Millennial is an identity given to a broadly and vaguely defined group of people. There are two wings of "Millennial" that are often at odds with each other: Generation Y (people born between 1981-1991) and Generation Z (born between 1991-2001). People of Generation Y often have characteristics similar to Generation X, which is why Generation Z will confuse Generation Y with Generation X and then claim to be the generation that represents "MIllennial," when in fact, birth years for Millennial range from about 1981-2001, just as the birth-years for Baby Boomers ranged from 1946-1964.
