The continent known for being the least populated is Antarctica. Unlike other continents that have large human populations, Antarctica is primarily inhabited by scientists and researchers who live temporarily at various research stations. The extreme climate, characterized by frigid temperatures and harsh weather conditions, makes permanent habitation impractical. As a result, the continent's population varies seasonally, with around 1,000 residents in the winter and up to 5,000 in the summer months. Most of Antarctica's land is covered in ice, contributing to its unique status as a largely uninhabited region, focused on scientific research rather than human settlement.
