Generation years chart outlines the seven recent demographic cohorts stretching way back to the 20th Century. These generations are shaped by similar characteristics in parenting, culture, technology and social trends.

Tech only became a point of reference starting with the Millennial generation. It is now the core point of reference for Generation Z and Alpha cohorts.

The timeline starts with the generation which lived at the start of the 20th Century and ends with the current generation, which is born at the beginning of the 21st century. The birth years of the generations vary and span between 15 to 20 block years.

The United States, Europe and the rest of the developed world have documented generation statistics for many decades. Developing countries only become part of the wave as a result of tech and globalization.

The Greatest Generation

The Greatest Generation was the first to be documented at the start of the 20th Century. It brings together a demographic cohort born between 1901 and 1924 generation years.

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 perseverance during the 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’.

The Silent Generation

This cohort was born between 1925 and 1945. The products of this generation years said little and preferred to work.

This was attributed to firm parenting, which was a popular parenting style around this 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 It was branded unimaginative, cautious and withdrawn.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.

The Baby Boomer Generation

The Baby Boomer generation years fall 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. The people contributed intensely to driving the US and other economies in the Western world.

Apart from bumper birth, other notable events happened during this generation years. Foremost was the Vietnam War and the enaction of the Civil Rights Act of 1964.

Generation Z

The generation years of this group stretches from 1996 to 2009. The Z or iGen, just like the previous generation Y, has immersed itself in the world of internet and technology.  The iGeners were born right inside it and know nothing out of the tech box.

They also approach life passively in comparison to Millennials. For example, they learn to drive late and become sexually active much later in life. They also drink alcohol a little later than the previous generations.

This trait has led experts to liken them to the Silent generation cohort whose birth dates happened between 1925 and 1945.

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 have little or no time for serious concentration at work and school.

Generation Alpha

Generation Alpha is the latest in the generation years chart and one that best fits the digital nativedescription. It brings together people born between 2010 and 2025.

It comes after generation Z. As of 2018, the eldest Alpha kid is 8.

Alphas will probably be the most transformative generation ever. This is perhaps because they are born in a world experiencing 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 by 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 it into the life of Alphas. Tablets have become a popular tool for collaborative learning, especially in the developed world.

Alpha kids are so much immersed into touchscreen devices that they hardly understand the corded and touchless phones. But this is about to change.

The sheer speed of advancement in artificial intelligence means that typing on a small screen will seem old-school very soon. The alpha adults will probably never use apps and cell phones the way it is done today.
