Generation X, often called Gen X, generally refers to the demographic cohort born between 1965 and 1980. This definition is widely accepted by sources such as the Pew Research Center, the U.S. Census, and major media outlets. Some slight variations exist, with a few sources extending the endpoint to 1981 or starting a few years earlier in the early 1960s, but 1965 to 1980 is the most common range used. In 2025, this means the age of Generation X members ranges roughly from 45 to 60 years old. They are the generation following the Baby Boomers and preceding the Millennials, sometimes called the "middle child" generation due to their smaller size relative to the other two cohorts.
