 Of all the ethnic groups that have been surveyed, Mestizos are notably absent, which is likely due the label's fluid and subjective definition, which complicates its precise quantification.However it can be safely assumed that Mestizos make up at least the remaining 30% unassessed percentage of Mexico's population with possibilities of increasing if the methodologies of the extant surveys are considered.As example the 2015 intercensal survey considered as Indigenous Mexicans and Afro-Mexicans altogether individuals who self-identified as "part Indigenous" or "part African" thus, said people technically would be Mestizos.
