Adam S. Kirby, "From ashes of tragedy comes Generation 9/11," The Marquette Tribune, November 16, 2001
'Generation 9-11 can learn ... from your profound sense of duty and honor, and your spirit of selfless service the significance (of which) we are only now beginning to heartily embrace,' he said."
Laura Yuen, "Remembering Sacrifice, Honoring Duty," The Lexington Herald Leader, November 11, 2001
Today's phrase appears to have been coined by whatever Newsweek editor decided to title that magazine's November 12 cover story, "Generation 9-11." There are citations in the media prior to November 12, but they're all discussing the forthcoming Newsweek article. I did manage to find four articles that used Generation 9-11 (or Generation 9/11) without referencing the Newsweek piece, so it's possible that this label may have some longevity. (Unlike previous attempts such as Generation Y and Generation D.)
