Ethnicity is a social construct based on shared cultural heritage and identity. It is often expressed through shared language, religion, values, beliefs, dress, and other cultural markers. Ethnicity can be a powerful source of social identity and community, with people feeling a sense of pride and connection to their ethnic group. However, it can also be a source of inequality and discrimination. For example, those from minority ethnic backgrounds may be subject to negative stereotypes, exclusion, and prejudice in society. Ultimately, ethnicity is a fluid concept that is continually changing and evolving.
