LIFE TABLE Meaning and
Definition
-
A life table is a statistical tool used in demography, actuarial science, and epidemiology to analyze mortality rates and other vital statistics in a population. It is a systematic and comprehensive compilation of data on the life expectancy and survival probabilities for individuals within a particular population.
Life tables typically present data in an age-specific format, organizing individuals into groups based on their age at a given time, often from birth to the highest age reached in the population. The table provides key information such as the number of individuals alive in each age group, the probability of dying at each age, and the average remaining years of life for those who have survived to a certain age.
Life tables are crucial for studying patterns of mortality and predicting life expectancies. By examining the mortality patterns and survival rates of a population, researchers can analyze factors such as age, sex, or socioeconomic status that may impact longevity. Additionally, life tables are invaluable tools for actuarial calculations, allowing insurers and pension plans to estimate the probability of death and design appropriate policies or pension schemes.
Overall, life tables serve as a comprehensive and indispensable tool for understanding and analyzing mortality rates, providing insights into the trends and behavior of populations, and informing various fields such as public health, social sciences, and insurance industries.
