At the beginning of the twentieth century in South Africa, the sex ratio for black children under five years was one of the lowest ever recorded. Sex ratios also differed markedly by racial group. Those for white children remained almost invariable, with more boys than girls, while black children had a clear majority of girls, a situation that the literature has almost completely overlooked. The reasons are still not completely clear. Although sex ratios at birth show more births of boys than girls, boys’ mortality was higher than girls’ mortality. Why boys’ mortality was so high and why, as a consequence, the twentieth-century under-five sex ratio for black children was so skewed towards girls, a ratio much lower, for example, than the sex ratios of pre-industrial European countries, remains unanswered. We suggest several possible explanations. The most likely explanation, we argue, was a preference for girls.
