Mestizo (/mɛˈstiːzoʊ, mɪ-/;^[1] Spanish: [mesˈtiso] (listen)) or mestiza is a term historically used in Spain, Spanish America and the Philippines that originally referred to a person of combined European and Indigenous American descent, regardless of where the person was born. The term was used as an ethnic/racial category for mixed-race castas that evolved during the Spanish Empire. Although broadly speaking, Mestizo means someone of mixed European/indigenous heritage, and usually for someone considered a plebeian, the term did not have a fixed meaning in the colonial period. It was a formal label for individuals in official documentation, such as censuses, parish registers, Inquisition trials, and other matters. Individuals were labeled by priests and royal officials as mestizos, but the term was also used for self identification.^[2]

In the modern era, particularly in Spanish America, mestizo has become more of a cultural term, with culturally mainstream Latin Americans regarded as, or termed "mestizos" regardless of their actual ancestry and with the term Indian being reserved exclusively for people who have maintained a separate indigenous ethnic identity, language, tribal affiliation, etc.

The term mestizaje – taking as its root mestizo or mixed – is the modern Spanish word coined in the twentieth century for race mixture or miscegenation, the general process of mixing ancestries.^[3]

To avoid confusion with the original usage of the term mestizo, mixed people started to be referred to collectively as castas. In some Latin American countries, such as Mexico, the concept of the mestizo became central to the formation of a new independent identity that was neither wholly Spanish nor wholly indigenous, and the word mestizo acquired its current meaning, it being used by the government to refer to all Mexicans who do not speak indigenous languages,^[4][5] including people of complete European or indigenous descent as well as Asians and Africans.^[6]

The Portuguese cognate, mestiço, historically referred to any mixture of Portuguese and local populations in the Portuguese colonies. In colonial Brazil most of the non-enslaved population was initially mestiço de indio, i.e. mixed Portuguese and native Brazilian. There was no descent-based casta system, and children of upper class Portuguese landlord males and enslaved females would enjoy privileges higher than the ones given to the lower classes, such as formal education, though such cases were not so common and they tended to not inherit property, generally given to the children of free women, who tended to be legitimate offspring in cases of concubinage (also a common practice, inherited from Amerindian and African customs).

In the Philippines, which was a colony of Spain, the term mestizo came to refer to a Filipino with any foreign ancestry, and usually shortened as Tisoy.

In Indonesia, the term mestizo refers to ethnicity which is a mixture of Europeans and native Indonesians. They are called as Indo people.

In Ontario and western Canada, the Métis people are a distinct community composed of the descendants of Europeans (usually French or Scottish, sometimes English) involved in the fur trade and Canadian First Nations peoples (especially Cree and Anishinaabe; it does not include people of mixed European and Inuit ancestry). As used in Quebec, however, the term refers to anyone of mixed European (usually French) and First Nations ancestry.

The Spanish word mestizo is from Latin mixticius, meaning mixed.^[7][8] Its usage has been documented as early as 1275, to refer to the offspring of an Egyptian/Afro/Hamite and a Semite/Afro Asiatic.^[9] This term was first documented in English in 1582.^[10]

In the United States, Canada and other English-speaking countries and cultures, mestizo, as a loanword from Spanish, is used to mean a person of mixed European and American Indian descent exclusively, generally with connection to a Latin American culture or of Latin American descent, a concept much stricter than that found in Romance languages (especially Portuguese, possessing terms that are not cognate with mestizo for such admixture, and thus the concept of mestiço is not seen as particularly connected with Amerindian ancestry at all). It is related to the particular racial identity of historical Amerindian-descended Hispanic and Latino American communities in an American context.

In English-speaking Canada, Canadian Métis (with upper-case), as a loanword from French, refers to persons of mixed French and Indigenous ancestry. French-speaking Canadians, when using the word métis, are referring to Canadian Métis ethnicity, and all persons of mixed Amerindian and European ancestry, rather than the broader concept of mixed people in general (métis with lowercase), present in all other French-speaking countries, as would speakers of Spanish; the usual term to refer to mixed-ethnicity people in general is thus "mulâtre", which is considered elsewhere pejorative. In the United States, Métis Americans and Mestizo Americans are two distinct racial and ethno-racial identities, as reflected in the use of French and Spanish loanwords, respectively.

In the Philippines, the word mestizo usually refers to a Filipino with combined Indigenous and European ancestry, but occasionally it will be used for a Filipino with apparent Chinese ancestry, who will also be referred to as 'chinito'. The latter was officially listed as a "mestizo de sangley" in birth records of the 19th century, with 'sangley' as a reference to the Hokkienese word for business, 'seng-li'.

