Definition
Expectation of Life: In life insurance, this term refers to the estimated number of years remaining in the life of an average person of a certain age. This estimation is derived from statistical and actuarial data, often represented by a mortality or life table, providing a detailed probability of dying at each age.
Meaning
The term “Expectation of Life” serves as a fundamental measure for life insurance companies to predict the longevity risk and to set appropriate premiums. By using data from mortality tables, insurers can estimate how long individuals are likely to live from a given age, allowing for accurate pricing and risk management.
Etymology
“Expectation” comes from the Latin word “expectationem,” meaning “an awaiting.” Combined with “life,” this phrase succinctly captures the anticipation of remaining lifespan.
Background
The concept originates from actuarial science, historically developed to understand death rates and life expectancy. Mortality tables, also known as life tables, have been crucial since the 17th century when pioneering work in demography and statistics paved the way for modern life insurance.
Key Takeaways
- Actuarial Science Backbone: Actuarial science forms the basis behind the calculations of life expectancy.
- Mortality Tables Usage: These tables chart the likelihood of death for each age, thereby predicting expected future lifetime.
- Insurance Implications: Insurers use expectancy of life to determine premium rates and reserve funds.
Differences and Similarities
- Versus Life Expectancy: Often used interchangeably, life expectancy generally refers to average lifespan predicted at birth, while expectation of life adjusts this expectancy based on survival to a given age.
- Similar Concepts: Both are derived from demographic studies and statistical projections, aiding in the management of financial risk in numerous sectors.
Synonyms
- Life Expectancy
- Average Lifespan
Antonyms
- Mortality Risk
- Premature Death

Frequently Asked Questions
Q1: Why is the expectation of life important in life insurance? A1: It allows insurers to predict how long policyholders will live, ensuring premiums are set appropriately and reserves are maintained for payout obligations.
Q2: How are mortality tables created? A2: Mortality tables are based on historical and statistical data of death rates, often gathered from large demographic studies and insurance claims.
Q3: Do these predictions differ significantly worldwide? A3: Yes, as life expectancy varies greatly due to factors such as healthcare quality, lifestyle, and economic conditions.
Exciting Facts
