Spatial distribution of radiocarbon dates for the Iron Age in southern Africa

The large number of radiocarbon dates for Iron Age sites in southern Africa have been sub-divided into five different age categories and their distrib ution plotted on maps covering South Africa and the adjacent area. These di stribution maps, together with the previously presented variations in the n umber of settlement sites through time, show a strong correlation with the changes that occurred in the climate. The evidence confirms the positive re lationship between temperature and rainfall over the past two millennia.
