"Generation X" (which came from a book title in the 90s but was an already existing, unrelated title of another book in in 1965 NOT about 'this' generation) is also known as Gen-Reagan or Generation Reagan, having grown up and started college during the two terms of Ronald Reagan with older members of this window of declined birthrate also remembering the failed presidential policies of Jimmy Carter.
Actually the boomers are the Reagan generation, Reagan was the first president that all boomers were old enough to vote for, that was the election of 1984, they manned his military and attended college under him, they started entering politics under him. The 1980s is when the boomers started emerging.
