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 on 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". 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 Combined Southampton and Portsmouth conurbation (However, Brighton ranked first on this list before Portsmouth and Southampton's conurbations were combined into one after the 2011 census)
The Brighton/Worthing/Littlehampton conurbation is also the UK's most densely populated major conurbation outside of London with 5304 people per km². This is primarily due to its tight boundaries between the South Downs national park to the north, and the English Channel to the south.
It is a multi-centred conurbation and the city of Brighton and Hove contributes just over half the population of the conurbation.
The conurbation's population is made up of the following settlements from west to east as defined by the Office for National Statistics:
Places in the conurbation
The conurbation contains the following places, from west to east along the coast. 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.
|Urban Subdivision||Population (2001 census)||Population (2011 census)|
|Brighton and Hove||229,700|
- Hove and Brighton were separate subdivisions for the 2001 census but are combined in one Brighton and Hove subdivision for the 2011 census.
- In the 2011 census the Shoreham subdivision includes Sompting and Lancing.
- Findon was not included as part of the Brighton and Hove built-up area for the 2011 census.
- Saltdean and Rottingdean were not included as part of the Brighton and Hove built-up area for the 2011 census and instead form a built-up area called Saltdean/Woodingdean with a population of 22,729.
- In the 2001 census the Littlehampton subdivision included Angmering and Ferring. In the 2011 census the Littlehampton subdivision still includes Angmering but Ferring is part of the Worthing subdivision.
There are some small gaps that help maintain distinct identities of places in the conurbation, although in places, the settlements coalesce:
- Goring Gap between Ferring and Goring/Worthing
- Sompting Gap between Worthing and Sompting
- Brooklands Park between Worthing and Lancing
- Lancing Gap between Lancing and Shoreham
Settlements very close to the conurbation but not included in the official statistics include the towns of Peacehaven (separated from Brighton by Telscombe Tye, a small open space), Newhaven (joined to Peacehaven, population 11,000) and Seaford (separated from Newhaven by the River Ouse, population 22,000).
