The central island is heavily urbanised, with the built-up area taking up essentially its entire landmass.  Slightly less than one third of the nation's population lives in the capital city, and the population has increased from 20,000 people in 1987 to 100,000 people in 2006. Many Maldivians and foreign workers living in other parts of the country find themselves in occasional short term residence on the island since it is the centre of administration and bureaucracy.
