Thailand does not have states — it is divided into 76 provinces (called changwat) plus Bangkok, the capital, which functions as a special administrative area, for a total of 77 first-level divisions. Because Thailand is a unitary kingdom rather than a federation, the word "state" does not apply the way it does in the United States or Germany. The provinces are the closest equivalent, but they answer to the central government in Bangkok rather than governing themselves.
Why Thailand Has Provinces, Not States
In a federal country, states hold their own constitutional powers. Thailand, by contrast, is a unitary state, so all real authority flows from the national government. Each of the 76 provinces is led by a governor who is a career civil servant appointed by the Ministry of Interior, not an elected official. This is the single biggest difference between a Thai province and an American state: provincial governors carry out national policy rather than setting their own laws or budgets independently.
Bangkok is the exception that proves the rule. Officially the Bangkok Metropolitan Administration, the capital is not counted as a province at all. It is the only part of Thailand with a directly elected governor, and instead of the standard rural districts it is split into 50 urban districts known as khet. With more than 10 million registered residents — and many more who live there unofficially — Bangkok dwarfs every province in population and economic weight.
The 6 Regions of Thailand
The 76 provinces are grouped into six broad regions, each with its own geography, dialects, and identity:
- Northern Thailand (17 provinces): Mountainous and cool, home to Chiang Mai and Chiang Rai, the historic Lanna culture, and hill-tribe communities.
- Northeastern Thailand / Isan (20 provinces): The largest region by area and population, holding roughly a third of all Thais and a culture closely tied to neighbouring Laos.
- Central Thailand (22 provinces): The fertile rice-growing heartland and floodplain that surrounds Bangkok.
- Eastern Thailand (7 provinces): Industrial and coastal, including Chonburi, home to the beach resort of Pattaya.
- Western Thailand (5 provinces): The smallest region, with rugged terrain along the Myanmar border, including Kanchanaburi.
- Southern Thailand (14 provinces): The long tropical peninsula stretching toward Malaysia, famous for islands like Phuket and Ko Samui.
Largest and Smallest Provinces
The provinces vary enormously in size. Nakhon Ratchasima, also known as Korat, is the giant of the group: it is the largest province by area at about 20,494 km² and also the most populous, serving as the gateway to the Isan region. At the opposite end of the scale sits Phuket, the smallest province at roughly 576 km² — an island better known for its beaches and tourism than its land area.
Other provinces stand out for their remoteness. Mae Hong Son, tucked into the far northwestern mountains, is one of the least accessible and most heavily forested provinces in the kingdom, while the southern border provinces carry a strong Malay-Muslim cultural character distinct from the rest of the country.
How the Administrative System Is Built
Below the provincial level, Thailand uses a tidy hierarchy. Each province is divided into districts (amphoe), which break down into sub-districts (tambon), and finally into villages (muban). This four-tier structure — province, district, sub-district, village — lets the central government administer everything from rural rice-farming hamlets to dense city neighbourhoods using a consistent framework. Bangkok again sits outside this system, using its 50 khet in place of the standard districts.
The number 76 has not always been fixed. Provinces have occasionally been split or created over the decades; Bueng Kan, carved out of Nong Khai in 2011, was the most recent addition, raising the provincial count to its current total.
