There are nine recognized ethnic groups according to the government of Eritrea. An independent census has yet to be conducted, but the Tigrinya people make up about 55% and Tigre people make up about 30% of the population. A majority of the remaining ethnic groups belong to Afroasiatic-speaking communities of the Cushitic branch, such as the Saho, Hedareb, Afar and Bilen. There are also a number of Nilotic ethnic groups, who are represented in Eritrea by the Kunama and Nara. Each ethnicity speaks a different native tongue but, typically, many of the minorities speak more than one language.
