The Baby Boom generation includes persons born in certain countries after the end of WWII (1945) but before the end of 1964. William Strauss and Neil Howe in their book Generations called this generation the Boom generation (they are no longer babies) and put the birth years of United States members of this generation at 1943 to 1960, not based on parental fecundity, but because of a common peer personality.
And I like the way Howe and Strauss divided the 'X' generation into 'Atari' and 'Nintendo' X-ers. I turn 40 next month, and certainly have very little in common with early boomers; however, the same could be said of my my tatooed and pierced brethren in the Nintendo wave of the 13th gen.
I was thinking about that book when I read this for the exact same reason. Don't have the book around at the moment, but I remember them talking about how those born in the early 60's did not belong in the boom generation.
Interesting reading the comments from the 1964-born "boomers" in the article above. They could have come right out of Strauss & Howe's description of the "Thirteenth Generation" (a.k.a. Generation-X).
