Over 700 villages, all with a birth rate of about two births per 3 months, there might very well be 132 villages with no girls born, 140 villages with no boys born, and 428 villages with one boy and one girl born. It wouldn't be alarming at all.

But if these villages represent a contiguous area, then it is alarming. The article doesn't really give enough information to say anything about this really.

Data is from a single district, and then blocks. So blocks are contiguous. Analogous to say New York metro area, and then Brooklyn, Manhattan, Queens etc.
