Life expectancy

Life expectancy is the measure of how long a person is expected to live. Life expectancy varies worldwide and involves many factors such as diet, gender, and environment. As medical care has improved over the years, life expectancy has increased worldwide. Introduction to medical care such as vaccines has significantly improved the lives of millions of people worldwide. The average worldwide life expectancy at birth has steadily increased since 2007.

Life expectancy worldwide

More developed countries tend to have higher life expectancies, for a multitude of reasons. Africa was the continent that had the lowest life expectancy for both men and women in 2019, while North America had the highest for men and Europe had the highest for females. The life expectancy of men at birth in the United States has slightly increased from 2007 to 2017. Additionally, women in the United States have also faced a slight increase in life expectancy over the same time period.
