FAQ
Are generation years official?
No single government body defines every generation. These ranges follow common U.S. research and reference boundaries, with a note that Gen Alpha and Gen Beta are newer labels.
Why can exact ages differ inside the same birth year?
People born in the same calendar year may not have had their birthday yet. The current ranges use the oldest possible and youngest possible ages for each birth-year group.
