  I completely agree with the others here who say that '65 is clearly the year by far most used for Gen X.  It's not a question of original research, it's a question of how the vast majority of people and writers and sources view the beginning of Gen X.  I thought we all went through this awhile agao and came to some kind of at least temporary compromise.  Don't understand why this is being pushed again, but I know there are many of us who feel strongly about '65 being the first year that is commonly used.
