Then and now: life expectancy for the class of 2025
Official U.S. life expectancy figures for 2025 have not been finalized yet. The most recent CDC/NCHS figure, for 2023, is 78.4 years at birth: 81.1 for girls and 75.8 for boys. Under the SSA’s 2023 period table, a child who is 1 today has an average expected life span of about 81.5 years for girls and 76.3 for boys.
The same table suggests that, of people born in 2025 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.
