Demographics of Chile

I generally like your edits which are better sourced and more clear except for a few things:
You make it seem that lower class Chileans are mainly Indian, Middle Class are half half and higher class are mainly Spanish. This is not the case. Middle class Chileans are of mainly Spanish origin as are most those of lower class. I would like to see a source for the figure of 43% Indian admixture. Your language also denotes and intent to maximise the Indian origin of Chileans? Why is this?
