Rows past the average

Many people at this age have already outlived the at-birth life expectancy of their birth year, which is a reminder that averages describe populations, not individuals. The calendar keeps going, and the weeks still ahead are measured in hundreds.

The averages at 79

The Social Security Administration’s 2023 period life table, the one used in the 2026 Trustees Report, puts average remaining life at exactly 79 at 10.4 years for women and 9.0 years for men. That implies an average age at death of about 89.4 and 88.0 respectively, and a halfway point in remaining life at around age 44.

Of people alive at 79, the same table implies that 96% of women and 95% of men would reach 80, 45% of women and 36% of men would reach 90, and 4.1% of women and 1.9% of men would reach 100. A period table assumes today’s death rates hold for the rest of a life; if health keeps improving, the true figures will be somewhat higher.

Averages describe large groups, not you. Health, habits, income, and family history move individual odds far more than a table can show. For a fuller breakdown by age and sex, with the method explained, see Statistical Life Left.
