Life expectancy

Why is this important for social statistics?

Life expectancy gives a summary measure of the death and survival rates of the population.

This indicator measures the average length of life remaining at different ages. It assumes people experience the age-specific death rates of a given period from the given age onwards.

These are period life expectancy measures. They are likely to underestimate the actual life expectancy of people, because death rates are likely to keep declining during people's lifetimes. For an indication of actual (cohort) life expectancy, see How long will I live?
