However, the 1914 National Census revealed that around 80% of the national population were either European immigrants, their children or grandchildren. Among the remaining 20 percent (those descended from the population residing locally before this immigrant wave took shape in the 1870s), around a third were white. European immigration continued to account for over half the nation's population growth during the 1920s, and was again significant (albeit in a smaller wave) following World War II. It is estimated that Argentina received over 6 million European immigrants during the period 1857–1940.
