China's population passes 1.3bn

According to BBC World China's population passed 1.3bn early Thursday with, very fittingly, the birth of a boy. The main interesting statistics in the article is that among registered births boys outnumer girls 120 to 100 (the expected numbers are 105 boys to every 100 girls). The numbers are obviously higher than in India, which is the topic of some of my current research (see this post), but given that India does not have a one-child policy the difference is not a large as one might expect.
