At the outset of the 1970s it is estimated that there are upwards of one million refugees in Africa, with about equal numbers from independent African states, and from non-self-governing and minority-ruled states. The largest single group are the Angolan refugees in Congo-Kinshasa, now estimated to number 400,000. Other large groups of refugees are from Rwanda, Sudan, and Guinea-Bissau. There are also smaller groups from Congo-Kinshasa, Ethiopia, and Zambia, as well as from Mozambique, South Africa, Namibia, and Rhodesia.
