"Ethnicity" is the notion of an analogy between place, group and culture. Assigning individuals to ethnic groups is therefore mostly linked with implicit characterisation. In the context of political and social discourses, ethnic ascriptions often give rise to weighty discourses about segregation. This is reflected in the media by terms such as "parallel society". In the "multiculturalism" model, "cultural diversity" has positive connotations, but the sole focus on origin and culture leads to over-simplification. It distinguishes between "insiders" and "outsiders". In supranational contexts, ethnicisation processes often take the form of political projects which serve to promote the recognition of a national status vis-à-vis other nations by means of territorial demarcation. "Self-ethnicisation" is generally associated with claims to one's own history, values and traditions. In this context, culture is seen as an inheritance that is passed on from generation to generation, which makes ethnicity appear to be a naturally given fact while heterogeneous, hybrid realities are ignored. Ethnicisation processes are never fully completed, clear or precise, but are instead embedded in dynamic processes and also affected by local and global factors.
