Over 4.2 billion people live in Asia, according to United Nations ESCAP. This accounts for 60 percent of Earth's population.
Asia, the world's largest and most populous continent, is located in the eastern and northern hemispheres. Bounded by the Arctic Ocean to the north, the Pacific Ocean on the east and the Indian Ocean on the south, Asia has 51 countries, with India and China being the most populous nations. Maldives is Asia's least populous nation. The population growth rate in Asia is very high, and it quadrupled over the last 100 years.
Although there has been great progress in reducing hunger and providing access to healthcare, education and basic services on the continent, an estimated 641 million Asians survive on less than $1 every day.
