In the 2011 UK Census, the total population of the United Kingdom was about 63,182,000. It is the 21st most populated country in the world. Its population density is 259 people per square kilometre (671 people per square mile), with England having significantly greater density than Wales, Scotland, and Northern Ireland. Almost a third of the population lives in England's southeast, which is predominantly urban and suburban, with about 9,000,000 in the capital city, London, whose population density is just over 5,200 per square kilometre (13,468 per sq mi).
The population of the United Kingdom has undergone demographic transition—that is, the transition from a (typically) pre-industrial population, with high birth and mortality rates and slow population growth, through a stage of falling mortality and faster rates of population growth, to a stage of low birth and mortality rates with, again, lower rates of growth. This growth through 'natural change' has been accompanied in the past two decades by growth through net migration into the United Kingdom, which since 1999 has exceeded natural change. By 2031, the United Kingdom is expected to have a total population of 67.1 million, with the majority of the population growth coming from net migration.
The United Kingdom's high literacy rate (99% at age 15 and above) is attributable to universal public education, introduced at the primary level in 1870 (Scotland 1872, free 1890) and at the secondary level in 1900. Parents are obliged to have their children educated from the ages of 5 to 16 years (18 in England as of 2013), and can continue education free of charge in the form of A-Levels, vocational training, and apprenticeship until the age of 18. The Church of England and the Church of Scotland are the national churches in their respective countries (Wales has had no established church since disestablishment (1920)), and all the major religions found in the world are represented in the United Kingdom.
The United Kingdom's population is predominantly White British. Lying near continental Europe, the countries that formed the United Kingdom were subject to many invasions and migrations from the continent, especially from Scandinavia, and including Roman occupation for several centuries. Historically, British people were therefore thought to be descended mainly from the different ethnic stocks that settled there before the 11th century: pre-Celtic, Celtic, Anglo-Saxon, Viking, and Norman. Modern genetic testing has revealed the complexity of the British gene pool; some studies in the early 21st century suggested that as much as 80% of white British DNA may come from paleolithic people who settled in the British Isles 12,000 years ago.
Celtic languages are spoken in Scotland, Cornwall, and Northern Ireland; the predominant language overall is English. Welsh is widely spoken as the first language in North and West Wales, and less so in the South East of the country, where English is the dominant first language.

Roman Britain had an estimated population between 2.8 million and 3 million at the end of the second century CE. At the end of the fourth century, it had an estimated population of 3.6 million, of whom 125,000 consisted of the Roman army and their families and dependents. The urban population of Roman Britain was about 240,000 people at the end of the fourth century. Roman Britain's capital city, Londinium, is estimated to have had a population of about 60,000. Londinium was a diverse city, with inhabitants from across the Roman Empire, including natives of Britannia and Romans who were raised in continental Europe, the Middle East, and North Africa. There was also cultural diversity in other Roman-British towns, which were sustained by considerable colonial migration, both within Britannia and from other Roman territories, including North Africa, Roman Syria, the Eastern Mediterranean, and continental Europe.
During the Industrial Revolution, child mortality decreased dramatically. The proportion of children born in London who died before the age of five decreased from 74.5 per thousand in 1730–1749 to 31.8 per thousand in 1810–1829. According to Robert Hughes in The Fatal Shore, the population of England and Wales, which had remained steady at 6 million from 1700 to 1740, rose dramatically after 1740.
The Great Irish Famine, which began in the 1840s, caused the deaths of one million Irish people, and caused well over a million to emigrate. Mass emigration became entrenched as a result of the famine, and the population continued to decline until the mid-20th century.
|Percentage of total
(The population of Great Britain is therefore 64,553,909 (97.2% of UK) in an area of 228,956 km2 (94.3% of UK) and the population density is 282/km2.)
The United Kingdom (UK) Office for National Statistics' 2016-based National Population Projections indicated that, if recent trends continue, the UK's population would increase by 3.6 million between mid-2016 and mid-2026. This represents an average annual growth rate of 0.5%. Over the same period, the population of England is projected to grow by 5.9%; for Wales, this figure is 3.1%, while for Scotland and Northern Ireland the figures are 3.2% and 4.2% respectively. These projections do not allow for any possible effects of the UK leaving the European Union.
There are 13 urban areas that exceed 500,000 inhabitants: they are centred on London, Birmingham, Glasgow, Leeds and Bradford, Southampton and Portsmouth, Sheffield, Liverpool, Leicester, Manchester, Belfast, Bristol, Newcastle upon Tyne and Nottingham.
The population of the UK in the 2011 census was 63 million, of whom 31 million were male and 32 million female. The 2011 census recorded the population of England as 53.0 million, Scotland as 5.3 million, Wales as 3.1 million, and Northern Ireland as 1.8 million.
Population change over time
The following table shows the total UK population estimated at census dates. Pre 1901 figures include the whole of Ireland, whereas from 1901 onwards only the population of Northern Ireland is included.

