Singapore, officially the Republic of Singapore, is an island country and city-state in Southeast Asia. The country's territory comprises one main island, 63 satellite islands and islets, and one outlying islet. It is about one degree of latitude (137 kilometres or 85 miles) north of the equator, off the southern tip of the Malay Peninsula, bordering the Strait of Malacca to the west, the Singapore Strait to the south along with the Riau Islands in Indonesia, the South China Sea to the east, and the Straits of Johor along with the State of Johor in Malaysia to the north.

As a highly developed country, it has the highest PPP-adjusted GDP per capita in the world. It is also identified as a tax haven. Singapore is the only country in Asia with a AAA sovereign credit rating from all major rating agencies. It is a major aviation, financial, and maritime shipping hub and has consistently been ranked as one of the most expensive cities to live in for expatriates and foreign workers. Singapore ranks highly in key social indicators: education, healthcare, quality of life, personal safety, infrastructure, and housing, with a home-ownership rate of 88 per cent. Singaporeans enjoy one of the longest life expectancies, fastest Internet connection speeds, lowest infant mortality rates, and lowest levels of corruption in the world. Singapore is organised into five regions and 55 planning areas. It has the third highest population density of any country, although there are numerous green and recreational spaces as a result of urban planning. With a multicultural population and in recognition of the cultural identities of the major ethnic groups within the nation, Singapore has four official languages: English, Malay, Mandarin, and Tamil. English is the common language, with exclusive use in numerous public services. Multi-racialism is enshrined in the constitution and continues to shape national policies.
