Every Generation, Birth Years and Ages
All eight named generations in one table with their birth years, current ages and how many years each band covers — the reference the rest of the site is built on.
The eight named generations run from the Greatest Generation (1901–1927) to Generation Beta (2025–2039), and their bands are not equal — Generation Z covers thirteen birth years while Baby Boomers cover nineteen.
Every Generation, Birth Years and Ages
Frequently asked
How many generations are there?
Eight are commonly named, from the Greatest Generation to Generation Beta. The labels are conventions and only the most recent few have a single agreed author.
Why are the bands different lengths?
Because they were named at different times by different people, mostly retrospectively. There is no rule that a generation must be fifteen years long.
