Main origins of migrants to the United States, 1820-2010 

This graph shows how thirteen of the original nationalities making up the melting pot of United States permanent residents have evolved over two centuries. Several waves of migration are evident: first it was European, from the mid-19th to the early-20th century (Germans, Irish, English, Italians and Russians), then an opening-up to the rest of the world in the late 20th century (Asia and Latin America – with the greatest numbers – and Africa –with the fewest).
