Researchers may have ‘found’ many of China’s 30 million missing girls

Academics often talk about between 30 and 60 million “missing girls” in China, apparently killed in the womb or just after birth, thanks to a combination of preference for sons and the country’s decades under a repressive one-child policy.

Now researchers in the United States and China think they might have found many — or even most — of them, and argue they might not have been killed after all.
