AYJ/eɪdʒ/
The stage reached as time passes in a life or existence.

Etymology
Latin aetas meant a lifetime or period of life. That connection survives in age as the amount of time a person or thing has lived or existed.
In context
in 1970 the average US woman had her first baby age 21 and this increased to age 27 by 2022 so the time that we typically have our first baby has increased by six years
