This is a list of continental landmasses, continents, and continental subregions by population. For statistical convenience, the populations of continental landmasses also include the populations of their associated islands .
According to modern definitions, a supercontinent does not exist today; [1] the closest is the current Afro-Eurasian landmass, which covers approximately 57% of Earth's total land area. The last period in which the continental landmasses were near to one another was 336 to 175 million years ago, forming the supercontinent Pangaea .
