What the hell is going on with the timespans? The Boomers starting in the middle of WW2? Millenials going until 2004?
Wait, are these the definitions used by Strauss and Howe? They concocted the famous cyclical theory of the generations and have been using a definition of Baby Boomers that includes those
born before WW2 ended?! That's like the only generation where there's a case to be made for a hard starting point, and it should
never be before the end of WW2.
I mean, all generational definitions tend to be quite arbitrary, and generations, to the degree that they do exist, should be viewed as ambiguous, nebulous entities rather than discretely defined, but the Baby Boomers are unique in the sense that they also constitute a distinct demographic spike. If you aren't going to keep the starting and ending years open-ended, and I don't think Strauss and Howe do, the starting parameter for the baby boomers is basically required to be 1946.
