Why dont we try to resolve this issue on this talk page rather than going back and forth with edit wars  I believe a specific age range should be in the lead and there seems to be more or less a concensus that  is the most used first year  I dont think there is any ambiguity about thiswhether we agree or not and I dont happen to agree that  is the first year I dont think there is any question that  is the most widely used beginning yr for X  Also Generation Jones is certainly relevant to this  Its not that Wiki editors have to face the claim that a Generation Jones exists as you say  There is no question that many credible sources do believe that Generation Jones does exist and especially with its accelerated emergence recently it should be included in any discussion of the birth years of GenX since it is directly relevant
