In 2020/21 there were approximately 696,000 Polish nationals living in the United Kingdom, the highest non-British population at this time. Indian and Irish were the joint second-largest nationalities at approximately 370,000 people.

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.

To ensure that the NHS is held to account for doing all that it can to prevent avoidable deaths in older people. This indicator captures all persons aged 75 and over. A correction was made to this indicator on the 6th March 2019 due to errors found in the data. The confidence intervals for females in the region breakdown for the 2015-17 time period were displayed the wrong way round and some of the upper intervals were rounded incorrectly. These have now been corrected. A further correction was made to this indicator on the 21st May 2020. For 2015-17, The population numbers presented within the local authority (LA) breakdown for females were found to be incorrect for three LAs. The affected LAs were Redcar and Cleveland (E06000003), Norwich (E07000148) and Redbridge (E09000026). These have now been corrected. The indicator value and confidence intervals for all three LAs were unaffected by the error. Legacy unique identifier: P01728

The Active Lives Children and Young People Survey, which was established in September 2017, provides a world-leading approach to gathering data on how children engage with sport and physical activity. This school-based survey is the first and largest established physical activity survey with children and young people in England. It gives anyone working with children aged 5-16 key insight to help understand children's attitudes and behaviours around sport and physical activity. The results will shape and influence local decision-making as well as inform government policy on the PE and Sport Premium, Childhood Obesity Plan and other cross-departmental programmes. More general information about the study can be found on the Sport England Active Lives Survey webpage and the Active Lives Online website, including reports and data tables.

The Active Lives Children and Young People Survey, 2017-2018 commenced during school academic year 2017 / 2018. It ran from autumn term 2017 to summer term 2018 and excludes school holidays. The survey identifies how participation varies across different activities and sports, by regions of England, between school types and terms, and between different demographic groups in the population. The survey measures levels of activity (active, fairly active and less active), attitudes towards sport and physical activity, swimming capability, the proportion of children and young people that volunteer in sport, sports spectating, and wellbeing measures such as happiness and life satisfaction. The questionnaire was designed to enable analysis of the findings by a broad range of variables, such as gender, family affluence and school year.

The following datasets are available:

1) Main dataset includes responses from children and young people from school years 3 to 11, as well as responses from parents of children in years 1-2. The parents of children in years 1-2 provide behavioural answers about their child's activity levels, they do not provide attitudinal information. Using this main dataset, full analyses can be carried out into sports and physical activity participation, levels of activity, volunteering (years 5 to 11), etc. Weighting is required when using this dataset (wt_gross / wt_set1.csplan).

2) Year 1-2 pupil dataset includes responses from children in school years 1-2 directly, providing their attitudinal responses (e.g. whether they like playing sport and find it easy). Analysis can be carried out into feelings towards swimming, enjoyment for being active, happiness etc. Weighting is required when using this dataset (wt_gross / wt_set1.csplan).

3) Teacher dataset includes responses from the teachers at schools selected for the survey. Analysis can be carried out into school facilities available, length of PE lessons, whether swimming lessons are offered, etc. Weighting was formerly not available, however, as Sport England have started to publish the Teacher data, from December 2023 we decide to apply weighting to the data. The Teacher dataset now includes weighting by applying the ‘wt_teacher’ weighting variable.

For further information about the variables available for analysis, and the relevant school years asked survey questions, please see the supporting documentation. Please read the documentation before using the datasets.

Latest edition information

For the second edition (January 2024), the Teacher dataset now includes a weighting variable (‘wt_teacher’). Previously, weighting was not available for these data.

Main Topics:

Topics covered in the Active Lives Children and Young People Survey include:

• Sport and physical activity participation
• Well-being
• Health

The Mental Health of Children and Young People Surveys (MHCYP) series provides data about the mental health of young people living in Great Britain.

The MHCYP was first carried out in 1999, capturing information on 5 to 15-year-olds. It was conducted by the Office for National Statistics (ONS) on behalf of the Department of Health (now known as the Department of Health and Social Care, or DHSC), The Scottish Health Executive and the National Assembly for Wales. The following survey in the series was conducted in 2002 and focused on children looked after by their local authority. The third survey was conducted in 2004 and collected information from 5 to 16-year-olds. Follow-ups to this survey were conducted after 6 months and again after 3 years.

NHS Digital commissioned the 2017 survey on behalf of the DHSC. It collected information on 2 to 19-year-olds living in England. The survey was carried out by a consortium led by NatCen Social Research, which included the ONS and Youth In Mind.

