Thailand, the only Southeast Asian nation never to have been colonized by European powers, is a constitutional monarchy whose current head of state is HM Bhumibol Adulyadej. A unified Thai kingdom has existed since the mid-14th century, and Thailand was known as Siam until 1939 when it officially became the Kingdom of Thailand.


Thailand is the 50th largest country in the world; most nearly equal in size to Spain. Located just 15 degrees north of the equator, Thailand has a tropical climate and temperatures typically range from 19 to 38 degrees C (66-100 F). Thailand’s largest peak, Doi Inthanon, is 2,565 meters (8,415 ft) tall. Thailand covers 510,890 sq km of land and 2,230 sq km of water. The coastline of Thailand is 3,219 km long. Thailand’s longest shared border is with Myanmar (Burma), stretching 1,800 km.


Thailand enjoys a tropical climate with 3 distinct seasons --- summer from March to May with average temperatures of 34 degrees Celsius and 75% humidity, monsoon with plenty of sunshine from June to September with an average daily temperature of 29 degrees Celsius and 87% humidity, and cool from October to February. Temperatures then range from 32 degrees Celsius to below 20 degrees Celsius with a drop in humidity. At night, much lower temperatures are experienced in the North and Northeast. The South has a tropical rainforest climate with temperatures averaging 28 degrees Celsius almost all year round.


The population of Thailand comprises of roughly 67 millions citizens, the majority of whom are ethnically Thai, though peoples of Chinese, Indian, Malay, Mon, Khmer, Burmese, and Lao origin are also represented to varying degrees. Approximately 7 million citizens live in the capital city, Bangkok, though this number varies seasonally and is otherwise difficult to accurately count.


The vast majority (roughly 80%) of Thailand’s nearly 65 million citizens are ethnically Thai. The remainder consists primarily of peoples of Chinese, Indian, Malay, Mon, Khmer, Burmese, and Lao decent. Of the 7 million citizens who live in the capital city, Bangkok, there is a greater diversity of ethnicities, including a large number of expatriate residents from across the globe. Other geographic distinctions of the population include a Muslim majority in the south near the Malaysian border, and hill tribe ethnic groups, such as the Hmong and Karen, who live in the northern mountains.


More than 92% of the population speaks Thai or one of it’s regional dialects. While the Thai language is the official language of Thailand, as a result of its cosmopolitan capital city and established tourism infrastructure, English is spoken and understood throughout much of Thailand.


94.6% of Thais are Buddhist, 4.6% of Thais are Muslim 0.7% of Thais are Christian

Electrical outlets in Thailand are charged to 220v at 50 cycles per second, which is compatible with appliances from the U.K. but not those from the US and many other nations. While most computer cables have adaptors for voltage, visitors from the U.S. and those not on the 220/50 v. will have to bring adapters to run most other appliances. Outlets in Thailand generally feature flat, two pronged plugs, though some feature holes for round plug ends. Few outlets feature three holes (grounded outlets) so it is often necessary to have a three to two prong adapter for using notebook computers in Thailand.
