Generations defined by name, birth year, and ages in 2020

What are the ages of the generations in 2020? 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 2020:

BornAges
Gen Z1997 – 20128 – 23
Millennials1981 – 199624 – 39
Gen X1965 – 198040 – 55
Boomers II1955 – 196456 – 65
Boomers I1946 – 195466 – 74
Post War1928 – 194575 – 92
WW II1922 – 192793 – 98

We occasionally 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., Boomers II are just young enough to have missed being drafted into war.
