1. What is Life Expectancy?

Life expectancy is the statistical measure of the average time an organism is expected to live, based on the year of its birth, current age, and other demographic factors including gender. It is commonly used in actuarial science and public health.

2. How Does the Calculator Work?

The calculator uses actuarial life tables from the Social Security Administration (SSA):

Where:

• \( age \) — Current age in years
• \( gender \) — Male or Female
• \( Table \) — Actuarial life table values from SSA

Explanation: The equation uses published life tables that account for mortality rates at different ages for different genders.

3. Importance of Life Expectancy Calculation

Details: Life expectancy estimates are crucial for retirement planning, insurance underwriting, public health policy, and medical decision-making.

4. Using the Calculator

Tips: Enter your current age in years and select your gender. The calculator will estimate your remaining life expectancy based on actuarial data.

5. Frequently Asked Questions (FAQ)

Q1: How accurate are these estimates?
A: These are population averages based on current mortality rates. Individual results may vary based on health, lifestyle, and other factors.

Q2: Why is female life expectancy higher?
A: Women typically have longer life expectancy due to biological and behavioral factors that result in lower mortality rates at all ages.

Q3: Do these estimates account for future medical advances?
A: No, these are based on current mortality rates only. Future improvements in healthcare could increase life expectancy.

Q4: What's the difference between period and cohort life expectancy?
A: Period life expectancy (shown here) uses current mortality rates, while cohort life expectancy projects future mortality improvements.

Q5: Where can I find more detailed life tables?
A: The Social Security Administration and CDC publish comprehensive life tables with more age categories and demographic breakdowns.
