Finalist for the Pulitzer Prize A Slate Best Book of 2011 A Discover Magazine Best Book of 2011 Lianyungang, a booming port city, has China's most extreme gender ratio for children under four: 163 boys for every 100 girls.These numbers don't seem terribly grim, but in ten years, the skewed sex ratio will pose a colossal challenge.By the time those children reach adulthood, their generation will have twenty-four million more men than women. The prognosis for China's neighbours is no less bleak: Asia now has 163 million females "missing" from its population.Gender imbalance reaches far beyond Asia, affecting Georgia, Eastern Europe, and cities in the U.S. where there are significant immigrant populations. The world, therefore, is becoming increasingly male, and this mismatch is likely to create profound social upheaval. Historically, eras in which there have been an excess of men have produced periods of violent conflict and instability.Mara Hvistendahl has written a stunning, impeccably-researched book that does not flinch from examining not only the consequences of the misbegotten policies of sex selection but Western complicity with them.