The MHCYP 2020 survey was a Wave 1 follow-up to the 2017 survey and was conducted under the COVID-19 Public Health Directions 2020, as directed by the then Secretary of State for Health. The Wave 2 follow-up was conducted in 2021.

Further information can be found on the NHS Digital Mental Health of Children and Young People Surveys webpage.

A similar series covering adults, the Adult Surveys of Psychiatric Morbidity, is also commissioned by NHS Digital.

The Mental Health of Children and Young People in England, 2021: Special Licence Access (MHCYP) is the second in a series of follow-up surveys to the MHCYP 2017 survey (see SN 8467). The 2021 MHCYP was funded by the Department of Health and Social Care and commissioned by NHS England. The survey was carried out by the National Centre for Social Research (NatCen Social Research), the Office for National Statistics, the University of Cambridge and the University of Exeter.

The MHCYP surveys provide England's Official Statistics on trends in child mental health. The MHCYP 2017 was conducted face-to-face and involved data collection from a random sample of children and young people (aged 2 to 19 years). MHCYP 2017 participants who agreed to be re-contacted for future research were invited to take part in the MHCYP 2020 follow-up survey. In the 2020 survey, participants were asked to confirm that they were happy to continue to be re-contacted for future research. Therefore, the achieved MHCYP 2021 sample for this (Wave 2) follow-up was based on 3,667 children and young people (now aged 6 to 23 years) who took part in MHCYP 2017.

The three main aims of MHCYP 2021 were:

• to compare mental health between 2017 and 2020 - the likelihood of a mental disorder was assessed against completion of the Strengths and Difficulties Questionnaire (SDQ) in both years;
• to describe life during the COVID-19 pandemic;
• to present more detailed data on the mental health, circumstances and experiences of children and young people by ethnic group during the COVID-19 pandemic (where sample sizes allow).

In 2023, there were estimated to be around 4.01 million people aged between 30 and 34 living in England, the most of any age group. Those aged 35 to 39 comprised the next highest age group, at 3.95 million, while the age group with the fewest people was among those aged 90 and over.

As part of a project exploring the impact of Thatcherite social and economic policies on the lives of British people, we have merged together key variables from the British Cohort Study so that longitudinal data analyses over several years and decades are more easily available. The variables included relate to housing, schooling, employment, offending and victimisation, welfare, social and political attitudes and similar variables. This exercise was repeated for the National Child Development Study so as to provide a point of comparison. The data are not being made available here, but we have provided a narrative count of how we merged these two longitudinal data sets so that each data set had a longitudinal version of some of the data from birth to the year 2012.

This grant follows on from two earlier ESRC-funded grants held by Stephen Farrall, and a British Academy seminar he co-organised with Colin Hay (a leading theorist of Thatcherism). The first grant was a scoping project, which assessed the extent to which it was possible to undertake more prolonged and in-depth investigations into the social, economic and cultural impacts of Thatcherite public policy on contemporary UK society, especially as these features relate to criminal justice policy. This earlier grant concluded that it was possible to undertake two further projects. The first of these (looking at regional level changes using repeated cross-sectional surveys) we have, with ESRC-funding, completed. The second project (and the one we are seeking funding for herein) would extend this enquiry to the individual level using longitudinal data (thereby ensuring that we do not fall foul of committing the ecological fallacy - that is assuming that because something operates at the national level, it also works in the same way for individuals). To do this we will use data from the British Cohort Study which is a longitudinal study of a group of men and women born in one week in 1970. The cohort (which numbers over 17,000 people) have been interviewed themselves on a number of times (at ages 10, 16, 21, 26, 29, 34, 38 and 42) and there have been interviews with their mothers and teachers when they were younger. They were asked a range of questions about their home lives, schooling, employment careers, social attitudes and, crucially for us, since we are interested in how these processes lead people to or away from crime, their victimisation, drug taking, arrest history and offending. We have spent a long time theorising how the social and economic policies of the 1980s and 1990s might have operated to alter the social environments in which these young people grew up. Moreover, our analyses of changes in social attitudes in the country at the time and the extent to which these may have differed between generations allows us to 'locate' this cohort's experiences and values in wider contexts. By relying, where and when appropriate to do so, on a similar cohort study which went before this one (the National Child Development Study, participants born in 1958), we can disentangle the complex changes which occur as people age. This means that we are much less likely to misinterpret what looks like significant changes, but which are just a facet of aging and 'growing up'.

