National and subnational mid-year population estimates for the UK and its constituent countries by administrative area, age and sex (including components of population change, median age and population density).

The population of the United Kingdom in 2023 was estimated to be approximately 68.3 million in 2023, with almost 9.48 million people living in South East England. London had the next highest population, at over 8.9 million people, followed by the North West England at 7.6 million. With the UK's population generally concentrated in England, most English regions have larger populations than the constituent countries of Scotland, Wales, and Northern Ireland, which had populations of 5.5 million, 3.16 million, and 1.92 million respectively. English counties and cities The United Kingdom is a patchwork of various regional units, within England the largest of these are the regions shown here, which show how London, along with the rest of South East England had around 18 million people living there in this year. The next significant regional units in England are the 47 metropolitan and ceremonial counties. After London, the metropolitan counties of the West Midlands, Greater Manchester, and West Yorkshire were the biggest of these counties, due to covering the large urban areas of Birmingham, Manchester, and Leeds respectively. Regional divisions in Scotland, Wales and Northern Ireland The smaller countries that comprise the United Kingdom each have different local subdivisions. Within Scotland these are called council areas whereas in Wales the main regional units are called unitary authorities. Scotland's largest Council Area by population is that of Glasgow City at over 622,000, while in Wales, it was the Cardiff Unitary Authority at around 372,000. Northern Ireland, on the other hand, has eleven local government districts, the largest of which is Belfast with a population of around 348,000.

In 2023, the population of the United Kingdom reached 68.3 million, compared with 67.6 million in 2022. The UK population has more than doubled since 1871 when just under 31.5 million lived in the UK and has grown by around 8.2 million since the start of the twenty-first century. For most of the twentieth century, the UK population steadily increased, with two noticeable drops in population occurring during World War One (1914-1918) and in World War Two (1939-1945). Demographic trends in postwar Britain After World War Two, Britain and many other countries in the Western world experienced a 'baby boom,' with a postwar peak of 1.02 million live births in 1947. Although the number of births fell between 1948 and 1955, they increased again between the mid-1950s and mid-1960s, with more than one million people born in 1964. Since 1964, however, the UK birth rate has fallen from 18.8 births per 1,000 people to a low of just 10.2 in 2020. As a result, the UK population has gotten significantly older, with the country's median age increasing from 37.9 years in 2001 to 40.7 years in 2022. What are the most populated areas of the UK? The vast majority of people in the UK live in England, which had a population of 57.7 million people in 2023. By comparison, Scotland, Wales, and Northern Ireland had populations of 5.44 million, 3.13 million, and 1.9 million, respectively. Within England, South East England had the largest population, at over 9.38 million, followed by the UK's vast capital city of London, at 8.8 million. London is far larger than any other UK city in terms of urban agglomeration, with just four other cities; Manchester, Birmingham, Leeds, and Glasgow, boasting populations that exceed one million people.

In 2023, almost nine million people lived in Greater London, making it the most populated ceremonial county in England. The West Midlands Metropolitan County, which contains the large city of Birmingham, was the second-largest county at 2.98 million inhabitants, followed by Greater Manchester and then West Yorkshire with populations of 2.95 million and 2.4 million, respectively. Kent, Essex, and Hampshire were the three next-largest counties in terms of population, each with around 1.89 million people. A patchwork of regions England is just one of the four countries that compose the United Kingdom of Great Britain and Northern Ireland, with England, Scotland and Wales making up Great Britain. England is therefore not to be confused with Great Britain or the United Kingdom as a whole. Within England, the next subdivisions are the nine regions of England, containing various smaller units such as unitary authorities, metropolitan counties and non-metropolitan districts. The counties in this statistic, however, are based on the ceremonial counties of England as defined by the Lieutenancies Act of 1997. Regions of Scotland, Wales, and Northern Ireland Like England, the other countries of the United Kingdom have their own regional subdivisions, although with some different terminology. Scotland’s subdivisions are council areas, while Wales has unitary authorities, and Northern Ireland has local government districts. As of 2022, the most-populated Scottish council area was Glasgow City, with over 622,000 inhabitants. In Wales, Cardiff had the largest population among its unitary authorities, and in Northern Ireland, Belfast was the local government area with the most people living there.

