ABSTRACT
At the present time, with far-reaching changes taking place in many of the countries of inter-tropical Africa, it is especially important that all political, social or economic policies should pay heed to the number, distribution, characteristics and inclinations of the population. Yet the course of ordered evolutionary development will also depend on the availability and use of sufficient knowledge of the people of Africa themselves. In fact collections of equal interest and diversity could be made which omitted British Africa altogether. In some African territories—Ethiopia, Liberia and the former Somaliland Protectorate—the first censuses have still to be attempted and only rough estimates of their populations exist. The studies of population mobility by Southall and Mitchell take the latest census results, together with a great deal of other historical and economic information, and use them to investigate changes and movements of population in East Africa and the Federation of Rhodesia and Nyasaland.
