Finally some good news on the gender imbalance front, if only in Shanghai. It seems that the city's population officials are increasingly optimistic about the boy-girl ratio now that it's implemented specific policies for migrant workers, the most likely group to contribute to the dearth of female infants. These policies include enhanced education, subsidies and more training opportunities for girls, as well as a ban on fetus sex checkups and abortions after 7 months (yes, China allows third-trimester abortions normally) unless there's a medical reason. Now officials say, more migrants are giving up the traditional "boys are best" mentality.
