2-remaining life expectancy for people at different ages 3-the proportion of the original birth cohort still alive 4-estimates of a cohort's longevity characteristics. The table is actually a snapshot in of the present time. The prediction of life expectancy, Item 1 & 2, is predicated on conditions surrounding mortality remaining the same.
