Which generation am I? Birth year ranges from Gen Z to Boomers

Key points

  • Pew Research Center ranges: Boomers 1946 to 1964, Gen X 1965 to 1980, Millennials 1981 to 1996, Gen Z 1997 to 2012.
  • Baby Boomers are the only generation with an official definition, from the US Census Bureau. Every other range is a research convention.
  • Pew and McCrindle place a birth year in different generations in only 6 years: 1980, 1995, 1996, 2010, 2011 and 2012.
  • Use your birth year, not your age, to find your generation.
  • A generation spans 15 to 19 years, and people within one can differ as much as people in different generations.

Which generation are you?

Type your birth year and the calculator shows your generation under two widely used sets of ranges. The first follows Pew Research Center, which many news articles and surveys quote. The second follows McCrindle Research, which coined the name Generation Alpha. When the two disagree, you will see both answers.

Find your generation

MillennialPew-based: Millennials (Generation Y), born 1981 to 1996. McCrindle: Generation Y (Millennials), born 1980 to 1994. Both sources agree.

How do you work out your generation by hand?

You only need a birth year and the list of ranges. There is no calculation beyond comparing one number with a few boundaries, which is why the answer never depends on your birthday or the date today. The example below uses 1994, a year that sits comfortably inside one generation.

Step by step

Find the generation for someone born in 1994

  1. Take the birth year

    Use the four-digit year of birth: 1994. Ignore the month and the day.

  2. Compare it with the ranges

    1981 to 1996 is the Millennial range in the Pew-based list, and 1994 falls inside it. In McCrindle’s list, 1980 to 1994 is Generation Y, and 1994 falls inside that too.

  3. Check the edge years

    The years where the sources disagree are 1980, 1995, 1996, 2010, 2011 and 2012. 1994 is not among them, so both lists give the same generation.

  4. Write it with the source

    Say “a Millennial, by Pew Research Center’s definition”. Naming the source costs five words and avoids an argument.

Researchers use these groups to compare people at the same stage of life. A generation lets Pew ask how 25-year-olds feel today and how earlier 25-year-olds felt when they were that age, which a plain age bracket cannot do. That is the real purpose of the labels, and it is why the exact boundaries matter less than being consistent about them.

What are the birth years for each generation?

The chart shows the Pew-based ranges used in this guide, from the Greatest Generation to Generation Beta. Each bar is the span of birth years, and the dashed line marks 2026. The generations are roughly the same length: Baby Boomers cover 19 years, Generation X and Millennials 16 years each, and Generation Z 16.

  1. Greatest Generation 1901 to 1927

  2. Silent Generation 1928 to 1945

  3. Baby Boomers 1946 to 1964

  4. Generation X 1965 to 1980

  5. Millennials (Generation Y) 1981 to 1996

  6. Generation Z 1997 to 2012

  7. Generation Alpha 2013 to 2024

  8. Generation Beta 2025 to 2039

Birth-year ranges by generation, Pew-based. The dashed line marks 2026.

Ages follow from the ranges. The table shows the age each generation reaches in 2026 and ten years later. It uses the birth year only, so someone can be a year younger than shown until their birthday.

Who decides where a generation starts and ends?

Nobody does, which is why the ranges differ between websites. A generation is a label for people born in a similar span of years who lived through similar events, and researchers pick the cutoffs that suit their work. Pew Research Center chose 1996 as the last birth year for Millennials so the group would stay analytically useful, and it describes such cutoffs as not an exact science. McCrindle Research, which publishes its generation ranges in an infographic (PDF), draws the lines one to three years earlier. Neither is wrong. They are different conventions for the same underlying fact, which is that people are born continuously and a generation boundary is a line drawn through a smooth stream of birth years.

Pew explained its choice of 1996 with events as well as numbers. It notes that most Millennials were between 5 and 20 years old during the 11 September 2001 attacks, so many were old enough to grasp them, while most of Generation Z have little or no memory of them. The iPhone launched in 2007, when the oldest members of Generation Z were 10, so they grew up with mobile internet in a way Millennials did not. The choice also keeps Millennials at 16 years, the same length as Generation X.

Pew is open about the limits. It expects the evidence to show a continuum across generations rather than a sharp threshold, which is why the youngest and oldest members of a generation can feel closer to their neighbours than to their own group.

Pew Research Center

Pew Research Center, a US research organisation, counts Millennials as 1981 to 1996 and starts Generation Z in 1997. It says generational cutoffs are not an exact science, and that Baby Boomers, at 19 years, are the only generation officially designated by the US Census Bureau.

