The Brighton and Hove Built-up area or Brighton/Worthing/Littlehampton conurbation has a population of 474,485 (2011 census), making it England's 12th largest conurbation. This was an increase of around 3% from the 2001 population of 461,181. Named the Brighton/Worthing/Littlehampton conurbation by the Office for National Statistics for the 2001 census and Brighton and Hove Built-up area for the 2011 census, the area has also been known as "Greater Brighton" (although Greater Brighton can include Lewes). The conurbation dominates West and East Sussex, with around 1 in 3 of Sussex's population living within its boundaries. It is also the second largest conurbation in the South East region of England and the second largest conurbation on the English Channel coast, in either England or France. In both of these cases the Brighton conurbation trails the Southampton and Portsmouth conurbation. This identified conurbation was the largest on the Channel before Portsmouth and Southampton's conurbations were combined for much official data analysis after the 2011 census.
The Brighton/Worthing/Littlehampton conurbation is also the UK's most densely populated major conurbation outside London with 5304 people per km². This is due to its tight boundaries between the South Downs national park to the north, and the English Channel to the south together with less land devoted to domestic gardens in English seaside towns than in inland towns.
It is a multi-centred conurbation and the eastern part, the city of Brighton and Hove, has approximately half of its population.
The total distance in a straight line from the western edge of Littlehampton to the eastern edge of Saltdean is between 23 and 24 miles. Along the shore or by road, it is slightly further.
The conurbation's population is made up of the following settlements as defined by the Office for National Statistics:
