NS , not so sure . .
But Mexico is a largely Mestizo country (Mestizo=Caucasian plus Indio-admixture )
Already the first settlers there from Spain didn't do it like the Anglo settlers of North America ( USA / Canada ) and took people from back in Europe as settlers but took sons/daughters from the natives there . .
That's why today Meso/South-America is so mixed.
There might be unmixed Caucasian people still present there but Mexico is known for being largely Mestizo
