What percent of the population do you estimate are expats? From where?
Less than one %, surely. There is an American community in Nha Trang that I know of and, of course in Hà Nội and Đà There are a lot of Australian tourists that say they will stay, but only a tiny few do. Nẵng There were a lot of Russians in Nha Trang a few years ago but I don’t see them any more. There are some French but they stay low key and a some Koreans. I avoid the foreigners.
