Ziaul,
I'm not sure I understand exactly what you're asking so I give it a couple of answers.
1) If you mean as Gen Yers age do their characteristics vary, I would say yes as part of what we see is due to their youth & they are growing & maturing & so some of this is related to being young.
2) If you are referring to where they fall in the Gen Y band, I would also say yes there is variation. Those who are the earliest in a generation band are often very similar to both generations.
