Which continent comprises 12 percent of the world's land area but only 6 percent of the global population?

The statement reflects demographics and geography related to South America. South America accounts for approximately 12 percent of the Earth's total land area, which is significant, considering its size and the variety of ecosystems present, from the Amazon rainforest to the Andes mountains. In terms of population, however, South America holds only around 6 percent of the global population, showing a disparity between land area and population density.

This region's relatively low population density can be attributed to factors such as vast uninhabitable areas, like deserts and rainforests, as well as urbanization trends where large populations are concentrated in cities while significant portions of the continent remain sparsely populated. Thus, the answer accurately reflects the balance of land and human inhabitants on the continent compared to others like Africa, North America, or Asia, which have higher population densities relative to their land areas.
