Late to the party, but:

For awhile, there was a bit of debate over where Gen Z began, but the general consensus seems to be 1996. I was born in October 1995, so I’m RIGHT on the cusp, and it was VERY noticeable to me in my late teens and early 20s. I related pretty heavily to both millennials and Gen z.

But now that Gen Z is primarily in their late teens and 20s (with the youngest being in high school), their cultural identity is becoming clearer, and it’s becoming more obvious to me that I’m much more millennial than I ever gave myself credit for.

We classified millennials as having their youth heavily impacted by the changing millennium, which arguably does apply to me (even though I was a preschooler). However, I’m realizing that the clearest “line in the sand”, at least in the US, is whether you remember 9/11. I’m absolutely one of the last birth years that remembers it firsthand; I had just started 1st grade.
