Preference of boys over girls is still hanging on in Chinese society, urban as well as rural. And it killed a mother who just gave birth to a cut little girl. Worse, the husband’s family treated the new mother badly and the husband raped his wife before she committed suicide with their baby girl just few days old. See A New Mother Leaps To Her Death

In the past two decades in China, female births have declined markedly compared with male births. The official figure – which some say is slightly low – is 117 boys for every 100 girls, based on a 2000 census. In ordinary populations, the split is closer to 104 boys for every 100 girls. Skewed sex ratios are also appearing elsewhere in Asia, particularly India, where the ratio in the state of Punjab is 126 to 100. A tilt toward male births is also beginning to be 126 to 100. A tilt toward male births is also beginning to be seen in the Caucasus and parts of Latin America and Eastern Europe.