As of 2023, the population density in London was by far the highest number of people per square km in the UK, at 5,690. Of the other regions and countries which constitute the United Kingdom, North West England was the next most densely populated area at 533 people per square kilometer. Scotland, by contrast, is the most sparsely populated country or region in the United Kingdom, with only 70 people per square kilometer. UK population over 67 million According to the official mid-year population estimate, the population of the United Kingdom was just almost 67.6 million in 2022. Most of the population lived in England, where an estimated 57.1 million people resided, followed by Scotland at 5.44 million, Wales at 3.13 million and finally Northern Ireland at just over 1.9 million. Within England, the South East was the region with the highest population at almost 9.38 million, followed by the London region at around 8.8 million. In terms of urban areas, Greater London is the largest city in the United Kingdom, followed by Greater Manchester and Birmingham in the North West and West Midlands regions of England. London calling London's huge size in relation to other UK cities is also reflected by its economic performance. In 2021, London's GDP was approximately 494 billion British pounds, almost a quarter of UK GDP overall. In terms of GDP per capita, Londoners had a GDP per head of 56,431 pounds, compared with an average of 33,224 for the country as a whole. Productivity, expressed as by output per hour worked, was also far higher in London than the rest of the country. In 2021, London was around 33.2 percent more productive than the rest of the country, with South East England the only other region where productivity was higher than the national average.

The Great Britain Historical Database has been assembled as part of the ongoing Great Britain Historical GIS Project. The project aims to trace the emergence of the north-south divide in Britain and to provide a synoptic view of the human geography of Britain at sub-county scales. Further information about the project is available on A Vision of Britain webpages, where users can browse the database's documentation system online.

These data were originally collected by the Censuses of Population for England and Wales, and for Scotland. They were computerised by the Great Britain Historical GIS Project and its collaborators.

The census has gathered data on "occupations", meaning individuals' roles in the workplace, since the first household enumeration in 1841, and this collection includes most of the published results. However, how the results were classified varied greatly: for 1841, there is simply an alphabetical list of individual occupations, in 1851 the most basic classification was into workers in animal, vegetable and minerals, and so on. Further, the more detailed the occupational classification used, space considerations tended to require a less detailed geography; or, sometimes, the use of an abridged classification for small towns and rural areas; or even different tables and classifications for men and for women. There are consequently multiple datasets for some years.

Latest edition information

For the second edition (October 2022), the data and documentation have been revised.

Main Topics:

Occupations, meaning self-described roles in the workplace, tabulated by gender using a variety of occupational classifications. Note that the early classifications often mingle notions of social status. From 1931 onwards these tables also include counts of the unemployed.

Please note: this study does not include information on named individuals and would therefore not be useful for personal family history research.

Daytime/workday population

England and Wales (Workday Population)

Workday population is where the usually resident population is re-distributed to their places of work, while those not in work are recorded at their usual residence.

The workday population of an area is defined as all usual residents aged 16 and above who are in employment and whose workplace is in the area, and all other usual residents of any age who are not in employment but are resident in the area. People who work mainly at or from home or do not have a fixed place of work are included in their area of their usual residence. The following population groups are excluded from the workday population of an area:

• Those living in England and Wales but working in Scotland, Northern Ireland, outside the UK or on offshore installations,
• Those with a place of work in England and Wales but who are not usually resident in England and Wales, and
• Short-term residents

England and Wales (Workplace Population)

Workplace population is where the usually resident population is re-distributed to their main place of work, but those not working are excluded.

Northern Ireland (Daytime Population)

The daytime population of an area is defined as 'All usual residents who are either in employment or full-time students in the area, or not in employment or full-time students but are usually resident in the area'. People who work or study mainly at or from home, or do not have a fixed place of work or study, are included in the area of their usual residence.

