This table from Gallup is based on a sample of people around the world who say they would like to move to another country permanently. The percentages indicate how many would choose the United States (and Canada as well).
America is most popular among people from Asia, and least popular among those from the Middle East and North Africa. Isn't it great when feelings are mutual?
I'm pleased to see that so many people are not choosing the United States. We need to do what we can to convince the world that this place is a hellhole so they'll move someplace else.
