Then and now: life expectancy for the class of 1991
When you were born, U.S. life expectancy at birth was 75.5 years (78.9 for girls, 72.0 for boys). That number was calculated from the death rates of 1991, and it included every baby born that year, including those who died young. Having made it to about 35, the picture is different: under the SSA’s 2023 period table, the average age at death for someone your age is about 82.4 for women and 78.1 for men, 4.7 years above the 1991 at-birth average.
The same table suggests that, of people born in 1991 who are alive today, about 31% of women and 20% 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.
