Office for National Statistics in the context of "Broad measures of economic progress"

The 2021–2022 United Kingdom censuses collectively comprised the 23rd census of the United Kingdom.

The censuses of England and Wales, and Northern Ireland took place on 21 March 2021, and the census of Scotland took place later on 20 March 2022. The censuses were administered by the Office for National Statistics (ONS) in England and Wales, by the Northern Ireland Statistics and Research Agency (NISRA) in Northern Ireland, and by the National Records of Scotland in Scotland.

This is a list of the most populous urban areas in the United Kingdom based on the 2011 census, as defined by the Office for National Statistics (ONS). As of July 2025, the ONS has not published the equivalent data based on the 2021 census.

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 the Greater Brighton City Region that was created in 2014 from seven local authorities in Sussex covers a much larger area. The conurbation dominates West and East Sussex, with around one in three 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. The Brighton/Worthing/Littlehampton conurbation was the largest on the Channel before Portsmouth and Southampton's conurbations were combined for much official data analysis after the 2011 census.

This conurbation is also the UK's most densely populated major conurbation outside London with 5,304 inhabitants per square kilometre (13,740/sq mi). 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.

The Greater Manchester Built-up Area is an area of land defined by the Office for National Statistics (ONS), consisting of the large conurbation that encompasses the urban element of the city of Manchester and the metropolitan area that forms much of Greater Manchester in North West England. According to the United Kingdom Census 2011, the Greater Manchester Built-up Area has a population of 2,553,379 making it the second most populous conurbation in the United Kingdom after the Greater London Built-up Area. This was an increase of 14% from the population recorded at the United Kingdom Census 2001 of 2,240,230, when it was known as the Greater Manchester Urban Area.

The Greater Manchester Built-up Area is not conterminous with Greater Manchester, a metropolitan county of the same name (and, until 1974, part of the counties of Lancashire, Cheshire and Yorkshire) for it excludes settlements such as Wigan and Marple from Greater Manchester, but includes hinterland settlements which lie outside its statutory boundaries, such as Wilmslow in Cheshire, Glossop in Derbyshire, Whitworth in Lancashire and Newton-le-Willows in Merseyside.

A census of the population of the United Kingdom is taken every ten years. The 2011 census was held in all countries of the UK on 27 March 2011. It was the first UK census which could be completed online via the Internet. The Office for National Statistics (ONS) is responsible for the census in England and Wales, the General Register Office for Scotland (GROS) is responsible for the census in Scotland, and the Northern Ireland Statistics and Research Agency (NISRA) is responsible for the census in Northern Ireland.

The Office for National Statistics is the executive office of the UK Statistics Authority, a non-ministerial department formed in 2008 and which reports directly to Parliament. ONS is the UK Government's single largest statistical producer of independent statistics on the UK's economy and society, used to assist the planning and allocation of resources, policy-making and decision-making. ONS designs, manages and runs the census in England and Wales. In its capacity as the national statistics office for the United Kingdom, ONS also compiles and releases census tables for the United Kingdom when the data from England and Wales, Scotland and Northern Ireland are complete.

Hungarians in the United Kingdom (Hungarian: Magyarok az Egyesült Királyságban [ˈmɒɟɒrok ˈɒz ˈɛɟːɛʃylt ˈkiraːjʃaːɡbɒn]) include Hungarian-born immigrants to the UK and their descendants, of whom there are a substantial number. Since Hungary joined the European Union in 2004, the UK's Hungarian population has grown significantly. Although official ONS estimates are that there were about 98,000.

Jarrow (/ˈdʒæroʊ/ or /ˈdʒærə/) is a town in South Tyneside in the county of Tyne and Wear, England. Historically in County Durham, it is on the south bank of the River Tyne, about three miles (five kilometres) from the east coast. It is home to the southern portal of the Tyne Tunnel and five miles (eight kilometres) east of Newcastle upon Tyne. At the 2021 census the Jarrow built up area as defined by the Office for National Statistics had a population of 29,470.

In the eighth century, St Paul's Monastery in Jarrow (now Monkwearmouth–Jarrow Abbey) was the home of the Venerable Bede, who is regarded as the greatest Anglo-Saxon scholar and the father of English history. The town is part of the historic County Palatine of Durham. From the middle of the 19th century until 1935, Jarrow was a centre for shipbuilding, and was the starting point of the Jarrow March against unemployment in 1936.
