I'm technically on the border of really old millennial, or really young Gen X.

I literally have nothing in common with the average millennial, I claim Gen X and I'll happily argue that '81 counts.

While the term "Millennial" is often used for those born from 1981 to 1996, the year 1981 is considered a "cusp" year, with some sources placing it as the last year of Gen X and others as the first year of the Millennial generation, according to Pew Research. Those born in 1981 might identify with either generation, depending on their experiences and the specific criteria used.
