What defines a generation? (2024)

As many millennials are stepping into parenthood, earning the nickname “parennials”, the conversation around generational labels has become more widespread than ever.

What do these labels truly signify, and how are the boundaries of each generation defined? The year you were born determines what generation you’re within, but the timelines for each generation aren’t set in stone.

Understanding these labels can provide valuable insights into societal trends and cross-generational dynamics.

Here’s a comprehensive guide to the generations dating back to 1900, highlighting the key events that shaped each group and their typical characteristics.

Understanding the different generations

Generations are typically defined as groups of people born within a specific time frame, usually around 20 years. Deborah Carr, PhD, a sociology professor at Boston University, said: “Generations take on special meaning because their members tend to experience critical life events and transitions at particular historical moments, and these moments define their lives.”

Although experts may debate the exact timelines, the following guide provides a widely accepted overview of the generations:

The Greatest Generation (GI Generation): Born 1901–1927

The Silent Generation: Born 1928–1945

Baby Boomer Generation: Born 1946–1964

Generation X: Born 1965–1980

Millennial Generation (Generation Y): Born 1981–1996

Generation Z (iGen): Born 1997–2010

Generation Alpha: Born 2010–2024

The Greatest Generation (1901–1927)

The Greatest Generation, also known as the GI Generation, lived through the hardships of the Great Depression and fought in World War II. This generation is credited with popularising jazz and swing music, and their experiences fostered a culture that valued hard work, resilience and family.

The Silent Generation (1928–1945)

The Silent Generation earned its name for its tendency to conform and remain quiet during the McCarthy era, a time marked by the fear of communism. This generation was characterised by a strong work ethic and a focus on earning one’s way through life.

Baby Boomers (1946–1964)

Baby Boomers experienced a population boom following World War II. Despite their conservative reputation today, Boomers were at the forefront of cultural shifts, such as protesting the Vietnam War and participating in the movement “Summer of Love.”

The movement was characterised by a rejection of mainstream values and an embrace of alternative lifestyles, including communal living, free love, and experimentation with psychedelic drugs. Music, particularly the rise of rock bands like The Beatles, played a key role in shaping the cultural atmosphere. This generation also redefined parenting by prioritising their children’s perspectives and establishing family meetings as a norm.

Generation X (1965–1980)

Generation X is frequently labelled as the “slacker” generation, but their experiences tell a different story. Growing up during the AIDS epidemic and the rise of LGBTQ+ rights, Gen X witnessed significant cultural and social changes. As parents, Gen Xers were known for their helicopter parenting style, staying deeply involved in their children’s lives – a stark contrast to the more hands-off approach of their Boomer parents.

Millennials (1981–1996)

Millennials, or Generation Y, have lived through transformative events like 9/11 and the rise of the internet. This generation straddles a unique position, having experienced life both before and after the digital revolution. Known for their environmental consciousness and community orientation, Millennials are also reshaping parenting norms by encouraging authenticity and supporting gender non-conformity in their children.

Generation Z (1997–2010)

Generation Z is the first to grow up in a world of constant digital connectivity. This tech-savvy generation is marked by its environmental awareness, inclusivity and political engagement – despite many not yet being of voting age. Like Millennials, Gen Z is pushing for a more inclusive and connected world.

Generation Alpha (2010–2024)

Generation Alpha, the newest unit, is growing up in an era dominated by social media and advanced technology. While it’s too early to fully define Generation Alpha, the impact of events like the COVID-19 pandemic will undoubtedly shape their worldview and values.

The importance of understanding generational differences

As we move further into the 21st century, the lines between generations may blur, but understanding these distinctions remains crucial. Generational analysis helps explain trends in everything from politics to parenting, offering insights into how past experiences shape present behaviours and future expectations.

Of course, social media has humoured the way we see different generations with many parodies depicting different generations within everyday situations. A popular Instagram account (champagnecruz) often portrays different generations at work. Speaking of work, the rising trend of digital nomadism is made of 50% millennials and Gen Zs.

Whether you’re interacting with colleagues, raising children, or simply navigating social norms, being aware of generational influences can enhance your experience and build greater connections with those around you.
