This new version for Africa provides considerably more detail: more than 109,000 administrative units (83,000 of which are in South Africa), compared to about 800 in the first, 2,200 in the second version and 4,700 in the third. In addition, for each of these units a population estimate was compiled for 1960, 70, 80, 90 and 2000 which provides an indication of past population dynamics in Africa.