In the Portuguese-speaking world, the contemporary sense has been the closest to the historical usage from the Middle Ages, because of important linguistic differences, so that mestiço (mixed, mixed-ethnicity, miscegenation, etc.) is separated altogether from pardo (any kind of brown people) and caboclo (brown people originally of European–Amerindian admixture or assimilated Amerindians), in which mestiços can be also fully African or East Asian in their full definition (thus not brown) and one does not need to be a mestiço to be a part of the latter two categories.

In Brazil specifically, at least in modern times all non-Indigenous people are part of a single ethnicity (os brasileiros; lines between ethnic groups are historically fluid), the mestiço (Portuguese pronunciation: [meʃˈt(ʃ)isu], [miʃˈt(ʃ)isu]) group is by far the largest among the free people since the earliest decades of the colony. As explained above, the concept of mestiço should not in any way be confused with the mestizo as used in either the Spanish-speaking world or the English-speaking one, as it relates no special relation to being of Amerindian extraction, and also should not be confused with pardo, literally "brown people" (there are mestiços among all major groups of the country, Indigenous, Asian, pardo and African, and they are likely the majority in the three latter ones).

In Saint Barthélemy, the term mestizo refers to people of mixed European (usually French) and East Asian ancestry.^[11]

Mestizo (Spanish: [mesˈtiθo] or [mesˈtiso]), mestiço (Portuguese: [mɨʃˈtisu], [mesˈt(ʃ)isu] or [miʃˈt(ʃ)isu]), métis (French: [meˈtis]), mestís (Catalan: [məsˈtis]), Mischling (German: [mɪʃˈlɪŋɡ]), meticcio (Italian: [meˈtittʃo]), mestiezen (Dutch: [mɛsˈtizə(n)]), mestee (Middle English: [məsˈtiː]), and mixed (English) are all cognates of the Latin word mixticius.

In the Spanish colonial period, the Spanish developed a complex set of racial terms and ways to describe difference. Although this has been conceived of as a "system," and often called the sistema de castas or sociedad de castas, archival research shows that racial labels were not fixed throughout a person's life. Artwork created mainly in eighteenth-century Mexico, "casta paintings," show groupings of racial types in hierarchical order, which has influenced the way that modern scholars have conceived of difference in Spanish America.^[12]

There were three main categories of ethnicity during the initial period of colonization of the Americas by the Spanish: European white or Spaniard (español), Amerindian (indio), and African (negro). Throughout the territories of Spanish Empire in the Americas, ways of differentiating individuals in a racial hierarchy, often called in the modern era the sistema de castas or the sociedad de castas developed where society was divided based on color, calidad (status) and other factors. The main divisions were as follows:

In theory, and as depicted in eighteenth-century Mexican casta paintings, español status could also be restored to the offspring of a Castizo/a [mixed Spanish - Mestizo] and an Español/a.^[13]

Racial labels in a set of eighteenth-century Mexican casta paintings by Miguel Cabrera:

In the early colonial period, the offspring of Españoles and Indias were raised either in the Hispanic world, if the father recognized the offspring as his natural child; or the child was raised in the indigenous world of the mother if he did not. As early as 1533, Charles V mandated the high court (Audiencia) to take the children of Spanish men and indigenous women from their mothers and educate them in the Spanish sphere.^[14] This mixed group born out of Christian wedlock increased in numbers, generally living in their mother's indigenous communities. ^[14]

Mestizos were the first group in the colonial era to be designated as a separate category from European whites (Españoles) and enslaved African blacks (Negros) and were included in designation of "vagabonds" (vagabundos) in 1543 in Mexico. Although mestizos were often classified as castas, they had a higher standing than any mixed-race person since they did not have to pay tribute, the men could be ordained as priests, and they could be licensed to carry weapons, in contrast to negros, mulattoes, and other castas. Unlike blacks and mulattoes, mestizos had no enslaved ancestors.^[15] Intermarriage between Españoles and mestizos resulted in offspring designated castizos ("three-quarters white"), and the marriage of a castizo/a to an Español/a resulted in the restoration of Español/a status to the offspring. Don Alonso O’Crouley observed in Mexico (1774), "If the mixed-blood is the offspring of a Spaniard and an Indian, the stigma [of race mixture] disappears at the third step in descent because it is held as systematic that a Spaniard and an Indian produce a mestizo; a mestizo and a Spaniard, a castizo; and a castizo and a Spaniard, a Spaniard. The admixture of Indian blood should not indeed be regarded as a blemish, since the provisions  of law give the  Indian all  that he could wish for, and Philip II granted to mestizos the privilege of becoming priests. On this consideration is based the common estimation of  descent  from a  union of  Indian and European or creole Spaniard."^[16]  O’Crouley states that the same process of restoration of racial purity does not occur over generations for European-African offspring marrying whites. “From the union of a Spaniard and a Negro the mixed-blood  retains  the stigma for generations without losing the original quality of a mulato."^[17]

