In 1927, Ernest Hemingway published a collection of short stories titled Men Without Women.Today, less than a century later, it sums up the predicament of a rising proportion of mankind.
According to the United Nations, there are far more men than women on the planet. The gender gap is especially pronounced in Asia, where there are 100 million more guys than girls. This may come as a surprise to people in the Western world, where women outnumber men because—other things being equal—the mortality rate for women is lower than for men in all age groups. Nobel Prize–winning economist Amartya Sen calls it the mystery of Asia’s “missing women.”
The mystery is partly explicable in terms of economics. In many Asian societies, girls are less well looked after than boys because they are economically undervalued. The kind of domestic work they typically do is seen as less important than paid work done by men. And, of course, early marriage and minimal birth control together expose them to the risks of multiple pregnancies.
