Definition
The Yearly Probability of Dying is a statistical estimate that quantifies the likelihood of an individual, based on factors such as age and sex, dying within a one-year period. This concept is fundamental in fields like public health, actuarial science, and insurance.
Main Concepts:
- It is often derived from mortality tables.
- It serves various industries, particularly health studies and the insurance sector in evaluating risks and setting premiums.
| Yearly Probability of Dying | Yearly Probability of Living |
|---|---|
| Measures the likelihood of death within a year | Measures the likelihood of surviving the year |
| Often used in life insurance and annuities | Useful for assessing longevity and quality of life |
| Typically increases with age | Typically decreases with age |
Example
For instance, if a 65-year-old man has a yearly probability of dying of 0.005 (or 0.5%), then the probability of living for that year is simply 1 - 0.005 = 0.995 (or 99.5%).

Fun Facts:
- Life expectancy has increased over the last century thanks to improved healthcare and living conditions—proof that living well can extend life’s warranty! 🤣
- The concept of mortality tables originated in the late 17th century, so we’ve been crunching mortality numbers longer than we’ve been using calculators!
