The Gambia, officially the Republic of The Gambia, is a country in Western Africa. The Gambia is often referred to as 'The Smiling Coast'. It is the smallest country within mainland Africa, and is surrounded by Senegal, except for its western coast on the Atlantic Ocean. The Gambia is situated on both sides of the lower reaches of the Gambia River, the nation's namesake, which flows through the centre of The Gambia and empties into the Atlantic Ocean. It has an area of 10,689 square kilometres (4,127 sq mi) with a population of 1,857,181 as of the April 2013 census. Banjul is the Gambian capital and the largest cities are Serekunda and Brikama. In 1965, The Gambia gained independence. The Gambia's economy is dominated by farming, fishing and, especially, tourism. In 2015, 48.6% of the population lived in poverty. In rural areas, poverty is even more widespread, at almost 70%.
