Ethiopia
Ethiopia's population has grown from 33.5 million in 1983 to 87.9 million in 2014. The population was only about 9 million in the 19th century. The 2007 Population and Housing Census results show that the population of Ethiopia grew at an average annual rate of 2.6% between 1994 and 2007, down from 2.8% during the period 1983–1994. Currently, the population growth rate is among the top ten countries in the world. The population is forecast to grow to over 210 million by 2060, which would be an increase from 2011 estimates by a factor of about 2.5.
Oromo people
The Oromo people (; , "’Oromo") are an ethnic group inhabiting Ethiopia. They are one of the largest ethnic groups in Ethiopia and represent 34.5% of Ethiopia's population. Oromos speak the Oromo language as a mother tongue (also called "Afaan Oromoo" and "Oromiffa"), which is part of the Cushitic branch of the Afro-Asiatic language family. The word "Oromo" appeared in European literature for the first time in 1893 and then slowly became common in the second half of the 20th century.
