Fewer Asian women marrying - trend must be growing in India too?

This Economist article says China and India are not visibly affected by the trend of fewer women choosing to marry and have children in Asia. But I think it depends on which class you're looking at. It seems that a growing number of career-minded urban middle class women are single. Surprisingly it says there will be 60m (million?) more men than women in China and India by 2050!
