What 64 looks like on a life calendar
Each row is one year of age and each box one week. The first 64 rows are filled; the vermilion box is the first week after your 64th birthday.
Approaching the turn
For many people these rows lead up to a change in working life. It is a good time to sketch the next chapter on the calendar as a future era, because the weeks after full-time work are often more numerous than people plan for: under the current life table, a 60-year-old's average is more than twenty more years.
The averages at 64
The Social Security Administration’s 2023 period life table, the one used in the 2026 Trustees Report, puts average remaining life at exactly 64 at 21.5 years for women and 18.8 years for men. That implies an average age at death of about 85.5 and 82.8 respectively, and a halfway point in remaining life at around age 42.
Of people alive at 64, the same table implies that 73% of women and 63% of men would reach 80, 35% of women and 24% of men would reach 90, and 3.1% of women and 1.2% 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.