In 2023, there were estimated to be 956,116 people who were aged 35 in the United Kingdom, the most of any age in this year. The two largest age groups during this year were 30-34, and 35 to 39, at 4.7 million and 4.64 million people respectively. There is also a noticeable spike of 693,679 people who were aged 76, which is due to the high number of births that followed in the aftermath of the Second World War. Over one million born in 1964 In post-war Britain, there have only been two years when the number of live births was over one million, in 1947 and in 1964. The number of births recorded in the years between these two years was consistently high as well, with 1955 having the fewest births in this period at 789,000. This meant that until relatively recently, Baby Boomers were the largest generational cohort in the UK. As of 2022, there were approximately 13.76 million Baby Boomers, compared with 14 million in Generation X, 14.48 million Millennials, and 12.9 million members of Gen Z. The youngest generation in the UK, Generation Alpha numbered approximately 7.5 million in the same year. Median age to hit 44.5 years by 2050 The population of the United Kingdom is aging at a substantial rate, with the median age of the population expected to reach 44.5 years by 2050. By comparison, in 1950 the average age in the United Kingdom stood at 34.9 years. This phenomenon is not unique to the United Kingdom, with median age of people worldwide increasing from 23.6 years in 1950 to a forecasted 41.9 years by 2100. As of 2022, the region with the oldest median age in the UK was South West England, at 43.9 years, compared with 35.9 in London, the region with the youngest median age.

Thursday 2 February 2012 note: This 2010 data has now been superseded by 2011 data This publication contains information about populations registered with GP practices at Strategic Health Authority (SHA) and Primary Care Organisation (PCO) level in five-year age bands by gender, for England and Wales. The data was collected in April 2010 for GP relevant populations. They have been constrained to the Office for National Statistics 2009 mid-year population estimates - based on the 2001 Census, excluding some special populations. This reconciliation is carried out as the number of patient registrations is greater than the number of people living in England and Wales according to population estimates from the ONS. There may be a number of reasons for this, e.g. people leaving the country and not notifying their GP. The data are available in the spreadsheet as population figures by SHA and PCO, gender and in five-year age bands. Further information on how the data were collected and analysed is provided in the technical note. For more information on ONS population estimates, please see the Office for National Statistics website.

The English Housing Survey (EHS) is a continuous national survey commissioned by the Ministry of Housing, Community and Local Government (MHCLG) that collects information about people's housing circumstances and the condition and energy efficiency of housing in England. The EHS brings together two previous survey series into a single fieldwork operation: the English House Condition Survey (EHCS) (available from the UK Data Archive under GN 33158) and the Survey of English Housing (SEH) (available under GN 33277). The EHS covers all housing tenures. The information obtained through the survey provides an accurate picture of people living in the dwelling, and their views on housing and their neighbourhoods. The survey is also used to inform the development and monitoring of the Ministry's housing policies. Results from the survey are also used by a wide range of other users including other government departments, local authorities, housing associations, landlords, academics, construction industry professionals, consultants, and the general public.

The EHS has a complex multi-stage methodology consisting of two main elements; an initial interview survey of around 12,000 households and a follow-up physical inspection. Some further elements are also periodically included in or derived from the EHS: for 2008 and 2009, a desk-based market valuation was conducted of a sub-sample of 8,000 dwellings (including vacant ones), but this was not carried out from 2010 onwards. A periodic follow-up survey of private landlords and agents (the Private Landlords Survey (PLS)) is conducted using information from the EHS interview survey. Fuel Poverty datasets are also available from 2003, created by the Department for Energy and Climate Change (DECC).

The EHS interview survey sample formed part of the Integrated Household Survey (IHS) (available from the Archive under GN 33420) from April 2008 to April 2011. During this period the core questions from the IHS formed part of the EHS questionnaire.

End User Licence and Special Licence Versions:
From 2014 data onwards, the End User Licence (EUL) versions of the EHS will only include derived variables. In addition the number of variables on the new EUL datasets has been reduced and disclosure control increased on certain remaining variables. New Special Licence versions of the EHS will be deposited later in the year, which will be of a similar nature to previous EHS EUL datasets and will include derived and raw datasets.

Further information about the EHS and the latest news, reports and tables can be found on the GOV.UK English Housing Survey web pages.

