An urban tribe or subculture is a microgroup of people who share common interests in metropolitan areas. The members of these relatively small groups tend to have similar worldviews, dress styles and behavioural patterns.
Do they have any common political views or ideologies? The five political perspectives, social attritudes or ideologies are radical (far left), liberal (left), moderate (middle), conservative (right), and Reactionary (far right).
Youth subcultures offer participants an identity outside of the dominant traditional culture at social institutions such as family, work, home and school. The members' socioeconomic class, gender, intelligence, conformity, morality and ethnicity are also important when fitting in an urban tribe. What is this in-group mentality about? What do they behave like?
