Generation Years Chart | 20th to 21st Century Generations
The generation years chart and timeline describe the seven recent demographic cohorts stretching way back to the 20th Century. The generations are categorized in such a way they bring together people born in the same block years, and share characteristics in parenting, culture, health, social/economic well-being, and technology.
Technology only became a point of reference starting with the Millennial generation. It is the core point of reference today with the younger generations Z and Alpha.
The block years for the different generations have always fluctuated between 13 to 23 years, in no particular order. The timeline starts with the Greatest Generation, born early in the 20th Century and culminates with the Alpha cohort, born entirely in the 21st Century.
The United States, Europe, and the rest of the developed world have documented demographic cohorts for many decades. Developing countries only become part of the wave due to globalization and the expansive world of technology.
Generation Years Chart
The following chart shows the birth years and ages of the different generations as of 2020. It is important to note that the start and end of generation birth years are only an educated approximation and not definite for the different generations. You simply cannot place the birth years of a generation with utmost authority. The beginning and end of generation years are actually transitional in a sense as explained by historical, behavioral, cultural, and geographical reasons.
The block–years column sums up the total number of years between the 1st to the last birth for each generation.

Generation Years Timeline
Below are the descriptions of the 7 recent generation cohorts and their related birth years. As explained above these years are not definite but relative to historical events and geographical zones.
1. The Greatest Generation : (1901- 1924)
The Greatest Generation cohort is the first in the chart of generations to be documented at the start of the 20th Century. It brought together a demographic group of people born between 1901 and 1924.
Tom Brokaw coined the name for this group, a title that became popular after he published a book he called The Greatest Generation. Those born during this period went through World War I (1914) and World War II (1940), and the Great Depression of 1927-1939. They were considered great because they showed remarkable determination and resilience during the two wars and the Great Depression. They had a passion and willingness to fight for their country because they believed it was the right thing to do.
Ronald Reagan (1911) and John F Kennedy (1917) are two famous personalities born during the Greatest generation years.
2. The Silent Generation : (1925 – 1945)
This generation was born between 1925 and 1945, just after WWI and through WWII. The products of the Silent Generation years said very little and preferred to work. This was attributed to the firm parenting style which was popular around that time. They were nurtured to be seen rather than heard. It is no wonder they were loyal to their masters.
The name Silent Generation was coined by Time Magazine, in a 1951 article titled The Younger Generation. The article slammed this group for lacking ambition and drive. It was branded unimaginative, cautious and withdrawn. The Great Depression which lasted from 1929 to 1939 and the Dust Bowl, which devastated farmlands in the 30s perhaps contributed to their conditions.
Warren Buffet (1930), Malcolm X (1925), Marilyn Monroe (1926), Harry Belafonte (1927), and Mohammed Ali (1941), are some of the famous personalities born during this generation years.
3. The Baby Boomer Generation : (1946 – 1964)
The Baby Boomer generation years fell between 1946 and 1964, in a period full of hope in the US, in particular. The post-war years allowed people to do what they had not during the war. A sense of peace and prosperity reigned which led to young marriages and increased birthrate.
This lasted for around 20 years. The bumper birth rate created a new era of consumerism as a result of the large population. This helped drive the US economy and gave birth to a new wave of rich individuals.
Apart from bumper births, other notable events such as the Vietnam War and the enaction of the Civil Rights Act of 1964 happened during these years.
In the US alone, African-Americans make up 10 percent and Hispanics 8 percent of this demographic group. In total, Baby Boomers will make up 20 percent of the American population by 2030.
Popular personalities in this generation years are George Bush (1946), Steve Jobs (1955), Tony Blair (1953), Princess Diana (1961), Jeff Bezos (1964), Nicholas Cage (1964), Johnny Depp (63), Bill Clinton (1946), Barack Obama (1961), Donald Trump (1946), Bill Gates (1955) and George Clooney (1961).
4. Generation X : (1965 – 1979)
Also called Baby Buster generation, the X Generation reversed the baby boom trend which was the hallmark of the previous Baby Boomer generation, by registering a reduced birthrate.
The generation also groomed an increasing number of single-parent homes and continue to record higher divorce numbers than the previous generations, even to the 21st Century. They are independent-minded, informal, casual, and entrepreneurial, and are passing on the traits to their children of the Z cohort.
