Approaches to understanding ethnicity
Ethnic groups can form a cultural mosaic in a society. That could be in a city like New York City or Trieste, but also the fallen monarchy of the Austro-Hungarian Empire or the United States. Current topics are in particular social and cultural differentiation, multilingualism, competing identity offers, multiple cultural identities and the formation of Salad bowl and melting pot. Ethnic groups differ from other social groups, such as subcultures, interest groups or social classes, because they emerge and change over historical periods (centuries) in a process known as ethnogenesis, a period of several generations of endogamy resulting in common ancestry (which is then sometimes cast in terms of a mythological narrative of a founding figure); ethnic identity is reinforced by reference to "boundary markers" – characteristics said to be unique to the group which set it apart from other groups.
