It comes from a Canadian writer by the name of Douglas Coupland who wrote a novel called Generation X. He’d heard his generation called “Twentysomethings,” “Thirteeners” (because they’re the thirteenth generation since the Declaration of Independence), “Post-Boomers,” and “Baby-Busters.” He didn’t like any of those titles. They were all inventions of Baby Boomers, and he, like many others, felt the Boomers had been especially judgmental of his generation. He was looking for a generic title, sort of a non-label, and that’s how he came up with “Generation X.”
