Accra is the capital and largest city of Ghana, located on the southern coast at the Gulf of Guinea, which is part of the Atlantic Ocean. Accra covers an area of 225.67 km2 (87.13 sq mi) with an estimated urban population of 4.2 million as of 2020. It is organized into 12 local government districts – 11 municipal districts and the Accra Metropolitan District, which is the only district within the capital to be granted city status. "Accra" usually refers to the Accra Metropolitan Area, which serves as the capital of Ghana, while the district under the jurisdiction of the Accra Metropolitan Assembly is distinguished from the rest of the capital as the "City of Accra". In common usage, however, the terms "Accra" and "City of Accra" are used interchangeably.
