Why is gen x called that?

Generation X, often abbreviated as Gen X, refers to the cohort born roughly between the early-to-mid 1960s and the early 1980s. The term "Generation X" gained popularity through a 1991 book by author Douglas Coupland, which characterized this group as disaffected and apathetic. The "X" symbolizes the uncertainty and lack of identity that defined the generation, contrasting with the more defined identities of the Baby Boomers preceding them and the Millennials following.
