Zero permanent residents. Antarctica is governed by the **Antarctic Treaty System (1959)**—no sovereignty, no commercial exploitation, no indigenous population.
| Season | Months | Population | Activity |
|---|---|---|---|
| Summer | Oct–Feb | ~4,000–5,000 | Field science, construction, logistics, tourism support. 24-hr daylight. |
| Winter | Mar–Sep | ~1,000 | Core maintenance, long-term observations (atmospheric, seismic, astronomical). Total darkness (pole). |
~100,000/year (ship-based, Peninsula only). **No overnight stays on land** (except rare guided camps).
