longevity Meaning and Definition
1. n. the property of being long-lived
2. n. duration of service
The word "longevity" is sometimes used as a synonym for "life expectancy" in demography - however, the term "longevity" is sometimes meant to refer only to especially long-lived members of a population, whereas "life expectancy" is always defined statistically as the average number of years remaining at a given age.
