People born in different decades are classified as Baby Boomers, Generation X, Millennials, Generation Z or Generation Alpha. These labels broadly reflect the social, economic, cultural and technological environments in which they grew up.
Each generation has defining experiences, although its commonly attributed characteristics are generalizations, not rules that apply to everyone. Birth-year boundaries also vary slightly across researchers.
Here is a look at the major generations in chronological order.
The generations and their birth years
| Generation | Approximate birth years |
| Greatest Generation | 1901–1927 |
| Silent Generation | 1928–1945 |
| Baby Boomers | 1946–1964 |
| Generation X | 1965–1980 |
| Millennials (Generation Y) | 1981–1996 |
| Generation Z | 1997–2012 |
| Generation Alpha | 2013–2024 |
| Generation Beta | 2025–2039 (projected) |
Note: These are commonly used reference ranges, not universally accepted cut-offs. Generation Alpha is sometimes dated from 2010, depending on the classification.
1. The Greatest Generation (1901–1927)
Also called the G.I. Generation, this group grew up during the Great Depression and experienced the Second World War. Many served in the war or contributed on the home front. They are often associated with resilience, sacrifice and a strong sense of duty.
2. The Silent Generation (1928–1945)
Growing up during the aftermath of the Great Depression and the Second World War, this generation is associated with discipline, frugality and traditional values. Its members witnessed the beginnings of television, post-war reconstruction and significant social change.
3. Baby Boomers (1946–1964)
The name refers to the sharp rise in births following the Second World War. Baby Boomers grew up during economic expansion, the spread of television and major cultural and political movements. They also witnessed the beginnings of the space age.
4. Generation X (1965–1980)
Often called Gen X, this generation grew up during the transition from an analogue to a digital world, witnessing the rise of personal computers, cable television and video games. The term was popularized by Douglas Coupland’s 1991 book Generation X.
5. Millennials or Generation Y (1981–1996)
Named for coming of age around the turn of the millennium, Millennials experienced the transition from landlines and physical media to the internet, mobile phones and social media. They witnessed the expansion of the digital economy.
6. Generation Z (1997–2012)
Also known as Zoomers, Gen Z grew up with smartphones, social media and instant connectivity. Unlike Millennials, many have little or no memory of a world without the internet. Digital technology has been an integral part of their childhood.
7. Generation Alpha (2013–2024)
This generation is growing up with tablets, artificial intelligence, voice assistants and personalized digital experiences. Technology has been part of their lives from an early age, making their childhood markedly different from that of previous generations.
8. Generation Beta (2025–2039)
The newest generational label, Generation Beta refers to children born from 2025 onwards, under a classification proposed by Australian researcher Mark McCrindle. They are expected to grow up in a world increasingly shaped by artificial intelligence, automation and advanced technologies.
Why remember these labels?
Generational labels help us understand how historical events, cultural shifts and technological developments shape people growing up in different periods. However, they should not be treated as fixed personality types. Geography, family background, education and economic circumstances also influence people’s attitudes and experiences.
From the Greatest Generation that lived through the World Wars to Generation Beta growing up in the age of artificial intelligence, these labels offer an interesting perspective on how society evolves.
