Dear Y.....
I do not agree with your categorization in the poll. First of all, Saudi Arabia is not in South Asia (that would be caucasian of middle eastern origin), nor your spelling is correct when it comes to Chileans or Colombians in the hispanic section. Moreover, the hispanic characterization is too broad.
Do a new poll where people could vote according to their country of origin. I am pretty sure is going to be very interesting, or at least include an other section where the voter could include that last piece of information.
Thanks
