When I was in McMurdo station in Antarctica on the way to the South Pole I happened to be there at the same time as the Navy cargo unloading crew. McMurdo banned all alcohol sales while the Navy was in town.

For another sense of scale, Svalbard has 61,022 km^2 and Antarctica 14,200,000 km^2.

So even when Antarctica might have more people at times, its population density is still way lower.
