Lewisham is one of the largest of the inner London boroughs, with an area of 13.7 square miles. It lies south-east of the City, between Southwark to the west, Greenwich to the east, and Bromley to the south. There is a short frontage to the Thames in the north. The 2001 census estimated the population at just under 250,000, of whom nearly a quarter described themselves as black or black British.
