How does human life expectancy change with age?
I think you might be looking for period life tables


  A period life table is based on the mortality experience of a population during a relatively short period of time. Here we present the 2014 period life table for the Social Security area population. For this table, the period life expectancy at a given age is the average remaining number of years expected prior to death for a person at that exact age, born on January 1, using the mortality rates for 2014 over the course of his or her remaining life.
