Through time, the immigration sources trace a clear path through the world. Starting in Western Europe with Ireland, Germany, and the U.K., the source moves east to Italy, Russia, and Hungary before shifting to the Americas and finally to Asia.

Here are the largest immigration sources charted over time, showing the progression.
