The Gambia (/ˈɡæmbiə/ (listen)), officially the Republic of The Gambia, is a country in West Africa that is almost entirely surrounded by Senegal with the exception of its western coastline along the Atlantic Ocean. It is the smallest country within mainland Africa.
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).
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%.
