The Greater London Built-up Area or Greater London Urban Area is the conurbation or continuous urban area based around London, United Kingdom, as defined by the Office for National Statistics.[1] It had a population of 9,787,426 in 2011 at the time of the census.[1]

Overview[edit]

The Greater London Built-up or Urban Area had a population of 9,787,426 and occupied an area of 1,737.9 square kilometres (671.0 sq mi) at the time of the 2011 census.[1]

It includes most of Greater London, omitting most of its woodland, small, buffered districts, the Lea Valley Park and the two largest sewage treatment works serving London by the River Thames. Outside the administrative boundary it includes adjacent areas of densest settlement and a few densely populated outliers connected to it by ribbon development. Its outer boundary is constrained by the Metropolitan Green Belt and it is therefore much smaller than the wider metropolitan area.[citation needed]

As a selective grouping of relatively low-to-mid density (and some high density) output areas each consisting of roughly 120 households,[2] it can be compared to Greater London which covers 1,572 square kilometres (607 sq mi) and contained 8,173,194 residents at the time of the 2011 census.

The density of the two is similar — the density of the Greater London Built-Up Area is 8.3% higher than Greater London. All of both built-up areas is drained ultimately by the River Thames.
