Regions of Thailand

Thailand is variably divided into different sets of regions, the most notable of which are the six-region grouping used in geographic studies, and the four-region grouping consistent with the Monthon administrative regional grouping system formerly used by the Ministry of Interior. These regions are the largest subdivisions of the country.

Six-region division system

Four-region division system

Meteorological division system

In contrast to the administrative divisions of the provinces of Thailand, the regions no longer have an administrative character, but are used for statistical or academic purposes.

Grouping systems

A six-region system is commonly used for geographical and scientific purposes. This system dates to 1935.^[1] It was formalised in 1977 by the National Geographical Committee, which was appointed by the National Research Council. It divides the country into the following regions:

The four-region system, used in some administrative and statistical contexts, and also as a loose cultural grouping, includes the western and eastern regions within the central region, while grouping the provinces of Sukhothai, Phitsanulok, Phichit, Kamphaeng Phet, Phetchabun, Nakhon Sawan, and Uthai Thani in the northern region. This is also the regional system most commonly used on national television, when discussing regional events. It divides the country into the following regions:

The Thai Meteorological Department divides the country into six regions for meteorological purposes.^[2] It differs from the four-region system in that the east is regarded as a separate region, the south is divided into east and west coasts, and Nakhon Sawan and Uthai Thani are grouped in the central region.

Regional economic disparities

Thailand's economic activities are concentrated in Bangkok and the central region. In 2013, the central region's gross regional product (GRP) contributed 40.9 percent to Thailand's GDP. Other regions accounted for 10.9 percent (northeastern); 8.8 percent (northern); and 8.6 percent (southern). GRP per capita varied. The average GRP per capita of the central region was 280,734 baht, while that of the northeastern region was 74,532 baht.^[3]
