Argentina has a racially and ethnically diverse population. The territory of what today is Argentina was first inhabited by numerous indigenous peoples. The first white settlers came during the period of Spanish colonization, beginning in the 16th century. The Spaniards imported African slaves, who would go on to become the first Afro-Argentines. Following independence from Spain in the 19th century and well into the 20th century, numerous migration waves took place, with Argentina being the second most popular destination for migrants in the early 20th century, after the United States. Most of these migrants came from Europe.
Most modern-day Argentines are descendants of these 19th and 20th century immigrants, with about 97% of the population being of full or partial European ancestry, while an estimated 31% or 56% have some indigenous or mestizo ancestry, and 5% or 9% have some African or mulatto ancestry. In the 2010 census , some 955,032 Argentines (2.38% of the population) identified as indigenous or first-generation descendants of indigenous peoples, while 149,493 (0.37% of the population) identified as Afro-Argentine.
In addition, Argentines of Arab (mostly Syrian and Lebanese) descent constitute a significant minority, and the Jewish population is the largest in all Latin America and the sixth largest in the world.
Indigenous peoples continue to have significant populations in the country's north-west (Quechua, Diaguita, Kolla, Aymara); north-east (Guaraní, Mocoví, Toba, Wichí); and in the south or Patagonia (Mapuche, Tehuelche).
Asian peoples have increasing minorities in some Buenos Aires neighborhoods and are expanding to other large Argentine cities. More recent migratory flows have come from other Latin American countries, with Paraguayans, Bolivians, Peruvians and Venezuelans making up the bulk of Argentina's modern-day immigrant communities.

Europeans.
Neither official census data nor statistically significant studies exist on the precise amount or percentage of Argentines of European descent today. The Argentine government recognizes the different communities, but Argentina's National Institute of Statistics and Censuses (INDEC) does not conduct ethnic/racial censuses, nor includes questions about ethnicity. The Census conducted on 27 October 2010, did include questions on Indigenous peoples (complementing the survey performed in 2005) and on Afro-descendants.
Arrival of the European immigrants.
The number and composition of the population was stable until 1853, when the national government, after passing a constitution, started a campaign to attract European immigration to populate the country. This state policy lasted several decades. At first the number of immigrants was modest compared to other countries such as the United States (though the number of immigrants was steadily increasing as they moved to the rural areas to settle and to found "colonias" like those of Italian, German, Swiss, or French origin), but in the 1870s, due to the economic crisis in Europe, it started to increase, reaching an extremely high rate between 1890 and 1930. Unofficial records show that, during the 1860s, 160,000 immigrants arrived in Argentina, while in the 1880s the net number increased to 841,000, almost doubling the population of the country in that decade.
Between 1857 and 1950, 6,611,000 European immigrants arrived in Argentina, making it the country with the second biggest immigration wave in the world, only second to the United States with 27 million, and ahead of such other areas of new settlement such as Canada, Brazil, Australia, New Zealand, Costa Rica, Colombia, Venezuela, Mexico and Uruguay and permanently changing the ethnography of Argentina.
Immigrants arrived through the port of Buenos Aires and many stayed in the capital or within Buenos Aires Province and this still happens today. In 1895, immigrants accounted for 52% of the population in the capital, and 31% in the province of Buenos Aires (some provinces of the littoral, such as Santa Fe, had about 40%, and the Patagonian provinces had about 50%).
Waves of immigrants from European countries arrived in the late 19th and early 20th centuries. Over 30 percent of the country's population was born overseas by 1914, and half of the population in Buenos Aires and Rosario was foreign-born. Over 80% of the Argentine population, per the 1914 Census, were immigrants, their children or grandchildren.
The Hotel de Inmigrantes, built in 1906 to accommodate the 100,000 to 200,000 yearly arrivals at the Port of Buenos Aires, was made a National Historic Monument.
Italians.
Italian immigration to Argentina began in the 19th century, just after Argentina won its independence from Spain. 
Argentine culture has significant connections to Italian culture, in terms of language, customs and traditions.
Italians became firmly established throughout Argentina, with the greatest concentrations in the city of Buenos Aires, Buenos Aires Province, Santa Fe Province, Entre Ríos Province, Córdoba Province, Tucumán Province, La Pampa Province, and the nearby country of Uruguay.
There are many reasons for the Italian immigration to Argentina: Italy was enduring economic problems caused mainly by the unification of the Italian states into one nation. The country was impoverished, unemployment was rampant, certain areas were overpopulated, and Italy was subject to significant political turmoil. Italians saw in Argentina a chance to build for themselves a brand new life.
The Italian population in Argentina is the third largest in the world, and the second largest (after Brazil) outside of Italy, More than 20 million people (47% of Argentina's population according to Argentine government websites). Italians form a majority of the population of Argentina and neighboring Uruguay: up to two-thirds have some Italian background. Among Latin American countries, only Brazil has more people of Italian descent (28 million, approximately 15 percent of Brazil's total population).
Croats.
Croats number of 200,000 in Argentina, settling primarily in Buenos Aires, Santa Fe, Chaco, and Patagonia. At the turn of the 19th-20th centuries, there were over 133 settlements. Many Croatian Argentines can trace their ancestry to Dalmatia and the Croatian Littoral. Many Croats came after Nikola Mihanovich developed the merchant marine.
Germans.
German immigration to Argentina occurred during five main time periods: pre–1870, 1870–1914, 1918–1933, 1933–1940 and post–1945.
