The Millennial Generation is generally agreed to be those born between approximately 1982 and 2002. Neil Howe and Bill Strauss are credited with coining the term Millennials, as well as generally defining the birth years of this generation in their book Millennials rising: the next great generation. A few others disagree and define this generation as starting as early as 1979 or as late as 1984; additionally, there are even those who define the Millennial generation as ending as early as 1994.

There is no easy way to define a generation. In the past, many have used the change in birth statistics to define generations, but there are other ways to confirm the birth years of any particular generation that may make more sense (Howe and Strauss, 2000, p.40). One of the most interesting is to define generations based on what experiences they missed.
