Thailand, officially the Kingdom of Thailand, formerly known as Siam, is a country at the centre of the Indochina peninsula in Southeast Asia. It is bordered to the north by Burma and Laos, to the east by Laos and Cambodia, to the south by the Gulf of Thailand and Malaysia, and to the west by the Andaman Sea and the southern extremity of Burma. Its maritime boundaries include Vietnam in the Gulf of Thailand to the southeast, and Indonesia and India on the Andaman Sea to the southwest. Thailand is a monarchy headed by King Bhumibol Adulyadej, Rama IX and governed by a military junta that took power in May 2014. The king is the ninth of the House of Chakri, and has reigned since 1946 as the world's longest-serving current head of state and the country's longest-reigning monarch. The King of Thailand's titles include Head of State, Head of the Armed Forces, Adherent of Buddhism, and Upholder of religions. Although a constitutional system was established in 1932, the monarchy and military have continued to intervene periodically in politics. With a total area of approximately 513,000 km2 (198,000 sq mi), Thailand is the world's 51st-largest country. It is the 20th-most-populous country in the world, with around 66 million people. The capital and largest city is Bangkok, which is Thailand's political, commercial, industrial, and cultural hub. About 75–95% of the population is ethnically Tai, which includes four major regional groups: central Thai, northeastern Thai (Khon [Lao] Isan), northern Thai (Khon Mueang); and southern Thai. Thai Chinese, those of significant Chinese heritage, are 14% of the population, while Thais with partial Chinese ancestry comprise up to 40% of the population. Thai Malays represent 3% of the population, with the remainder consisting of Mons, Khmers and various "hill tribes". The country's official language is Thai and the primary religion is Buddhism, which is practised by around 95% of the population. Thailand experienced rapid economic growth between 1985 and 1996, becoming a newly industrialised country and a major exporter. Manufacturing, agriculture, and tourism are leading sectors of the economy. Among the ten ASEAN countries, Thailand ranks second in quality of life and the country's HDI had been rated as "high". Its large population and growing economic influence have made it a middle power in the region and around the world.

1.  Relying on agencies from each country, as well as a synthesis of data from United Nations divisions, Eurostate Demographic statistics, the U.S. Census international database, and its own data collection, the World Bank’s Open Data site offers free and open access to data about development in countries around the globe.

2.  The U.S. State Department's International Religious Freedom Report is submitted to Congress annually by the Department of State in compliance with Section 102(b) of the International Religious Freedom Act (IRFA) of 1998.

3.  The article by Brian Grim and Roger Finke describes the coding of the U.S. State Department’s International Religious Freedom reports. The 2003, 2005, and 2008 reports were coded by researchers at the Association of Religion Data Archives. The GRI, GFI and SRI values reported on the National Profiles are averages from the 2003, 2005, and 2008 International Religious Freedom reports, while the Religious Persecution measure is an average from the 2005 and 2008 reports. All other measures derived from the International Religious Freedom reports were coded from the reports 2008. A data file with all of the 2008 coding, as well as data files with other cross national collections are available for preview and download from the data archive on this site. Used with permission.
