I agree, and I think categorizing generations is always going to be messy. But I think the Oregon Trail Generation/Xennials just seems to be more distinct than most other micro generations. I'm pretty much in the middle of the commonly accepted millennial age bracket and would still consider myself more of a Xennial based off the broad characteristics that have been described, despite falling outside that rough '86 cutoff by a couple years. I know part of it is probably due to how much Millennials get shat on, but it feels like the "Millennial Generation" is an especially weird generation where half the people that are supposedly in it don't feel like they belong with the other half and many resent the label. To me, the Millennials born after '90 seem quite distinct from those born before '87 and I feel like I'm in the middle and identify more with the Xennials. I'm no sociologist, though, this is just my limited subjective experience.