The following population groups are excluded from the daytime population of an area:

• Those living in Northern Ireland but working or studying in England, Wales, Scotland, outside the UK or on offshore installations
• Those with a place of work or study in Northern Ireland but who are not usually resident in Northern Ireland

Industry

The industry in which a person aged 16 and over works relates to their main job, and is derived from information provided on the main activity of their employer or business. This is used to assign responses to an industry code based on the UK Standard Industrial Classification of Economic Activities 2007 (UK SIC 2007).

These data were originally collected by the Censuses of Population for England and Wales, and for Scotland. They were computerised by the Great Britain Historical GIS Project and its collaborators. They form part of the Great Britain Historical Database, which contains a wide range of geographically-located statistics, selected to trace the emergence of the north-south divide in Britain and to provide a synoptic view of the human geography of Britain, generally at sub-county scales.

The Census of Population first gathered data on housing "density", i.e. the number of persons in each household relative to the number of rooms, in 1891, although the first year included here is 1901. In 1891, over-crowding was defined as over 2 persons per room; by 1931 this threshold had dropped to 1.5 persons; and by 1961 to 1 person per room. Up to 1931, the data for each locality and date form a table of numbers of persons against numbers of rooms, and these transcriptions sometimes exclude the rows/columns for the very largest households (see the documentation for individual tables). From 1951 onwards, simpler tables simply list numbers of households in each density category (e.g. over 1 person per room and not more than 1.5 persons).

This is a new edition. Data have been added for 1911 and 1951. Wherever possible, ID numbers have been added for counties and districts which match those used in the digital boundary data created by the GBH GIS, greatly simplifying mapping.

The population of England was estimated to have reached almost 57.7 million in 2023, compared with 53.9 million ten years earlier in 2013. Compared with 1971, the population of England has grown by over ten million.

This computerised transcription of the census enumerators' books for the 1881 Census for England, Scotland and Wales, the Channel Islands and the Isle of Man is a by-product of a project to create a microfiche index of the population of Great Britain for genealogists. Covering the entire enumerated population of England, Scotland and Wales, the Channel Islands and the Isle of Man in 1881, it is the largest collection of historical source material to be made available in computerised form. The data consists of the name, address, relationship to the head of household, marital status, age, occupation and birthplace of some 26 million individuals, together with information about disabilities.
In 1999 the Genealogical Society of Utah published a version of this computerised transcription as a CD-ROM product suitable for genealogical research (Genealogical Society of Utah (1999) 1881 British census and national index. [25 CDs]. Salt Lake City, Utah: GSU). This study is an enriched version of these data. The sample is a 5 per cent random sample of the parishes of Great Britain. The sample was chosen in the simplest manner possible. A list of all the parishes in England, Wales, Scotland and the Islands in the British Seas was created; using a random number generator in Microsoft Excel, a random number between zero and one was allocated to each parish. All those less than or equal to 0.05 were selected for the sample. The records relating to the individuals in each of these parishes were then extracted from the data and combined in a database.

Tables B1 and B3 in Appendix B of the documentation list the 716 parishes in the sample.

UK residents by broad country of birth and citizenship groups, broken down by UK country, local authority, unitary authority, metropolitan and London boroughs, and counties. Estimates from the Annual Population Survey.

Table shows estimates of resident population by 5 year age band from the 2011 Census of England and Wales, Scotland and Northern Ireland.

England Wales local authorities, counties and regions, plus districts of Scotland and Northern Ireland and total UK population are included.

1) For the 2011 Census, a usual resident of the UK is anyone who, on census day 2011, was in the UK and had stayed or intended to stay in the UK for a period of 12 months or more, or had a permanent UK address and was outside the UK and intended to be outside the UK for less than 12 months.

2) The age of a person is derived from their date of birth. It is their age in years on their last birthday up to and including census day 2011. Dates of birth that imply an age over 115 are treated as invalid and the person's age is imputed.

3) Council area boundaries as at 1 April 2011.

4) Scotland figures in this table may not add exactly because they have been rounded to the nearest hundred.

5) Scotland has not published data by 5 year bands above 80, so all people aged 80+ are included in the 80-84 age group.
