Singapore officially the Republic of Singapore, and often referred to as the Lion City, the Garden City, and the Red Dot, is a leading global city-state and island country in Southeast Asia. It lies one degree (137 km; 85 mi) north of the equator, at the southernmost tip of continental Asia and peninsular Malaysia, with Indonesia's Riau Islands to the south. Singapore's territory consists of the diamond-shaped main island (commonly referred to as Singapore Island and Pulau Ujong in Malay) and more than 60 significantly smaller islets. Since the 1960s, ongoing land reclamation has increased Singapore's land area, which is highly urbanised, by at least 20%.
