Singapore, an island city-state off southern Malaysia, is a global financial center with a tropical climate and multicultural population. Its colonial core centers on the Padang, a cricket field since the 1830s and now flanked by grand buildings such as City Hall, with its 18 Corinthian columns. In Singapore's circa-1820 Chinatown stands the red-and-gold Buddha Tooth Relic Temple, said to house one of Buddha's teeth. Singapore is a global commerce, finance and transport hub. Its standings include: the most "technology-ready" nation (WEF), top International-meetings city (UIA), city with "best investment potential" (BERI), second-most competitive country, third-largest foreign exchange market, third-largest financial center, third-largest oil refining and trading center, and the second-busiest container port. The country has also been identified as a tax haven. Singapore ranks 5th on the UN Human Development Index and the 3rd highest GDP per capita. It is ranked highly in education, healthcare, life expectancy, quality of life, personal safety, and housing. Although income inequality is high, 90% of homes are owner-occupied. 38% of Singapore's 5.6 million residents are permanent residents and other foreign nationals. There are four official languages: English (common and first language), Malay, Mandarin, Tamil; almost all Singaporeans are bilingual.
