Big sex bias in populations of such countries as China and India have been observed for many years and isn't surprising any more. However, social and cultural mechanisms accounting for this phenomenon are more complicated than one would assume. What's more it's not only restricted to these major asian countries but can be observed among all continents and many cultural traditions. Nicolas Eberstadt, the author of The Global War Against Baby Grils in The New Atlantis journal provides a very deep and elegant in terms of data presentation and analysis insight into this tremendous discrimination of females worldwide. Definitely, MUST READ.