GenerationBornYears
Baby Boomers1946 to 196419
Generation X1965 to 198016
Millennials (Generation Y)1981 to 199616
Generation Z1997 to 201216

Pew sets the ranges up to Generation Z. From 2013 this guide continues them with Generation Alpha and Generation Beta.

McCrindle Research

McCrindle Research, an Australian social research group, uses 1980 to 1994 for Generation Y (Millennials), 1995 to 2009 for Generation Z and 2010 to 2024 for Generation Alpha. It coined the name Generation Alpha, and also proposed Generation Beta for 2025 to 2039.

Each of its recent generations spans 15 years.

What if you were born on the edge of two generations?

People born within a year or two of a boundary are on a cusp, and they often feel they belong to both neighbouring groups. Comparing the two lists year by year shows how small the problem is. Between 1946 and 2024, only 6 birth years change generation depending on the source: 1980, 1995, 1996, 2010, 2011 and 2012. Everyone else lands in the same generation either way. In practice that means almost anyone can quote their generation without a caveat, and only those born in the edge years need to name their source.

Are generations real, official groups?

They are useful labels, not official categories, and they say less about any one person than headlines suggest. Pew points out that differences within a generation can be as great as the differences between generations.

Myth or fact

Myth or fact?

Myth Every generation has an official definition.

Fact Only Baby Boomers do. The US Census Bureau designated them (1946 to 1964). The other ranges are conventions chosen by research groups.

Myth Everyone in a generation thinks and behaves alike.

Fact Pew describes generations as inherently diverse, and says the youngest and oldest members of a group may feel closer to the neighbouring generation than their own.

Myth Millennials and Generation Y are different groups.

Fact They are two names for the same generation. Generation Y was the earlier label, and Millennials is now the more common one.

Myth Everyone agrees where Generation Z ends.

Fact They do not. Pew ends it in 2012. McCrindle ends it in 2009 and starts Generation Alpha in 2010.

Quiz

Test yourself

  1. Using Pew Research Center’s ranges, which generation is someone born in 1990?

    • Generation X
    • Millennial
    • Generation Z
    • Baby Boomer
    Answer

    B. Pew counts Millennials as 1981 to 1996, and 1990 sits in the middle of that range.

  2. Which generation is the only one officially designated by the US Census Bureau?

    • Baby Boomers
    • Generation X
    • Millennials
    • Generation Z
    Answer

    A. Pew notes that Baby Boomers (1946 to 1964) are the only generation with an official designation. The rest are research conventions.

  3. Someone is born in 1996. Which generation is that under McCrindle’s ranges?

    • Generation X
    • Generation Z
    • Generation Alpha
    • Baby Boomer
    Answer

    B. McCrindle’s Generation Z runs 1995 to 2009. Pew’s range would make the same person a Millennial, because Pew’s Millennials run to 1996.

  4. Between 1946 and 2024, how many birth years change generation depending on whether you use Pew or McCrindle?

    • 2
    • 6
    • 10
    • 20
    Answer

    B. Only 6: 1980, 1995, 1996, 2010, 2011 and 2012. Every other birth year lands in the same generation in both lists.

  5. How many birth years does Pew’s Millennial range cover?

    • 12
    • 15
    • 16
    • 19
    Answer

    C. 1981 to 1996 is 16 birth years, counting both the first and the last.

Common questions

What generation is someone born in 1995?

It depends on the source. Pew Research Center puts 1995 in the Millennial range (1981 to 1996). McCrindle Research puts it at the start of Generation Z (1995 to 2009). 1995 is one of 6 birth years where the two sources disagree.

What are Xennials and Zillennials?

They are informal nicknames for people near a boundary. Xennials sit between Generation X and Millennials, and Zillennials between Millennials and Generation Z. Neither is an official category and sources give different year ranges, so treat them as descriptions rather than groups.

How long does a generation last?

Researchers usually draw them 15 to 19 years wide. Pew Research Center counts 19 years for Baby Boomers (1946 to 1964) and 16 years for both Generation X and Millennials. McCrindle Research's recent generations are 15 years each.

Are generation labels the same in every country?

No. The common labels were built around American or Australian data and the events people there lived through. Other countries have their own names and boundaries, shaped by their own history, so a birth year can place someone in a different group elsewhere.

When does Generation Alpha begin?

In 2010 by McCrindle Research's definition, which coined the name. Others begin it in 2013, straight after Pew's end for Generation Z in 2012. In McCrindle's scheme Generation Beta starts in 2025.

Should I use my age or my birth year to find my generation?

Use your birth year. A generation is a range of birth years, so your age changes every year while your generation does not. Someone who turns 30 in 2026 was born in 1996, and is a Millennial by Pew's range whatever their age next year.