The Spanish colonial regime divided groups into two basic legal categories, the Republic of Indians (República de Indios) and the Republic of Spaniards (República de Españoles) comprised European whites (Españoles) and all other non-Indians. Indians were free vassals of the crown, whose commoners paid tribute while indigenous elites were considered nobles and tribute exempt, as were mestizos. Indians were nominally protected by the crown, with non-Indians -- mestizos, blacks, and mulattoes -- forbidden to live in indigenous communities. Mestizos and Indians in Mexico habitually held each other in mutual antipathy. This was particularly the case with commoner Indians against mestizos, some of whom infiltrated their communities and became part of the ruling elite. Spanish authorities turned a blind eye to the mestizos' presence, since they collected commoners' tribute for the crown and came to hold offices. They were useful intermediaries for the colonial state between the Republic of Spaniards and the Republic of Indians.^[18]

A person's legal racial classification in colonial Spanish America was closely tied to social status, wealth, culture and language use. Wealthy people paid to change or obscure their actual ancestry. Many indigenous people left their traditional villages and sought to be counted as mestizos to avoid tribute payments to the Spanish.^[19] Many indigenous people, and sometimes those with partial African descent, were classified as mestizo if they spoke Spanish and lived as mestizos.

In colonial Venezuela, pardo was more commonly used instead of mestizo. Pardo means being mixed without specifying which mixture;^[20] it was used to describe anyone born in the Americas whose ancestry was a mixture of European, Amerindian and African.^[21]

When the Mexican republic was established in 1824, legal racial categories ceased to exist. The production of casta paintings in New Spain ceased at the same juncture, after almost a century as a genre.

Because the term had taken on a myriad of meanings, the designation "mestizo" was removed from census counts in Mexico and is no longer in use.^[10]

The large majority of Mexicans can be classified as "Mestizos", meaning in modern Mexican usage that they identify fully neither with any indigenous culture nor with a particular non-Indigenous heritage, but rather identify as having cultural traits incorporating both indigenous and European elements. In Mexico, Mestizo has become a blanket term which not only refers to mixed Mexicans but includes all Mexican citizens who do not speak indigenous languages^[4] even Asian Mexicans and Afro-Mexicans.^[22]

By the deliberate efforts of post-revolutionary governments the "Mestizo identity" was constructed as the base of the modern Mexican national identity, through a process of cultural synthesis referred to as mestizaje ([mes.tiˈsa.xe]). Mexican politicians and reformers such as José Vasconcelos and Manuel Gamio were instrumental in building a Mexican national identity on the concept of "mestizaje" (the process of ethnic homogenization).^[23][24]

Cultural policies in early post-revolutionary Mexico were paternalistic towards the indigenous people, with efforts designed to "help" indigenous peoples achieve the same level of progress as the Mestizo society, eventually assimilating indigenous peoples completely to mainstream Mexican culture, working toward the goal of eventually solving the "Indian problem" by transforming indigenous communities into Mestizo communities.^[5]

Sometimes, particularly outside of Mexico, the word "mestizo" is used with the meaning of Mexican persons with mixed Indigenous and European blood. This usage does not conform to the Mexican social reality where a person of pure indigenous genetic heritage would be considered mestizo either by rejecting his indigenous culture or by not speaking an indigenous language,^[25] and a person with none or very low percentage of indigenous genetic heritage would be considered fully indigenous either by speaking an indigenous language or by identifying with a particular indigenous cultural heritage.^[6] In the Yucatán peninsula the word mestizo has a different meaning to the one used in the rest of Mexico, being used to refer to the Maya-speaking populations living in traditional communities, because during the caste war of the late 19th century those Maya who did not join the rebellion were classified as mestizos.^[25] In Chiapas, the term Ladino is used instead of mestizo.^[26]

Due to the extensiveness of the modern definition of Mestizo, various publications offer different estimations of this group, some try to use a biological, racial perspective and calculate the Mestizo population in contemporary Mexico as being around a half and two thirds of the population,^[27] while others use the culture-based definition, and estimate the percentage of Mestizos as high as 90%^[4] of the Mexican population, several others mix-up both due lack of knowledge in regards to the modern definition and assert that mixed ethnicity Mexicans are as much as 93% of Mexico's population.^[28] Paradoxically to its wide definition, the word Mestizo has long been dropped of popular Mexican vocabulary, with the word even having pejorative connotations,^[25] which further complicates attempts to quantify Mestizos via self-identification.

