Asia is the largest continent in the world in terms of both land area and population. It covers around 17 million square miles and is home to over four billion individuals. Asia is divided into 48 countries, three of them are trans-continental. Given its large size, Asia has been subdivided on the basis of many factors including cultural, political, etc. Physiographically, there are five major regions of Asia. These are Central Asia, East Asia, South Asia, Southeast Asia, and Western Asia. Another region can be defined as North Asia to include the bulk of Siberia of Russia and the northeastern parts of Asia. The five main divisions of Asia have been mentioned in detail below.
5. Central Asia (Tajikistan, Uzbekistan, Kazakhstan, Turkmenistan, Kyrgyzstan)
Central Asia is west of China, south of Russia, and north of Afghanistan. The western border of this region runs along the Caspian Sea. Central Asia is politically divided into five countries: Tajikistan, Uzbekistan, Kazakhstan, Turkmenistan, and Kyrgyzstan. Given that the name of each of these countries ends in "-stan," Central Asia is sometimes informally referred to as "The Stans." The region covers a total area of 1,545,741 square miles and has a population size of just over 69.78 million individuals. Central Asia played an important role in the transportation of goods between China and Europe during the Silk Road trading era.
4. East Asia (China, Mongolia, North Korea, South Korea, Japan, Hong Kong, Taiwan, Macau)
East Asia, one of the five regions of Asia, is located east of Central Asia, with its eastern border running along the East China Sea. East Asia is politically divided into eight countries and regions: China, Mongolia, North Korea, South Korea, Japan, Hong Kong, Taiwan, and Macau. This region covers a total area of 4,571,092 square miles and has a population size of more than 1.641 billion, which represents 22% of the global population and 38% of Asia's total population. Many residents of East Asia are concentrated in major metropolitan areas such as Beijing and Tokyo.
The geography of East Asia is varied depending on the zone. The inner continental area experiences a temperate climate, while Mongolia is covered by the arid Gobi desert. China, the largest country in the region, is home to both mountains and plateaus, while Japan is characterized by thousands of islands and coastlines. Today, East Asia is believed to have some of the most advanced technologies in the world, which fosters economic development.
3. South Asia (Sri Lanka, Bangladesh, India, Afghanistan, Pakistan, Bhutan, Nepal, the Maldives)
South Asia has a peninsula-like shape that is bordered by three bodies of water: the Indian Ocean to the south, the Bay of Bengal to the east, and the Arabian Sea to the west. The region includes Indian subcontinent and surrounding countries. South Asia is politically divided into eight autonomous countries: Sri Lanka, Bangladesh, India, Afghanistan, Pakistan, Bhutan, Nepal, and the Maldives. The region covers a total area of roughly two million square miles and has a population size of more than 1.74 billion, which is nearly a quarter of the global population. Additionally, South Asia has the distinction of being the most densely populated area in the world.
2. Southeast Asia (Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Timor Lester, Vietnam, Christmas Island, Cocos Islands)
Southeast Asia is located north of Australia, south of East Asia, west of the Pacific Ocean, and east of the Bay of Bengal. It encompasses several island and archipelago nations that stretch between the northern and southern hemispheres, making it the only Asian region located on both sides of the equator. Southeast Asia is politically divided into 15 countries and territories: Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Timor Leste, Vietnam, Christmas Island, Cocos Islands.
Southeast Asia covers a total area of 1,735,121 square miles and has a population size of more than 641 million individuals. The geography of Southeast Asia is characterized by a large number of archipelagos. The Indonesian Archipelago is the biggest in the world and is home to the largest number of active volcanoes in the world. The region's importance in global trade began during the spice trade, which started before European exploration. Today, the economy of Southeast Asia is rapidly developing. Indonesia is considered the largest economy in the region and is East Asia's only member of the G20.
1. Western Asia (Georgia, Armenia, Azerbaijan, Turkey, Cyprus, Syria, Lebanon, Israel, Palestine, Jordan, Iraq, Iran, Kuwait, Bahrain, Qatar, Saudi Arabia)
West Asia is located in the area between Central Asia and Africa, south of Eastern Europe. The majority of the region is often referred to as the Middle East, although it geographically excludes the mainland of Egypt (which is culturally considered a Middle Eastern country). West Asia is politically divided into 19 states: Georgia, Armenia, Azerbaijan, Turkey, Cyprus, Syria, Lebanon, Israel, Palestine, Jordan, Iraq, Iran, Kuwait, Bahrain, Qatar, Saudi Arabia, United Arab Emirates, Oman, and Yemen. It also includes the Sinai Peninsula of Egypt. The region covers a total area of around 2.415 million square miles and has a population size of 313.428 million.
A large area of the region is covered by an arid desert environment. However, West Asia does have several points of access to large bodies of water, including the Black Sea, Persian Gulf, Arabian Sea, Red Sea, Caspian Sea, Mediterranean Sea, and the Aegean Sea.
