Singapore, officially the Republic of Singapore, is an island city-state located at the southern tip of the Malay Peninsula, lying 137 kilometres (85 mi) north of the equator, south of the Malaysian state of Johor and north of Indonesia's Riau Islands. At 710.2 km2 (274.2 sq mi), Singapore is a microstate and the smallest nation in Southeast Asia. This is orders of magnitude larger than Monaco and Vatican City, the only other surviving sovereign city-...states.

Before European settlement, the island now known as Singapore was the site of a Malay fishing village at the mouth of the Singapore River. Several hundred indigenous Orang Laut people also lived along the nearby coast, rivers and on smaller islands. In 1819, the British East India Company, led by Sir Stamford Raffles, established a trading post on the island, which was used as a port along the spice route. Singapore became one of the most important commercial and military centres of the British Empire, and the hub of British power in Southeast Asia.

Since independence, Singapore's standard of living has risen dramatically. Foreign direct investment and a state-led drive to industrialization based on plans drawn up by the Dutch economist Albert Winsemius have created a modern economy focused on industry, education and urban planning. Singapore is the 5th wealthiest country in the world in terms of GDP (PPP) per capita. In December 2008, the foreign exchange reserves of this small island nation stood at around US$174.2billion.  In 2009, the Economist Intelligence Unit ranked Singapore the tenth most expensive city in the world in which to live—the third in Asia, after Tokyo and Osaka.The 2009 Cost of Living survey, by consultancy firm Mercer, has ranked Singapore similarly as the tenth most expensive city for expatriates to live in.

The population of Singapore including non-residents is approximately 4.86 million. Singapore is highly cosmopolitan and diverse with Chinese people forming an ethnic majority with large populations of Malay, Indian and other people. English, Malay, Tamil, and Chinese are the official languages.

Singapore is a parliamentary republic, and the Constitution of Singapore establishes representative democracy as the nation's political system. The People's Action Party (PAP) dominates the political process and has won control of Parliament in every election since self-government in 1959.
