How much of the earth land mass is unpopulated?

Approximately 68% of the Earth's landmass is considered unpopulated or sparsely populated. This includes vast areas such as deserts, mountains, forests, and tundra, where human settlement is minimal or nonexistent. Regions like the Sahara Desert, the Arctic, and remote mountainous areas contribute significantly to this unpopulated land. However, the exact percentage can vary based on definitions of population density and what constitutes "unpopulated."
