Dataset population: Persons, Households

Census 2021 rounded population and household estimates for local authorities and regions in England and Wales, by sex and five-year age group.

This dataset provides Census 2021 estimates that classify households with usual residents in England and Wales by various household characteristics, including variations in tenure by household size, household family composition, multi-generational households, and household level information on the age, ethnic group, religion, employment status and occupation of household members. The estimates are as at Census Day, 21 March 2021.

These datasets are part of Household characteristics by tenure, England and Wales: Census 2021, a release of results from the 2021 Census for England and Wales. Figures may differ slightly in future releases because of the impact of removing rounding and applying further statistical processes.

Total counts for some household groups may not match between published tables. This is to protect the confidentiality of households' data. Household counts have been rounded to the nearest 5 and any counts below 10 were suppressed; this is signified by a 'c' in the data tables.

This dataset uses middle layer super output area (MSOA) and lower layer super output area (LSOA) geography boundaries as of 2021 and local authority district geography boundaries as of 2022.

In this dataset, the number of households in an area is broken down by different variables and categories. If you were to sum the counts of households by each variable and category, it may not sum to the total of households in that area. This is because of rounding, suppression and that some tables only include data for certain household groups.

In this dataset, variables may have different categories for different geography levels. When variables are broken down by more categories, they may not sum to the total of the higher level categories due to rounding and suppression.

Social rent is not separated into “housing association, housing co-operative, charitable trust, registered social landlord” and “council or local authority districts” because of respondent error in identifying the type of landlord. This is particularly clear in results for areas which have no local authority districts housing stock, but there are households responding as having a “council or local authority districts” landlord type. Estimates are likely to be accurate when the social rent category is combined.

Household

A household is defined as one person living alone, or a group of people (not necessarily related) living at the same address who share cooking facilities and a living room, sitting room or dining area. This includes all sheltered accommodation units in an establishment (irrespective of whether there are other communal facilities) and all people living in caravans on any type of site that is their usual residence; this will include anyone who has no other usual residence elsewhere in the UK. A household must contain at least one person whose place of usual residence is at the address. A group of short-term residents living together is not classified as a household, and neither is a group of people at an address where only visitors are staying.

Usual resident

For Census 2021, a usual resident of the UK is anyone who, on Census Day, was in the UK and had stayed or intended to stay in the UK for a period of 12 months or more, or had a permanent UK address and was outside the UK and intended to be outside the UK for less than 12 months.

Household reference person (HRP)

A person who serves as a reference point, mainly based on economic activity and age, to characterize a whole household. The person is not necessarily the member of the household in whose name the accommodation is owned or rented.

Tenure

Whether a household owns or rents the accommodation that it occupies. Owner-occupied accommodation can be: owned outright, which is where the household owns all of the accommodation; owned with a mortgage or loan; or part owned on a shared ownership scheme. Rented accommodation can be private rented, for example, rented through a private landlord or letting agent; social rented through a local council or housing association; or lived in rent free, which is where the household does not own the accommodation and does not pay rent to live there, for example living in a relative or friend’s property or live-in carers or nannies. This information is not available for household spaces with no usual residents.

_Household size _

The number of usual residents in the household.

Household family composition

Households according to the relationships between members. Single-family households are classified by the number of dependent children and family type (married, civil partnership or cohabiting couple family, or lone parent family). Other households are classified by the number of people, the number of dependent children and whether the household consists only of students or only of people aged 66 years and over.

Multi-generational households

Households where people from across more than two generations of the same family live together. This includes households with grandparents and grandchildren whether or not the intervening generation also live in the household.

_Household combination of resident age _

Classifies households by the ages of household members on 21 March 2021. Households could be made up of residents aged 15 years and under; residents aged 16 to 64 years; residents aged 65 years and over; or a combination of these.

Ethnic group

The ethnic group that the person completing the census feels they belong to. This could be based on their culture, family background, identity or physical appearance. Respondents could choose one out of 19 tick-box response categories, including write-in response options. For more information, see ONS's Ethnic group, England and Wales: Census 2021 bulletin

Household combination of resident ethnic group

Classifies households by the ethnic groups household members identified with.

