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 Baby Boomers were the generation born during or just after World War II; there was a worldwide increase in birthrate for about 14 years (1945-1959). The end of the baby boom period is cited by various sources as early as 1954 or as late as 1965 -- see Baby Boomers.
