What is a sub-culture?

A subculture is a group of people with a culture (whether distinct or hidden) which differentiates them from the larger culture to which they belong, for example, if a particular subculture is characterized by a systematic opposition to the dominant culture, it may be described as a counterculture.

Subcultures are most commonly identified by clothing because this is visible but can also be indentified by music, lifestyle and values.
