Life Expectancy of a 66-Year-Old Woman

By Sohail Manzoor · Updated

20.0 years left on average (about 1,045 weeks), to about age 86.0.

The CDC's 2024 US life table gives a 66-year-old woman 20.0 more years on average, against 17.6 for a man the same age. At 61 a woman had 24.1 years left, so the five years from 61 to 66 took only 4.1 years off her remaining average. Full Social Security retirement age is 66 and 10 months for those born in 1959, and 67 from 1960 on.

How these numbers work

87,113 of every 100,000 babies on the 2024 female table are still alive at 66, and 74,249 at 76. So 85% of 66-year-olds make it to 76. Half have died by 86.9, the median age, and by 95 only 13,135 of the original 100,000 are left.

Life expectancy at 66 questions

How long will a 66-year-old woman live?

20.0 more years is the average on the 2024 table, which takes a 66-year-old woman to about 86.0. Half of women this age live past 86.9, and 1 in 4 past 92.5.

What are the chances a 66-year-old woman lives to 90?

36 in 100, on 2024 US death rates. For 80 it is 75 in 100, and for 100 it is 3.4 in 100.

Is this a prediction for me?

No. It is the average for all women aged 66 in the US on 2024 death rates. Health, habits, income and where you live can move your own number by years either way.