While for most of its history the concept of Mestizo and Mestizaje has been lauded by Mexico's intellectual circles, in recent times the concept has been target of criticism, with its detractors claiming that it delegitimizes the importance of ethnicity in Mexico under the idea of "(racism) not existing here (in Mexico), as everybody is Mestizo."^[29] In general, the authors conclude that Mexico introducing a real racial classification and accepting itself as a multicultural country opposed to a monolithic Mestizo country would bring benefits to the Mexican society as a whole.^[30]

A 2012 study published by the Journal of Human Genetics found that the Y-chromosome (paternal) ancestry of the average Mexican Mestizo was predominately European (64.9%), followed by Native American (30.8%), and African (4.2%). The European ancestry was more prevalent in the north and west (66.7–95%) and Native American ancestry increased in the centre and south-east (37–50%), the African ancestry was low and relatively homogeneous (0–8.8%).^[31] The states that participated in this study were Aguascalientes, Chiapas, Chihuahua, Durango, Guerrero, Jalisco, Oaxaca, Sinaloa, Veracruz and Yucatán.^[32]

A study of 104 Mestizos from Sonora, Yucatán, Guerrero, Zacatecas, Veracruz, and Guanajuato by Mexico's National Institute of Genomic Medicine, reported that Mestizo Mexicans are 58.96% European, 31.05% Native American, and 10.03% African. Sonora shows the highest European contribution (70.63%) and Guerrero the lowest (51.98%) which also has the highest Native American contribution (37.17%). African contribution ranges from 2.8% in Sonora to 11.13% in Veracruz. 80% of the Mexican population was classed as mestizo (defined as "being racially mixed in some degree").^[33]

In May 2009, the same institution (Mexico's National Institute of Genomic Medicine) issued a report on a genomic study of 300 Mestizos from those same states. The study found that the Mestizo population of these Mexican states were on average 55% of indigenous ancestry followed by 41.8% of European, 1.8% of African, and 1.2% of East Asian ancestry.^[34]

The study also noted that whereas Mestizo individuals from the southern state of Guerrero showed on average 66% of indigenous ancestry, those from the northern state of Sonora displayed about 61.6% European ancestry. The study found that there was an increase in indigenous ancestry as one traveled towards to the Southern states in Mexico, while the indigenous ancestry declined as one traveled to the Northern states in the country, such as Sonora.^[34]

The Ladino people are a mix of mestizo or Hispanicized peoples^[35] in Latin America, principally in Central America. The demonym Ladino is a Spanish word that derives from Latino. Ladino is an exonym invented of the colonial era to refer to those Spanish-speakers who were not colonial elites of Peninsulares, Criollos, or indigenous peoples.^[36]

As of 2012 most Costa Ricans are primarily of Spanish or mestizo ancestry with minorities of German, Nicaraguan, Italian, Jamaican, Colombian, other Central American and Greek ancestry.

European migrants used Costa Rica to get across the isthmus of Central America as well to reach the USA West Coast (California) in the late 19th century and until the 1910s (before the Panama Canal opened). Other ethnic groups known to live in Costa Rica include Venezuelans, Peruvian, Brazilians, Portuguese, Palestinians, Caribbeans, Turks, Armenians and Georgians.

Many of the first Spanish colonists in Costa Rica may have been Jewish converts to Christianity who were expelled from Spain in 1492 and fled to colonial backwaters to avoid the Inquisition.^[37] The first sizable group of self-identified Jews immigrated from Poland, beginning in 1929. From the 1930s to the early 1950s, journalistic and official anti-Semitic campaigns fueled harassment of Jews; however, by the 1950s and 1960s, the immigrants won greater acceptance. Most of the 3,500 Costa Rican Jews today are not highly observant, but they remain largely endogamous.^[38]

Costa Rica has four small minority groups: Mulattos, Afro, Amerindians and Asians. About 8% of the population is of African descent or Mulatto (mix of European and African) who are called Afro-Costa Ricans, English-speaking descendants of 19th century Afro Jamaican immigrant workers.

