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. The same trend is clear looking at the history of New York City’s foreign born population.

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

While it may seem that immigration over the last few decades has been higher than ever before, the picture looks very different when viewed relative to the size of the U.S. population.

Here is the same chart, with the immigration shown as a percentage of the U.S. population.
