Mexico’s population is composed of many ethnic groups, including Indigenous peoples, who account for less than one-tenth of the total. Generally speaking, the mixture of Indigenous and European peoples has produced the largest segment of the population today—mestizos, who account for more than three-fifths of the total—via a complex blending of ethnic traditions and perceived ancestry. Mexicans of European heritage (“whites”) are a significant component of the other ethnic groups who constitute the remainder of the population.