By the late twentieth century, allusions in textbooks and political discourse to "whiteness," or to Spain as the "mother country" of all Costa Ricans, were diminishing, replaced with a recognition of the multiplicity of peoples that make up the nation.^[39]

In Central America, intermarriage by European men with the Native American Indigenous Lenca, Cacaopera and Pipil women of what is now El Salvador happened almost immediately after the arrival of the European Spaniards led by Pedro de Alvarado. Other indigenous groups in the country such as Maya Poqomam people, Maya Ch'orti' people, Alaguilac, Xinca people, Mixe and Mangue language people became culturally extinct due to the Mestizo process or diseases brought by the Spaniards. Mestizo culture quickly became the most successful and dominant culture in El Salvador. The majority of Salvadorans in modern El Salvador identify themselves as 86.3% Mestizo roots.^[40]

In 1932, ruthless dictator Maximiliano Hernandez Martinez was responsible for La Matanza ("The Slaughter"), known as the 1932 Salvadoran peasant massacre in which the Native American indigenous people were murdered in an effort to wipe out the indigenous people in El Salvador during the 1932 Salvadoran peasant uprising. Indigenous peoples, mostly of Lenca, Cacaopera and Pipil descent are still present in El Salvador in several communities, conserving their languages, customs, and traditions.

There is a significant Arab population (of about 100,000), mostly from Palestine (especially from the area of Bethlehem), but also from Lebanon. Salvadorans of Palestinian descent numbered around 70,000 individuals, while Salvadorans of Lebanese descent is around 27,000. There is also a small community of Jews who came to El Salvador from France, Germany, Morocco, Tunisia, and Turkey. Many of these Arab groups naturally mixed and contributed into the modern Salvadoran Mestizo population.

Pardo is the term that was used in colonial El Salvador to describe a tri-racial Afro-Mestizo person of Indigenous, European, and African descent. El Salvador is the only country in Central America that does not have a significant African population due to many factors including El Salvador not having a Caribbean coast, and because of president Maximiliano Hernández Martínez, who passed racial laws to keep Afros and other peoples out of El Salvador, though Salvadorans with African ancestry, called Pardos, were already present in El Salvador, the majority are tri-racial Pardo Salvadorans who largely cluster with the Mestizo population. They have been mixed into and were naturally bred out by the general Mestizo population, which is a combination of a Mestizo majority and the minority of Pardo people, both of whom are racially mixed populations. A total of only 10,000 enslaved Africans were brought to El Salvador over the span of 75 years, starting around 1548, about 25 years after El Salvador's colonization. The enslaved Africans that were brought to El Salvador during the colonial times, eventually came to mix and merged into the much larger and vaster Mestizo mixed European Spanish/Native Indigenous population creating Pardo or Afromestizos who cluster with Mestizo people, contributing into the modern day Mestizo population in El Salvador, thus, there remains no significant extremes of African physiognomy among Salvadorans like there is in the other countries of Central America.

Today, Salvadorans who are racially European, especially Mediterranean, as well as Native American indigenous people in El Salvador who do not speak indigenous languages nor have an indigenous culture, also tri-racial Pardo Salvadorans, and Salvadoran of Arab descent, also identify themselves as culturally Salvadoran Mestizo by absorption.

The Ladino population in Guatemala is officially recognized as a distinct ethnic group, and the Ministry of Education of Guatemala uses the following definition:

Initially colonial Argentina and Uruguay had a predominately mestizo population like the rest of the Spanish colonies, but due to a flood of European migration in the 19th century and the repeated intermarriage with Europeans the mestizo population became a so-called castizo population. With more Europeans arriving in the early 20th century, the majority of these immigrants coming from Spain and Italy, the face of Argentina and Uruguay has overwhelmingly become European in culture and tradition. Because of this, the term mestizo has fallen into disuse. Currently, individuals who are considered Whites contributes to 85% of Argentina's population and 88% of Uruguay's population.^[42]

Northern Argentina still has a predominately mestizo population, especially in the provinces of Jujuy, Salta, Tucumán, Santiago del Estero, Catamarca, La Rioja, San Juan, Mendoza, Chaco, Formosa, Corrientes, Santa Fe and Misiones, where there is also a significant population of Indigenous peoples.^[33][43]

In Chile, from the time the Spanish soldiers with Pedro de Valdivia entered northern Chile, a process of 'mestizaje' began where Spaniards began to mate with the local bellicose Mapuche population of Amerindians to produce an overwhelmingly mestizo population during the first generation in all of the cities they founded. In Southern Chile, the Mapuche, were one of the only Amerindian tribes in the Americas that were in continuous conflict with the Spanish Empire and did not submit to a European power.

A public health book from the University of Chile states that 30% of the population is of White origin; mestizos are estimated to amount to a total of 65%, while Native Americans (Amerindians) comprise the remaining 5%. A genetic study by the same university showed that the average Chilean's genes are 60% European and 40% Amerindian.

Colombia whose land was named after explorer Christopher Columbus is the product of the interacting and mixing of the European conquistadors and colonist with the different Amerindian peoples of Colombia. Later the African element was introduced into the coastal parts of Colombia as enslaved people.

