The Lost Generation / The Generation of 1914

The Lost Generation is the age that grew up during World War I. Lost additionally represents Directionless, Wandering, Disoriented. This implies in those days, there was a great deal of aimlessness and disarray between the overcomers of the war in the principal couple of years. The term Lost is additionally used to allude to the specialists of the time, and explicitly American ostracized writers which were living in Paris during the 1920s.

Gertrude Stein is credited with authoring the term. It was later that got more popular when Ernest Hemingway used it in the epigraph for his 1926 novel The Sun Also Rises: "You are all a lost generation".

The Lost Generation is the group of people who were born somewhere in the range of 1890 and 1915, and numerous researchers utilize the term in reference to the 1920s. Since the death of Nabi Tajima (4 August 1900 – 21 April 2018), it is believed that there is no one left from The Lost Generation.

The Interbellum Generation

The Interbellum Generation is a term derived from the Latin inter "between" and bellum "war". Those who were born during this period of time were too young to be participating in the military during World War I and also The interbellum generation was generally too old to serve as enlisted personnel in World War II. Although, a part of this group of people could also be found in the armed forces during the latter conflict. Most of their children are part of the Silent Generation.

Those who were born during this generation came of age either during the “Roaring Twenties” or the starting stage of the “Great Depression”, preceding the election of Franklin D. Roosevelt and the declaration of the “New Deal”.

The four Presidents of the US of the Interbellum Generation were Lyndon B. Johnson (born in 1908), Reagan (born in 1911) and Richard M. Nixon and Ford (both born in 1913).

The Greatest Generation

The people of The Greatest Generation grew up during the Great Depression and fought in World War II. The term “Greatest Generation” got very popular when the NBC Nightly News anchor and author Tom Brokaw mentioned it in his book titled by the same name. The Greatest Generation grew up during World War II.

The youngest persons to be part of The Greatest Generation, are well into their 90s as of 2019. According to the U.S. Department of Veterans Affairs, as of 2016, there were only 620,000 veterans left out of the 16 million who were part of World War II. The number of The Greatest Generation veterans who lose their life each day is 372.

The major part of The Greatest Generation are the children of The Lost Generation (those who grew up during World War I) and they are the parents of the Baby Boomer Generation. Then later on, they preceded the well known Silent Generation, a generation born between 1925 - 1945. Generation X, Generation Y and the Millennials are the grandchildren of the members who are part of The Greatest Generation.

The Silent Generation

The Silent Generation is the generation following The Greatest Generation and preceding the Baby Boomer Generation. This Generation includes most of those who fought in the Korean War. The Silent Generation years range is defined as individuals born between 1925 - 1945.

The term Silent Generation was initially applied to the United States and Canada people and later followed by Australia, New Zealand, South America, Western Europe. In the U.S., because of the financial insecurity of the 1930s, the generation was small. Also, the war of the early 1940s caused a decrease in births. The people who are part of this Generation are well known as creating the leadership of the Civil Rights Movement, also for comprising the Silent Majority.

The Great Depression was a period of time which The Silent Generation was part of and as so, now they had a hard time economically speaking and providing their families wasn't easy. They went through some hard times too when they were children while World War II was happening. Many of this generation have lost their fathers or older siblings while in war. They saw Nazism falling and the tremendous power of the Nuclear Bomb.

Baby Boomer Generation

76 million Americans were born during the Baby Boomer Generation time frame. Because of this fact, this generation was described as a “Shockwave”. The term Baby Boomer itself refers to a well noticeable increase in the birth rate. This increase in particular, was described as a “Boom” by many newspapers. The first time this term was used, was recorded in January 1963 in a Daily Press article.

This is how the time frame of this generation is represented in different places:

    • Pew Research Center: 1946 - 1964
    • United States Census Bureau: mid-1946 and mid-1964
    • Federal Reserve Board: 1946 - 1964
    • Australian Bureau of Statistics: 1946 - 1964
    • Australian’s Social Research Center: 1946 - 1964

In the United State, The Baby Boomer generation can be divided in two parts. One of them being the “Leading-Edge Baby Boomers”, born between 1946 - 1955 in which part of this time frame are roughly 38,002,00 people of all races. Meanwhile the other half, called “Late Boomers” or “Trailing-Edge Boomers”, born between 1956 - 1964 where 37,818,000 individuals are part of, according to Live Births by Age and Mother Race, 1933 - 1988 published by the Centers for Disease Control’s National Center for Health Statistics.

