[18][19] Argentina is a multiethnic society, home to people of various ethnic, racial, religious, denomination, and national origins, with the majority of the population made up of Old World immigrants and their descendants.

[23][24] Argentina is a multiethnic society, which means that it is home to people of many different ethnic, racial, religious, and denominational backgrounds.

[28][29] Argentines descend mostly from Spaniards, Italians, Native Americans and to a lesser extent from French, Germans, East Asians, and others.

Immigration of recent decades includes mainly Paraguayans, Bolivians, Peruvians, and Brazilians, among other Latin Americans, Eastern Europeans, Africans, Arabs, and Asians.

[26]The average is Castizo (with Spanish and Italian ancestry): Large comprehensive studies across Argentina's many regions in order to characterize the genetic admixture have been lacking.

A team led by Daniel Corach conducted a study in 2010, analyzing 246 samples from eight provinces and three different regions of the country.

[41] Several studies found out that the European ancestry in Argentina comes mainly from the Iberian Peninsula and Italy with a much lower contribution from Central and Northern Europe.

In one of the most comprehensive genetic studies involving the population of Argentina, 441 Argentines from across the North East, Salta, Chubut and Buenos Aires (especially the urban conglomeration of Buenos Aires) of the country, it was observed that the sample population comprised on average of 65% European, followed by 31% Amerindian, and finally 4% of African ancestry; however, this study was unweighted and meant to be a representation of the diversity of Argentine DNA rather than a demonstration of the average ethnic composition of the country.

The first Argentines of East Asian descent were a small group of Japanese immigrants, mainly from the Okinawa prefecture, which came in the period between the early and mid 20th century.

Primarily living in their own neighbourhoods in Buenos Aires, many currently own their own businesses of varying sizes – largely textiles, grocery stores, and buffet-style restaurants.

[72] Today there is still a notable Afro-Argentine community in the Buenos Aires districts of San Telmo and La Boca.

[73] Today, Cape Verdeans constitute one of the largest African immigrant communities, numbering over 15,000; they mainly live in port cities in Buenos Aires Province, such as Ensenada and Dock Sud.

[79] A high percentage of Argentines are proficient in the English language since its teaching is included in educational establishments as early as kindergarten.

According to CONICET survey on creeds, about 76.5% of Argentines are Roman Catholic, 11.3% religiously indifferent, 9% Protestant (with 7.9% in Pentecostal denominations), 1.2% Jehovah's Witnesses, and 0.9% Mormons.

The first wave of emigration occurred during the military dictatorship between 1976 and 1983, principally to Spain, the United States, Mexico and Venezuela.

During the 1990s, due to the abolition of visas between Argentina and the United States, thousands of Argentines emigrated to North America.

The most popular immigration destinations in the Americas are: the United States and Brazil, and to a lesser degree, mostly to (Uruguay and Canada): Chile, Paraguay and Bolivia, while other communities settled in Venezuela, Peru, Colombia, Ecuador and Costa Rica.
