Female foeticide, or the killing of female fetuses, is a major issue in India. It is driven by social preferences for sons over daughters and enabled by technology like ultrasounds. This has led to unnatural increases in the male to female sex ratio, with 108.8 males for every 100 females according to the 2011 census. The government has tried to address this through acts banning sex-selective abortions, but enforcement has been a challenge due to social attitudes.
