Ethnicity refers to a group of people who share a common cultural and ancestral background. It can be based on factors such as language, religion, customs, and history. Research in the area of ethnicity aims to understand how individuals identify with and experience their ethnic group, how ethnicity influences social relationships and interactions, and how it contributes to cultural diversity and inequalities within societies. Researchers may explore topics such as ethnic identity formation, intergroup relations, discrimination and prejudice, social mobility, and the impacts of ethnicity on health, education, and employment outcomes. Studies in this field often involve examining the intersection of ethnicity with other social categories such as race, class, gender, and nationality.
