The Lost Generation was a term originally used to identify a group of American literary expatriates living in Paris in the 1920s and 1930s; it is now used more generally to describe the generation of young people who came of age in the United States during and shortly after World War I.

The Greatest Generation is the worldwide generation of Allies that served in World War II. This group overlaps with the G.I. Generation, the generation of vetrans that fought and won World War II, later to become the Establishment, and the parents of children who would later become the Baby Boomers.

The Silent Generation was the generation born between the two World Wars, who were too young to join the service when World War II started. Many had fathers who served in World War I. (1925-1945)

The Baby Boomers were the generation born during or just after World War II (between 1946 and 1964), a time that included a 14-year increase in birthrate worldwide. Baby Boomers in their teen and college years were characteristically part of the 1960s counterculture, but later became more conservative, eventually gave birth to Generations X and Y. Most academic and demographic literature uses 1946 and 1964 as the cutoff years of the Baby Boom generation.

Generation Y, also known as the Echo Boom, or Millennial Generation, grew up with many world-changing events including the rise of mass communication, the Internet, and the 9/11 terrorist attacks. The Y Generation is known as a Culture War "battleground" with growing disagreements between conservative and liberal perspectives. (1976-2001 is the widest possible definition commonly cited.)
