Generation X is the demographic cohort following the post-World War II baby boom, representing a generational change from the baby boomers, but there is debate over what this means because the end date of the baby boomer generation is disputed.
Others use dates similar to Strauss and Howe's such as the National Science Foundation's Generation X Report, a quarterly research report from The Longitudinal Study of American Youth, which defines Generation X as those born between 1961-1981 [REF].
