Actuarial table

Actuarial table, also known as a life table or mortality table, is a mathematical tool used by actuaries to assess the probability of a person's survival year-by-year for any given age, based on a multitude of factors. These tables are fundamental to the fields of insurance, pensions, and retirement planning.

Overview

An actuarial table presents the probability that a person of a specific age will die before their next birthday. These tables are constructed based on a large number of observations or data and are used to predict the likelihood of survival for different ages. The tables are typically constructed separately for men and women due to their different mortality rates.

Construction of Actuarial Tables

The construction of an actuarial table involves the collection and analysis of a large amount of data. The data is typically collected from a population over a specific period of time, and the mortality rates are calculated for each age group. The data is then adjusted for various factors such as smoking, alcohol consumption, and obesity.

Uses of Actuarial Tables

Actuarial tables are used in a variety of fields, including insurance, pensions, and retirement planning. In insurance, they are used to determine the premiums for life insurance policies. In pensions, they are used to calculate the amount of pension that a person is entitled to receive. In retirement planning, they are used to estimate the amount of money that a person needs to save for retirement.

Limitations of Actuarial Tables

While actuarial tables are a valuable tool, they do have some limitations. They are based on historical data, and therefore may not accurately predict future trends. They also do not take into account individual health conditions or lifestyle choices, which can significantly affect a person's life expectancy.
