This may well be a moot subject if (when?) Antarctica becomes all underwater. I think permanent population is irrelevant when deciding to add territory to a map or not, as long as the territories do have the authority to issue coins. There is land there and permanent bases. Countries have claims (which appropriately are “frozen” by treaty, which also does not allow new claims). If it were not for the treaty, there would probably be recognized territories. Using the logic of permanent residents to keep an area on the map, one would have to consider deleting the British Indian Ocean Territory from the map, as the permanent residents were all deported, the majority of the population is American military or foreign contractors and the coinage is non-circulating and even has identical themes to that of the British Antarctic Territory. As for the French Southern and Antarctic Lands, the coinage is non-circulating but there are internationally recognized French claims to part of the territory (not all of it is covered by the Antarctic Treaty, “Adelie Land” is the Antarctic portion) although it has no permanent population other than scientists. If a country or territory is included in the Numista catalogue, I think it is appropriate to be on the map.
