Abstract

Program LIFE performs a life table analysis. The life table model may either be current or cohort, and either of these may be unabridged or abridged. For a current life table, input data consists of number of individuals and deaths in each age class obtained over a short period of time relative to the mortality rate. For a cohort life table, the data are obtained over the life span of the cohort. When the basic time unit is taken in equal increments, the life table is termed unabridged; otherwise, the life table is termed abridged.
