 Made right after the consummation of the Mexican revolution, the social context in which this census was conducted makes it particularly unique, as the government of the time was in the process of rebuilding the country and was looking to unite all Mexicans in a single national identity.The 1921 census' final results in regards to race, which assert that 59.3% of the Mexican population self-identified as Mestizo, 29.1% as Indigenous, and only 9.8% as White, were then essential in cementing the "mestizaje" ideology (which asserts that the Mexican population as a whole is product of the admixture of all races), which shaped Mexican identity and culture through the 20th century and remains prominent nowadays, with extraofficial international publications such as "The World Factbook" and "Encyclopædia Britannica" using the 1921 census as a reference to estimate Mexico's racial composition up to this day.Nonetheless in recent times, the census' results have been subjected to scrutiny by historians, academics and social activists alike, who assert that such drastic alterations on demographic trends with respect to the 1793 census are impossible and cite, among other statistics, the relatively low frequency of marriages between people of different continental ancestries in colonial and early independent Mexico.
