The borough was formed in 1965 by the London Government Act 1963 as the London Borough of Barking. The constituent areas were virtually all of the Municipal Borough of Barking as well as the largest part of the Municipal Borough of Dagenham, the former area of which was transferred to Greater London from Essex. It is an Outer London borough and the south is inside the London Riverside part of the Thames Gateway, which is an region designated as a national priority for urban regeneration. It covers a total area of 13.93 square miles.
Based on the 2011 census, the area has a population of about 198294, the majority of which reside within the Becontree estate. Major settlement of the region, mostly escaping slum conditions within the East End of London, occurred through the period when the new motor and chemical industries, including the Ford Motor Company plant at Dagenham were established. Since the decline of those industries during the 1980s, employment has shifted more towards service sector jobs.
Much of the borough is inside the London Riverside area of the Thames Gateway zone and it is the site of considerable property developing along with other development. The local authority is Barking and Dagenham London Borough Council.
