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.
Gen X goes from 1965-1982. One thing people forget about when it comes to defining generations is birthrates. Millennials are known as the New Boomers, and the rise in births actually started with those born in 1983, and ended with those born in 2001.
