Generations defined by name, birth year, and ages in 2023
What are the ages of the generations in 2023? If you do some research, you’ll find that dates overlap and names vary. While we hear generational terms all the time, the definitions are not official. However, based on widespread consensus as well as new Gen Z analysis by the Pew Research Center, and the one generation defined by the U.S. Census Bureau (Baby Boomers), these are the birth years and ages of the generations you’ll want to use in 2023.
Note: Generation names are based on when members of that generation become adults (18-21).
|Gen Z||1997 – 2012||11 – 26|
|Millennials||1981 – 1996||27 – 42|
|Gen X||1965 – 1980||43 – 58|
|Boomers II (a/k/a Generation Jones)*||1955 – 1964||59 – 68|
|Boomers I*||1946 – 1954||69 – 77|
|Post War||1928 – 1945||78 – 95|
|WWII||1922 – 1927||96 – 101|
*We increasingly break up Boomers into two different cohorts because the span is so large, and the oldest of the generation have different sensibilities than the younger. In the U.S., Generation Jones (Boomers II) are just young enough to have missed being drafted into war.
Thinking we’ve got it all wrong? Many people are confused by the labels demographers assign to the generations, and some tell us we’ve made a mistake. We haven’t. In fact, this page has been cited in newspapers including USA Today.

In short, the generation names are based on when members of that generation become adults (18-21).
