Generation X Ages | How Big Is Generation X? The age range for Generation X as of 2016 is 35 to 55 (my broadest definition). In 2011, the first Gen-Xer turned 50 years old and the youngest turned 30. We are currently the âsandwich generationâ in America. We are caring for aging parents and raising more than 50 percent of the nationâs children under 18.
The oldest Gen Xers were in high school when Prince arrived on the national scene with his fifth album and a single that spoke of the funkiest armageddon scene youâve ever heard of: 1999. It was a perfect Gen X dance song built on the idea that the worldâs about to end so, to hell with it, letâs dance.e was the perfect age to be a wise and cool big brother to Gen X. Prince may be a generational hybrid, able to speak to both Boomers and Gen Xers (and, now, Millenials), but heâs a special icon for my generation.
