The Maldives is a tropical nation composed of 26 coral atolls made up of hundreds of islands in the Indian Ocean. It relies heavily on tourism as its main industry due to a lack of arable land for agriculture. Some of the top tourist attractions in the Maldives include the National Museum, Mulee-Aage Palace, the Friday Mosque, and the island of Gan, which was formerly inhabited but is now a tourist resort. Tourism has boosted the Maldivian economy but the country remains relatively poor with an average annual income of around £1,390 per person. It must import most of its food and runs an annual trade deficit exceeding £12.5 million.
