What is Life Expectancy?

What is Life Expectancy?

Life Expectancy at Birth Statistics — Found Here

Life expectancy may be different for each subset of the population, based on risk factors and age. It is most commonly discussed as the average for an entire population or a specific age group, without regard for specific health risks that may be present.

Life expectancy may come into play in discussions of the economy, the health of a population, or for individual planning purposes. Actuarial tables with life expectancy are published by government entities and private companies. The most basic variable will be age.

A 30 year old today may be expected to live to an older age than an older person today, in general, while a newborn may have a slightly lower life expectancy due to infant mortality risk, which averages in to the total number. Life insurance carriers will give each applicant a risk rating based on current health, health history, habits, and some heredity.

This risk rating will be coupled with an age-based life expectancy to arrive at their final, best-guess estimate of when a person with that profile and age will die, on average. About 50% of a group will die before the life expectancy for a group, and about 50% will die after the life expectancy of the group, if the actuaries are correct.

If medical technology and nutrition improve significantly, people today could significantly outlive their life expectancies. Life insurance companies, the Social Security Administration, and organizations like the World Health Organization (WHO) study life expectancy more than others.

Life expectancy at Birth (LEB) is a commonly used statistic, which is the estimated life expectancy of each person in a population at birth.
