Traditionalist, born between 1925 and 1945
Baby-boomer, born between 1946 and 1964
Generation X, born between 1965 and 1981
Millennial, born between 1982 and 2000
And anyone boom after 2000 is living without a label.
Ok, I concede. Post 2000s generation is a generation with a label in flux. Their labels are Generation Z, iGeneration, iGen, and post-millennials. As for the years, there is no agreement on the exact dates of the generation with some sources starting it from the mid or late 1990s (note the overlap with Millennials) or from the mid 2000s (leaving the beginning 2000s unlabeled..poor lost generation).
