Districts of Thailand in the context of "Chiang Rai province"

The provinces of Thailand are administrative divisions of the government of Thailand. The country is divided into 76 provinces (Thai: จังหวัด, RTGS: changwat, pronounced [tɕāŋ.wàt]) proper, with one additional special administrative area (the capital, Bangkok). They are the primary local government units and act as juristic persons. They are divided into amphoe (districts) which are further divided into tambon (sub districts), the next lower level of local government.

All provinces form part of the partially devolved central government, or the regional government (ราชการส่วนภูมิภาค ratchakan suan phumiphak). Majority of public services, including police, prison, transport, public relation and others are still overseen and managed by the province on behalf of the central government. In 1938–1996, the Royal Thai Government proposed that each province should have a council, elected from people resided within that province. The council acts as an advisory and auditing body to the governor (ผู้ว่าราชการจังหวัด phu wa ratchakan changwat), who is appointed by the central government. In 1997, each province has its own provincial administrative organization (องค์การบริหารส่วนจังหวัด ongkan borihan suan changwat), presided over by the president. The PAO manages some public services related to the province. It was expected that the PAO president will become the elected governor (instead of a centrally-appointed one), but the full devolution of the government has not happened. The PAO as well as other municipalities form part of the local self-governing government (ราชการส่วนท้องถิ่น ratchakan suan thongthin).

Tambon (Thai: ตำบล, pronounced [tām.bōn]) is a local governmental unit in Thailand. Below district (amphoe) and province (changwat), they form the third administrative subdivision level. As of 2016 there were 7,255 tambon, not including the 180 khwaeng of Bangkok, which are set at the same administrative level, thus every district contains eight to ten tambon. Tambon is usually translated as "township" or "subdistrict" in English – the latter is the recommended translation, though also often used for king amphoe, the designation for a subdistrict acting as a branch (Thai: king) of the parent district. Tambon are further subdivided into 74,944 villages (muban) as of 2008. Tambon within cities or towns are not subdivided into villages, but may have less formal communities called chumchon (ชุมชน) that may be formed into community associations. The average area of a subdistrict in Thailand is about 70.72 km (27.31 sq mi), while its average population of a subdistrict in Thailand is about 9,637 people.

Phra Pradaeng (Thai: พระประแดง, pronounced [pʰráʔ prā.dɛ̄ːŋ]) is a district (amphoe) of Samut Prakan province in Thailand.
