Longevity index
\lɔnˈʤɛvəti\ \ˈɪndɛks\
A standardized measure used to track the survivorship and life expectancy of a specific population over time.
Published longevity indices can be used to set standard terms for traded longevity instruments such as longevity bonds, longevity swaps, and longevity swaptions, reducing the level of complexity and increasing the level of liquidity in such trades.
