What Do You Call Someone from Antarctica? The Answer Isn't What You'd Expect

There is no demonym for permanent residents of Antarctica—because there are none.

The continent has no indigenous or permanent population. Only temporary residents:

• Scientists and researchers (summer: ~5,000; winter: ~1,000)
• Support staff (logistics, maintenance, medical, culinary)

They are referred to by their role or nationality:

• Antarctic researchers / scientists
• Expedition members
• Support personnel
• [Nationality] Antarctic program participants (e.g., "USAP participants")

The Antarctic Treaty (1959) reserves the continent for peaceful science. No one is "from" Antarctica in the national sense.
