Following the terming of the generation following the Boomers “Generation X” some extended the “letter names” to call the following generation after that Generation Y and the next one after that Generation Z. Strauss and Howe seem to dislike those kinds of names though because it makes the Millennials (what they call X’s successor generation instead of Generation Y) like an extension of Generation X (like they mentioned in Millennials Rising).
How about Generations J, K, and L instead? Those names derive from “fashionable initial letters” for baby names during the respective period. Generation J encompasses roughly the late Xers and early Millennials when names beginning with J were fashionable such as Jennifer, Jessica, and Jason (the first and the last of those inspiring the title of Pamela Redmond Satran and Linda Rosenkrantz’s original name book Beyond Jennifer and Jason).
K was the fashionable letter during the time that the late Millennials and the early Homelanders were born (especially with spelling names that normally begin with a “C” with a “K” instead).
L now seems to be the new fashionable letter as we are nearing the midway point of the Homeland Generation, as S&R and Laura Wattenberg have posted on their blogs. If the pattern with J and K continues, L will continue its run on being the new fashionable letter until the early-mid part of the “New Prophet” generation (calling this unnamed future generation by using the Strauss and Howe archetypes). Will the pattern continue and M become the fashionable letter 20 years or so from now?