Over time Colombia has become a primarily Mestizo country due to limited immigration from Europe in the 19th and 20th centuries, with the minorities being: the Mulattoes and Pardos living primarily in the coastal areas; and pockets of Amerindians living around the rural areas and the Amazonian Basin regions of the country.

An extraofficial estimate considers that the 49% of the Colombian population is Mestizo or of mixed European and Amerindian ancestry. Approximately 37% is of European ancestry (predominantly Spanish, and a part of Italian, French, and German) and of Middle Eastern ancestry. 10.6% is of African ancestry. Indigenous Amerindians comprise 3.4% of the population. 0.01% of the population are Roma.^[44] The 2005 census reported that the "non-ethnic population", consisting of Europeans and mestizos (those of mixed European and Amerindian ancestry), constituted 86% of the national population.^[44]

During the colonial era, the majority of Ecuadorians were Amerindians and the minorities were the Spanish Conquistadors, who came with Francisco Pizarro and Sebastian de Benalcazar. With the passage of time these Spanish conquerors and succeeding Spanish colonists sired offspring with the local Amerindian population, since Spanish immigration did not initially include many White females to the colonies. In a couple of generations a predominately mestizo population emerged in Ecuador with a drastically declining Amerindian Population due to European diseases and wars.

Afro-Ecuadorians (Zambos and Mulattoes), who are a minority in the country, can be found mostly in the Esmeraldas Province, in the Valle del Chota of the Imbabura Province, and as small communities of Afro-Ecuadorians living along the coastal areas as minorities.

Mestizos are by far the largest of all the ethnic groups, and comprise 71.9% of the current population. The next 28% of the population is comprised by four ethnic groups with about 7% each, the Montubios, Afroecuadorian, Amerindian (Indigenous) and White.

During the reign of José Gaspar Rodríguez de Francia, the first consul of Paraguay from 1811 to 1840, he imposed a law that no Spaniard may intermarry with another Spaniard, and that they may only wed mestizos or Indians. This was introduced to eliminate any sense of racial superiority, and also to end the predominantly Spanish influence in Paraguay. De Francia himself was not a mestizo (although his paternal grandfather was Afro-Brazilian), but feared that racial superiority would create class division which would threaten his absolute rule.

As a result of this, today 90% of Paraguay's population are mestizo, and the main language is the native Guaraní, spoken by 60% of the population as a first language, with Spanish spoken as a first language by 40% of the population, and fluently spoken by 75%, making Paraguay one of the most bilingual countries in the world. Although it did not had the exposition to miscegenation as de Francia wanted, after the tremendous decline of male population as a result of the War of the Triple Alliance, European male worker émigrés mixed with the female mestizo population so as that pushed a middle class of mestizo background largely accepted as a configuration of the country.

According to Alberto Flores Galindo, "By the 1940 census, the last that utilized racial categories, mestizos were grouped with White, and the two constituted more than 53% of the population. Mestizos likely outnumbered Indians and were the largest population group."^[45]

Mestizos are the majority in Venezuela, accounting for 51.6% of the country's population. According to D'Ambrosio^[46] 57.1% of mestizos have mostly European characteristics, 28.5% have mostly African characteristics and 14.2% have mostly Amerindian characteristics.

Martín Cortés, son of the Spanish conquistador Hernán Cortés and of the Nahuatl–Maya indigenous Mexican interpreter Malinche, was one of the first documented mestizos to arrive in Spain. His first trip occurred in 1528, when he accompanied his father, Hernán Cortés, who sought to have him legitimized by the Pope.

There is also verified evidence of the grandchildren of Moctezuma II, Aztec emperor, whose royal descent the Spanish crown acknowledged, willingly having set foot on European soil. Among these descendants are the Counts of Miravalle, and the Dukes of Moctezuma de Tultengo, who became part of the Spanish peerage and left many descendants in Europe.^[47] The Counts of Miravalle, residing in Andalucía, Spain, demanded in 2003 that the government of Mexico recommence payment of the so-called 'Moctezuma pensions' it had cancelled in 1934.

The mestizo historian Inca Garcilaso de la Vega, son of Spanish conquistador Sebastián Garcilaso de la Vega and of the Inca princess Isabel Chimpo Oclloun arrived in Spain from Peru. He lived in the town of Montilla, Andalucía, where he died in 1616. The mestizo children of Francisco Pizarro were also military leaders because of their famous father. Starting in the early 19th and throughout the 1980s, France and Sweden saw the arrival of hundreds of Chileans, many of whom fled Chile during the dictatorial government of Augusto Pinochet.

In the Philippines, the word "mestizo"^[8] and usually shortened as Tisoy as a modern usage, today generally denotes Filipinos of mixed Austronesian and any non-native, usually White, ethnicity.

