life table calculations

Life table calculations are a way to analyze the survival and mortality patterns of a population. They track a group of people (or animals) year by year, estimating how many survive, die, or reach each age. From this, we can determine probabilities of dying at specific ages, average remaining lifespans, and overall mortality trends. These calculations help public health officials, insurers, and researchers understand longevity, plan resources, and assess risks. Essentially, a life table provides a statistical snapshot of how a group’s survival chances change over time.
