According to the dates, I'm Y. But I have absolutely nothing in common with those people and I hate them.

Coro, I think you're probably right. X,Y, and Z seem really to be only 2 different generations...pre-internet and post-internet.

Early GenY, but really feel more like a GenX.

Late Gen X by those numbers. I find it interesting that the generations (even going back to the early ones listed) are growing smaller.

Greatest Generation: 23 years
Silent Generation: 20 years
Baby Boomers: 18 years
Gen X: 17 years
Gen Y: 12? years
Gen Z: 18 or whatever.

I'm with LK.. I think we're only on the trailing edge of whatever will shake down to be the second post-Boomer generation. I don't know whether that means that Gen Y will be subsumed, split, or greatly expanded to crowd out whatever people think Z is (but really, how can you have a generational identity for a group whose oldest members are barely 20, depending on whom you ask?)...

My guess is that Gen Y (and maybe even the last third of Gen X, which may have a bleed-into-effect on how the rest is viewed) may find that they still haven't found their definitive experience as a generational identity, and so I expect those boundaries to change dramatically over the next decade to fifteen years.

In other words, what Coro said, for the most part.

I wouldn't be surprised to see Gen X remembered as the generation that built and shaped the Internet.

I suspect Gen Y will be remembered as the generation that commoditized it. As such, I support re-dubbing Gen Y "The iPhone Generation."

You have 6 fingers?

I'll dial it on my iPhone if you like.

Someone was looking for you.

Generation X was named because the event that would actually define them as a group had not yet happened at the time when people were trying to decide what timespan would encompass them. Frankly, there will never be an actual name because their parents and grandparents saw that the Gen X label would stick long before they were ever going to make the contribution to society that they might be best known for.

Look at where Y stops. The best definition we currently have for Generation Y is, "People who have graduated from high school, but are not Gen X." That's it. That's what we've got. That's why it's so small. Generation Y currently stops in 1993 (not explicitly stated, but you can bet that's the dividing line). Next year, it will go all the way to 1994. That's why they don't give a year, just "mid 90s," but if you notice, Generation Z starts in "early 90s" - so there's a two or three year overlap between Y and Z where someone is in both?
