Historical dataset of population level and growth rate for the London, UK metro area from 1950 to 2025.

The population of London reached over **** million in 2024, an increase of almost *** million people when compared with the early 1980s. Throughout the 1980s, the population of the United Kingdom's capital grew at a relatively slow rate, before accelerating to a much faster rate in the 1990s. London is by far the largest city / urban agglomeration in the United Kingdom, more than three times larger than the next largest cities of Manchester and Birmingham. London’s forecasted population is expected to continue growing at much the same pace it has been growing since the mid-1990s and reach almost *** million by 2042. London boroughs As of 2024, the London borough with the highest population was Croydon, at approximately *******, followed by Barnet at *******. Overall, London is divided into 33 different boroughs, with London's historic center, the City of London, having by far the smallest population, at just ******. Residents of the City of London, however, have the highest average median weekly earnings among all of London's boroughs, at ***** pounds per week, compared with just *** pounds per week in Redbridge, the lowest average weekly earnings among London boroughs. While the overall unemployment rate for London was 5** percent in early 2025, this ranged from ****percent in Newham, to just *** percent in Richmond upon Thames.
Economic imbalance Aside from being the UK's largest city in terms of population, London is also undoubtedly the UK's cultural, political and economic center. As of 2023, the GDP of Greater London was approximately *** billion British pounds, almost a quarter of the UK's overall GDP. In the same year, GDP per person in London was ****** pounds compared with the UK average of ****** pounds. Additionally, productivity in London is far higher than the UK average. As measured by output per hour worked, London was **** percent more productive than the rest of the UK.

About this dataset

Context

The dataset tabulates the London population over the last 20 plus years. It lists the population for each year, along with the year on year change in population, as well as the change in percentage terms for each year. The dataset can be utilized to understand the population change of London across the last two decades. For example, using this dataset, we can identify if the population is declining or increasing. If there is a change, when the population peaked, or if it is still growing and has not reached its peak. We can also compare the trend with the overall trend of United States population over the same period of time.

Key observations

In 2023, the population of London was 10,533, a 0.74% increase year-by-year from 2022. Previously, in 2022, London population was 10,456, an increase of 0.61% compared to a population of 10,393 in 2021. Over the last 20 plus years, between 2000 and 2023, population of London increased by 1,802. In this period, the peak population was 10,533 in the year 2023. The numbers suggest that the population has not reached its peak yet and is showing a trend of further growth. Source: U.S. Census Bureau Population Estimates Program (PEP).

By 2047 the population of London is expected to reach 9.97 million people, an increase of almost 699,500 when compared with 2025. While there has been quite a steep rise in its population in recent years, London’s population growth was relatively stagnant throughout the 1980s and even decreased slightly towards the end of that decade. After peaking at 8.89 million in 2019, the population of London has fallen slightly, to 8.8 million by 2021. UK population forecast Like London, the population of the United Kingdom is forecast to continue to grow well into the middle of the century. By 2046, the population of the UK is estimated to be over 76.3 million people, an increase of over 20 million people when compared with the population figures for 1976. Additionally, the average age of the population is predicted to increase from 39.5 years in 2020 to 44.5 years by the mid-2040s, and continue to increase towards the end of the century. London looms large In the UK, London is by far the largest urban agglomeration in the country, dwarfing the UK's next largest cities of Birmingham, Manchester, and Leeds. London also has a dominant economic position in the UK, with the city accounting for around a quarter of the total GDP in the country. The UK capital also has a far higher GDP per head than the rest of the county, at over ****** pounds in 2023, compared with the UK average of ****** pounds.

Estimates of London's population between 1801 and 2021 (persons present 1801 to 1971 and usual residents for 1981 to 2021) derived from historic Census data.

Figures for years before 1931 are estimates by the Greater London Council published in Research Memorandum 413, 'The Changing Population of the London Boroughs'. Figures for 1931, 1951, and 1961 were published in 'Census 1961 Greater London Tables'; Figures for 1971 to 2021 are taken from individual censuses.

Estimates of London's population between 1801 and 2001 (persons present 1801 to 1991 and residents for 2001 onwards) derived from historic Census data.

Sources: years to 1971 - Greater London Council Research Memorandum 413, The Changing Population of the London Boroughs; 1981 Census Small Area Statistics, Table 1; 1991 Census Small Area Statistics, Table 1. Figure for Year-1939 is a mid-year estimate for the year 1939. Figure for Year-2001 onwards is the number of residents because the number of persons present is not available from 2001. Note that totals for Greater London may not match due to rounding errors. Figures are estimates to the nearest thousand.

