1. What is Life Expectancy?

Life expectancy is a 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.

2. How Does the Calculator Work?

The calculator uses demographic data to estimate remaining life years:

Where:

• \( LE \) — Life expectancy in years
• \( current\_age \) — Current age in years

Explanation: The calculation considers average remaining years based on actuarial tables and demographic data.

3. Importance of Life Expectancy Estimation

Details: Life expectancy estimates help in retirement planning, health care decisions, and understanding population health trends.

4. Using the Calculator

Tips: Enter your current age in years. The value must be valid (between 0-120 years).

5. Frequently Asked Questions (FAQ)

Q2: What factors affect life expectancy?
A: Genetics, lifestyle choices, healthcare access, socioeconomic status, and environmental factors all influence life expectancy.

Q3: Does this account for gender differences?
A: A more sophisticated calculator would include gender, as women typically live longer than men on average.

Q4: Why does life expectancy increase as you get older?
A: As you survive higher-risk younger years, your remaining life expectancy may actually increase slightly.

Q5: How often is life expectancy recalculated?
A: National statistics are typically updated annually based on current mortality data.
