Then and now: life expectancy for the class of 2009
When you were born, U.S. life expectancy at birth was 78.5 years (80.9 for girls, 76.0 for boys). That number was calculated from the death rates of 2009, and it included every baby born that year, including those who died young. Having made it to about 17, the picture is different: under the SSA’s 2023 period table, the average age at death for someone your age is about 81.7 for women and 76.5 for men, 0.6 years above the 2009 at-birth average.
The same table suggests that, of people born in 2009 who are alive today, about 31% of women and 19% of men would reach 90, and 2.8% of women and 1.0% of men would reach 100. Period tables assume today’s death rates continue; if they keep falling, these figures will prove a little low.
Numbers like these describe a whole birth cohort, not any one person. For a personal statistical breakdown by exact age and sex, see Statistical Life Left.
