What Generation Am I? Birth Years for Every Generation

What generation am I? Find your birth year in the table below. Using the Pew Research Center’s widely cited ranges, you are a Baby Boomer if you were born from 1946 to 1964, Generation X from 1965 to 1980, a Millennial from 1981 to 1996, and Generation Z from 1997 to 2012. Children born from 2010 to 2024 are usually called Generation Alpha, and babies born since 2025 are Generation Beta.

One warning before you settle on an answer: only one of these generations has an official start and end date. The rest are conventions, and different researchers draw the lines in different places. This guide shows the most-used ranges, explains why they disagree, and helps you work out where you fit if you were born near a boundary.

What generation am I? The quick table

Generation	Birth years (Pew Research Center)	Age reached in 2026
Silent Generation	1928 to 1945	81 to 98
Baby Boomers	1946 to 1964	62 to 80
Generation X	1965 to 1980	46 to 61
Millennials (Gen Y)	1981 to 1996	30 to 45
Generation Z	1997 to 2012	14 to 29
Generation Alpha	2010 to 2024 (McCrindle)	2 to 16
Generation Beta	2025 to 2039 (McCrindle)	0 to 1

You can also work out the day of the week you were born.

Many Gen Z voters born in 2008 have their first midterm election in 2026.

The “age reached in 2026” column shows the age each person turns during 2026, the same simple birth-year subtraction used in our guide born in 2008, how old am I. For your exact age today in years, months and days, use the age calculator.

Which generations are official?

Only the Baby Boomers. The Pew Research Center notes that the Boomers are the only generation officially designated by the U.S. Census Bureau, based on the surge in births after World War II in 1946 and the significant drop in birth rates after 1964.

Every other generation is defined by researchers. Pew explains that there are no comparably definitive thresholds for later generations, and it chose its Millennial and Gen Z cutoffs for analytical reasons: someone born in 1996 was too young to understand the significance of the 9/11 attacks and grew up as smartphones and social media spread. Pew also says generational cutoffs are not an exact science and are meant as a tool for analysis, not a rigid rule.

Why different sources give different years

Search “what generation am I” and you will quickly find two sets of dates that do not match. The main reason is that two organizations publish the most-quoted ranges.

Generation	Pew Research Center	McCrindle (Australia)
Millennials / Gen Y	1981 to 1996	1980 to 1994
Generation Z	1997 to 2012	1995 to 2009
Generation Alpha	not defined	2010 to 2024
Generation Beta	not defined	2025 to 2039

McCrindle, the Australian research firm that named Generation Alpha, uses 15-year spans. Its articles define Gen Y as 1980 to 1994, Gen Z as 1995 to 2009, Generation Alpha as 2010 to 2024 and Generation Beta as 2025 to 2039.

So a person born in 1995 is a Millennial by Pew’s dates and Gen Z by McCrindle’s. Someone born in 2011 is Gen Z under Pew and Gen Alpha under McCrindle. Neither is wrong; they are using different rulers. Most US media follow Pew for Boomers through Gen Z and McCrindle for Alpha and Beta, which is why the table above mixes the two.

Born on a boundary? The “cusp” years

People born within a couple of years of a cutoff often feel they belong to both groups. Common nicknames include:

• Xennials for people born around the late 1970s and early 1980s, between Gen X and Millennials.
• Zillennials for people born around the mid-1990s, between Millennials and Gen Z.

These labels are informal, and no standard dates exist for them. If you were born in 1980, 1981, 1996 or 1997, the honest answer is that your generation depends on which source you use, and your own experience counts as much as the label.

