Ethnicity is the identity of similar groups of people connected to their ancestral, social, national, cultural, and common language. Important factors form the basis of a person’s ethnicity such as joint ancestry, origin myth, homeland, history, cultural heritage, and language. Cultural heterogeneity is about the existence of diverse cultures in a certain population living in a territory or country.
The demographics and socioeconomic distribution of distinct cultural groups in a country or territory is called ethnic fractionalization. The data below is based on a study conducted by Fearon, where 1 is the most culturally diverse and 0 is the least. This measure of cultural diversity is heavily based on languages spoken, as language can be a convenient indicator of ethnicity and diversity. Papua New Guinea is the most diverse country in the world, followed by Tanzania, the Democratic Republic of the Congo, and Uganda.
