Testosterone Nation

Mara Hvistendahl reports on the consequences of China's one-child policy:

Preliminary returns from the first generation of population-controlled kids suggest how all those unwanted men might fill up their time. Over the past decade, as the boys hit adolescence, the country's youth crime rate more than doubled. In December, Chinese Society of Juvenile Delinquency Research Deputy Secretary General Liu Guiming told a Beijing seminar that today's teens were committing crimes "without specific motives, often without forethought."

...as Chinese couples make more money, fertility is naturally declining-- meaning that today's bachelors will form an even larger proportion of China's future population than officials expect. Wang Feng, a sociologist at the University of California-Irvine who's part of a group of scholars advocating phasing out the one-child policy, says the outlook is grim: "Each successive birth cohort is going to be smaller. When younger cohorts get smaller, you have fewer females. It's a double whammy."
