What 87 looks like on a life calendar
Each row is one year of age and each box one week. The first 87 rows are filled; the vermilion box is the first week after your 87th birthday.
The far end of the page
These are the rows that many life calendars do not even print. Reaching them means outliving most of one's birth cohort; each week is, statistically, a remarkable one. For families, this is also an age when a filled-in calendar becomes a family record worth keeping.
The averages at 87
The Social Security Administration’s 2023 period life table, the one used in the 2026 Trustees Report, puts average remaining life at exactly 87 at 6.1 years for women and 5.2 years for men. That implies an average age at death of about 93.1 and 92.2 respectively, and a halfway point in remaining life at around age 46.
Of people alive at 87, the same table implies that 72% of women and 66% of men would reach 90, and 6.5% of women and 3.5% 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.
