What Generation Am I? — The Quick Answer
Match the birth year to a generation's range. Using the widely-cited Pew Research boundaries: Millennials are 1981–1996 and Gen Z is 1997–2012, with Gen X before and Gen Alpha after.

Generations by birth year
| Generation | Birth years |
|---|---|
| Baby Boomers | 1946–1964 |
| Generation X | 1965–1980 |
| Millennials (Gen Y) | 1981–1996 |
| Generation Z | 1997–2012 |
| Generation Alpha | 2013–2024 |
| Generation Beta | 2025–2039 |
Generation boundaries are cultural shorthand, not official definitions, and different researchers draw the lines in slightly different years. These ranges follow the Pew Research Center for Boomers through Gen Z, with Alpha and Beta per common demographic naming.

Formula
Boomers 1946–1964 · Gen X 1965–1980 · Millennials 1981–1996 · Gen Z 1997–2012 · Gen Alpha 2013–2024 · Gen Beta 2025–2039
Variables
Boomers to Gen Z
The Pew Research Center defines Boomers (1946–1964), Gen X (1965–1980), Millennials (1981–1996), and Gen Z (1997–2012). These are the most widely cited boundaries in the US and beyond.
The newest generations
Generation Alpha (from 2013) and Generation Beta (from 2025) are more recent labels, popularised by social researcher Mark McCrindle, since the major institutions haven't fixed official ranges yet.
Note: Because the cut-off years are approximate, people born near a boundary (a 'cusp' — such as 1996–1997 between Millennials and Gen Z) often identify with either generation. Treat the label as a guide, not a rule.

Frequently Asked Questions
What generation am I if I was born in 1990?
A Millennial. The Millennial generation (also called Gen Y) runs from 1981 to 1996 under the widely-used Pew Research definition, so a 1990 birth year sits comfortably in the middle of it.
What years are Gen Z?
Generation Z is commonly defined as those born from 1997 to 2012 (Pew Research). People born right at the start, around 1997, sometimes feel like they straddle the Millennial/Gen Z boundary — a 'Zillennial' cusp.
Are generation years official?
No. There's no single official authority on generation boundaries, and different organisations use slightly different years. The Pew Research Center's ranges are the most widely cited, which is what this calculator uses for Boomers through Gen Z; the newest generations (Alpha, Beta) follow common demographic naming.
What comes after Generation Z?
Generation Alpha (born roughly 2013–2024), followed by Generation Beta (from 2025). These labels, coined by demographer Mark McCrindle, continue the alphabet using Greek letters now that the Latin alphabet's X, Y, and Z have been used.
