India will have 20% more men than women in the next two decades, thanks to sex-selective abortion and craze for male child in some states, according to a new study. Conducted by Dr Therese Hesketh and co-authors from the UCL Centre for International Health and Development, London, and published in the Canadian Medical Association Journal, the study says easy access to sex-selective abortions, has led to significant imbalances in the male/ female population in China, India and South Korea. Earlier, studies have said 5-7 lakh girls a year or 2,000 girls go missing in India daily due to female foeticide. In families, where one girl child already exists, the chances of a second girl being born are as low as 54%. In a family with two female children, the chances of third girl being born is as low as 20%.
