Ethiopia's population is highly diverse with different languages and ethnic groups. Most of its people speak a Semitic or Cushitic language which are both part of the Afroasiatic language family, while others speak Nilo-Saharan languages. The Oromo, Amhara, Somali and Tigrayans make up more than three-quarters (75%) of the population, but there are more than 80 different ethnic groups within Ethiopia.
