I was telling my Mom about sub-generations. Notably for younger Boomer/older GenX they’re called the Brown Generation (being the generation affected in the aftermath of 1954’s Brown v Board of Education) for having experience in a racially segregated classrooms then in the middle of their schooling have integration. I bring it up since for example my Pops didn’t had mostly black classmates until he went to university, but my mom started with mostly black classmates only having integration when the black high school in her town closed and merged with the white high school (… named after a Confederate general).

This leads to Xennials. Our defining attribute was experiencing life before the Internet and cell phones we had to deal with insane technological advances as they happened in real time. It’s like remembering comic books in supermarkets, then seeing them move to their own places then seeing the medium go digital. Or remembering a See and Say/Touch and Tell toy as a toddler then move to cassette read along as child to having the concept made as an app as an adult, like remembering phonographs/record players transition over to cassettes and Walkmans to CD’s and Discmans to MP3’s to now playing music from your phone (the current digital Swiss Army knife). The idea of always being on ground that can change overnight due to technological advances.

I’d assume the next micro generation would be with younger Gen Z/older Alpha defined by the dealing with C19 lockdowns while in school and the effects afterward.
