If you have ever wondered whether you are a Baby Boomer, Gen X, Millennial, Gen Z, or part of a newer generation, the answer depends on your birth year and which generational framework you use.
Generation names help researchers, marketers, educators, families, and businesses understand broad groups of people who grew up during similar periods of social, economic, and technological change.
This guide explains the generation names and years from the Greatest Generation through Generation Beta.
It also explains why different sources sometimes use different birth-year ranges, what shaped each generation, and how to identify your generation without relying on stereotypes.
For commonly used U.S. definitions, Pew Research Center identifies the Silent Generation as 1928–1945, Baby Boomers as 1946–1964, Gen X as 1965–1980, and Millennials as 1981–1996 in much of its later research.
For newer cohorts, Generation Z is generally placed after Millennials, while McCrindle uses 2010–2024 for Generation Alpha and 2025–2039 for Generation Beta.
The important point is that generations are useful cultural groupings, not strict scientific categories.
Your birth year can place you near a generational boundary, but your upbringing, country, family, technology, and life experiences also shape who you are.
Generation Names and Years at a Glance
Here is a simple generation chart to make the timeline easy to understand:
| Generation | Common Birth Years | Approximate Age in 2026 |
|---|---|---|
| Greatest Generation | 1927 and earlier | 99+ |
| Silent Generation | 1928–1945 | 81–98 |
| Baby Boomers | 1946–1964 | 62–80 |
| Generation X | 1965–1980 | 46–61 |
| Millennials | 1981–1996 | 30–45 |
| Generation Z | 1997–2009* | 17–29 |
| Generation Alpha | 2010–2024* | 2–16 |
| Generation Beta | 2025–2039* | 0–1 |
*Birth-year boundaries for Gen Z and newer generations vary by source. The ranges shown here provide a practical timeline rather than a universal rule.
Pew Research Center emphasizes that generational boundaries should be treated as guidelines rather than hard-and-fast divisions. Its widely used U.S. framework places Gen X at 1965–1980 and Millennials at 1981–1996, while its older framework defined the Greatest Generation as those born before 1928 and the Silent Generation as 1928–1945.
McCrindle uses a different 15-year framework for several cohorts: Gen X 1965–1979, Gen Y 1980–1994, Gen Z 1995–2009, Gen Alpha 2010–2024, and Gen Beta 2025–2039.
So if your birth year appears to fall into two different generations depending on the source, that does not necessarily mean one source is wrong.
The Greatest Generation and Silent Generation
Greatest Generation: 1927 and Earlier
The Greatest Generation generally refers to Americans born before 1928. Many members grew up during the Great Depression and came of age during World War II. The name became especially popular through Tom Brokaw’s 1998 book The Greatest Generation. Pew Research Center describes this group as the generation that came of age during the Depression and World War II and notes that its population has become very small.
Common experiences associated with this generation include:
- The Great Depression
- World War II
- Rationing and economic hardship
- The growth of radio
- Early mass automobile ownership
- Postwar economic expansion
- Traditional community structures
- Strong emphasis on duty and sacrifice
The label should not be treated as a personality test. People born during this period had very different lives depending on country, class, race, gender, and family circumstances.
Silent Generation: 1928–1945
The Silent Generation follows the Greatest Generation. Pew Research Center defines it as people born from 1928 through 1945.
Members of this generation were children during the Great Depression and World War II and entered adulthood during the postwar period. Their formative years included major changes in television, consumer culture, employment, and family life.
The name “Silent” came from the idea that this generation was comparatively conformist and less publicly outspoken during its early adulthood. Time magazine helped popularize the term in 1951.
For someone researching family history, historical demographics, or workplace generations, the Silent Generation is particularly useful because it sits between the wartime generation and the much larger Baby Boom cohort.
Baby Boomers and Generation X
Baby Boomers: 1946–1964
Baby Boomers were born during the large increase in U.S. births following World War II. Pew Research Center consistently uses 1946–1964 as the U.S. Baby Boom generation.
Their formative period included enormous social and economic changes, including:
- Postwar prosperity
- The expansion of television
- The civil rights movement
- The Cold War
- The Vietnam War
- The space race
- Rock and roll
- The rise of mass suburbanization
- Major changes in higher education
- Expanding consumer culture
The Baby Boomer label is especially common in American business, politics, media, and demographic research.
However, not every person born between 1946 and 1964 shares the same worldview. A person born in 1946 and someone born in 1964 experienced very different childhoods, technologies, and cultural events.
Generation X: 1965–1980
Generation X, often shortened to Gen X, is commonly defined by Pew Research Center as people born from 1965 through 1980.
Gen X grew up during the transition from an overwhelmingly analog world toward personal computing and digital technology.
