Concept information
Preferred term
average life expectancy
Definition
- Life expectancy is the average number of years remaining to an individual of a specified age if the mortality conditions implied by a particular period (cross-sectional) or cohort (longitudinal) life table applied; the former projects the years remaining to all people of a given age, and the latter projects years remaining to all people born in a given year. Life expectancy is widely used as an indicator of mortality conditions because it is based on the mortality experience at all ages and is independent of age structure.
