Thanks to Mental Floss for this great graphic of immigration changes from 1910-2010 (click on the image for a more readable illustration). One thing I learned is that Canadians really seem to like cold weather. I thought maybe they would migrate predominantly to the US South or perhaps Hawaii, but why would they choose those beautiful, sunny places when they could go to Montana and North Dakota instead?
It’s also amazing to see how varied immigration was in 1910 (what was up with Nevada and the Italians?) and how dominant Mexican immigration is 100 years later.