Generation X

Generation X is the generation following The Baby Boomer Generation and preceding the Millennials. There are different time frames which different sources use. Researchers and some popular media usually use the time frame between 1965 - 1979 in order to define this generation. On the other hand, other sources use time frames starting as early as 1960 and ending in some point between 1977 to 198.

This generation is the demographic history following the post- World War II Baby Boom, defining a change in the Generation from the one of The Baby Boomers. The oldest person being part of this generation is believed to be 55 years old and the youngest is, or is turning, 40 years old in 2020.

As characteristics of this generation, The Generation X loves social media. Based on researchers, 81% of the Generation X has Facebook accounts, 35% in the U.S. have college degrees compared to the 19% of Millennials, and the Generation X middle-class income is on average $50,400/year compared to Millennials which only make $34,430 on average.


The Xennials generation is a "micro-generation" born between 1975 - 1985. They are described as having had an analog childhood and a digital adulthood. The first time this term was used and created, was in an article in GOOD magazine in September 2014 by writer Sarah Stankorb and the staff writer of GOOD magazine back at the time, Jed Oelbaum. These writers have defined this generation as a micro generation that you can find in the middle of the transition from the history of Generation X to the optimistic Millennials Generation.

People that are part of The Generation X and Millennials have different characteristics from each other, but the group of people which are born in between these generations during the history transition of the respective generations are seen to share characteristics from both generations. This overlap leads to the creation of a “micro-generation”.

Millennials, Generation Y, Gen Next

Millennials, Generation Y or even Gen Next are the same generation, just different names. This is the generation following Generation X and preceding Generation Z or in another name, iGen. The term Millennials, is used as the earliest of the millennials came of age during the turn of the millennium. The ones who got the most credits for naming the millennials are authors William Strauss and Neil Howe. They created the term in 1986, while the children born in 1982 were about to enter kindergarten.

Another definition referring to the Millennials is “Echo boomers” because of the rush they had in birth rates in the 1980s and 1990s, also because the people from this generation often are the children of the Baby Boomer Generation. They are also known because they came out of age in the Information Age. Research shows that Millennials spend 85% of their day on their mobile devices. Millennials often are also the parents of Generation Alpha.

iGen / Gen Z

Generation Z, Gen Z for short or iGen is the generation following the Millennials and preceding Generation Alpha. Gen Z’s are very comfortable using the Internet and social media since they used digital technology at a very young age. Most of Gen Z’s are the children of Generation X.

The first time the term Generation Z is believed to have been used is in September 2000 at the Advertising Age article. There are also other names for this generation. Some of them are: iGeneration, iGen, Gen Tech, Gen Wii, Net Gen, Homeland Generation, Digital Natives, Zoomers, and Plurals. Zoomer is a very popular name for this Generation since at least 2016, but is still not as widely used as Generation Z.

Research shows that 77% of Gen Z’s are very interested in volunteering in order to gain work experience. 88% of Gen Z said they are optimistic about their future. Nearly 25% of Gen Z thinks they are going to make $60,000 or more in their first job out of school. Gen Z starts to look for a job very early. Actually, 9/10 tries to find a job before graduation. They are also one of the most diverse generation in history.

Gen Alpha

Generation Alpha or Gen Alpha is the generation following Generation Z or Gen Z for short. The major part of Gen Alpha is exposed to technology at a very young age. The major part of this generation are the children of the Millennials.

The one credited for the term is the founder of Australian consulting agency McCrindle Research, Mark McCrindle when he conducted a survey in 2008.

Some predictions about Generation Alpha are that the first group of people that are part of this generation will reach adulthood by the 2030s. It is predicted that by that time, the population would be just under 9 billion and the major part of humans will be over 60 years old for the first time in history. If so, generation Alpha might delay standard life markers such as childbirth, marriage, retirements as did the previous generations.