The English Housing Survey, 2012-2013: Household Data comprises the full interview data (plus associated derived variables) for all cases where an interview has been completed. Datasets are provided for single financial years together with annual weights. The survey consists of a detailed interview using a CAPI based program. An interview is first conducted with the householder. General topics and concepts covered include general tenure and demographics, household income and housing costs, housing needs, housing aspirations and satisfaction, housing moves, and vulnerable and disadvantaged households.

The household data should be used for any analysis where only information from the household interview is required. Users who also require data from the physical survey should use the English Housing Survey, 2012: Housing Stock Data (SN 7511).

The Opinions and Lifestyle Survey (OPN) is an omnibus survey that collects data from respondents in Great Britain. Information is gathered on a range of subjects, commissioned both internally by the Office for National Statistics (ONS) and by external clients (other government departments, charities, non-profit organisations and academia).

One individual respondent, aged 16 or over, is selected from each sampled private household to answer questions. Data are gathered on the respondent, their family, address, household, income and education, plus responses and opinions on a variety of subjects within commissioned modules. Each regular OPN survey consists of two elements. Core questions, covering demographic information, are asked together with non-core questions that vary depending on the module(s) fielded.

The OPN collects timely data for research and policy analysis evaluation on the social impacts of recent topics of national importance, such as the coronavirus (COVID-19) pandemic and the cost of living. The OPN has expanded to include questions on other topics of national importance, such as health and the cost of living.

For more information about the survey and its methodology, see the gov.uk OPN Quality and Methodology Information (QMI) webpage.

Changes over time

Up to March 2018, the OPN was conducted as a face-to-face survey. From April 2018 to November 2019, the OPN changed to a mixed-mode design (online first with telephone interviewing where necessary). Mixed-mode collection allows respondents to complete the survey more flexibly and provides a more cost-effective service for module customers.

In March 2020, the OPN was adapted to become a weekly survey used to collect data on the social impacts of the coronavirus (COVID-19) pandemic on the lives of people of Great Britain. These data are held under Secure Access conditions in SN 8635, ONS Opinions and Lifestyle Survey, 2019-2023: Secure Access. (See below for information on other Secure Access OPN modules.)

From August 2021, as coronavirus (COVID-19) restrictions were lifted across Great Britain, the OPN moved to fortnightly data collection, sampling around 5,000 households in each survey wave to ensure the survey remained sustainable.

Secure Access OPN modules

Besides SN 8635 (which includes the COVID-19 Module), other Secure Access OPN data includes sensitive modules run at various points from 1997-2019, including Census religion (SN 8078), cervical cancer screening (SN 8080), contact after separation (SN 8089), contraception (SN 8095), disability (SNs 8680 and 8096), general lifestyle (SN 8092), illness and activity (SN 8094), and non-resident parental contact (SN 8093). See the individual studies for further details and information on how to apply to use them.

There were over 4.7 million people aged between 30 and 34 in the United Kingdom in 2023, making it the most populous age group in that year. Those aged between 35 and 39 years comprised the next most numerous age group in 2023, at over 4.64 million people. Millennials overtake Boomers as biggest generation Post-war demographic trends, particularly the 'baby boom' phenomenon, have significantly influenced the current age distribution in the UK. The postwar peak of live births in 1947 resulted in the dominance of the Baby Boomer generation for several decades, until 2020 when Millennials became the largest generational cohort, surpassing the Boomers for the first time. The following year, the UK Boomer population was then overtaken by Generation X, the generation born between Boomers and Millennials. Generation Z, however, remains smaller than the three generations that preceded it, at 12.9 million individuals in 2022. Aging UK population poses challenges The median age of the UK population is projected to reach 44.5 years by 2050, compared to 34.9 years in 1950. This aging trend is indicative of broader global demographic shifts, with the median age of people worldwide forecasted to increase from 23.6 years in 1950 to 41.9 years by 2100. How countries like the UK manage their aging populations will be one of the key challenges of the next few decades. It is likely the UK's struggling National Health Service (NHS) will come under even more pressure in the coming years. There are also tough economic questions, in particular as more people enter retirement age and the UK's working population gets smaller in relation to it.

In 2022, the life expectancy at birth for women born in the UK was 82.57 years, compared with 78.57 years for men. By age 65 men had a life expectancy of 18.25 years, compared with 20.76 years for women.

Life expectancy in the United Kingdom was below 39 years in the year 1765, and over the course of the next two and a half centuries, it is expected to have increased by more than double, to 81.1 by the year 2020. Although life expectancy has generally increased throughout the UK's history, there were several times where the rate deviated from its previous trajectory. These changes were the result of smallpox epidemics in the late eighteenth and early nineteenth centuries, new sanitary and medical advancements throughout time (such as compulsory vaccination), and the First world War and Spanish Flu epidemic in the 1910s.

