How many woman in India?

Answer 1

Estimated at 572 million in 2011.

The interesting/scary part is that there are approximately 46 million more males than females (1.08 males to every female). This will likely cause huge social problems in years to come as many men will not be able to find brides and marry.

Its alledged that another significant problem is female infanticide (the killing of female babies) as it is seen to be a burden to have a female child.
