What are the ages of those in the Gen X and Gen Z groups?

[Celerity]

15. The Homeland Generation is an American alternative name for Gen Z (but the dates some of the

promoters of the name use are non standard, and do overlap into the first part of Gen Alpha ( born 2013 to ???, but 2028 if we keep doing the 16 years to a Gen thing)

Etymology and nomenclature

The name Generation Z is a reference to the fact that it is the second generation after Generation X, continuing the alphabetical sequence from Generation Y (Millennials). Other proposed names for the generation included iGeneration, The Homeland Generation, Net Gen, Digital Natives, Neo-Digital Natives, Pluralist Generation, Internet Generation, Centennials, and Post-Millennials. Psychology professor and author Jean Twenge used the term iGeneration (or iGen for short), originally intending to use it as the title of her 2006 book about Millennials, Generation Me, before being overruled by her publisher, Atria Publishing Group. At that time, there were iPods and iMac computers but no iPhones or iPads. Twenge later used the term for her 2017 book iGen. The name has also been asserted to have been created by demographer Cheryl Russell in 2009.

In 2014, author Neil Howe coined the term Homeland Generation as a continuation of the Strauss–Howe generational theory with William Strauss. The term Homeland refers to being the first generation to enter childhood after protective surveillance state measures, like the Department of Homeland Security, were put into effect following the September 11 attacks. The Pew Research Center surveyed the various names for this cohort on Google Trends in 2019 and found that in the U.S., the term Generation Z was overwhelmingly the most popular, from then on calling it Gen Z in their research. The Merriam-Webster and Oxford dictionaries both have official entries for Generation Z.

In Japan, the cohort is described as neo-digital natives, a step beyond the previous cohort described as digital natives. Digital natives primarily communicate by text or voice, while neo-digital natives use video, video-telephony, and movies. This emphasizes the shift from PC to mobile and text to video among the neo-digital population. Zoomer is an informal term used to refer to members of Generation Z. It combines the shorthand boomer, referring to baby boomers, with the "Z" from Generation Z. Zoomer in its current incarnation skyrocketed in popularity in 2018, when it was used in a 4chan internet meme mocking Gen Z adolescents via a Wojak caricature dubbed a "Zoomer". Merriam-Webster's records suggest the use of the term zoomer in the sense of Generation Z dates back at least as far as 2016. It was added to the Merriam-Webster dictionary in October 2021 and to Dictionary.com in January 2020. Prior to this, zoomer was occasionally used to describe particularly active baby boomers.

Introducing the Homeland Generation (Part 1 of 2)

that article starts it at 2005, and says he choose it:

Why was 2005 chosen as this generation’s first birth year?

The 2005 date remains tentative. You can’t be sure where history will someday draw a cohort dividing line until a generation fully comes of age. But for now, 2005 is my best guess. History teaches that new generations first appear about one full phase of life, or about 18 to 24 years, after the first appearance of the last generation. Generational boundaries are also typically drawn 2 to 4 years before abrupt changes in the national mood. Millennials first appeared in 1982. That points to 2000 to 2006 as the opening window for the next generation. The reason I chose 2005 exactly—and again, this remains tentative—is that kids born in that year and after will recall nothing before Barack Obama’s presidency, the financial meltdown of 2008, and the seemingly endless Great Recession that followed.

BUT, if that is his reason, then it should be 2006 (as some 2005 borns will remember (even if vaguely, but I myself started to read when I was 3 and I deffo recall the end of 1999 (the fake Millennium end, which actually ended on Dec 31, 2000, when we completed 2000 years since Dec 31, 1 BC flipped to January 1, 1 AD), a couple months after I turned 3, as I was born late 1996, the last Millennial birth year) the 2007-2009 global financial crisis and also the year of 2008 before Obama was elected (and sworn in January 20, 2009)

My own micro Gen, the Zillennials (roughly 1992 to 1998 born) ends at 1998 because to be a Zillennial you should have at least some vague memory of 9/11, and have been under 10 as well when it occured.
