“The latest, best guesses for U.S. lifespans come from a study (PDF) released this month by the Society of Actuaries: The average 65-year-old American man should die a few months short of his 86th birthday, while the average 65-year-old woman gets an additional two years, barely missing age 88.
This new data turns out to be a disappointment. Over the past several years, the health of Americans has deteriorated—particularly that of middle-aged non-Hispanic whites. Among the culprits are drug overdoses, suicide, alcohol poisoning, and liver disease, according to a Princeton University study issued in December.
Partly as a result, the life expectancy for 65-year-olds is now six months shorter than in last year’s actuarial study. Longevity for younger Americans was also affected: A 25-year-old woman last year had a 50/50 chance of reaching age 90. This year, she is projected to fall about six months short. (The average 25-year-old man is expected to live to 86 years and 11 months, down from 87 years and 8 months in last year’s estimates.) Baby boomers, Generation X, and yes, millennials, are all doing worse.”
