I'm talking per capita. I've now edited the above comment and added a source.

Sorry for the confusion, I don't know why I thought that since I was talking about percentages it would be obvious I'm referring to per capita numbers, because re-reading my comment I see it's ambiguous.

But come on, have a heart. New Zealand only has 5 million people in it, total. You must think I'm incredibly, mindblowingly stupid if you think I'm saying the US somehow has fewer immigrants than that!
