Fertility differentials in the Sudan (with reference to the nomadic and settled populations) * This paper is based on a chapter from a Ph.D. thesis completed at the London School of Economics, under the joint supervision of Professor D. V. Glass and Dr. J. G. C. Blacker, to whom I am deeply indebted for guidance, criticism and suggestions. I am also grateful to the Ford Foundation and the Population Council Inc. for the grants which made this work possible. [electronic resource]
