Life expectancy is another use of mortality data, an estimate of how many more years a person with certain characteristics (current age, sex, and so forth) is likely to live or what age they are likely to attain before they die. Life expectancy estimates have many uses in the insurance industry and elsewhere. For example, the Internal Revenue Service publishes life expectancy tables that taxpayers must use to determine their annual required minimum distributions (RMDs) from their retirement accounts. In its most recent tables, for example, a newborn has a life expectancy of another 84.6 years, while someone who is 120 or older (the top limit of the table) has a life expectancy of one more year.
