At the behest of anthropology and sociology, in which the concept turns out to be routine, the subculture is the term used to refer to that group of people who share behaviors and beliefs, which turn out to be very different from those that prevail in the dominant culture of the community to which they belong.
Somehow a subculture is a group differentiated within a culture. Usually, its members gather for various reasons such as age, ethnicity, sexual identity, musical tastes and common aesthetics among the most recurrent.
Traditionally, the subculture be defined if same as opposed to the culture prevailing in your country or city of origin, meanwhile, it can be radical or not be, i.e. effectively introduce such mentioned opposition but no combat to the dominant culture, being able to live both perfectly.

Groups of people who get together because they share the same tastes there are many in all parts of the world, however, they do not form a subculture because they do not share physical appearances that we mentioned before and certain postulates, such is the case of skepticism and lack of hope in the development of the world that holds the Goth subculture.
