Wikipedia: ALLE GENERATIES SINDS 1883

1883-1900 (18 years):
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. Very few Americans from this generation are currently alive.

1901-1924 (24 years):
The G.I. Generation, the generation of veterans that fought and won World War II, which are a subgroup of the global Post-World War II baby boom demographic, later to become the Establishment, and the parents of children who would later become the Baby Boomers (born 1946-1964). Journalist Tom Brokaw dubbed this the Greatest Generation in a 1998 book of that name.

1925-1942 (18 years):
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.

1942-1953 (12 years):
The Baby Boomers (Boom Generation) were the generation born just after World War II, 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.

1954-1965 (12 years):
Generation Jones was the generation of actual children in the 1960s, which came of age in the middle to late 1970s and early 1980s. The election of Barack Obama to the U.S. Presidency created significantly increased awareness of this generation as many prominent sources referred to Obama as specifically a member of Generation Jones.

1966-1980 (14 years):
Generation X is the generation born between approximately 1965 to 1980, and connected to the pop culture of the 1980s and 1990s they grew up in. Other names used interchangeably with Generation X are Reagan Generation, 13th Generation, and Baby Busters. Most of this generation are children of The Baby Boomers and The Silent Generation. Those born before 1973 spent most of their teen years in the 1980s.[1]

1981-1995 (14 years):
Generation Y, or "Millennials" are the largest generation in American history. Born between 1981 and 1995 they are 95 million strong, compared to 78 million Baby Boomers. Generation Y could be divided into 2 parts: the Cold Y Generation,noted for their birth during the Cold War between 1976-1990, and the Post-Echo Generation that follow after 1990 who only have a passing memory of the 20th century.

1996-present (14 years?):
This latest generation is known as the text generation, since they grew up with cell phones. Early names have included "Generation Z", "Generation V" (for virtual),"The New Silent Generation", the "Internet Generation", the "iGen" and "Gen @." Generation Z are very young but active consumers, and very connected, being born into a world of ubiquitous digital communication connectivity.
