Abstract
BACKGROUND: The age distribution and remaining lifespan distribution are identical in stationary populations. The life table survival function is proportional to the age distribution in stationary populations. OBJECTIVE: We provide an alternative interpretation of the life table when viewed by remaining years of life. CONCLUSIONS: The functions describing the mortality of birth cohorts over age are identical to the functions describing the growth of death cohorts as time to death decreases in stationary populations.
