The CIA and the US goverment historically have admitted that mexicans are white when they do the census.I 
 I am curious, the CIA fact book states that the USA is 81.7% white 12.9% black, 4.2% Asian, and 2% others? This adds up to about 100%, what happened to all the Mexicans, and Hispanics? Are they saying that ones a Mexican crosses over the border he or she becomes white? that makes no sense. At what percentage does a mestizo become white, 50%, 75%, or 90%. According to the U.S census if a Mexican marks Mexican on the U.S Census, he or she will be classified as white. This leads to my final question, shouldn’t then most Mexicans be classified white, according to the CIA? Finally, I have been to several parts in Mexico and I have noticed that many, or the majority of Mexicans in central Mexico look whiter than Italians, French and middle eastern, which are classified as white everywhere. A large percentage of the Argentinean population has Amerindian mixture, doesn't that make them Mestizo's? Any ways, we will never know for sure until a large genetic sample is taken. I agree with having a predominate 35-45%, if you look at the Aregentina demographics it states that 57% of the population has ameridian ancestory, but 85-97% of the population states that they are white? I am from Jalisco, I would have to say that most people I have seen look more white than Italians or Middle Easterns in the U.S.
