“Without fanfare, something remarkable has happened. The noxious practice of aborting girls simply for being girls has become dramatically less common. It first became widespread in the late 1980s, as cheap ultrasound machines made it easy to determine the sex of a fetus. Parents who were desperate for a boy but did not want a large family—or, in China, were not allowed one—started routinely terminating females. Globally, among babies born in 2000, a staggering 1.6m girls were missing from the number you would expect, given the natural sex ratio at birth. This year that number is likely to be 200,000—and it is still falling.

The fading of boy preference in regions where it was strongest has been astonishingly rapid. The natural ratio is about 105 boy babies for every 100 girls; because boys are slightly more likely to die young, this leads to rough parity at reproductive age. The sex ratio at birth, once wildly skewed across Asia, has become more even. In China it fell from a peak of 117.8 boys per 100 girls in 2006 to 109.8 last year, and in India from 109.6 in 2010 to 106.8. In South Korea it is now completely back to normal, having been a shocking 115.7 in 1990.”
