What 70 looks like on a life calendar
Each row is one year of age and each box one week. The first 70 rows are filled; the vermilion box is the first week after your 70th birthday.
Chosen rows
For many, these rows are the first in decades not defined by a job, and there are more of them than most people expect. Life tables show that surviving to this age raises the average expected life span well above the at-birth figure, so planning for long, active years is realistic rather than optimistic.
The averages at 70
The Social Security Administration’s 2023 period life table, the one used in the 2026 Trustees Report, puts average remaining life at exactly 70 at 16.8 years for women and 14.7 years for men. That implies an average age at death of about 86.8 and 84.7 respectively, and a halfway point in remaining life at around age 43.
Of people alive at 70, the same table implies that 78% of women and 71% of men would reach 80, 37% of women and 27% of men would reach 90, and 3.3% of women and 1.4% 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.