Mestizos in the Philippines are traditionally a blend of Austronesian, Chinese, Spanish, Southern European or Latin American ancestry and are primarily descendants of viajeros (sailors who plied the Manila-Acapulco Galleon route), soldados (soldiers) and negociantes (merchants who were primarily Spanish, Chinese, or themselves mestizos). Because of this, most mestizos in the Philippines are concentrated in the urban areas and large towns of the islands such as Manila, Iloilo, Zamboanga, Cebu and Vigan. In these provinces of the Philippines, many Spaniards and foreign merchants intermarried with the rich and landed Malayo‑Polynesian local nobilities. From these unions, a new cultural group was formed, the mestizo class.^[48] Their descendants emerged later to become an influential part of the colonial government, and of the Principalía,^[49] among whom were Manuel L. Quezon, the first President of the Commonwealth of the Philippines (1935–1944); and Marcelo Azcárraga Palmero who even became interim Prime Minister of Spain on August 8, 1897 until October 4 of that same year. Azcárraga also went on to become Prime Minister of Spain again in two more separate terms of office. In 1904, he was granted Knighthood in the very exclusive Spanish chilvalric Order of the Golden Fleece — the only mestizo recipient of this prestigious award.

More recent migrations and interracial marriages beginning in the 20th century resulted in a greater variety of racial admixture with White Americans and other Asians.

In Guam and Northern Mariana Islands, the term "mestizo" was borrowed from the Spanish language and was formerly used to identify people of mixed Pacific Islander and Spanish ancestry; however, as the United States gained control of these islands after the Spanish–American War in 1898, the term "Multiracial" replaced "Mestizo".

Mestizos/Multiracials currently form a small minority of the population. Because most Guamanians and Northern Mariana Islanders were also given Spanish surnames as part of the Spanish East Indies, persons of white American and other non-Spanish European descent with Spanish surnames may be mistaken as having such descent.

In Brazil, the word mestiço is used to describe individuals born from any mixture of different ethnicity, not specifying any relation to Amerindian or European descent whatsoever. The Mixed Ethnicty Day, or Mestizo Day (Dia do Mestiço), on June 27, is official event in States of Amazonas, Roraima e Paraíba and a holyday in two cities.

One of the most notorious group is the pardo (brown people), also informally known as moreno (tan skinned people; given its euphemism-like nature, it may be interpreted as offensive). They include mostly those of non-white skin color. Nevertheless, not all pardos are mestiços. For example, an Amerindian (initially and most often índio, often more formally indígena, rarely ameríndio, an East Indian (indiano)) or a Filipino may be initially described as pardo/parda (in opposition to branco, white, negro, Afro, and amarelo, yellow) if his or her ethnicity is unknown, and it is testified by the initial discovery reports of Portuguese navigators. In the same way, mestiço, a term used to describe anyone with any degree of miscegenation in one's blood line, may apply to all said groups (that in Portugal and its ex-colonies, always depended solely on phenotype, meaning a brown person may have a full sibling of all other basic phenotypes and thus ethnic groups).

Important pardo groups in Brazil are the caboclos (largely contemporary usage) or mamelucos (largely archaic usage), the mulatos, and the cafuzos. The first group is composed of the culturally assimilated Amerindians as well as the brown-skinned descendants or children of both white or moreno (swarthy) people of otherwise White phenotype and Amerindians. They are an important group in the Northern (Amazon Basin) region, but also relatively numerous on the Northeastern and Center-Western ones. Then, those, neither Afro- nor fair-skinned, whose origins come from the admixture between White or morenos and Afros or cafuzos. The last group is composed of descendants of Amerindians or caboclos and Afros or other cafuzos. Finally, those whose origins possess a notorious level of European ancestry and in which neither Amerindian nor African phenotypical traces are much more present than each other are sometimes known as juçaras.

There are, however, important groups who are mestiços but not necessarily pardos. People of East Asian and non-Asian descent combined are known as ainokos, from the Japanese "love (ai) child (ko)" (also used for all children of illegitimate birth. Mixed children are now largely referred to as "half" or hāfu), though often, for those without contact with the term, mestiço de [East Asian nationality/ethnicity] may also be used. Sararás differ from mulatos at being fair-skinned (rather than brown-skinned), and having non-straight blond or red hair.

Other people who are not brown (and thus not pardo), but also their phenotypes by anything other than skin, hair and eye color do not match white ones but rather those of people of color may be just referred to as mestiço, without specification to skin color with an identitarian connotation (there are the distinctions, though, of mestiço claro, for the fair-skinned ones, and mestiço moreno, for those of olive skin tones). In Brazilian censuses, those people may choose to identify mostly with branco (White) or pardo (brown) or leave the question on ethnic/color blank.

