Life contingencies
What is life table ? Life tables are used to describe age-specific mortality and survival rates for a population. A life table is a table which shows, for a person at each age, what the probability is that they die before their next birthday. From this starting point, a number of statistics can be derived and thus also included in the table is: the probability of surviving any particular year of age the remaining life expectancy for people at different ages the proportion of the original birth cohort still alive. What are the types of life-table ? 1. Cohort or age-specific or dynamic life tables: a cohort is a group of individuals all born during the same time interval. To prepare cohort specific life table, data are collected by following a cohort throughout its life. 2. Static or time-specific life tables: age-distribution data are collected from a cross-section of the population at one particular time or during a short segment of time, such as through mortality
