North London is the northern part of London, England. It is an imprecise description and the area it covers is defined differently for a range of purposes. Common to these definitions is that it includes districts located north of the River Thames and is used in comparison with South London.
For the purposes of the London Plan, there has been a North London sub-region in operation since 2004, originally consisting of Barnet, Enfield, Haringey and Waltham Forest. In 2001 this area had a population of 1,042,000. This definition is used by organisations such as Connexions. In 2008 it was amended and it now consists of Barnet, Camden, Enfield, Hackney, Haringey, Islington and Westminster.
