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.
But the media made them short so they could backfill Gen-X until it had an 18-to-20-year range, and add more kids to Gen-Y as they were born. The first Gen-X cohort of the 90s stopped in 1973, and Gen-Y began in 1974, ending in MAYBE 1990 at most. Thatâs all changed today.
