Spanish Mexicans are Mexicans who identify as Spanish as a result of nationality or ancestry. Spanish immigration to Mexico began in the early 1500s and spans to the present day. The vast majority of Mexicans have at least partial Spanish ancestry; the Northern regions of Mexico have a higher prevalence of Spanish heritage.

About 85% (100 million) of Mexican population is of at least partial Spanish descent. According to 2020 Census, the Spanish in Mexico number about 20,763 Spaniards (born in Spain) and 144,553 Spanish nationals.

The largest population of Spanish descent are located in Mexico Valley, Puebla-Veracruz region, Bajío region, Guadalajara Valley, Altos de Jalisco, Northern region and Riviera Maya, where they make up the largest proportion of the Spanish population.

Large populations are found in the states like Mexico City, Mexico State, Veracruz, Puebla, Jalisco, Nuevo León, Aguascalientes, Durango, Guanajuato, Querétaro, and Chihuahua. Also, Northern Mexico is inhabited by millions of Spanish descendants.

Spanish  Brazilians are Brazilians who have full or partial Spanish ancestry.  Spanish immigration was the third largest among immigrant groups in Brazi. Brazilian censuses do not research “ethnic origins” or ancestry, which makes it very difficult to give accurate numbers of Brazilians of Spanish descent.

According to the estimates and surveys, there were 10 million people of Spanish  descent in Brazil.

The Brazilian states with significant Spanish  population are mainly Southeastern Brazil (particularly São Paulo and Rio de Janeiro).

Spanish Argentines are Argentines who have full or partial Spanish ancestry.  Between the 15th and 19th centuries, the Spanish Empire was the sole colonial power in the territories that became Argentina. Thus, before 1850, the vast majority of European settlers in Argentina were from Spain. A substantial Spanish descended Criollo population gradually built up in the new cities, while some mixed with the indigenous populations (Mestizos), with the Black African-descended slave population (Mulattoes) or with other European immigrants.

Since a great portion of the immigrants to Argentina before the mid-19th century were of Spanish descent, and a significant part of the late-19th century/early-20th century immigrants to Argentina were Spaniards, the large majority of Argentines are at least partly of Spanish ancestry.

According to the estimates and surveys, there were 20 million Spanish descendants (including those of mixed or partial Spanish descent)
