The statistic shows the total population in the United Kingdom from 2015 to 2019, with projections up until 2025. The population grew steadily over this period.

Population of the United Kingdom

Despite a fertility rate just below the replacement rate, the United Kingdom’s population has been slowly but steadily growing, increasing by an average of 0.6 percent every year since 2002. The age distribution has remained roughly the same for the past ten years or so, with the share of the population over 65 years old seeing a slight increase as the baby boomer generation enters into that age bracket. That share is likely to continue growing slightly, as the United Kingdom has one of the highest life expectancies in the world.

The population of the island nation is predominantly white Christians, but a steady net influx of immigrants, part of a legacy of the wide-reaching former British Empire, has helped diversify the population. One of the largest ethnic minorities in the United Kingdom is that of residents of an Indian background, born either in the UK, India, or in other parts of the world. India itself is experiencing problems with rapid population growth, causing some of its population to leave the country in order to find employment. The United Kingdom’s relatively lower levels of unemployment and the historical connection between the two countries (which has also resulted in family connections between individuals) are likely reasons that make it a popular destination for Indian emigrants.

The total population in the United Kingdom was estimated at 68.3 million people in 2023, according to the latest census figures and projections from Trading Economics.

By 2043 the population of London is expected to reach 9.8 million people, an increase of 550,000 people when compared with 2025. While it has seen quite a steep rise in its population in recent years, London’s population was relatively stable 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 8.86 million by 2022. 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 57,338 pounds, compared with 33,593 pounds.

By 2043 it is expected that there will be approximately 4.99 million men and 4.82 million women living in London, compared with 4.66 million men and almost 4.6 million women in 2025. London’s population since 1981 Between 1981 and 1988, the population of London declined from 6.8 million, to 6.73 million. This period of gradual population decline was, however, followed by a sustained era of population growth, with London's population reaching a peak of 8.9 million in 2019. In the years since that peak, the population of the capital has declined slightly and, as of 2022, was 8.86 million. London's boroughs London is currently split up into 32 boroughs, as well as the historic center of the city, the City of London. The City of London had a population of just 10,847 people in 2022, compared with 392,224 in Croydon, the London Borough with the highest population that year. London's historic center also had the highest average weekly salary in the city, at 1,138 pounds, compared with 588 pounds in the Borough of Redbridge.

About this dataset

Context

The dataset tabulates the data for the England, AR population pyramid, which represents the England population distribution across age and gender, using estimates from the U.S. Census Bureau American Community Survey (ACS) 2019-2023 5-Year Estimates. It lists the male and female population for each age group, along with the total population for those age groups. Higher numbers at the bottom of the table suggest population growth, whereas higher numbers at the top indicate declining birth rates. Furthermore, the dataset can be utilized to understand the youth dependency ratio, old-age dependency ratio, total dependency ratio, and potential support ratio.

Key observations

• Youth dependency ratio, which is the number of children aged 0-14 per 100 persons aged 15-64, for England, AR, is 36.5.
• Old-age dependency ratio, which is the number of persons aged 65 or over per 100 persons aged 15-64, for England, AR, is 25.8.
• Total dependency ratio for England, AR is 62.3.

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.
