South Londonders complain that people from North London tend to look down on them and their region, and ignore South London's history and its status as the site of such things as Lambeth Palace. The London Underground network is largely concentrated in North London - there are only 30 stations south of the river compared to many times that north of it, despite roughly equal populations. Historically this has been due to the difficulty in tunnelling through the geology of South London. With the Jubilee Line extension in the late 1990s and the proposed East London Line Extension this disparity is being rectified.
South London consists of the boroughs of Bexley, London Borough of Bromley, Croydon, Greenwich, Kingston, Lambeth, Lewisham, Merton, Southwark, Sutton, London Borough of Wandsworth. The London Borough of Richmond straddles the river.
