Life expectancy is the expected number of years of life remaining at a given age. In common language, it is the average number of years one can continue to live for at a given age. For example, life expectancy at birth for the United Kingdom baby boy population was 79.2 years in 2014-2016 (the latest data). It means that, assuming the life style and medical technology etc. do not change in the future, babies born in 2014-2016 will on average die at 79.2 years old.
The calculation is based on the latest United Kingdom mortality data (2014-2016 data). The calculated life expectancy is not accurate if you live outside of UK, but you can use it as reference.
