The population of the United Kingdom was estimated at almost 67.6 million people in 2022. It is the 21st most populated country in the world and has a population density of 279 people per square kilometre, with England having significantly greater density than Wales, Scotland, and Northern Ireland. Almost a third of the population lives in south east England, which is predominantly urban and suburban, with 8.9 million in the capital city, London, whose population density was 5,640 inhabitants per square kilometre (14,600/sq mi) in 2022.
The administrative geography of the United Kingdom is complex, multi-layered and non-uniform. The United Kingdom, a sovereign state to the northwest of continental Europe, consists of England, Northern Ireland, Scotland and Wales. For local government in the United Kingdom, England, Northern Ireland, Scotland and Wales each have their own system of administrative and geographic demarcation. Consequently, there is "no common stratum of administrative unit encompassing the United Kingdom".
Demographics of Wales include population, place of birth, age, ethnicity, religion, and number of marriages in Wales.
The demography of England has since 1801 been measured by the decennial national census, and is marked by centuries of population growth and urbanization. Due to the lack of authoritative contemporary sources, estimates of the population of England for dates prior to the first census in 1801 vary considerably. The population of England at the 2021 census was about 56,489,800.
The Office for National Statistics is the executive office of the UK Statistics Authority, a non-ministerial department which reports directly to the UK Parliament.
English, in various dialects, is the most widely spoken language of the United Kingdom, but a number of regional and migrant languages are also spoken. Regional indigenous languages are Scots and Ulster Scots and the Celtic languages, Irish, Scottish Gaelic, Welsh and, as a revived language with few speakers, Cornish. British Sign Language is also used. There are also many languages spoken by immigrants who arrived recently to the United Kingdom, mainly within inner city areas; these languages are mainly from continental Europe and South Asia.
GSS codes are nine-character geocodes maintained by the United Kingdom's Office for National Statistics (ONS) to represent a wide range of geographical areas of the UK, for use in tabulating census and other statistical data. GSS refers to the Government Statistical Service of which ONS is part.
A nationwide census, known as Census 2001, was conducted in the United Kingdom on Sunday, 29 April 2001. This was the 20th UK census and recorded a resident population of 58,789,194.
Coincident full censuses have taken place in the different jurisdictions of the United Kingdom every ten years since 1801, with the exceptions of 1941, Ireland in 1921/Northern Ireland in 1931, and Scotland in 2021. In addition to providing detailed information about national demographics, the results of the census play an important part in the calculation of resource allocation to regional and local service providers by the UK government.
White British is an ethnicity classification used for the indigenous White population identifying as English, Scottish, Welsh, Cornish, Northern Irish, or British in the United Kingdom Census. In the 2011 census, the White British population was 49,997,686, 81.5% of Great Britain's total population. For the United Kingdom entirely, due to different reporting measures within Northern Ireland which includes all those who identified as British with those who identified as Irish, an amalgamated total of 52,320,080 including those who identified as White Irish in Great Britain is given making up 82.8% of the population.
Since 1922, the United Kingdom has been made up of four countries: England, Scotland, Wales and Northern Ireland. The UK Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom.
Northern Ireland is the smallest of the four components of the United Kingdom in terms of both area and population, containing 2.9% of the total population and 5.7% of the total area of the United Kingdom. It is the smaller of the two political entities on the island of Ireland by area and population, the other being the Republic of Ireland. Northern Ireland contains 27.1% of the total population and 16.75% of the total area of the island of Ireland.
White Irish is an ethnicity classification used in the census in the United Kingdom for England, Scotland and Wales. In the 2021 census, the White Irish population was 564,342 or 0.9% of Great Britain's total population. This was a slight fall from the 2011 census which recorded 585,177 or 1% of the total population.
A census of the population of the United Kingdom is taken every ten years. The 2011 census was held in all counties 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.
A local information system (LIS) is a form of information system built with business intelligence tools, designed primarily to support geographic reporting. They overlap with some capabilities of geographic information systems (GIS), although their primary function is the reporting of statistical data rather than the analysis of geospatial data. LIS also tend to offer some common knowledge management functionality for storage and retrieval of unstructured data such as documents. They deliver functionality to load, store, analyse and present statistical data that has a strong geographic reference. In most cases the data is structured as indicators and is linked to discrete geographic areas, for example population figures for US counties or numbers claiming unemployment benefit across wards in England. The ability to present this data using data visualization tools like charts and maps is also a core feature of these systems.
Crime statistics in the United Kingdom refers to the data collected in the United Kingdom, and that collected by the individual areas, England and Wales, Scotland and Northern Ireland, which operate separate judicial systems. It covers data related to crime in the United Kingdom. As with crime statistics elsewhere, they are broadly divided into victim studies and police statistics. More recently, third-party reporting is used to quantify specific under-reported issues, for example, hate crime.
Beyond 2011, also known as The Beyond 2011 Programme, was a project initiated by the UK Statistics Authority to look at the alternatives to running a UK census in 2021. In 2008, the Treasury Select Committee had expressed concerns about the increasing cost of running the census and inaccuracies in data gathered only every ten years. In 2010 the newly elected coalition government reiterated such concerns responding to a report by the UK Statistics Authority.
The 2021 United Kingdom census is the 23rd official census of the United Kingdom. Beginning in 1801, they have been recorded every 10 years. The 2021 censuses of England, Wales, and Northern Ireland took place on 21 March 2021, and the census of Scotland took place 364 days 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. These were the first British censuses for which most of the data was gathered online. Two of them went ahead despite the COVID-19 pandemic, in part because the information obtained would assist government and public understanding of the pandemic's impact. The census-taking in Scotland was postponed, and took place in 2022 because of the pandemic.
The ONS Postcode Directory (ONSPD) relates both current and terminated postcodes in the United Kingdom to a range of current statutory administrative, electoral, health and other area geographies. It also links postcodes to pre-2002 health areas, 1991 Census enumeration districts for England and Wales, 2001 Census Output Areas (OA) and Super Output Areas (SOA) for England and Wales, 2001 Census OAs and SOAs for Northern Ireland and 2001 Census OAs and Data Zones (DZ) for Scotland. It helps support the production of area based statistics from postcoded data.
