Ethnicity refers to anything related to a group of people who share a common cultural heritage, language, or ancestry. Ethnicity is often an important factor in understanding social, political, and cultural dynamics within and between countries. Ethnic groups often have a common cultural identity that includes language, traditions, customs, and often a shared history or ancestry.
