Human life expectancy is a statistical measure of the estimate of the average remaining years of life at a given age. The most commonly used measure is life expectancy at birth (LEB, or in demographic notation e0, where ex denotes the average life remaining at age x ). This can be defined in two ways.
On this page, you will find global data and research on life expectancy and related measures of longevity: the probability of death at a given age, the sex gap in life expectancy, lifespan inequality within countries, and more. Life expectancy has increased across the world.

The term lifespan is most commonly confused with another important concept: life expectancy. While both terms relate to the number of living years, they actually define very different concepts. While the term lifespan refers to the maximum number of years an individual can live, life expectancy refers to an estimate or an average number of years a ...
Given that the human lifespan is defined by the longest observed human life from birth to death, it is a figure that has changed over the years. For humans, the current accepted maximum lifespan is 122 years. This age was achieved by Jeane Louise Calment of France. Calment lived from February 21, 1875, to August 4, 1997, until she was exactly 122 y...
With the United State's average life expectancy currently hovering at around 79 years, the age to which most Americans can expect to live is still forty-four years younger than the human lifespan. So how do we close that gap and elongate our lives? There will always be factors that are out of our individual control like our inherited genes, but ...
