The "comuna de la Antártica", which encompasses most of the the area of the province, is disputed, as it forms the Chilean sector of Antarctica, stretching to the South Pole, which is generally unrecognised as part of Chile, being subject to the Antarctic Treaty. It is practically uninhabited except for research stations of various countries, although Chile attempts to give the appearance of permanent habitation at the "capital" Puerto Covadonga, by the presence of women and children, and a small school, in order to support its territorial claim of the area. The official population figure for the area as of the census 2002 is given as 130 (115 male, 15 female). This does not include the staff of non-Chilean bases in the area.
