Title: Demographics of Mexico
Content:   White Mexicans are Mexican citizens of full or majority European descent. This ethnic group contrasts with the Afro-Mexican and Indigenous Mexican groups in the fact that phenotype (hair color, skin color etc.) is often used as the main criterion to delineate it. Spaniards and other Europeans began arriving in Mexico during the Spanish conquest of the Aztec Empire and continued immigrating to the country during colonial and independent Mexico. According to 20th- and 21st-century academics, large scale intermixing between the European immigrants and the native Indigenous peoples would produce a Mestizo group which would become the overwhelming majority of Mexico's population by the time of

Content:  Geography and Statistics Institute, as of 2017 Mexico has 123.5 million inhabitants making it the most populous Spanish-speaking country in the world. Between 2005 and 2010, the Mexican population grew at an average of 1.70% per year, up from 1.16% per year between 2000 and 2005. Even though Mexico is a very ethnically diverse country, research about ethnicity has largely been a forgotten field, in consequence of the post-revolutionary efforts of Mexico's government to unify all non-indigenous Mexicans under a single ethnic identity (that of the "Mestizo"). As a result, since 1930 the only explicit ethnic classification that has been included in Mexican censuses has been that of "Indigenous peoples". Even then, across the years the government has used different criteria to count

It is not until very recently that the Mexican government began conducting surveys that consider other ethnic groups that live in the country such as Afro-Mexicans who amount to 2% of Mexico's population or White Mexicans who amount to 47% of Mexico's population (with the criteria being based on appearance rather than on self-declared ancestry). Less numerous groups in Mexico such as Asians and Middle Easterners are also accounted for, with numbers of around 1% each. , it is estimated that 1.2 million foreigners have settled in the country, up from nearly 1 million in 2010.

It is also observed that when asked directly about their ethno-racial identification, many Mexicans nowadays do not identify as Mestizos, would not agree to be labeled as such, and that "static" ethnoracial labels such as "White" or "Indian" are far more prominent in contemporary Mexican society than the "Mestizo" one is, whose use is mostly limited to intellectual circles, a result of the label's constantly-changing and subjective definition. The total percentage 
Title: Mexicans
Content:  Mexicans (mexicanos) are the citizens of Mexico. The most spoken language by Mexicans is Mexican Spanish, but some may also speak languages from 68 different Indigenous linguistic groups and other languages brought to Mexico by recent immigration or learned by Mexican immigrants residing in other nations. In 2015, 21.5% of Mexico's population self-identified as being Indigenous. There are about 12 million Mexican nationals residing outside Mexico, with about 11.7 million living in the United States. The larger Mexican diaspora can also include individuals that trace ancestry to Mexico and self-identify as Mexican yet are not necessarily Mexican by citizenship, culture or language. The United States has the largest Mexican population after Mexico in the world at 37,186,361 (2019). The modern nation of Mexico achieved independence from the Spanish Empire in 1810; this began the process of forging a national identity that fused the cultural traits of Indigenous pre-Columbian origin with those of Spanish ancestry. This led to what has been termed "a peculiar form of multi-ethnic nationalism".
Title: Indigenous peoples of Mexico
Content:  2015, 25,694,928 people in Mexico self-identify as being indigenous of many different ethnic groups, which constitute 21.5% of Mexico's population. At the time of Spanish conquest in the late 15th century, the indigenous population of Mexico has been estimated at about 25 million, and has therefore only reached this figure again over 500 years later.  These modern figures however are language based, making numbers under reported, as it discounts Indigenous people who can only speak Spanish. Due to the extreme success of "mestizaje" nationalism in the post-revolutionary period in the early 20th century, the major period of political consolidation in Mexico, Indigenous people often report themselves as Mestizo and commonly forego their native heritage in favor of the national identity.
Title: Mexican Americans
Content:  Ethnically, Mexican Americans are a diverse population, including those of European ancestry, Indigenous ancestry, a mixture of both, African, East Asian, and Mexicans of Middle Eastern descent (mainly Lebanese). The Mexican population is majority Mestizo, which in colonial times meant to be a person of mixed heritage, particularly European and Native American. Nonetheless, the meaning of the word has changed through time, currently being used to refer to the segment of the Mexican population who does not speak Indigenous languages, thus in Mexico, the term "Mestizo" has become a cultural label rather than a racial one, it is vaguely defined and includes people who does not have Indigenous ancestry, people who does not

Such transformation of the word is not a casualty but the result of a concept known as "mestizaje", which was promoted by the post-revolutionary Mexican government in an effort to create a united Mexican ethno-cultural identity with no racial distinctions. It is because of this that sometimes the Mestizo population in Mexico is estimated to be as high as 93% of the Mexican population. Per the 2010 US Census, the majority (52.8%) of Mexican Americans identified as being white. The remainder identified themselves as being of "some other race" (39.5%), "two or more races" (5.0%), Native American (1.4%), Black (0.9%), and Asian / Pacific

Content:  Due to the complex history of Mexicans occupying the United States, it is difficult to comprise one encompassing definition of Mexican American. Generally, a Mexican American is a person who was born in the United States and is of Mexican descent. However, not all people born in the United States and are of Mexican heritage identify as such. Other Mexican heritage identities include: Latino, Chicano, Mexican, and Hispanic. Latinos/as are a pan-ethnic group in the United States who are steadily growing and who come from different countries in Latin America including Mexico, Honduras, Puerto Rico, Peru, and Brazil. As of July 1, 2015, the Latino/a population of the United States is the nation’s largest racial/ethnic minority group, constituting 17.6 percent of the total population. At two thirds of the Latino/a ethnic category, Mexicans are by far the largest national origin group.

This segment of the population "could very well 're-Indianze' itself" and in many communities throughout Mexico "such processes of re-Indianization are already well under way." In 2000, the ethnic composition of Mexico was recorded as 18% Amerindian, 10.5% of which openly identified as detribalized. There is also evidence that increasing numbers of the detribalized Mexican population may be openly identifying as Indigenous, given the rapid increase in population size in recent national census figures.
