A nappy nit - when you say someone is a Mexican that refers to a person who is recognized as an individual who belongs to and is under the protection of the modern nation state of Mexico. The variety (or ethnicity) of peoples that this includes is mainly divided (socially constructed if you like) by Mexican's themselves.

Ethnic groups
Mexico’s population is composed of many ethnic groups, including indigenous American Indians (Amerindians), who account for more than one-sixth of the total, and Mexicans of European heritage (“whites”), who are nearly as numerous. Generally speaking, the mixture of indigenous and European peoples has produced the largest segment of the population today—mestizos, who account for nearly two-thirds of the total—via a complex blending of ethnic traditions and perceived ancestry. Although myths of “racial biology” have been discredited by social scientists, “racial identity” remains a powerful social construct in Mexico, as in the United States and elsewhere, and many Mexicans have referred to their heritage and raza (“race”) with a measure of pride—particularly on October 12, the Día de la Raza (“Race Day”)—whether they conceive of themselves as indigenous, mestizo, or European. Their identities as members of ethnic groups may be additionally complicated, given that ethnicity is a function of cultural patterns and traditions as varied as a group’s sense of linguistic, religious, and socioeconomic history.

It is interesting that the Encyclopedia Britannica article missed the important fact that there is a small minority of former slaves that live in Mexico.

From above link:
Afro-Mexicans are an ethnic group which exists in certain parts of Mexico such as the Costa Chica of Oaxaca and Guerrero, Veracruz and in some cities in northern Mexico. The existence of blacks in Mexico is unknown, denied or diminished in both Mexico and abroad for a number of reasons: their small numbers, heavy intermarriage with other ethnic groups and Mexico’s tradition of defining itself as a “mestizaje” or mixing. Mexico did have an active slave trade since the early colonial period but from the beginning, intermarriage and mixed race offspring created an elaborate caste system. This system broke down in the very late colonial period and after Independence the legal notion of race was eliminated. The creation of a national Mexican identity, especially after the Mexican Revolution, emphasized Mexico’s indigenous and European past actively or passively eliminating its African one from popular consciousness. Though, Mexico had a significant number of African slaves during colonial times, most of the African-descended population got absorbed into the larger Mestizo (European/indigenous) population through Miscegenation. Less than 1% of Mexico's population has significant African ancestry, and a large number of Afro-Mexicans are actually naturalized black immigrants from Africa and the Caribbean. The moderate numbers of blacks in the Mexican American population, is the result of unions between African Americans and Mexican Americans.
