In 1960, Greater Accra Region, then referred to as Accra Capital District, was geographically and legally part of the Eastern Region. It was, however, administered separately by the Minister responsible for local government. On 23 July 1982, Greater Accra was created by the Greater Accra Region Law (PNDCL 26) as a legally separate region to include the Ada local council area.
The region is administered at two different but complementary levels, the traditional and political levels. The traditional level of administration is through an intricate network of local governance dealing with purely traditional affairs concerning customs and land administration, while there is along the lines of law and order and decentralized government machinery.
The operation of the region is through the local government system that derives its authority from the 1992 Constitution of Ghana and the Local Government Act 1993 (Act 462). Under this administration, the region is divided into five areas/districts with their capitals.
The population of the region according to the 2010 Population and Housing Census stands at 4,010,054 with 1,938,225 males and 2,071,829 females.
