we've been focusing on boomer retirement so long that....
you do realize that gen x is actually starting to retire now, right?
most people that study this cut the boomers off before 1955, and introduce a transitional generation from 1955-1965 where people could self-identify either way. and, if you were born in 1955, you are now 65 years old.
both of my parents were born in that transitional period, but they're both clearly boomers, if tail-end boomers. i'm also a cusper (1981), and i strongly identify as the last gen xer. the cusp breaks in the other direction; my grandmother, who had two children before she turned 20 years old, is also a boomer, meaning she's of the same cultural generation as her children. my dad's parents were not boomers. and, both of my sisters are quite clearly millennials.
i have a legit gen x aunt who isn't far from retirement, but that's about it.
