We know about the situation called - exodus. But is there any single word to name the people who are in that exodus? I mean, is there any single word to describe people who are leaving a place in mass for better situation or for any otehr reason?
According to M-W, an exodus is "a mass departure: EMIGRATION", where EMIGRATION means "an act or instance of emigrating : departure from a place of abode, natural home, or country for life or residence elsewhere." This suggests émigré as an appropriate answer. It has the advantage of being more general than words like refugee (one could emigrate for any number of reasons), but like refugee and other words, it need not always connote the idea of a mass departure, although it often does.
