An ethnicity is defined by a shared cultural identity including factors like language, religion, customs, traditions, ancestry and history. Customs are specific behaviors or practices that are traditionally accepted within a particular society, location or time period. Cultures can also be classified based on their communication style, with high context cultures relying more on body language and implicit understanding versus low context cultures that are more explicit and straightforward. Discrimination occurs when groups or individuals are treated unequally or marginalized due to characteristics such as gender, age or skin color.
