Perhaps you have heard India described as a 'nation of villages'? 
This is very true of Hinduism as well so that website is educational but not a worldwide norm of what Hindus must believe. There are academic leaders but nothing comparable to the Vatican, so ideas and practices vary. Some Hindu village cultures consider any unmarried person to be equivalent with a young unmarried adult or a even a child. A childless couple is also accursed in almost every old time, eastern or western culture.

There is a reason for The Married Women's Property Act 1882 in England.  Nun's still complain about there lack of rights within the Church to this day.
