"In the south of India, they educated girls. Three things came together in southern India that are unbelievably coincidental. There, the local Maharajas believed in education for everybody. The Syrian Catholic Church built schools for boys and girls. And then the Communist party, which took over politics for a period of time, had very strong social policies that benefited women. As a result, girls got into school. It was the first part of the country where towns could claim to be 100 percent literate. And so there, you're going to have a sex ratio at birth that's normal."
