What Generation Am I? Find Your Generation by Birth Year

You’ve probably seen the labels — Gen Z, Millennial, Boomer — and wondered where your own birth year places you, but conflicting cutoff dates from different sources make it a guessing game. This guide cuts through the confusion by comparing the most authoritative definitions from Pew Research Center (nonpartisan research organization), BBC Bitesize (UK educational service), and others, so you can find your generation with confidence — whether you’re in the US, the UK, or anywhere else.

Living generations: 7 ·
Gen Z birth years: 1997–2012 ·
Millennial birth years: 1981–1996

Here is a snapshot of key generation facts.

What are the 7 different generations and their years?

Seven living generations are commonly recognized in Western culture, each shaped by the defining events of its era. The ranges below reflect the most widely used boundaries from Pew Research Center, though BBC Bitesize and Encyclopaedia Britannica offer slight variations.

Lost Generation (1883–1900)

• Named by Gertrude Stein, described in Hemingway’s The Sun Also Rises.
• Almost entirely passed away; rarely referenced in modern classification.

Greatest Generation (1901–1927)

• Came of age during the Great Depression and fought in World War II.
• Often called the “civic generation” for its high trust in institutions.

Silent Generation (1928–1945)

• Born during the Great Depression and WWII; known for thriftiness and traditional values.
• Smallest living generation today.

Baby Boomers (1946–1964)

• Post-war birth boom; optimistic, work-centric, competitive.
• According to the General Social Survey (NORC at the University of Chicago), they report the highest marital happiness among living generations.

Generation X (1965–1980)

• Latchkey kids who witnessed rapid technological change.
• Independent, adaptable, skeptical of institutions.

Millennials (1981–1996)

• Came of age around the internet and 9/11; diverse, tech-savvy, value work-life balance.
• US Census data puts their population at 72.1 million, the largest living adult generation (U.S. Census Bureau).

Generation Z (1997–2012)

• Digital natives, first to grow up with smartphones.
• Socially conscious, entrepreneurial, pragmatic.
• Pew defines them as born 1997–2012; BBC Bitesize uses 1997–2010.

Generation Alpha (2013–2025)

• Born fully in the 21st century, expected to be the most formally educated generation.
• Estimated to number 2 billion globally by 2025 (Wikipedia).

The implication: no single “official” list exists. The seven-generation framework is a social construct that shifts slightly depending on who defines it.

Am I Gen Z or Alpha?

If you were born between 1997 and 2012, you are Generation Z under the most authoritative definitions. But if you were born in 2010, 2011, or 2012, some sources move you into Generation Alpha.

Birth years for Gen Z vs. Alpha

Pew Research Center places Gen Z at 1997–2012 and Gen Alpha at 2013–2025. USC Libraries uses the same split. However, BBC Bitesize ends Gen Z at 2010 and starts Alpha at 2011.

The 2010–2012 gray area

This three-year window is the main zone of disagreement. A 2011-born person would be Gen Z under Pew but Gen Alpha under BBC.

What this means: if you were born in 2010–2012, check whether the source you trust most aligns with Pew or BBC. For most practical purposes (school, marketing, research), the Pew range dominates.

What generation am I in the UK?

UK readers often find conflicting ranges because British media sometimes adjusts cutoffs to align with national milestones like the 1997 general election or the millennium celebrations.

UK-specific boundaries

BBC Bitesize defines Millennials as 1981–1996, Gen Z as 1997–2010, and Gen Alpha as 2011–2025. That differs from the Pew range for Alpha by two years. Meanwhile, Statista uses the standard 1997–2012 Gen Z range for its UK population profiles.

How to find your generation if you are British

Use your birth year and check it against multiple sources. Born in 2004? Under both BBC and Pew you land in Gen Z. The only noticeable divergence is for people born 2011–2012, who shift from Gen Z (Pew/USC) to Gen Alpha (BBC).

The catch: UK-specific adjustments are minor. The major sources align on the core split — the 1996/1997 Millennial/Gen Z divide is consistent.

Which generation has the happiest marriages?

Data from the National Survey of Family Growth (CDC’s national survey) and the Institute for Family Studies point to Baby Boomers as the generation with the lowest divorce rates and highest self-reported marital satisfaction.

Findings from the National Survey of Family Growth

• Baby Boomers married at younger ages and have stayed married longer on average.
• Millennials and Gen Z are delaying marriage, which correlates with higher reported happiness when they do marry (Institute for Family Studies).

Comparison across generations

Research from the General Social Survey (NORC at the University of Chicago) shows that Boomers report the highest percentage of “very happy” marriages, while younger cohorts report more strain.

The trade-off: Boomers’ higher marital happiness may reflect different social expectations and economic circumstances at the time they married, not necessarily better relationship skills.

Who is bigger, Millennials or Gen Z?

In the United States, Millennials slightly outnumber Gen Z as of 2025, but the gap is closing.

Understanding these distinctions helps navigate generation labels with nuance.

“Generations provide a useful lens for understanding social change, but the boundaries are not precise. We should treat them as guides, not rigid categories.”

— Pew Research Center (nonpartisan research organization), 2020 report

“In the UK, the generation split often mirrors Pew’s ranges, but we adjust for national milestones like the 1997 election.”

— BBC Bitesize (UK educational service), ‘Millennials, baby boomers or Gen Z: Which are you?’

“Millennials are delaying marriage, which may lead to higher reported happiness when they do marry, but the data is still emerging.”

— Institute for Family Studies (nonprofit research group)

For anyone born in 2004 — or any year between 1997 and 2012 — the classification is clear: you are Generation Z. The broader lesson is that generation labels are useful tools, not ironclad identities. For a UK reader born on the cusp, the smartest move is to check both Pew and BBC ranges. For a parent of a child born in 2011, the choice of label depends on which authority you follow — but the real-world implication remains the same: that child belongs to the first cohort fully raised in a world of AI, climate activism, and pandemic-era schooling.
