This dataset provides Census 2021 estimates that classify usual residents in England and Wales by their country of birth, this dataset comprises a more detailed breakdown of birth country. The estimates are as at Census Day, 21 March 2021.

Census 2021 rounded migration estimates for local authorities in England and Wales were originally released on 28 June 2022 in rounded form. The bulletin explored change over time, regional variations and the composition of the population by sex and by five-year age group.

This update provides unrounded migration estimates from Country level down to Output Area.

Area type

Census 2021 statistics are published for a number of different geographies. These can be large, for example the whole of England, or small, for example an output area (OA), the lowest level of geography for which statistics are produced.

For higher levels of geography, more detailed statistics can be produced. When a lower level of geography is used, such as output areas (which have a minimum of 100 persons), the statistics produced have less detail. This is to protect the confidentiality of people and ensure that individuals or their characteristics cannot be identified.

Coverage

Census 2021 statistics are published for the whole of England and Wales. Data are also available in these geographic types:

• country - for example, Wales
• region - for example, London
• local authority - for example, Cornwall
• health area – for example, Clinical Commissioning Group
• statistical area - for example, MSOA or LSOA

Country of birth

The country in which a person was born.

For people not born in one of in the four parts of the UK, there was an option to select "elsewhere".

People who selected "elsewhere" were asked to write in the current name for their country of birth.

This dataset provides Census 2021 estimates that classify usual residents in England and Wales by country of birth and by age. The estimates are as at Census Day, 21 March 2021.

Estimates for single year of age between ages 90 and 100+ are less reliable than other ages. Estimation and adjustment at these ages was based on the age range 90+ rather than five-year age bands. Read more about this quality notice.

Focus on Wales paints a picture of the people of Wales. It includes information on their characteristics, sense of national identity, ethnic diversity and Welsh language skills, as well as looking at the Welsh-born living elsewhere in the United Kingdom.

In 2021 there were approximately 10.5 live births per 1,000 population in England, the second-lowest birth rate since 1971, when the crude birth rate was 15.9 births per 1,000 people.

Annual statistics on births and infant deaths based on babies born in a calendar year that died before their first birthday linked to their corresponding birth notification and their corresponding death registration.

According to the 2021 Census, 81.7% of the population of England and Wales was white, 9.3% Asian, 4.0% black, 2.9% mixed and 2.1% from other ethnic groups.

Among the nations of the United Kingdom, Northern Ireland had the highest number of live births per 1,000 in 2021, at 11.6, followed by England at 10.5, Wales at 9.3, and Scotland at 8.7. The crude birth rate has fallen for all nations of the UK when compared with 1971, while Northern Ireland has consistently had the highest number of live births per 1,000 people. Long-term birth trends After reaching a postwar peak of 18.8 births per 1,000 people, the UK's crude birth rate has declined considerably, falling to a low of just eleven births per 1,000 people in 2020. In that year, there were just 681,560 live births, compared with over one million in 1964. Additionally, the average age of mothers at childbirth in the UK has been steadily increasing since the mid-1970s. In 1975, for example, the average age at which mothers gave birth was 26.4 years, compared with 30.9 in 2021. Millennials overtake Boomers as the largest generation Due to the large number of births that happened in the years following the Second World War, the generation born during this time were called Baby Boomers, and until 2020 were the largest generation in the UK. Since that year, the Millennial generation, born between 1981 and 1996, has been the largest generational cohort. In 2023, there were almost 14.7 million Millennials, just over 14 million Generation X (born between 1965 and 1980), and around 13.6 million Baby Boomers. Generation Z, the generation immediately after Millennials, numbered approximately 13.2 million in this year.

