According to global statistics, a person born in 2021 could expect to live approximately 73.2 years at the time of their birth. Someone born in 2021 who is still alive today is 4–5 years old, which means they have lived roughly 7% of their originally expected lifespan.

Modern medicine and improved living conditions mean that people who survived childhood often outlive their birth-year estimates. Learn more in our life expectancy trends article.
