I think you can answer that from your very first sight of the terrain! It is the coldest, driest, most unproductive continent lying at the bottom of the world. The continent of Antarctica is covered by thick layers of ice and is only reachable in the summer months. There is no winter transport. This would be the first reason.
The second is that the only people there are research scientists and their support staff, most of whom are summer only residents. The temperature is so severe that a means of keeping the accommodation warm enough and stocked with supplies is reliant on supplies brought in the summer.
Survival outside is limited to intrepid explorers with months of preparation and specialist equipment and clothing. Without a reasonable means of having shops, houses, entertainment places and transport and with consistently miserable climate, who would want to live there.
