Life expectancy by age

How long does a 81 year old live?

A woman of 81 in the US reaches 90.3 on average, and a man 89.1, by the 2024 US life table. That's 9.3 and 8.1 more years. Half of 81-year-old women live past 90, and half of men past 89.

Why it's higher than 79

The 79.0 years you hear about is the US average at birth in 2024. By 81, you've already passed the ages where some people born the same year died, so the average age you reach is higher: 90.3 for women and 89.1 for men.

What moves your own number

This is the average for everyone in the US aged 81, smokers and marathon runners alike. In a study of 123,219 US health professionals, people with five healthy habits at 50 could expect 12 to 14 more years than people with none (Li 2018).
