Premise: Demography ( from prefix demo - from Ancient Greek δῆμος dēmos meaning `` the people '' , and - graphy from γράφω graphō , implies `` writing , description or measurement '' ) is the statistical study of populations , especially human beings . Generation X , or Gen X , is the demographic cohort following the baby boomers . There are no precise dates for when this cohort starts or ends ; demographers and researchers typically use starting birth years ranging from the early-to-mid 1960s and ending birth years ranging from the late 1970s to early 1980s .
Hypothesis: Generation X features birth years from the 1960s and has been studied.
