Between 1857 and 1950 Argentina was the country with the second biggest immigration wave in the world, at 6.6 million, second only to the United States in the numbers of immigrants received (27 million) and ahead of other areas of new settlement like Canada, Brazil and Australia. However, mass European immigration did not have the same impact in the whole country. According to the 1914 national census, 30% of Argentina's population was foreign-born, including 50% of the people in the city of Buenos Aires, but foreigners were only 2% in the provinces of Catamarca and La Rioja (North West region).
