How long does the average person live?


In 2012, the at-birth global life expectancy was 70 years, according to the World Health Organization. Life expectancy numbers are affected by a number of factors, including where a person lives and how old that person is at the time expectancy is calculated.

The United States Social Security Administration provides a life expectancy calculator that lets people estimate their own life expectancies for financial planning purposes. The calculator uses a person's gender and date of birth, along with historical statistics, to return an estimate on how much longer a person is likely to live. According to the SSA's calculator, a person turning 65 in early June 2014 would live an additional 19 or 21 years on average depending on gender.
