In the year 2000, the population was approximately 61 million, with over eighty different ethnic groups. The Oromo, Amhara, and Tigreans account for more than 75 percent of the population, or 35 percent, 30 percent, and 10 percent respectively. Smaller ethnic groups include the Somali, Gurage, Afar, Awi, Welamo, Sidamo, and Beja.
The urban population is estimated to be 11 percent of the total population. The rural lowland population is composed of many nomadic and seminomadic peoples. The nomadic peoples seasonally graze livestock, while the seminomadic peoples are subsistence farmers. The rural highlands economy is based on agriculture and livestock raising.
There are eighty-six known indigenous languages in Ethiopia: eighty-two spoken and four extinct. The vast majority of the languages spoken in the country can be classified within three families of the Afro-Asiatic super language family: the Semitic, Cushitic, and Omotic. Semitic-language speakers predominantly live in the highlands in the center and north. Cushitic-language speakers live in the highlands and lowlands of the south-central region as well as in the north-central area. Omotic speakers live predominantly in the south. The Nilo-Saharan super language family accounts for about 2 percent of the population, and these languages are spoken near the Sudanese border.
