Asia

Asia is the world's largest and most populous continent, located in the eastern and northern hemispheres. It covers about 9% of the Earth's total surface area (or 30% of its land area) and with approximately 3.879 billion people, it has 60% of the world's current human population. During the 20th century Asia's population nearly quadrupled. That's just about whatever the population before was, multiplied by 4. That's allot!
