The boundary between a generation, particularly the line between Gen Y and Gen Z, has been discussed to death on this forum. Granted, it's a pretty inane discussion to begin with, as a one or two year age difference is completely nugatory, however, I believe that the reason this gets discussed so much is probably because most people born in the mid to late 90s are still generally immature and still haven't gotten out of that phase of wanting social acceptance, albeit luckily there does seem to be a rise in the number of mid to late 90s borns accepting the Gen Z label and even taking pride in not being Millennials, probably due to their toxic leftist reputation.
Still though, when you hear someone in their 40s or older talk about "their generation", they're not talking about the arbitrarily set cohort they belong to, they're talking about those close to their age.
When an older Boomer born in 1946 or 1947 talks about their generation, I can guarantee you they're not including younger Boomers born in the late 50s early 60s, nor are they excluding younger Silents born in 1944 or 1945.
The American Generation system is also heavily flawed. There are too many definitions, the lines are set arbitrarily, and are often based on limited research that is impossible to foul proof.
There is a better system to use to determine which cohort you are in, that system is the Chinese Zodiac, a system where each 12 years are all named after 12 different animals. After each 12 years, the animal gets repeated. So using this method, your personal generation, regardless of which year you were born, would be in between the range of 12 years older than you and 12 years younger than you. Perfect if you ask me, as culturally, those 12 years apart all show a generation gap in their own way.
For example, let's use the Boar Zodiac Sign.
Those born in 1935 came of age in the early/mid 50s when conformism was key, and when teenage culture was just beginning.
Those born in 1947 came of age in the mid 60s when the Vietnam War was starting and when Flower Child culture was taking off.
Those born in 1959 came of age in the late 70s when Star Wars, Atari 2600, and early home PCs came out and when disco was popular.
Those born in 1971 came of age in the late 80s when hip hop was taking off and when the Cold War was beginning to end.
Those born in 1983 came of age in the early 00s when the dot com bubble busted, 9/11 occurred, and when DVD was becoming popular.
Those born in 1995 came of age in the early/mid 10s when the leftist and alt right movements were starting out and when Snapchat and Vine were taking off.
Every birthyear aforementioned is a Boar year in the Chinese Zodiac, and all of them came of age in a time different enough to truly be considered an all out generation gap, regardless of which year you were born.
So therefore 12 years would be a generation gap, with each 3 years leading up to 12 all elevating to a generation gap.
0-2 year difference = Your core age group.
3-5 year difference = Pretty different, but no signs of a generation gap yet.
6-8 year difference = Earliest signs of a generation gap.
9-11 year difference = Semi generation gap.
12+ year difference = Generation gap.
What do you guys think of this formula?
