ASIA

Asia is the world’s largest and most populous continent, covering about 30% of Earth’s total land area. Asia is notable for not only its overall size and population but its dense as well as barely populated regions within the continent of 4.4 [?] billion people. Asia has exhibited economic as well as population growth during the 20th century, but overall population growth has since fallen to world average levels. Given its size and diversity, the concept of Asia may actually have more to do with human than physical geography. Asia varies greatly across its regions with regard to ethnic groups, cultures, environments, economics, historical ties and government systems.
