How Asia Is Divided: Regional Classifications Explained

Asia's vast size and diversity allow multiple valid regional divisions. The two most common scholarly frameworks are the six-region model (UN/geographic) and the four-region model (simplified cultural-geographic).

Six-Region Model (UN Statistics Division / Standard Geographic)

1. Central Asia (5): Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan. Post-Soviet, Turkic/Persian, steppe/mountain.
2. East Asia (5+): China, Japan, North Korea, South Korea, Mongolia, Taiwan. Sinosphere influence, high development.
3. North Asia (1+): Russia (Asian part: Siberia, Far East, Urals). Vast, resource-rich, sparse.
4. South Asia (8): Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, Sri Lanka. Indian subcontinent, Indo-Aryan/Dravidian, monsoon.
5. Southeast Asia (11): Brunei, Cambodia, East Timor, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Vietnam. Tropical, maritime/mainland, ASEAN.
6. Western Asia (18+): Armenia, Azerbaijan, Bahrain, Cyprus, Georgia, Iran, Iraq, Israel, Jordan, Kuwait, Lebanon, Oman, Palestine, Qatar, Saudi Arabia, Syria, Turkey, UAE, Yemen. "Middle East" + Caucasus.

Four-Region Model (Simplified Cultural-Geographic)

1. North Asia: Russia (Asia) + Mongolia.
2. East Asia: China, Japan, Koreas, Taiwan.
3. South Asia: Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, Sri Lanka.
4. Southeast Asia: Brunei, Cambodia, East Timor, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Vietnam.

Note: Western Asia is often treated separately as "Middle East/Near East." Central Asia sometimes grouped with "Inner Asia." Divisions reflect trade-offs between physical geography, cultural spheres, political boundaries, and analytical purpose.
