Wikipedia has Mexico as one of the countries with most European decends, but honestly seems to high some other sources has Mexico as low 9% and that seems very low to me as well.

Lived In Mexico 20 years before I moved to the United States, and full European Mexicans aren't rare at all.
Is Wikipedia considering admixtures as 55% 60-70% & 70-80% as white?
