How has the history of the twentieth century affected the extent of female disadvantage in child survival in China, South Korea and India, and how has this in turn shaped spousal availability and marriage payments? These three countries have similar kinship systems which generate discrimination against girls, and they show the highest levels of excess female child mortality in the world. This article explores how the extent of excess female child mortality was influenced by historical events in these countries in the period 1920–90, and discusses some of the substantial social ramifications of resulting changes in sex ratios. The authors hypothesize that these changes encouraged the retention of brideprice in China while dowry became the norm in India, and illustrate how these demographic changes have influenced the extent and manifestations of violence against women.
