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.
History of slavery
The Anti-Slavery Society estimated that there were 2,000,000 slaves in the early 1930s Ethiopia, out of an estimated population of between 8 and 16 million. Slavery continued in Ethiopia until the brief Second Italo-Abyssinian War in October 1935, when it was abolished by order of the Italian occupying forces. In response to pressure by Western Allies of World War II Ethiopia officially abolished slavery and serfdom after regaining its independence in 1942. On 26 August 1942 Haile Selassie issued a proclamation outlawing slavery.
