Surprised me how much came from Canada -- has that been a thing Looking at the absolute number of immigrants per year skews things a bit in Canada's favour; the low barrier to movement means that there's relatively more Canadians who live in the USA for short durations. I'm sure that Canada is a much smaller proportion of the stock of immigrants than than its proportion of the annual inflow.
