What is considered an island?
Island
An island or isle is any piece of sub-continental land that is surrounded by water.[2] Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. A grouping of geographically or geologically related islands is called an archipelago, such as the Philippines.
Administrative divisions of the Maldives
A city is an inhabited area with a population of 25,000+. The criteria also includes a certain level of economic development and facilities available. A city has a "city council" which governs over the affairs of the city, and keeps communication with the central government. A city will not be included within an administrative atoll. A city has further subdivisions called "wards" or "districts". A city council will also govern over any uninhabited islands or resort islands within its designated area. 
There are two cities in Maldives. They are Male’ and Addu.