Following the innovation and distribution of the first lots of microcomputers in the 80s and 90s, Generation X became one of the first to interact with technology. Computers were, however, enormous, and only installed in government and research installations.
The photographer Robert Capa popularised the term Generation X which loosely meant ‘unknown’. The X generation desired, and even today, prefer not to be defined in any manner.
Baby busters love TV and for this, grew up watching Friends and a host of other popular soaps on Television.
Famous personalities from this generation years: Jay Z (1969), Tiger Woods (1975), Halle Berry (1966), Julia Roberts (1967), Celine Dione (1968), and Will Smith (1968).
5. Generation Y : (1980 – 1995)
Also called Millennials, the Generation Y cohort was born between 1981 and 1995, during the years that technology was taking initial shape, for productivity. The use of the internet as a means of innovation and communication was also picking steam, just as the 20th Century was coming to a close.
This correlation with the initial years of digital evolution explains why millennials use technology to extend their reach and to venture into global markets. They have used these to drive and shape economies around the world, and continue doing so.
Millennials have grown up in a time of rapid change, giving them a set of priorities and expectations sharply different from previous generations.Who are they?
Technology remains critical for driving productivity and has become the tool of choice even at home.
A large chunk of millennial parents is also renowned for championing a new age of parenting, unlike the Boomers and Xers. They are more than likely to entertain their children donning wearable gadgets and trying out different forms of AI innovations.
And in a 2018 survey carried out by Go Daddy, 48% of millennial parents deemed it fine for their Alpha children to have an online experience as compared to only 27% of Gen Xers.
Popular figures from this era: Mark Zuckerberg (1984), Taylor Swift (1989), Christina Aguilera (1980), Nicki Minaj (1982), Rihanna (1988) and Beyoncé (1981).
6. Generation Z : (1996 – 2009)
The Generation Z years stretch between 1996 and 2009. The Zs are also known as the children of Generation X and are in school up to university during the birth years of Generation Alpha. As of 2025, when the last Alpha will be born, they will make up close to 27 percent of the workforce, according to McCrindle. The Z or iGen, just like the previous generation Y, has immersed itself deep in the world of internet and technology. But unlike their predecessors, they exhibit a sense of euphoria, hoping and determined to avoid past mistakes by earlier generations.
They also approach fancy lifestyles rather passively in comparison to Millennials. For example, they learn to drive late and become sexually active much later in life, they also indulge in alcoholic beverages a little later than the previous generations. These traits have led experts to somehow liken them to the Silent generation of the 1920s to 1940s.
Instead, they spend most of the time planning for their future amidst the tight work conditions around the world.
The huge amount of information at their disposal has also affected their sense of concentration. Hence, they are always multi-tasking and have developed short attention spans. They may seem not to have time for serious stuff at school and at work, but experts presume they are very much goal-oriented and pragmatic.
Popular iGeners: Baby Ariel (2000), Zendaya (1996), and Baby Kaely (2004).
7. Generation Alpha : (2010 – 2025)
Generation Alpha is the latest in the chart of generation years and one that best suits the digital native description. The Alpha cohort brings together people born between 2010 and 2025, a generation born entirely in the 21st Century. The Alpha cohort replaced Generation Z, whose birth years fell between 1996 and 2009. The youngest Z kids were thus born in the first 9 years of the 21st Century.
As of 2020, the eldest Alpha child is 10 years old.
Alphas will probably be the most transformative generation ever. This is perhaps because they are born inside a world saturated with tech gadgets and are experiencing first-hand the most transformative trends in technology. It is estimated that over 2.5 million Alpha kids are delivered weekly in health facilities around the world, and their numbers will reach a whopping 2 billion as of 2025.
The first alpha kids were born in 2010, the same year the first iPad was released. The iPad kickstarted a tablet war between manufacturers, which has catapulted tablets into the life of Alphas. They are popular tools for collaborative learning, especially in the developed world.
Alpha kids are so much immersed in touchscreen devices that they hardly understand the corded and touchless phones. Their interaction with technology is however changing.
The sheer speed of advancement in artificial intelligence means that typing on a small screen is becoming old-school for them The Alpha adults will probably never use apps and cell phones the way they are used today.
