Asia is the world’s largest and most populous continent. It covers roughly 30% of Earth’s land area and is home to approximately 60% of the global population. Stretching from the Mediterranean and the Ural Mountains in the west to the Pacific Ocean in the east, and from the Arctic in the north to the Indian Ocean in the south, Asia contains extraordinary geographic, cultural, linguistic, and economic diversity.

Geography

Asia is traditionally divided into several major regions:

• East Asia – China, Japan, South Korea, North Korea, Mongolia, Taiwan
• Southeast Asia – Indonesia, Vietnam, Thailand, Philippines, Malaysia, Singapore, Myanmar, Cambodia, Laos, Brunei, Timor-Leste
• South Asia – India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan, Maldives, Afghanistan
• Central Asia – Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan, Tajikistan
• West Asia (Middle East) – Turkey, Iran, Saudi Arabia, Iraq, Syria, Israel, Jordan, Lebanon, Yemen, Oman, UAE, Qatar, Bahrain, Kuwait, Cyprus, and others
• North Asia – the Asian portion of Russia (Siberia)

The continent includes the highest mountains on Earth (the Himalayas), vast deserts (Gobi, Arabian), dense tropical rainforests, extensive river systems (Yangtze, Ganges, Mekong, Indus, Yellow River), and some of the world’s most active tectonic zones.

Population & Diversity

Asia is home to more than 4.7 billion people. Major population centers include the Indo-Gangetic Plain, the North China Plain, the island of Java, and the mega-cities of Tokyo, Shanghai, Delhi, Mumbai, Beijing, Seoul, Jakarta, and Manila.

The continent contains hundreds of languages and language families (Sino-Tibetan, Indo-European, Austronesian, Dravidian, Turkic, Afro-Asiatic, and many others). It is the birthplace of major world religions and philosophical traditions, including Hinduism, Buddhism, Confucianism, Taoism, Islam, Christianity, Judaism, Sikhism, and Jainism.

Economy

Asia contains both highly developed economies and rapidly growing emerging markets. Key economic features include:

• Advanced manufacturing and technology hubs in East Asia (Japan, South Korea, Taiwan, China)
• Large service and software sectors in India
• Significant energy resources in West and Central Asia
• Growing middle classes and urbanization across much of South and Southeast Asia
• Major global trade routes, including the Strait of Malacca and key Pacific and Indian Ocean shipping lanes

In investment contexts, the term “Asia ex-Japan” (often abbreviated AxJ) is frequently used to refer to Asian markets excluding Japan, reflecting the distinct economic profile of Japan as a mature developed economy compared with many other Asian markets.

Contemporary Notes

Asia continues to play a central role in global affairs. Issues of economic development, demographic change, climate vulnerability (especially in low-lying coastal and island areas), resource management, technological innovation, and regional security remain subjects of ongoing attention. Independent reporting and open information flows are essential for understanding the continent’s many distinct societies and trajectories.
