Do people live in Antarctica?
The general answer is no, as there are no permanent residents of Antarctica. Several contries however, do maintain permanent research stations with scientists and support personnel that number up to 5,000 in the summer and about 1,000 in the winter. Most researchers do not stay through the winter but those that do are typically there on one-year assignments.
The United States has two primary bases there: Amundsen-Scott South Pole Station and McMurdo Station.
An interesting aside: the South Pole has no solar time so a station there could theoretically be in any of the world’s 24 time zones. They use New Zealand time (UTC +12) since all flights to the continent come from Christchurch.