Religion

The religion people connect or identify with (their religious affiliation), whether or not they practice or have belief in it. This question was voluntary and includes people who identified with one of 8 tick-box response options, including 'No religion', alongside those who chose not to answer this question. For more information, see ONS's Religion, England and Wales: Census 2021 bulletin

Household combination of resident religion

Classifies households by the religious affiliation of household members who chose to answer the religion question. The classifications may include residents who did not answer the religion question.

Household combination of resident employment status

Classifies households by the employment status of household members aged 16 years and over between 15 and 21 March 2021. Households could be made up of employed residents (employee or self-employed); unemployed residents (looking for work and could start within two weeks, or waiting to start a job that had been offered and accepted); economically inactive residents (unemployed and had not looked for work between 22 February to 21 March 2021, or could not start work within two weeks); or a combination of these.

Occupation

"Classifies what people aged 16 years and over do as their main job. Their job title or details of activities they do in their job and any supervisory or management responsibilities form this classification. This information is used to code responses to an occupation using the Standard Occupational Classification (SOC) 2020. It classifies people who were in employment between 15 March and 21 March 2021, by the SOC code that represents their current occupation. The lowest level of detail available is the four-digit SOC code which includes all codes in three, two and one digit SOC code levels. Occupation classifications include :

• manager, director or senior official occupations (such as Elected Representatives and Senior Police Officers)
• professional occupations (such as Doctors and Teachers)
• associate professional and technical occupations (such as Police Officers and Counsellors)
• administrative or secretarial occupations (such as Office Managers and Receptionists)
• skilled trade occupations (such as Electricians and Chefs)
• caring, leisure or other service occupations (such as Teaching Assistants and Home Carers)
• sales and customer service occupations (such as Cashiers and Shopkeepers)
• process, plant and machine operatives (such as Bus Drivers and Scaffolders)
• elementary occupations (such as Postal Workers and Waiters)"

Some shorthand may be used in this workbook. Individual estimates suppressed with "[c]" relate to statistics based on a small number of respondents (< 10). Such values have been suppressed on quality grounds and to maintain confidentiality.

Armed forces personnel and defence employees are included in the census and recorded as usually resident using the standard definitions. The instructions given to personnel on how to respond to the census mean that this group cannot be reliably identified in census data on industry and occupation. Information on the size and characteristics of the UK armed forces population is produced by the Ministry of Defence (MOD).

This release provides insights into self-reported health in England and Wales in 2021, broken down by age and sex. Key findings are presented at country, regional and local authority level. Additional analyses compare general health to the 2011 Census and examines the relationship between deprivation and health at a national decile (England) or quintile (Wales) level can be found here.

In 2021 and 2011, people were asked “How is your health in general?”. The response options were:

• Very good
• Good
• Fair
• Bad
• Very bad

Age specific percentage

Age-specific percentages are estimates of disability prevalence in each age group, and are used to allow comparisons between specified age groups. Further information is in the glossary.

Age-standardised percentage

Age-standardised percentages are estimates of disability prevalence in the population, across all age groups. They allow for comparison between populations over time and across geographies, as they account for differences in the population size and age structure. Further information is in the glossary.

Details on usage of Age-standardised percentage can be found here

Count

The count is the number of usual residents by general health status from very good to very bad, sex, age group and geographic breakdown. To ensure that individuals cannot be identified in the data, counts and populations have been rounded to the nearest 5, and counts under 10 have not been included..

General health

A person's assessment of the general state of their health from very good to very bad. This assessment is not based on a person's health over any specified period of time.

Index of Multiple Deprivation and Welsh Index of Multiple Deprivation

National deciles and quintiles of area deprivation are created through ranking small geographical populations known as Lower layer Super Output Areas (LSOAs), based on their deprivation score from most to least deprived. They are then grouped into 10 (deciles) or 5 (quintiles) divisions based on the subsequent ranking. We have used the 2019 IMD and WIMD because this is the most up-to-date version at the time of publishing.

