Life Expectancy of a 100-Year-Old Man

By Sohail Manzoor · Updated Nov 2, 2026

2.0 years left on average (about 106 weeks), to about age 102.0.

The CDC's 2024 US life table gives a 100-year-old man 2.0 more years on average, against 2.3 for a woman the same age. At 95 a man had 2.9 years left, so the five years from 95 to 100 took only 0.9 years off his remaining average.

How these numbers work

1,170 of every 100,000 babies on the 2024 male table are still alive at 100. The table stops there, so it gives one average for every age from 100 up.

Life expectancy at 100 questions

How long will a 100-year-old man live?

2.0 more years is the average on the 2024 table, which takes a 100-year-old man to about 102.0.

How many people live to 100?

On the 2024 US tables, 1,170 of every 100,000 babies would reach 100. For boys the count is 1,170 and for girls 2,966.

Is this a prediction for me?

No. It is the average for all men aged 100 in the US on 2024 death rates. Health, habits, income and where you live can move your own number by years either way.