In 2024, the population of the United Kingdom reached 69.3 million, compared with 68.5 million in 2023. The UK population has more than doubled since 1871 when just under 31.5 million lived in the UK and has grown by around 10.4 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 58.6 million people in 2024. By comparison, Scotland, Wales, and Northern Ireland had populations of 5.5 million, 3.2 million, and 1.9 million, respectively. Within England, South East England had the largest population, at over 9.6 million, followed by the UK's vast capital city of London, at almost 9.1 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.

Annual historical data for 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.

Between 1500 and 1800, London grew to be the largest city in Western Europe, with its population growing almost 22 times larger in this period. London would eventually overtake Constantinople as Europe's largest in the 1700s, before becoming the largest city in the world (ahead of Beijing) in the early-1800s.

The most populous cities in this period were the capitals of European empires, with Paris, Amsterdam, and Vienna growing to become the largest cities, alongside the likes of Lisbon and Madrid in Iberia, and Naples or Venice in Italy. Many of northwestern Europe's largest cities in 1500 would eventually be overtaken by others not shown here, such as the port cities of Hamburg, Marseilles or Rotterdam, or more industrial cities such as Berlin, Birmingham, and Munich.

United Kingdom Population: London data was reported at 8,825.001 Person th in 2017. This records an increase from the previous number of 8,769.659 Person th for 2016. United Kingdom Population: London data is updated yearly, averaging 7,154.000 Person th from Jun 1971 (Median) to 2017, with 47 observations. The data reached an all-time high of 8,825.001 Person th in 2017 and a record low of 6,729.000 Person th in 1988. United Kingdom Population: London data remains active status in CEIC and is reported by Office for National Statistics.

This project examines the crucial role of family and household in the social and economic transformations that took place in London in the sixteenth and seventeenth centuries. Population growth, immigration, urbanisation, and commercialisation produced new patterns of sociability, gender relations, employment, and domestic lifestyle. The family was central to all these developments, but has been little studied in detail. The project will reconstruct and analyse the dense matrix of families, households, properties, and buildings in sample areas of the capital, and trace their evolution over time, gaining new insights into social structures and the agents and circumstances of change.

The trend-based projections include a range of variants based on different assumptions about future levels of migration. The projections are produced for all local authorities in England & Wales and nationally for Scotland and Northern Ireland. The datasets include summary workbooks for London boroughs and detailed component of change outputs for all model areas.

The most recent set of trend-based population projections currently available are the 2020-based variant projections (September 2021).

The 2020-based projections comprise 4 principal variants which have been produced using different assumptions about future levels of domestic and international migration. Variant projections have been produced in order to assist users in understanding current uncertainty about future population growth. A full explanation of the differences between these projections is available in the supporting documentation.

Additionally, the trend-based projections also project the future number of households at local authority level by converting the projected population into households. Different sets of trend-based Household projections have been created using both the 2014-based DCLG household projection model and the 2018-based ONS household model so that users can compare the results of using these two different methodologies.

The Global Human Footprint dataset of the Last of the Wild Project, version 2, 2005 (LWPv2) is the Human Influence Index (HII) normalized by biome and realm. The HII is a global dataset of 1 km grid cells, created from nine global data layers covering human population pressure (population density), human land use and infraestructure (built-up areas, nighttime lights, land use/land cover) and human access (coastlines, roads, navigable rivers).The Human Footprint Index (HF) map, expresses as a percentage the relative human influence in each terrestrial biome. HF values from 0 to 100. A value of zero represents the least influence -the "most wild" part of the biome with value of 100 representing the most influence (least wild) part of the biome.

In 2024, the population of the United Kingdom was estimated to have grown by approximately 1.1 percent, with the population growing fastest in North West England, which grew by 1.4 compared with 2023. By contrast, growth in Scotland, Wales and Northern Ireland was below the UK average, with the population in these countries growing by 0.7 percent, 0.6 percent, and 0.4 percent respectively. Four countries of the UK Within the UK, South East England had the highest population of the regions that comprise the United Kingdom, at more than 9.6 million people. In terms of the four countries of the UK, England had by far the highest population at over 58.6 million people, compared with Scotland (5.5 million) Wales (3.2 million) and Northern Ireland (1.9 million) which have comparatively smaller populations. Of these countries, Scotland was the most sparsely populated, with 71 people per square kilometer, compared with 5,782 people per square km in London. Largest cities in the UK With over nine million people living there, London is by some distance the largest city in the UK. Other large cities in the UK include the West Midlands urban area, centered around the city of Birmingham, as well as Greater Manchester in North West England. With similar populations of around three million people, these two cities, generally considered as the main contenders for being England's second-city. In this year, Scotland's largest city was Glasgow, with Cardiff being the biggest settlement in Wales, and Belfast the largest in Northern Ireland.