In 2015, there were 777,165 recorded live births in the UK. The crude birth rate was 11.9 per 1,000 population. The total fertility rate was 1.80. Also in 2015, 602,782 deaths were recorded, with the crude death rate being 9.3 per 1,000. The infant mortality rate was 3.9 per 1,000 live births. Population density based on:
- Post-1901: calculated 243,820 km² area of the United Kingdom based on its current boundaries.
- Pre-1901: As above plus calculated 70,273 km² area of the Republic of Ireland.

The key features of the age distribution profile for the UK population, as measured in the 2011 Census, were summarised in December 2012 by the Office for National Statistics in terms of peaks and wide bands of the pyramid reflecting high numbers of births in previous years, particularly for people aged 60–64 born following the Second World War and those aged 40–49, born during the 1960s baby boom. There is a smaller number of children aged five to nine years than ten years ago, which is a consequence of low numbers of births at the beginning of the 21st century, and the broadening of the pyramid in the 0–4 years category is due to higher numbers of births in recent years. At higher ages, females outnumber males, reflecting the higher life expectancy of females. At lower ages, there are more males than females, reflecting that there are slightly more boys than girls born each year.
The most recent UK Office for National Statistics' population estimates for mid-2016 suggest the median age of the UK population was 40.0 years.
In 2015, there were estimated to be over half a million people (556,270) aged 90 and over living in the UK, up from 194,670 people in 1985, and there were estimated to be 14,570 centenarians (people aged 100 or over) and 850 people aged 105 or over.
The UK Office for National Statistics' 2016-based National Population Projections suggest that the UK population will continue to age, with the number of people aged 85 and over doubling from 1.6 million in mid-2016 to 3.2 million in mid-2041.

In 2012, the UK's total fertility rate (TFR) was 1.92 children per woman, below the replacement rate, which in the UK is 2.075. In 2001, the TFR was at a record low of 1.63, but it then increased every year until it reached a peak of 1.96 in 2008, before decreasing again. The TFR was considerably higher during the 1960s 'baby boom', peaking at 2.95 children per woman in 1964. In 2012 and 2013, England and Wales's TFR decreased to 1.85. In Scotland however TFR is lower: it decreased from 1.75 in 2010 to 1.67 in 2012. Northern Ireland has the highest TFR in the UK, standing at 2.02 in 2010 and 2.03 in 2012.
In 2014, 27% of births were to mothers born outside the UK, a 0.5 point increase since 2013. The 2014 fertility rate was higher for foreign-born mothers (2.09) than UK-born mothers (1.76). In the 2010–14 time period, the most common countries of birth for mothers (excluding the UK) were Poland, Pakistan and India; and Poland and India for fathers. Within the UK, Newham, London had the highest rate of births to non-UK mothers (76.7%) and Torfaen, Wales the lowest (3.2%).
Below is the number of births in England and Wales in 2011 by mother's country of birth, as well as their total fertility rate.

There are known difficulties in producing reliable estimates of the lesbian, gay, bisexual and transgender population.
The Integrated Household Survey, published by the Office for National Statistics, provides the following estimates for the adult UK population as of 2011:
- 1.1 percent (approximately 545,000 adults at the time of the survey) identify as gay or lesbian.
- 0.4 percent (approximately 220,000 adults) identify as bisexual.
- 0.3 percent identify as "other".
- 3.6 percent of those surveyed replied "don't know" or refused to answer the question.
- 0.6 percent of those surveyed provided "no response" to the question.
- An estimated 2.7 percent of 16- to 24-year-olds in the UK identify as gay, lesbian or bisexual compared with 0.4 percent of those aged over 65.
Other sources provide alternative estimates of the population by sexual orientation. For example, one British journal published in 2004 estimated that approximately 5% of the British population is gay. A government figure estimated in 2005 that there are 3.6 million gay people in Britain comprising 6 percent of the population., though a report by the Equality and Human Rights Commission described that estimate as 'of questionable validity' when set against available survey estimates.
The Gender Identity Research and Education Society (GIRES) estimated in 2009 that "56,000 might potentially be transsexual people", noting that it is very difficult to make a reliable estimate. This would be 0.09% of the population at the time.
Country of birth
Below are the 60 largest foreign-born groups in the UK according to 2019 ONS estimates.