Population

The population is the number of usual residents of each sex, age group and geographic breakdown. To ensure that individuals cannot be identified in the data, counts and populations have been rounded to the nearest 5, and counts under 10 have not been included.

Usual resident

For Census 2021, a usual resident of the UK is anyone who, on census day, was in the UK and had stayed or intended to stay in the UK for a period of 12 months or more or had a permanent UK address and was outside the UK and intended to be outside the UK for less than 12 months.

These datasets are part of "What life looked like for different groups in England and Wales Census 2021", a release of results from the 2021 Census for England and Wales.

On 28 June 2022 ONS released the first results from the 2011 Census of England and Wales comprising for each local authority the estimated population at census day (21 March 2021) and the number of households. Population estimates are by five-year age band and sex. Estimates of responses rates for each local authority were also published. Read our blog post which describes how the census data relates to other population estimates and some of the pitfalls to avoid when interpreting the numbers.

This dataset is a March 2021 UK estimates for a range of census topics. Based on Census 2021 totals for England, Wales and Northern Ireland, added to estimated equivalent values derived from Scotland’s Census 2022. This is created by ONS Census Customer Services.

Methodology

Here is the Quality and methods guide for census-based statistics UK: 2021.

These data have been created to provide an image of how UK census data may have looked if the most recent UK censuses had been conducted with an aligned date of 21 March 2021. They provide census-based estimates of the usual resident population and of households in the UK, Great Britain, England, Wales, Northern Ireland, Scotland and England and Wales combined.

These data contain estimates for a range of topics, based on data from the three most recent UK censuses:

• Census of England and Wales, 21 March 2021; conducted by the Office for National Statistics
• Census of Northern Ireland, 21 March 2021; conducted by the Northern Ireland Statistics and Research Agency
• Census of Scotland, 20 March 2022; conducted by National Records of Scotland

Data for England, Wales and Northern Ireland are taken from Census 2021 results, while data for Scotland are based on interpolated Census 2011 and 2022 results and adjusted to ensure they are in line with mid-year estimates for Scotland. Census source data used to construct these tables have been taken from Census 2021 data for England, Wales and Northern Ireland, and Census 2011 and Census 2022 data for Scotland, all of which are publicly available.

Some of the data used in the construction of this publication are from previously published commissioned census datasets and custom datasets for Census 2021 and Census 2022, constructed using custom data tools on the ONS, NISRA and NRS websites.

It is important to emphasise that statistics presented in this publication for Scotland, Great Britain and the United Kingdom, although derived from census statistics, are not considered to be census statistics themselves, but rather census-based statistics. For Scotland, statistics from Census 2022 remain the definitive census statistics.

Accreditation status

All source data used to create this publication have been granted Accredited Official Statistics by the Office for Statistics Regulation (OSR).

This means they have been independently reviewed by OSR and found to comply with the standards of trustworthiness, quality and value as set out in the Code of Practice for Statistics. This means that they:

• meet identified user needs
• are well explained and easily accessible
• are produced based on appropriate data and methods
• are managed impartially and objectively in the public interest

This accreditation status is retained for the statistics in this dataset for England and Wales (separately and combined) and for Northern Ireland.

However, the statistics in this dataset for Scotland, Great Britain and the UK have just Official Statistics status, without accreditation.

The ONS have agreed this labelling with OSR, in recognition that methods required to create Scottish data for 2021, while pragmatic, necessarily involves greater uncertainty than had there been an actual data collection at that time.

According to the 2021 Census, 62.9% (37.5 million) of the overall population of England and Wales was of ‘working age’ (between 16 and 64 years old).

Census 2021 data on the highest qualification levels of the economically active population, by region and local authority. These tables also include a composite index score used to compare the qualification levels of the workforces in different areas, and the most similar local authorities in terms of qualification level profile.
