What next?
A generation label comes from a birth year. These are the related date tools.
How to use this calculator
- Type your year of birth — or your age, and the year fills itself in.
- See your generation, the years it spans and the century you were born in.
- Scroll the full list to see where you sit among every generation.
What your result means
A “generation” groups people born in a roughly 15-to-20-year window who came of age with the same technology, economy and world events. Your birth year drops you into one of these named cohorts. The boundaries aren’t laws — they’re conventions — so if you were born near an edge you may feel like a bit of both (a “cusper”).
Why this one is different
The birth-year span behind the label is printed next to it, so it is clear why a particular year lands where it does, and a note appears for anyone born near a boundary. Generation cut-offs are publishing conventions rather than standards, and sources move them by a couple of years, which the page says rather than hides.
Who decides these names?
There is no official body that sets generation years — researchers, marketers and the media settled on them over time. The most cited ranges come from the Pew Research Center. Newer labels like Generation Alpha and Beta were popularised by demographer Mark McCrindle, whose team continues the alphabet as each new cohort arrives.
Every generation at a glance
Ranges follow common (mainly Pew Research) definitions and vary slightly by source.
Worked example
Someone born in 1996, and their sibling born in 1997:
Born 1997 → Generation Z (1997–2012)
Two siblings a year apart, on opposite sides of a generational line. That is the honest limitation of the whole exercise: the boundaries are drawn by researchers looking for cohorts that experienced formative events at the same age, not by anything that changes on 1 January. Anyone born within two or three years of a cut-off will usually recognise themselves in both descriptions — the "Zillennial" label exists for exactly this reason.
What a generation label can and cannot tell you
A generational cohort is a shorthand for shared context: the technology that existed when you were a teenager, the economy you entered work in, the events that were formative rather than remembered. Used that way it is genuinely informative. Used to predict an individual's attitudes or abilities, it performs about as well as a star sign — the variation within any cohort dwarfs the difference between cohorts.
The boundaries themselves are not official. Pew Research Center's ranges are the most widely cited in English-language research and are the ones used here, but Strauss and Howe, McCrindle and various national statistics agencies all draw the lines differently, sometimes by several years. Anyone born within a year or two of a boundary will recognise traits from both sides.
The word also carries a second, older meaning: the gap between parent and child, conventionally 25 to 30 years in genealogy. That is the figure to use for estimating how far back a family tree reaches, and it has nothing to do with the named cultural cohorts — a useful distinction when reading old records that describe someone as being "of the third generation" of a family.
Frequently asked questions
Are generation birth years exact?＋
No. There is no official standard. These ranges follow widely used definitions such as Pew Research Center’s, and boundaries can vary by a year or two between sources.
What generation comes after Gen Alpha?＋
Generation Beta, covering births from about 2025. Generation Gamma is the next projected label, expected from around 2040.
Who defines the generation boundaries?＋
There is no official authority. Pew Research Center's ranges are the most widely cited in the English-speaking world, and those are the ones used here, but other researchers use different cut-offs.
What if I was born on a boundary year?＋
You are what researchers call a cusper, and people born within a year or two of a boundary often identify with either side. The label describes a cohort's shared context, not an individual's traits.
Why do generations matter at all?＋
They are a shorthand for the technology, economics and events people encountered at formative ages. Used carefully that is informative; used to predict an individual's behaviour it is little better than astrology.
How long is a generation in family terms?＋
Genealogically, about 25 to 30 years between parent and child, which is a different meaning from the named cultural cohorts and is the figure to use for family tree estimates.

Assumptions & limitations
Generation boundaries are a convention, not a fact:
- Different researchers use different cut-offs. This tool follows the Pew Research Center definitions, which are the most widely cited — but a person born in a boundary year can reasonably identify either way.
- The cohorts are US-centric in origin and map imperfectly onto other countries, whose formative events differ.
- Generational labels describe a shared context, not a personality. Within-generation variation is far larger than the difference between generations.