Argentina and Germany have long had close ties to each other. A flourishing trade developed between them as early as the German Unification, and Germany had a privileged position in the Argentine economy. Later, Argentina maintained a strong economic relationship with both Germany and Great Britain and supported them with supplies during World War I.
There are around 50,000 German descendants living in Buenos Aires. After the United States and Brazil, Argentina is among the nations with the largest number of German descendants in the world, together with Australia, Canada, South Africa and France. They arrived in the 19th century and then before and after World War II. Their arrival continued over an extended period, from the middle to end of the 19th century, until 1960 of the 20th century. Germans, Swiss, Belgian, Luxembourg and French people founded the Colony of Esperanza, establishing the first agricultural colony and then founding others.
The influence of their culture has also impacted Argentine cuisine; this trend is especially apparent in the field of desserts. The pastries known as facturas are Germanic in origin: croissants, known as medialunas ("half-moons", from German "Halbmond"), are the most popular of these, and can be found in two varieties: butter- and lard-based. Also German in origin are the "Berliner" known as bolas de Fraile ("friar's balls"), and the rolls called piononos.
The facturas were re-christened with local names given the difficult phonology of German, and usually Argentinized by the addition of a dulce de leche filling. That was also the case with the "Kreppel", called torta fritas in Argentina, which were introduced by German immigrants, and similarly with the "Achtzig Schlag" cake, translated as torta ochenta golpes. In addition, dishes like chucrut (sauerkraut) and many different kinds of sausage like bratwurst have made it into mainstream Argentine cuisine.
More than 7% of Argentines are of German descent. Over 2 million ethnic Germans in Argentina are of Volga German descent.
French.
French immigration has left a significant mark on Argentina, with a notable influence on the arts, culture, science and society of the country. Many emblematic buildings in cities like Buenos Aires, Rosario, and Córdoba were built following French Beaux Arts and neoclassical styles, such as the Argentine National Congress, the Metropolitan Cathedral, or the Central Bank building. In particular, landscape architect Carlos Thays, in his position as 1891 Director of Parks and Walkways, is largely responsible for planting thousands of trees, creating the Buenos Aires Botanical Garden and giving the city many of its parks and plazas that are sometimes compared to similar designs in Paris.
While Argentines of French descent make up a substantial percent of the Argentine population, they are less visible than other similarly sized ethnic groups. This is due to the high degree of assimilation and the lack of substantial French colonies throughout the country.
Spaniards.
Argentine elites diminished the Spanish culture from their culture in the newly independent country and created Argentine culture.
Between 1857 and 1940 more than 2 million Spanish people emigrated to Argentina, mostly from Galicia, Basque Country, Asturias, Cantabria in northern Spain, Catalonia in northeast Spain, and also from Andalusia in southern Spain.
Scandinavians.
Scandinavians arrived in Argentina around 1909. The first ones settled in the northeastern area and founded a city called Villa Svea (now called Oberá). It was composed of Swedes, Norwegians and Finns. Russians, Germans, English and Danish joined them before and after World War I and spread throughout the country.
Austrians.
Austrians settled throughout the country in the late 19th century.
Swiss.
Approximately 44,000 Swiss emigrated to Argentina until 1940, and settled mainly in the provinces of Córdoba and Santa Fe and, to a lesser extent, in Buenos Aires.
British.
Around 100,000 British immigrants arrived between 1857 and 1940. The British community founded solid institutions like the British Hospital in Buenos Aires, the "Herald" newspaper, prestigious bilingual schools and clubs as the Lawn Tennis Club and Hurlingham Club. British immigrants had a strong impact on the taste of Argentine sports through the development of football, polo, hockey, and rugby, among others.
Today, there are over 350,000 Argentines with ancestry from the British Isles.
Greeks.
There are about 30,000 to 50,000 Argentines of Greek descent. The first immigrants arrived at the end of the 18th century, while the bulk of immigration occurred during the first half of the 20th century. Many were Aromanians and Megleno-Romanians immigrating from Greece, who became adjusted to Argentine society because of the linguistic similarities between Eastern Romance and Spanish, as well as the Latin identity of Aromanians and Megleno-Romanians.
Albanians.
During the great immigration from Italians towards Argentina, there were also a lot of Arbereshe people. They became part of the great European immigration towards South America in the 19th century. Most Albanians who migrated to Argentina were Arbëreshë from Southern Italy.
Bulgarians.
Bulgarian immigration in Argentina began intensively in the 1920s and had a second boom period between 1937 and 1938. Most of them were farmers from the northern regions of Bulgaria. Most settled in the province of Chaco.
Czechs.
The Czechs were also part of the great immigration of the early 20th century. Most of their descendants live in the provinces of Chaco and Mendoza, in the country.
Irish.
The Irish emigrated to Argentina in the 19th century, between 1830 and 1875. They extended throughout the country, especially in the provinces of Santa Fe, Entre Rios and Córdoba. The modern Irish-Argentine community is estimated to be between 500,000 and 1,000,000. Argentina is the home of the fifth largest Irish community in the world.
Lithuanians.
after the First World War, between 1925 and 1930, and settled mainly in Buenos Aires, Berisso and Rosario.
Luxembourgers.
From 1888 to 1890, the Grand Duchy of Luxembourg was literally overwhelmed by a transatlantic migration wave, the so-called "Argentinienfieber", literally ‘Argentine fever’. In less than two years, more than one thousand Luxembourgers - representing 0.5 per cent of the entire population - decided to emigrate to Argentina.
Dutch.
The first organized immigration from the Netherlands occurred in 1889, when immigrants came from the area of Friesland. A second immigration took place around 1924. Most of them settled in Mar del
