What 25 looks like on a life calendar
Each row is one year of age and each box one week. The first 25 rows are filled; the vermilion box is the first week after your 25th birthday.
Building rows
Careers, relationships, and often children arrive in these rows, and weeks tend to fill with obligations. This is the age when a life calendar is most useful as a planning tool: the horizons you set now, such as a home, a family, or a career change, are far enough away to plan for and close enough to count in weeks.
The averages at 25
The Social Security Administration’s 2023 period life table, the one used in the 2026 Trustees Report, puts average remaining life at exactly 25 at 56.9 years for women and 52.1 years for men. That implies an average age at death of about 81.9 and 77.1 respectively, and a halfway point in remaining life at around age 40.
Of people alive at 25, the same table implies that 65% of women and 52% of men would reach 80, 31% of women and 19% of men would reach 90, and 2.8% of women and 1.0% 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.
