As already stated, the very VERY oldest X'ers are. 
  
If we're going to be that loose, being of 1984, I could try and squeak into the X'ers, too. 
  
But, by most accounts, I'm a Millenial.  
  
But Millenial technically stretches into the early 2000's. And, Jesus, if you were born in 2002, the year I graduated high school, you came (or are coming up) WILDLY different than me, thanks almost entirely to the mobile/internet age, which is all they've ever known.