The mestiço are primarily of mixed European, native born indigenous Angolan or other indigenous African lineages. They tend to be Portuguese culturally and to have full Portuguese names.

Although they make up about two percent of the population, they are the socially elite and racially privileged group in the country. Historically, mestiços formed social and cultural allegiances with Portuguese colonists subsequently identifying with the Portuguese over and above their indigenous identities. Despite their loyalty, the ethnic group faced economic and political adversity at hands of the white population during times of economic hardship for whites. These actions lead to ostracizing Mestiços from their inherited economic benefits which sparked the group to take a new sociopolitical direction.

Across the 500 year Portuguese presence in the country, the Mestiço have retained their position of entitlement which is highly evident in the political, economic and cultural hierarchy in present-day Angola. Their phenotype range is broad with a number of members possessing physical characteristics that are close to others within the indigenous Afro non-mixed population. Since the Mestiços are generally better educated than the rest of the indigenous Afro population, they exercise influence in government disproportionate to their numbers.

1% of the population is of mixed African and Portuguese descent, Tamahaq, and Arabic genetic influence ignored.

A minority population of Mozambicans of mixed Bantu and Portuguese heritage.

Mestiços of São Tomé and Príncipe are descendants of Portuguese colonists and enslaved Africans brought to the islands during the early years of settlement from Benin, Gabon, the Republic of the Congo, the Democratic Republic of the Congo, and Angola (these people also are known as filhos da terra or "children of the land").

In Sri Lanka, the names mestiços (Portuguese for "mixed ethniicity") or casados ("married ones") were applied to people of mixed Portuguese and Sri Lankan (Sinhalese and Tamil) descent, starting in the 16th century.

A French Colonial empire in Canada, the Métis are regarded as an independent ethnic group. This community of descent consists of individuals descended from marriages of First Nation women, specifically Cree, Ojibway, and Saulteaux with Europeans, usually French, English, and Scottish laborers or merchants employed in the North American Fur Trade. Their history dates to the mid 17th century, and they have been recognized as a distinct people since the early 18th century.

Traditionally, the Métis spoke a mixed language called Michif (with various regional dialects). Michif (a phonetic spelling of the Métis pronunciation of "Métif", a variant of Métis) is also used as the name of the Métis people. The name is most commonly applied to descendants of communities in what is now southern Manitoba. The name is also applied to the descendants of similar communities in what are now Ontario, Quebec, Labrador, and the Northwest Territories, although these groups' histories are different from that of the western Métis. In Northern Manitoba some communities spoke Bungee, a combination of Gaelic, Orcadian, Cree, and Ojibwe. Bungee is now extinct.

Estimates of the number of Métis vary from 300,000 to 700,000 or more. In September 2002, the Métis people adopted a national definition of Métis for citizenship within the "Métis Nation." Based on this definition, it is estimated that there are 350,000 to 400,000 Métis Nation citizens in Canada, although many Métis classify anyone as Métis who can prove that an ancestor applied for money scrip or land scrip as part of nineteenth-century treaties with the Canadian government. However, Labrador, Quebec, and even some Acadian Métis communities are not accepted by the Métis National Council and are represented nationally by the "Congress of Aboriginal Peoples."

The Métis are recognized as Aboriginal, but not as a First Nation by the Canadian government and do not receive the same benefits granted to First Nation peoples. However, the 1982 amendments to the Canadian constitution recognize the Métis as an aboriginal people, and have enabled individual Métis to sue successfully for recognition of their traditional rights such as rights to hunt and trap. In 2003, a court ruling in Ontario found that the Métis deserve the same rights as other aboriginal communities in Canada.

In Saint Barthélemy, the term mestizo refers to people of mixed European (usually French) and East Asian ancestry.^[11]

The United States has a large mestizo population, as many Hispanic Americans of Mexican or Central American or South American descent are technically mestizo. However, the term "mestizo" is not used for official purposes, with Mexican Americans being classed in roughly equal proportions as "white" or "some other ethnicity" (see links), and the term "mestizo" is not in common popular use within the United States.

Many Mexican-Americans use the term Chicano, which has a strong connection with their Native heritage.

A 19th-century community of the Métis people of Canada, the Anglo-Métis, more commonly known as Countryborn, were children of fur traders; they typically had Orcadian, Scottish, or English fathers and Aboriginal mothers. Their first languages were generally those of their mothers: Cree, Saulteaux, Assiniboine, etc. and English. Some of their fathers spoke Gaelic or Scots, leading to the development of the dialect of English known as "Bungee".
