I liked the other Poll in this discussion but felt it didn't go into enough detail. As a member of a mini-generation I think they were casually lumped in with other groups not basing it on actual cultural experiences that tie a group together. While it might not be perfect I think this is probably a more realistic spread.
Here's how I see it:
The Silent Generation(1927-1940) These guys were born before most of WW2 and too young to participate in it. The majority were born during the Great Depression of the 1930's. 14 years
Rock and Roll Generation (1941-1945) This mini-Generation born during WW2 pretty much created Youth Culture in America in the middle 1950's when as teenagers (and pre-teens) many broke away from their parents and started swinging their hips and dancing to a new music called Rock and Roll by artists like Elvis Presley, Buddy Holly, Chuck Berry and Little Richard. It was quite rebellious at the time. The movie American Graffiti is a good representation of them. Most of the members of the Beatles, Rolling Stones, The Kinks, as well as Bob Dylan, Brian Wilson and other 60's icons were born here. They were heavily influenced by first-generation Rock. As John Lennon once said "If there was no Elvis, there would be no Beatles. 5 years
Baby Boomers (1946-1959) Much maligned generation with a BIG birthrate was actual instrumental in creating needed social changes, but caused problems as well for future generations. These were the Vietnam vets and the hippies that were part of Woodstock Nation, but also later Boomers (Shadow Boomers) like Bill Gates and Steve Jobs helped facilitate the flow of technology. This generation grew up in the turbulent 1960's with assasinations, draft cards (male), protests, potent drugs, and much of the best of classic Rock. 14 years
Generation Jones (1960-1964) This BIG birthrate mini-Generation was sometimes called the Lost Generation or Punk-rock Generation and has been claimed by both Boomers and X, but doesn't fit either group. This was the generation that came of age with the original punk-rock/new wave movements, as well of the first mass-produced Personal Computers, the Apple II. Also, the first generation of fans to witness the original Star Wars in the theatre and to play the first video games, whether at home with Pong or at the arcades with Space Invaders, Asteroids, or Defender. They share 80's MTV and "Brat-Pack" with X. 5 years
Generation X (1965-1976) Birthrates decreased in this generation as the Boomers of the 60's started using new birth controls to minimize pregnancies. There was a continuing rise in divorce rates and 2 income households in the 1960's and 1970's, so much so that X is often called the "latch-key" generation because of the lack of adult supervision. They played videogames on the first Nintendo consoles (NES and SNES) and the arcades. They were also deeply tied to MTV in the days when MTV actually played music videos. 12 years
Xennials (1977-1981) These guys grew up with grunge, Tupac, MTV reality shows , and everything 90's. They grew up with Windows '95, 56k modem, and the rapid ascent of AOL, Pentium Computers, Quake, SNES/N64, Playstation and the internet. My So-Called Life is a good representation of Xennials circa 1993 and 1994, pre-internet. 5 years
Millenials 1(1982-1991) The first Millenials group came of age with cel (dumb) flip-top phones, Windows 98/2000/XP, AOL chat rooms, Ocarina of Time, Diablo 2, Starcraft, Halo, etc. Very aware of events of 9/11. 10 years
Millenials 2 (1992-1996) The 2nd group of Millenials came of age with smart phones, Windows 7, Facebook, Youtube, Twitter, Reddit, and numerous dating websites. Not much emotional impact of 9/11 for most. 5 years
Generation Z (1997-?) The generation that grew up on Game of Thrones and Marvel movies. Deep into social media and the tech world, but not aware of 9/11.
Well, I tried to write some things out but I'm interested to hear where you are on the chart and some more insights into your generation that you can relate to us that make your group distinct.
