What 17 looks like on a life calendar
Each row is one year of age and each box one week. The first 17 rows are filled; the vermilion box is the first week after your 17th birthday.
The last rows of childhood
By the teenage years a person has filled most of the rows they will spend living with their parents. For parents, the remaining weeks before a child leaves home are often fewer than they assume; counting them, once, tends to change how a few weekends get spent.
The averages at 17
The Social Security Administration’s 2023 period life table, the one used in the 2026 Trustees Report, puts average remaining life at exactly 17 at 64.7 years for women and 59.5 years for men. That implies an average age at death of about 81.7 and 76.5 respectively, and a halfway point in remaining life at around age 40.
Of people alive at 17, 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.
