"The use of ultrasound equipment to determine the sex of an unborn child - introduced to India in 1979 - has now spread to every district in the country. The study found it played a crucial role in thetermination of an estimated 10 million female fetuses in the two decades leading up to 1998, and 5 million since 1994, the year the practice was banned. Few doctors in regular clinics offer the service openly, but activists estimate that sex-selection is a $100 million business in India, largely through mobile sex-selection clinics that can drive into almost any village or neighborhood. The practice is common among all religious groups - Hindus, Sikhs, Jains, Muslims, and Christians - but appears to be most common among educated women, a fact that befuddles public health officials and women's rights activists alike."