What generation am I if I was born in…

Here are the answers people look up most often, using Pew’s ranges for 1928 to 2012 and McCrindle’s for Alpha and Beta:

• 1964: Baby Boomer, the last Boomer birth year.
• 1965: Generation X, the first Gen X year.
• 1980: Generation X under Pew; Gen Y under McCrindle.
• 1981: Millennial.
• 1990: Millennial.
• 1995: Millennial under Pew; Gen Z under McCrindle.
• 1996: Millennial, the last Millennial year under Pew.
• 1997: Generation Z.
• 2000: Generation Z.
• 2008: Generation Z.
• 2010 to 2012: Gen Z under Pew; Generation Alpha under McCrindle.
• 2013 to 2024: Generation Alpha.
• 2025 or later: Generation Beta.

How old is each generation now?

Generational ages shift every year, which matters if you are writing a report, planning a family reunion or running a survey. In 2026:

• The oldest Millennials turn 45 and the youngest turn 30.
• The oldest Gen Z turn 29, so Gen Z now spans teenagers to people approaching 30.
• The youngest Baby Boomers turn 62, and the oldest turn 80.
• The oldest Generation Alpha children turn 16.

To find an exact age for someone born on a specific date, rather than a whole birth year, use the age calculator. For long spans, the age in days calculator and age in weeks calculator give the same result in other units. If you need the combined age of a whole family or team, our recent guide to cumulative age shows the method.

Where the generation names come from

The labels themselves have different origins, which is another reason their dates do not line up neatly:

• Baby Boomers are named for the post-war baby boom, the jump in US births from 1946 that the Census Bureau uses to define the group.
• Generation X was popularized by Douglas Coupland’s 1991 novel Generation X: Tales for an Accelerated Culture, and the “X” stuck as a name for the group after the Boomers.
• Millennials are named for coming of age around the turn of the millennium. They are also called Generation Y, the letter after X, which is the name McCrindle uses.
• Generation Z continued the alphabet after Y.
• Generation Alpha and Beta restart with the Greek alphabet. McCrindle says it chose the names to mark the first generations shaped by an entirely different world, and that Gamma and Delta would follow if the naming sticks.

Using generation labels in reports and surveys

If you are using generations in a school project, a workplace survey or a marketing report, a little care makes your work easier to trust. Pew itself announced in May 2023 that it would report on generations more selectively, using generational comparisons only when long-term data let it compare people at similar life stages, and otherwise grouping people by age or birth decade instead.

Practical tips:

1. State the source and the birth years you used, for example “Gen Z (born 1997 to 2012, Pew)”.
2. Group people by birth year, not by the age they say they feel.
3. Remember that differences between age groups may reflect life stage, not generation. A 25-year-old today and a 25-year-old in 1995 may have more in common than either has with their parents.
4. For small groups, a simple age band such as 18 to 29 is often clearer than a generation label.

Generations around the world

Generation labels come mostly from US and Australian research, and they fit some countries better than others. The Baby Boom, for example, was a post-war birth surge in the United States, and other countries’ booms began and ended in different years. Researchers outside the US sometimes use their own local cohort names tied to national events.

Age itself is also counted differently in some places. Our article on Western vs East Asian age explains why the same person can have two different ages depending on the system. And because generations are based on birth year, not exact birth date, a person born on 1 January and another born on 31 December of the same year share a generation despite being nearly a year apart.

How to work out your generation yourself

1. Note your birth year. The month and day do not matter for generation labels.
2. Find the range that contains it in the Pew table (1928 to 2012) or the McCrindle table (Alpha and Beta).
3. If you are within two years of a boundary, check both sources and pick the one your audience uses.
4. Subtract your birth year from the current year to see the age you reach this year.
5. For a precise age, enter your full birth date in the age calculator.

Generation vs other age milestones

A generation label tells you something about the era you grew up in, not about legal or practical milestones. Those depend on your exact date of birth. Retirement and Medicare planning, for example, turn on the month you reach 65; our guide to when you turn 65 shows how the enrollment window is counted. School start dates depend on cutoff dates, covered in school age cutoffs explained. And for a lighter milestone, our new guide to the half birthday shows how to find the date six months after your birthday.
