The Pew Research Center has enough authority that their opinion matters on stuff like this.  And they just announced the official definition of a millennial:  Anyone born between 1981 and 1996.  So anyone 22 to 37 this year.

That means millennials were between age 5 and 20 on 9/11,  ages 12 to 27 when Obama was elected and ages 7 to 22 when Sammy Hagar temporarily reunited with Van Halen.

Here’s Pew’s full breakdown of the generations . . .

1.  Silent generation:  Born 1928 to 1945.

2.  Baby boomers:  Born 1946 to 1964.

3.  Generation X:  Born 1965 to 1980.

4.  Millennials:  Born 1981 to 1996.

5.  And for anyone born after 1996, there’s no official name yet for the generation.

***Side Note*** I’ve heard people call them Generation Z. -Monica
