nations’ Human Development Index (HDI) is a widely used tool for measuring the overall development of a country, which takes into account several factors, including life expectancy at birth. In this article, we have followed Human Development Index’s latest life expectancy at birth index ( data updates as of September 8th, 2022).
