What 5 looks like on a life calendar
Each row is one year of age and each box one week. The first 5 rows are filled; the vermilion box is the first week after your 5th birthday.
The school-year rows
From here, rows start to line up with school years, and a week becomes a unit a child can understand: five school days and a weekend. Showing a child their own calendar is a good way to make big numbers concrete, and many families find it a gentle way to talk about time without talking about endings.
The averages at 5
The Social Security Administration’s 2023 period life table, the one used in the 2026 Trustees Report, puts average remaining life at exactly 5 at 76.6 years for women and 71.3 years for men. That implies an average age at death of about 81.6 and 76.3 respectively, and a halfway point in remaining life at around age 39.
Of people alive at 5, the same table implies that 65% of women and 51% 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.
