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.

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 digital boundaries were created by the Great Britain Historical GIS Project and 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.

These digital boundaries can be used to map economic, social and demographic statistics from the Censuses of Population, 1911 to 1971, the Registrar-General's reports from the same period, and other relevant statistical sources. They can also be used as reference maps for these administrative units.

These units were aggregations of Local Government Districts and differed significantly from both Ancient Counties and the Registration Counties covered by earlier censuses. Difference include that the three Ridings of Yorkshire and the three Parts of Lincolnshire were separate Administrative Counties, as were East and West Suffolk, and East and West Sussex. The Isle of Ely and the Soke of Peterborough were also separate Administrative Counties until 1965, when Middlesex was also abolished as the County of London was expanded to become Greater London. The Isle of Wight was a separate Administrative County from Hampshire throughout the period.

The boundary data contain the same numerical identifiers as are included in the GBHD transcriptions of census and vital registration statistics for Administrative Counties, making statistical mapping straightforward.

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.

The Crop Map of England (CROME) is a polygon vector dataset mainly containing the crop types of England. The dataset contains approximately 32 million hexagonal cells classifying England into over 15 main crop types, grassland, and non-agricultural land covers, such as Woodland, Water Bodies, Fallow Land and other non-agricultural land covers. The classification was created automatically using supervised classification (Random Forest Classification) from the combination of Sentinel-1 Radar and Sentinel-2 Optical Satellite images during the period late October 2021 – September 2022. The dataset was created to aid the classification of crop types from optical imagery, which can be affected by cloud cover. The results were checked against survey data collected by field inspectors and visually validated. The data has been split into the Ordnance Survey Ceremonial Counties and each county is given a three letter code. Please refer to the CROME specification document to see which county each CODE label represents.

In 2023, London had a gross domestic product of over 569 billion British pounds, by far the most of any region of the United Kingdom. The region of South East England which surrounds London had the second-highest GDP in this year, at over 360 billion pounds. North West England, which includes the major cities of Manchester and Liverpool, had the third-largest GDP among UK regions, at almost 250 billion pounds. Levelling Up the UK London’s economic dominance of the UK can clearly be seen when compared to the other regions of the country. In terms of GDP per capita, the gap between London and the rest of the country is striking, standing at over 63,600 pounds per person in the UK capital, compared with just over 37,100 pounds in the rest of the country. To address the economic imbalance, successive UK governments have tried to implement "levelling-up policies", which aim to boost investment and productivity in neglected areas of the country. The success of these programs going forward may depend on their scale, as it will likely take high levels of investment to reverse economic neglect regions have faced in the recent past. Overall UK GDP The gross domestic product for the whole of the United Kingdom amounted to 2.56 trillion British pounds in 2024. During this year, GDP grew by 0.9 percent, following a growth rate of 0.4 percent in 2023. Due to the overall population of the UK growing faster than the economy, however, GDP per capita in the UK fell in both 2023 and 2024. Nevertheless, the UK remains one of the world’s biggest economies, with just five countries (the United States, China, Japan, Germany, and India) having larger economies. It is it likely that several other countries will overtake the UK economy in the coming years, with Indonesia, Brazil, Russia, and Mexico all expected to have larger economies than Britain by 2050.

London had the highest unemployment rate among regions of the United Kingdom in the first quarter of 2025 at ****percent, while for the UK as a whole, the unemployment rate was ****percent. Three other regions also had an unemployment rate higher than the national average, while Northern Ireland had the lowest unemployment rate in this time period, at ****percent. Labor market recovery after COVID-19 After reaching historically low levels of unemployment in 2019, there was a noticeable spike in the UK unemployment rate in the aftermath of the COVID-19 pandemic. After peaking at ****percent in late 2020, the unemployment rate declined throughout 2021 and 2022. High levels of job vacancies, resignations, and staff shortages in 2022, were all indicative of a very tight labor market that year, but all these measures have started to point in the direction of a slightly looser labor market. UK's regional economic divide While the North of England has some of the country’s largest cities, the sheer size and economic power of London is much larger than the UK's other urban agglomerations. Partly, due to the size of London, the United Kingdom is one of Europe’s most centralized counties, and there is a clear divide between the economic prospects of north and south England. In 2022, for example, the gross domestic product per head in London was ****** British pounds, far higher than the UK average of *******pounds, and significantly larger than North East England, the region with the lowest GDP per head at *******pounds.

In 2023/24 there were 116 homicide offences recorded in London, the most of any region of the United Kingdom during that time period. North West England, which includes the large city of Manchester had 71 homicides, and had the second-highest number of homicides. In the same reporting period, the constituent countries of Northern Ireland and Wales reported the fewest homicides, at 24 each. Homicides in the UK falling despite recent uptick Since 2002/03, all three jurisdictions of the UK; England and Wales, Scotland, and Northern Ireland, have seen their homicide rates fall, with Scotland seeing the steepest decline. The most significant decline in homicides in this period occurred between 2002/03 and 2014/15, which saw the annual number of homicides in England and Wales half from over 1,000 to 500. This trend was suddenly reversed from 2015/16 onwards, with homicides rising to around 700 per year between 2016/17 and 2019/20. While homicides fell back to 583 in 2023/24, it remains to be seen if this pattern will continue. Knives used in almost half of all murders In 2022/23 a knife or other sharp instrument was used in over 41 percent of all murders in England and Wales, making this, by far, the most common method of killing in that reporting year. The overall number of knife homicides reached 244 in 2022/23, compared with 282 in the previous year, and just above the 281 reported in 2017/18. Firearm homicides were much rarer than knife homicides, with 29 taking place in the same reporting year, and homicides caused by shooting only accounting for 4.9 percent of homicides overall.