In 2022 life expectancy for both males and females at birth fell when compared to 2021. Male life expectancy fell from 78.71 years to 78.57 years, and from 82.68 years to 82.57 years for women.

For the year ending June 2024, approximately 1.2 million people migrated to the United Kingdom, while 479,000 people migrated from the UK, resulting in a net migration figure of 728,000. There have consistently been more people migrating to the United Kingdom than leaving it since 1993 when the net migration figure was negative 1,000. Although migration from the European Union has declined since the Brexit vote of 2016, migration from non-EU countries accelerated rapidly from 2021 onwards. In the year to June 2023, 968,000 people from non-EU countries migrated to the UK, compared with 129,000 from EU member states. Immigration and the next UK election Throughout 2023, immigration, along with the economy and healthcare, was consistently seen by UK voters as one of the top issues facing the country. Despite a pledge to deter irregular migration via small boats, and controversial plans to send asylum applicants to Rwanda while their claims are being processed, the current government is losing the trust of the public on this issue. As of February 2024, 20 percent of Britons thought the Labour Party would be the best party to handle immigration, compared with 16 percent who thought the Conservatives would handle it better. With the next UK election expected at some point in 2024, the Conservatives are battling to improve their public image on this and many other issues. Historical context of migration The first humans who arrived in the British Isles, were followed by acts of conquest and settlement from Romans, Anglo-Saxons, Danes, and Normans. In the early modern period, there were also significant waves of migration from people fleeing religious or political persecution, such as the French Huguenots. More recently, large numbers of people also left Britain. Between 1820 and 1957, for example, around 4.5 million people migrated from Britain to America. After World War Two, immigration from Britain's colonies and former colonies was encouraged to meet labor demands. A key group that migrated from the Caribbean between the late 1940s and early 1970s became known as the Windrush generation, named after one of the ships that brought the arrivals to Britain.

In 2011, 87.2 percent of the total population of the United Kingdom were white British. A positive net migration in recent years combined with the resultant international relationships following the wide-reaching former British Empire has contributed to an increasingly diverse population.

Varied ethnic backgrounds

Black British citizens, with African and/or African-Caribbean ancestry, are the largest ethnic minority population, at three percent of the total population. Indian Britons are one of the largest overseas communities of the Indian diaspora and make up 2.3 percent of the total UK population. Pakistani British citizens, who make up almost two percent of the UK population, have one of the highest levels of home ownership in Britain.

Racism in the United Kingdom

Though it has decreased in comparison to the previous century, the UK has seen an increase in racial prejudice during the first decade and a half of this century. Racism and discrimination continues to be part of daily life for Britain’s ethnic minorities, especially in terms of work, housing, and health issues. Moreover, the number of hate crimes motivated by race reported since 2012 has increased, and in 2017/18, there were 3,368 recorded offenses of racially or religiously aggravated assault with injury, almost a thousand more than in 2013/14.

There were 694,685 live births recorded in the United Kingdom in 2021, compared with 681,560 in the previous year. Between 1887 and 2021 the year with the highest number of live births was 1920 when there were approximately 1.13 million births, while the year with the fewest births was 1977, when there were just 657,038 births. Birth rate at a historic low in 2020 At 10.2 births per 1,000 people, the birth rate of the United Kingdom in 2020 was at a historic low. After witnessing a twenty-first century high of 12.9 in 2010, the birth rate gradually declined before a sharp decrease was recorded between 2012 and 2013. Although there was a slight uptick in the birth rate in 2021, when there were 10.4 births per 1,000 people, the total fertility rate reached a low of 1.53 births per woman in the same year. As well as falling birth and fertility rates, the average age of mothers has been increasing. In 1991, the average age of mothers at childbirth was 27.7 years, compared with 30.9 years in 2021. UK population reaches 67 million In 2022, the overall population of the United Kingdom was almost 67.6 million people. Of the four countries that comprise the UK, England has by far the highest population, at 57.1 million, compared with 5.45 million in Scotland, 3.13 million in Wales, and 1.91 million in Northern Ireland. These countries are far less densely populated than England, especially when compared to London, which had approximately 5,630 people per square kilometer, compared with just 70 in Scotland. After London, North West England was the second-most densely populated area of the UK, which includes the large metropolitan areas of the cities of Manchester, and Liverpool
