非居民
核心畫面
Picture a line drawn around a place, with the people who actually live inside it on one side. A non-resident is anyone standing on the other side of that line — they may own a flat inside it, eat there, or come back every year, but they are counted as living somewhere else. The line is about living, not about belonging, and that is why it can be drawn around a country or around a single hotel.

可以想成在一個地方外面畫一條線，真正住在裡面的人站在一邊。non-resident 就是站在線另一邊的人：他可能在裡面有房子、常常來吃飯、每年回來一趟，但在紀錄上他算是住在別的地方。這條線量的是「住不住在這裡」，不是「是不是自己人」。也因為量的是居住，同一條線可以畫在一個國家外面，也可以畫在一家旅館外面。From the word’s history
Wiktionary records the word as non- + resident, and resident comes from reside, to live somewhere. So the word has always been about where a person lives, not about where they come from.
來源資料記錄這個字是 non- 加上 resident，而 resident 又來自 reside（居住）。所以這個字從組成上看，講的一直是「住在哪裡」這件事，跟出身或國籍沒有關係。這正好解釋了為什麼一個本國公民長住國外之後，也會被算成 non-resident。