|White: Irish Traveller||63,193||0.10%|
|Asian or Asian British: Total||2,578,826||4.39%||4,373,339||6.92%|
|Asian or Asian British: Indian||1,053,411||1.79%||1,451,862||2.30%|

|Asian or Asian British: Bangladeshi||283,063||0.48%||451,529||0.71%|
|Asian or Asian British: Chinese[note 1]||247,403||0.42%||433,150||0.69%|
|Asian or Asian British: Asian Other||247,664||0.42%||861,815||1.36%|
|Black or Black British[note 2]||1,148,738||1.95%||1,904,684||3.01%|
- In 2001, listed under the "Other ethnic group" heading.
- For the purpose of harmonising results to make them comparable across the UK, the ONS includes individuals in Scotland who classified themselves in the "African" category (29,638 people), which in the Scottish version of the census is separate from "Caribbean or Black" (6,540 people), in this "Black or Black British" category. The ONS note that "the African categories used in Scotland could potentially capture White/Asian/Other African in addition to Black identities".
The traditional religion in the United Kingdom is Christianity. In England the established church is the Church of England (Anglican). In Scotland, the Church of Scotland (a Presbyterian Church) is regarded as the 'national church' but there is not an established church.
In Wales there is no established church, with the Church in Wales having been disestablished in 1920. Likewise, in Ireland, the Church of Ireland was disestablished in 1871. In Northern Ireland and similarly in parts of Scotland, there is a degree of sectarian divide between Roman Catholic and Protestant communities.
The table below shows data regarding religion for the 2001 and 2011 censuses:
|Religion not stated||4,528,323||7.17%|
|(No religion and Religion not stated)||13,626,299||23.18%||20,749,832||32.84%|
In the 2011 Census, rather than select one of the specified religions offered on the Census form, many people chose to write in their own religion. Some of these religions were reassigned to one of the main religions offered. In England and Wales, 241,000 people belonged to religious groups which did not fall into any of the main religions. The largest of these were Pagans (57,000) and Spiritualists (39,000). The census also recorded 177,000 people stating their religion as Jedi Knight. These returns were classified as "No religion", along with Atheist, Agnostic, Heathen and those who ticked "Other" but did not write in any religion.
In 2012 the British Social Attitudes Survey found the highest number to be non-religious (48%) followed by Christians (46%) with another six percent identifying otherwise. Discrepancies found between surveys may be the result of differences in phrasing, question order, and data collection method.
The United Kingdom's de facto official language is English which is spoken as a first language by 95% of the population. Six regional languages; Scots, Ulster-Scots, Welsh, Cornish, Irish and Scottish Gaelic are protected under the European Charter for Regional or Minority Languages. Abilities in these languages (other than Cornish) for those aged three and above were recorded in the UK census 2011 as follows.

Each country of the United Kingdom has a separate education system, with power over education matters in Scotland, Wales and Northern Ireland being devolved.
The Secretary of State for Education is responsible to the UK Parliament for education in England. Depending on the status of state schools, control of day-to-day administration and funding may be the responsibility of either the local education authorities or the school's own governing institution. Universal state education in England and Wales was introduced for primary level in 1870 and secondary level in 1900. Education is mandatory from ages 5 to 18, raised from 16 (15 if born in late July or August) in 2013. The majority of children are educated in state-sector schools, only a small proportion of which select on the grounds of academic ability. Despite a fall in actual numbers, the proportion of children in England attending private schools rose slightly from 7.1% to 7.3% between 2004 and 2007.
Just over half of students at the leading universities of Cambridge and Oxford had attended state schools. State schools that are allowed to select pupils according to intelligence and academic ability can achieve comparable results to the most selective private schools: out of the top ten performing schools in terms of GCSE results in 2006, two were state-run grammar schools. England has four universities ranked amongst the top ten in the 2011 THES - QS World University Rankings.
In Scotland, the Cabinet Secretary for Education and Lifelong Learning is responsible to the Scottish Parliament for education, with day-to-day administration and funding of state schools being the responsibility of local authorities. Scotland first legislated for universal provision of education in 1696. The proportion of children in Scotland attending private schools is just over 4%, though it has been rising slowly in recent years. Scottish students who attend Scottish universities pay neither tuition fees nor graduate endowment charges, as the fees were abolished in 2001 and the graduate endowment scheme was abolished in 2008.
The Welsh Government Minister for Education is responsible to the Senedd for education in Wales. One of the most notable distinctive features of education in Wales is the emphasis on the Welsh language – lessons in which are compulsory for all until the age of 16. Whilst a significant minority of students (15.7% in the 2014\15 academic year) are taught primarily through the medium of Welsh.
The Northern Ireland Assembly is responsible for education in Northern Ireland though responsibility at a local level is administered by 5 Education and Library Boards covering different geographical areas.
The Programme for International Student Assessment coordinated by the OECD currently ranks the overall knowledge and skills of British 15-year-olds as 13th in the world in reading literacy, mathematics, and science with the average British student scoring 503.7, compared with the OECD average of 493.
