What is an Actuarial Life Table?§
An actuarial life table is a statistical tool that provides insights into the likelihood of an individual dying before their next birthday, based on their current age. It plays a crucial role in the life insurance industry, allowing providers to assess risks and calculate premiums.
Key Features:§
- Survival Probability: It shows the probability of surviving to different ages.
- Gender-Specific: Tables are often created separately for men and women due to differing mortality rates.
- Life Expectancy: Helps estimate the remaining years an individual is expected to live.
Formal Definition§
An actuarial life table is a table providing statistics on mortality and survival for a defined population, typically segmented by age and gender, thereby serving to predict life expectancy and inform insurance practices.
| Feature | Actuarial Life Table | Mortality Table |
|---|---|---|
| Purpose | Estimates life expectancy | Estimates mortality risk |
| Gender Specificity | Yes (separate for men and women) | Often combined, but can be gendered |
| Usage | Used mainly by life insurance companies | Used in various fields including health and finance |
| Data Representation | Probability of survival at different ages | Rate of mortality over age intervals |
