In the early nineteenth century, global life expectancy was less than 30 years. It’s statistical, infant mortality was very high then. With advances in science and health care, the average is closer to 74 years. Of course, the older you get, the higher your life expectancy is. It sounds weird but it’s true.
The table below comes from Visual Capitalist and the Social Security Office and tells you how many years (statistically) you have left based on your age. It’s kind of fun (well, maybe not for all of us). Smile and take it with a grain of salt. Oh, and women live longer on average.
At birth, an average American baby boy can expect to live till just past 74. But if the boy reaches adulthood, then at 21 he might live to a full year more, past 75. This trend persists even towards the end of life when the years we have left drop rapidly, influenced by the higher likelihood of death.
Interestingly, women outlive men in nearly every country in the world, due to a mix of sociological, behavioral, and biological reasons.
Note: The life expectancy at a given age is the average remaining number of years expected prior to death for a person at that exact age, born on January 1, using the mortality rates for 2020 over the course of their remaining life.