Major influences included:
- Cable television
- MTV and music-video culture
- Video games
- Personal computers
- The end of the Cold War
- Economic changes of the 1970s and 1980s
- The rise of dual-income households
- The early internet
- Changing family structures
The generation is sometimes described as a bridge between older analog generations and younger digital generations.
That description can be useful, but it should not become a stereotype. Generational labels describe broad cohorts, not identical personalities.
Millennials and Generation Z
Millennials: 1981–1996
Millennials, also known as Generation Y, are commonly defined by Pew Research Center as people born from 1981 through 1996.
The name “Millennial” comes from the fact that this generation began entering adulthood around the turn of the millennium.
Millennials experienced the rapid expansion of:
- The internet
- Search engines
- Mobile phones
- Social media
- Online shopping
- Digital entertainment
- Smartphones
- Remote communication
Their early adulthood was also shaped by major economic events, especially the Great Recession.
One useful way to understand Millennials is to remember that they are a transitional generation. Older Millennials may remember life before widespread home internet, while younger Millennials experienced the internet much earlier.
That is why two people born within the same broad generation can have very different relationships with technology.
Generation Z: Commonly 1997–2009
Generation Z, or Gen Z, follows the Millennial generation. Its exact beginning and ending years vary among researchers.
A practical framework places Gen Z after the 1981–1996 Millennial range and before Generation Alpha. Pew Research Center, for example, has used 1997 onward for Gen Z in its research.
Gen Z’s formative years are strongly associated with:
- Smartphones
- Social media
- Streaming video
- Short-form digital content
- Always-connected communication
- Online communities
- Creator culture
- Rapid technological change
- The COVID-19 pandemic during adolescence or early adulthood for many members
Gen Z is often called a digital-native generation, but that phrase can oversimplify things. Digital access, family income, geography, education, and culture all affect how someone experiences technology.
Generation Alpha and Generation Beta
Generation Alpha: 2010–2024
Generation Alpha is one of the newest widely used generational labels. McCrindle defines it as people born from 2010 through 2024.
The name Alpha marks a shift from the Latin-letter sequence of Gen X, Gen Y, and Gen Z to the Greek alphabet. McCrindle describes Alpha as the first generation born entirely in the 21st century and links its early years to the rise of smartphones, tablets, social platforms, globalization, and highly connected digital environments.
Generation Alpha’s childhood has been influenced by:
- Tablets and smartphones
- Touchscreen technology
- YouTube and streaming
- Artificial intelligence
- Digital classrooms
- Online gaming
- Social platforms
- Connected toys and devices
- The COVID-19 pandemic
- Growing awareness of climate and global issues
Because many members of Gen Alpha are still children, claims about their final adult characteristics should be treated carefully. We can describe their environment, but it is too early to know exactly how the generation will develop.
Generation Beta: 2025–2039
Generation Beta is the generation that follows Generation Alpha. McCrindle defines Gen Beta as people born between 2025 and 2039.
This is an emerging cohort, so statements about Gen Beta are necessarily predictions rather than established demographic findings.
McCrindle expects Gen Beta to grow up with artificial intelligence and highly integrated digital technology as normal parts of daily life. Its framework also anticipates that many Gen Beta children will be raised by Millennials and older members of Gen Z.
Potential influences include:
- Artificial intelligence
- Personalized education
- Generative technology
- Automation
- Connected homes
- Climate and sustainability concerns
- Global digital communities
- New approaches to work and education
It is important not to describe Gen Beta as though its personality is already known. Most of its members have only recently been born, so researchers will need decades of evidence before making strong conclusions about the cohort.
Why Generation Years Are Different From One Source to Another
One of the biggest mistakes people make when searching for generation names and years is assuming there is one official worldwide chart.
There isn’t.
Generations are cultural and demographic categories. Researchers choose boundaries based on factors such as birth rates, historical events, technology, social change, and the experiences of people coming of age at similar times. Pew Research Center explicitly notes that generational boundaries are useful analytical tools but should not be viewed as rigid divisions.
For example, Pew uses:
- Gen X: 1965–1980
- Millennials: 1981–1996
McCrindle uses:
- Gen X: 1965–1979
- Gen Y: 1980–1994
- Gen Z: 1995–2009
- Gen Alpha: 2010–2024
- Gen Beta: 2025–2039
These differences matter when you are writing an article, conducting demographic research, building a marketing campaign, or comparing survey results.
Why the boundaries move
Generational boundaries can change because:
- Researchers use different methodologies.
- Different countries experience events at different times.
- A generation may take years to develop a widely accepted name.
- Historical events can create meaningful dividing points.
- Some researchers favor 15-year cohorts while others use different spans.
- New generations such as Gen Alpha and Gen Beta are still being studied.
