A generation gap refers to the difference in values, beliefs, and opinions that exist between members of different generations. These differences can relate to a wide range of areas, including politics, language, work, demographics, and values. The term "generation gap" was first used in the 1960s to describe the cultural differences between baby boomers and their parents. While generational differences have always existed to some degree, the breadth of these differences has widened in the 20th and 21st centuries.

Generational gaps can lead to misunderstandings and conflicts, but it is possible for generations to overcome their differences and maintain functional relationships. Sociologists use nomenclature to refer to different generational segments, such as Gen Z, born between 1996 and 2012, who are called “digital natives” because they have lived with digital technology their entire lives.

Generational gaps are caused by age and the situation of the world at the time one generation has grown up. For example, the beliefs and perceptions of those who grew up during the Great Depression and World War II are likely to differ from those who grew up during the 1960s and 1970s.

Generational differences have long been a factor in U.S. politics, with the potential to shape politics well into the future. Pew Research Center defines the Millennial generation as adults born between 1981 and 1996, and those born in 1997 and later are considered part of a separate (not yet named) generational cohort.

In conclusion, a generation gap is a difference in values, beliefs, and opinions that exist between members of different generations. These differences can relate to a wide range of areas, and while they can lead to misunderstandings and conflicts, it is possible for generations to overcome their differences and maintain functional relationships.
