It's heartbreaking to read about what sex bias in India in the 80s and 90s, and I'm sure that a preference for boys still exists today, although I'm also curious how the rates of abortion and infanticide have changed since Das Gupta's study. I know little about the situation in India but know a bit more about the East Asian countries - I wonder if the bias in India is also due to (among other things) the cultural expectation that sons are responsible for caring for their parents in old age? It was also interesting (but shocking) to read that the education level of women had little effect on the sex bias, and implied infanticide was occurring at such high rates despite there being no mandate (that I know of) akin to the One Child Policy in China, and therefore were probably entirely economical in decision.
