East London could be many things. It could be the eastern half of Greater London; it could be the former sub region, as determined by the London Plan; or it could be a part of the capital city that generally lies east of the city centre. The London Plan is a planning document that was first written by the city's mayor in 2004. When it was first completed, the document contained five sub regions: North, South, East, West and Central. In 2008, however, the document was revisited and the sub regions were changed. The whole idea of the plan is to act as a strategy for spatial development and one of the objectives is to make the city a better place to live. So in 2008, the sub regions were changed to reflect these objectives and now include five sub regions, listed as West, North, North East, South West and South East.
But that doesn't mean that East London no longer exists. It formerly included a population of nearly 2 million people, who now live in either North East London or South East London, according to the new plan. The former designation included the boroughs of Bexley, Barking and Dagenham, Greenwich, the City of London, Lewisham, Havering, Newham, Hackney, Tower Hamlets and Redbridge. Today, the combined sub regions of South East and North East London comprise the boroughs of Barking & Dagenham, Havering, the City of London, Newham, Redbridge, Tower Hamlets, Waltham Forest, Bexley, Bromley, Lewisham, Greenwich and Southwark. These two sub regions today are home to 2.7 million people and 1.4 million jobs.
