The anthropometric measurements made by Professor Nigel Barnicot in 1966 and 1967 on 126 male and 110 female adult Hadza, a group of hunter-gatherers of the Tanzanian savanna, are analysed. Sex dimorphism of subcutaneous fat is particularly high in the Hadza, which suggests a relatively better status of the female sex than in other African societies. The Hadza males are among the leanest Africans. However, they are above the average in weight-for-height, owing to a much larger muscle mass. Sex dimorphism of stature is higher in the Hadza than in the average African population, but much lower than in Europe. Among other factors, attention is drawn to possible differences between societies in inequality of the sexes in feeding during growth.
