Unnatural Selection: Choosing Boys Over Girls, and the Consequences of a World Full of Men

Publishers Weekly

This extraordinary debut from Mara Hvistendahl, award-winning writer and correspondent for Science magazine, reveals the fascinating yet terrifying state of sex ratio imbalance. Drawing on research and her experience living in China, where the one-child policy still holds sway, Hvistendahl nimbly shifts between quantitative data and ethnographic reports. As brides or prostitutes, women in Asia, Eastern Europe, and the Middle East are still treated as a commodity. With an estimated 160 million females missing from the Asian population, there is the added crisis of "surplus men," thus causing "rampant demographic masculinization," and carrying with it the possibility of increased social instability and violence. By analyzing sociological trends between affluence and birth, especially amidst the current boom of China and India, and providing sound historical overviews of how cultural traditions and governmental policies have evolved, Hvistendahl reveals the true extent of entrenched ideologies and moreover, the lack of intervention from oblivious officials. Her exposé on prenatal sex selection brims with bold judgments that shed light on a culturally sensitive issue. A definitive text on demographic change and its startling consequences that is both thorough and thoroughly engaging.

A hard-hitting, eye-opening study that not only paints a dire future of a world without girls but traces the West's role in propagating sex selection.

In her debut, Beijing-based Science correspondent Hvistendahl delves deeply into the causes of the vanishing of girls in Asia and Eastern Europe and looks beyond the traditional explanation of infanticide and abandonment. In fact, girls are simply not being born—demographers calculate that 163 million potential girls have been eliminated in Asia alone through ultrasound and abortion, the technological advancements of the West. A natural sex ratio at birth is 100 girls to 105 boys--nature compensates for the fact that more boys tend to die young due to dangerous behavior, wars, exhaustion, etc. Even a slight deviation from this natural balance toward boys can have enormous repercussions in a society, leaving a surplus of males unable to find mates, introducing instability, violence and the possibility of extinction. Astoundingly, the sex ratio in China is 121 boys to girls, in India 112. The skewed gender imbalance has also swept Vietnam, the Caucasus and the Balkans—all developing countries where the status of women is supposed to have improved as the countries got richer. Yet traditional beliefs—boys take care of their parents and the ancestral graves, girls need a large dowry for marriage and are a burden—are deeply ingrained in these societies, even still among Asian immigrants in America, whose sex ratio is also skewed toward boys. By the mid-1980s, the high-quality second trimester ultrasound arrived; despite laws passed proscribing its use in sex selection in China, India and elsewhere, doctors capitulated to patients' needs—and money. Western doomsayers and scientists set up the alarm by the late 1960s about world overpopulation, and naively (or sinisterly, as the author hints) endorsed sex selection even then as an effective form of birth control, setting the groundwork for future crisis.

Hvistendahl's important, even-handed exposé considers all sides of the argument and deserves careful attention and study.
