The 77 million Americans born between 1977 and 1997.

Generation Y is a term designating a cohort of people born immediately after "Generation X" and is only one of several terms used to describe roughly the same group of people. There is however no consensus as to the exact range of birth years that constitutes "Generation Y", nor whether this term is specific to North America, the Anglophone world, or people worldwide. The only consensus, by way of its relation to the term "Generation X," is that those born in Generation Y must follow Generation X.
