The seven-continent model is usually taught in China and most English-speaking countries. The six-continent combined-Eurasia model is preferred by the geographic community, Russia, the former states of the USSR, and Japan. The six-continent combined-America model is taught in Latin America, and some parts of Europe including Greece, Portugal, Spain and Italy. This model may be taught to include only the five inhabited continents (excluding Antarctica)[20][21] — as depicted in the Olympic logo.[22]
