I am a Hindu living in Louisiana.  Hindus can refer to geographical, cultural and religious identifiers
That must be interesting! Are there many Hindus living in the southern US?
I do not know many but there are references to the land of the Indus as far back as ancient Greek
I live near Toronto, Canada and there is a very large population of people who identify as Hindu. What a lovely culture. 
Ye, it is.  Originally, Hindu was a cultural identifier fr people whi lived in the Indian sub continent.
I wonder what porportion of India is Hindu? I wish I knew more about this culture. 
I do not kniw.  But by the 16th century, the term began to refer to all residents of India who were not Muslims or Turkic.