The census is undertaken by the Office for National Statistics every 10 years and gives us a picture of all the people and households in England and Wales. The most recent census took place in March of 2021.The census asks every household questions about the people who live there and the type of home they live in. In doing so, it helps to build a detailed snapshot of society. Information from the census helps the government and local authorities to plan and fund local services, such as education, doctors' surgeries and roads.Key census statistics for Leicester are published on the open data platform to make information accessible to local services, voluntary and community groups, and residents. There is also a dashboard published showcasing various datasets from the census allowing users to view data for Leicester and compare this with national statistics.Further information about the census and full datasets can be found on the ONS website - https://www.ons.gov.uk/census/aboutcensus/censusproductsCountry of birthThis dataset provides Census 2021 estimates that classify usual residents in England and Wales by their country of birth.

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.

There were almost 695,000 live births recorded in the United Kingdom in 2021, compared with almost 682,000 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 approximately 657,000 births. Birth rate falls to 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 68 million In 2023, the overall population of the United Kingdom reached almost 68.3 million people. Of the four countries that comprise the UK, England has by far the highest population, at 57.7 million, compared with almost 5.5 million in Scotland, 3.2 million in Wales, and 1.9 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

Dataset population: Persons

Country of birth

Country of birth is the country in which a person was born. This topic records whether the person was born in or if they were not born in a country.

For the full country of birth classification in England and Wales, please see the National Statistics Country Classification.

Religion

This is a person's current religion, or if the person does not have a religion, 'No religion'. No determination is made about whether a person was a practicing member of a religion. Unlike other census questions where missing answers are imputed, this question was voluntary and where no answer was provided, the response is categorised as 'Not stated'.

Sex

The classification of a person as either male or female.

There were 11,480 deaths registered in England and Wales for the week ending November 14, 2025, compared with 11,297 in the previous week. During this time period, the two weeks with the highest number of weekly deaths were in April 2020, with the week ending April 17, 2020, having 22,351 deaths, and the following week 21,997 deaths, a direct result of the COVID-19 pandemic in the UK. Death and life expectancy As of 2022, the life expectancy for women in the UK was just over 82.5 years, and almost 78.6 years for men. Compared with 1765, when average life expectancy was under 39 years, this is a huge improvement in historical terms. Even in the more recent past, life expectancy was less than 47 years at the start of the 20th Century, and was under 70 as recently as the 1950s. Despite these significant developments in the long-term, improvements in life expectancy stalled between 2009/11 and 2015/17, and have even gone into decline since 2020. Between 2020 and 2022, for example, life expectancy at birth fell by 23 weeks for females, and 37 weeks for males. COVID-19 in the UK The first cases of COVID-19 in the United Kingdom were recorded on January 31, 2020, but it was not until a month later that cases began to rise exponentially. By March 5 of this year there were more than 100 cases, rising to 1,000 days later and passing 10,000 cumulative cases by March 26. At the height of the pandemic in late April and early May, there were around six thousand new cases being recorded daily. As of January 2023, there were more than 24.2 million confirmed cumulative cases of COVID-19 recorded in the United Kingdom, resulting in 202,156 deaths.

The UK censuses took place on 29th April 2001. They were run by the Northern Ireland Statistics & Research Agency (NISRA), General Register Office for Scotland (GROS), and the Office for National Statistics (ONS) for both England and Wales. The UK comprises the countries of England, Wales, Scotland and Northern Ireland.

Statistics from the UK censuses help paint a picture of the nation and how we live. They provide a detailed snapshot of the population and its characteristics, and underpin funding allocation to provide public services.

The aggregate statistics produced as outputs from UK censuses provide information on a wide range of demographic and socio-economic characteristics of the population of the United Kingdom. They are predominantly a collection of aggregated, or summary counts of the numbers of people, families or households resident in specific geographical areas or ‘zones’ possessing particular characteristics, or combinations of characteristics drawn from the themes of population, people and places, families, ethnicity and religion, health, work, and housing.

Aggregate statistics are available for the full range of geographies employed within the census, from the smallest (output areas with an average of 150 persons in England and Wales), to national level. For further information about the geographies used in the output of census aggregate statistics, see the section on census geography in the Office for National Statistics’ Beginner’s Guide to UK Geography.