If someone was born near a boundary, it is perfectly reasonable to see more than one classification depending on the source.
How to Find Your Generation by Birth Year
The easiest approach is to start with your birth year and compare it with the framework being used.
For example:
- Born in 1955? You are generally a Baby Boomer.
- Born in 1975? You are generally Gen X.
- Born in 1988? You are generally a Millennial.
- Born in 2002? You are generally Gen Z.
- Born in 2015? Under the McCrindle framework, you are Gen Alpha.
- Born in 2027? Under the McCrindle framework, you are Gen Beta.
The tricky cases are people born close to a generational cutoff.
Suppose someone was born in 1995. One framework may place that person in Gen Z, while another may place them in a late Millennial or Gen Y cohort. That does not mean the person’s identity is wrong. It simply shows why generation labels should be treated as flexible analytical categories.
For personal use, the best approach is to state the framework when the distinction matters.
For example, instead of saying:
“People born in 2010 are definitely Gen Alpha.”
A more accurate statement is:
“Under McCrindle’s framework, people born in 2010 are part of Generation Alpha.”
That small distinction makes demographic content more trustworthy.
Common Generation Stereotypes and Mistakes to Avoid
Generational labels can be useful, but they can also create misleading assumptions.
Mistake 1: Treating generations as personality types
Being born in a particular year does not automatically make someone hardworking, rebellious, traditional, tech-savvy, sensitive, wealthy, or politically minded.
Mistake 2: Assuming everyone in a generation had the same childhood
A child growing up in rural America may have had a very different experience from someone growing up in New York City. The same is true when comparing people across countries.
Mistake 3: Ignoring socioeconomic differences
Access to education, healthcare, technology, housing, and employment can shape a person’s experience as much as their birth year.
Mistake 4: Applying U.S. labels globally
Terms such as Baby Boomer, Gen X, and Millennial are widely recognized around the world, but their cultural meaning can differ significantly outside the United States.
Mistake 5: Treating generation boundaries as official laws
There is no universal authority that assigns every person to one generation based solely on their birthday. Researchers use different definitions for different purposes.
Mistake 6: Making predictions about very young generations as facts
Gen Alpha and Gen Beta are still developing. It is reasonable to discuss the technology and environment surrounding them, but long-term claims about their adult behavior remain uncertain.
Frequently Asked Questions About Generation Names and Years
What are the generation names in order?
The commonly recognized sequence is the Greatest Generation, Silent Generation, Baby Boomers, Generation X, Millennials or Generation Y, Generation Z, Generation Alpha, and Generation Beta. The exact birth years can vary by researcher, especially for Gen Z and newer cohorts.
What generation am I if I was born in 1990?
If you were born in 1990, you are generally considered a Millennial. Pew Research Center commonly defines Millennials as people born from 1981 through 1996.
What generation is someone born in 2000?
Someone born in 2000 is generally considered Generation Z. However, generational boundaries vary between sources, so it is best to identify the specific framework when precision matters.
What generation is 2010?
Under McCrindle’s framework, someone born in 2010 belongs to Generation Alpha, which covers births from 2010 through 2024.
What generation is a person born in 2025?
Under McCrindle’s framework, a person born in 2025 is part of Generation Beta. McCrindle defines Generation Beta as 2025–2039.
Why are Millennials also called Gen Y?
Millennials are sometimes called Generation Y because they followed Generation X. The term “Millennial” became more widely used because this generation came of age around the beginning of the new millennium. Researchers do not always use exactly the same boundaries for Gen Y and Millennials.
Is there an official list of generation years?
There is no single worldwide official list that every researcher follows. Pew Research Center notes that generational boundaries are useful guidelines rather than hard-and-fast divisions. Different researchers may therefore use different birth years.
What comes after Generation Beta?
McCrindle’s proposed sequence places Generation Gamma after Generation Beta, followed by Generation Delta. Under that framework, Gamma would cover 2040–2054 and Delta 2055–2069. These are future projections, not established generations with completed research.
Final Takeaway: Generation Names Are Useful, but Birth Years Are Only the Starting Point
Knowing the generation names and years is a useful way to understand broad age groups and the historical periods that shaped them.
From the Greatest Generation and Silent Generation to Baby Boomers, Gen X, Millennials, Gen Z, Gen Alpha, and the emerging Gen Beta, each cohort grew up under different social, economic, and technological conditions.
Still, a birth year does not tell the whole story.
Generational boundaries differ between researchers, and cultural experiences vary by country, family, community, income, education, and major life events.
Pew Research Center treats generations as useful analytical groupings rather than strict categories, while newer frameworks such as McCrindle’s introduce specific ranges for Gen Alpha and Gen Beta.
