White Mexicans (Mexicanos blancos) are Mexicans who are considered or identify as white, typically due to their physical appearance and/or self-identification with their European ancestry. While the Mexican government does conduct ethnic censuses in which a Mexican has the option of identifying as "White" the results obtained from these censuses are not published. What Mexico's government publishes instead is the percentage of "light-skinned Mexicans" there are in the country, with it being 47% in 2010 and 49% in 2017. Due to its less directly racial undertones, the term "Light-skinned Mexican" has been favored by the government and media outlets over "White Mexican" as the go-to choice to refer to the segment of Mexico's population who possess European physical traits when discussing different ethno-racial dynamics in Mexico's society. Nonetheless, sometimes "White Mexican" is used. Estimates of Mexico's white population differ greatly in both methodology and percentages given; unofficial sources such as the World Factbook and Encyclopædia Britannica, which use the 1921 census results as the base of their estimations, calculate the white Mexican population as between 9% to 20%-30% The results of the 1921 census, however, have been contested by various historians and deemed inaccurate similarly recent research has found that Mexicans in reality do not identify the way that sources such as The World Factbook state they do. Surveys that account for phenotypical traits and have performed actual field research suggest rather higher percentages: using the presence of blond hair as reference to classify a Mexican as white, the Metropolitan Autonomous University of Mexico calculated the percentage of said ethnic group within the institution at 23%. With a similar methodology, the American Sociological Association obtained a nationwide percentage of 18.8%.
