Most Ethnically Diverse Countries In The World

All of the world's most culturally heterogeneous countries are found in Sub-Saharan Africa.

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. Ethnic fractionalization is about demographics and socioeconomic distribution of distinct cultural groups in a country or territory. It is also the difference between one cultural group having dominance over another or cultural groups being independent of each other. The difference between majorities and minorities are also crucial in this respect as some minorities may be economically superior.

Ethnic Diversity in Sub-Saharan Africa

All of the world's most culturally heterogeneous countries are found in Sub-Saharan Africa. Central Africa, East Africa, Southern Africa, West Africa, two French territories, and African island nations all make up Sub-Saharan Africa. This group includes a total of 42 countries which at one time or another were colonies of European nations. Today, the Sub-Saharan African populations know how to speak and use one or more of six hundred Bantu languages and their former European colonist’s language.

Socioeconomic Implications of Ethnic Fractionalization

Ethnic fractionalization has resulted in perennial conflicts that have consumed the lives of these ethnic people. Illiteracy has increased or remained high in areas of conflict. The AIDS epidemic has also destroyed a majority of the region’s population. Other serious diseases continue to fester due to lack of doctors and medicines. Political and legal conflicts add to the confusion and has caused the collapse of economies in the region resulting in mass hunger.
