Back to table of contents2. Household size
There were 24,783,199 households with at least one usual resident in England and Wales on 21 March 2021. This was an increase of more than 1.4 million (6.1%) from 23,366,044 households in 2011.
There were 58,555,851 usual residents (98.3%) who lived in households. The remaining 1,041,691 usual residents (1.7%) lived in communal establishments. This is similar to 2011, when 98.2% lived in households and 1.8% in communal establishments. More detail on communal establishments will be published later, as part of the Housing topic summary.
Dividing the overall number of usual residents in households by the overall number of households gives the average household size. In 2021, this was 2.4 residents per household (2.4 residents per household in England and 2.3 residents per household in Wales). This is unchanged since 2011, when there were also 2.4 residents per household on average.
For the regions in England, the largest households on average were in London (2.5 residents per household) and the smallest households were in the North East (2.2 residents per household).
The local authorities in England with the highest average household size were Newham, Slough and Redbridge (all 3.0 residents per household). In Wales, they were Cardiff and Newport (both 2.4 residents per household).
The local authorities in England with the lowest average household size were the City of London (1.7 residents per household) and North Norfolk (2.1 residents per household). In Wales, it was Conwy (2.2 residents per household).
The distribution of household size within an area provides an even more detailed understanding, beyond average household size.

Back to table of contents3. Household deprivation
Households in England and Wales were also classified in terms of dimensions of deprivation, based on selected household characteristics. Specifically, households were considered to be deprived if they met one or more of the following four dimensions of deprivation:
- employment: where any member of a household, who is not a full-time student, is either unemployed or economically inactive due to long-term sickness or disability.
- education: no person in the household has at least five or more GCSE passes (grade A* to C or grade 4 and above) or equivalent qualifications, and no person aged 16 to 18 years is a full-time student
- health and disability: any person in the household has general health that is “bad” or “very bad” or is identified as disabled
- housing: the household’s accommodation is either overcrowded, with an occupancy rating of negative 1 or less (implying that it has one fewer room or bedroom required for the number of occupants), or is in a shared dwelling, or has no central heating
Overall, 51.7% of households in England and Wales in 2021 (12.8 million) were deprived in at least one of these dimensions (51.6% of households in England and 54.1% of households in Wales). The number of households deprived in at least one dimension has decreased since 2011, when it was 13.5 million (57.6%).
In 2021, 33.5% (8.3 million) households in England and Wales were deprived in one dimension, 14.3% (3.5 million) were deprived in two dimensions, 3.7% (929,000) were deprived in three dimensions and 0.2% (57,000) were deprived in all four dimensions. The remaining 48.3% (12.0 million) were not deprived in any dimension.
The North East was the region of England in which the highest proportion of households were deprived in at least one dimension (54.6%, 641,000). By contrast, the region with the highest proportion of households that were not deprived in any dimension was the South East (52%, 2.0 million).
The local authorities with the highest proportion of households deprived in at least one dimension included Barking and Dagenham (62.4%) and Sandwell (62.1%) in England, and Blaenau Gwent (61.7%) and Merthyr Tydfil (59.8%) in Wales. Those with the highest proportion of households deprived in all four dimensions included Camden and Westminster (both 0.7%) in England, and Cardiff, Newport and Merthyr Tydfil (all 0.3%) in Wales.
In contrast, the English local authorities with the highest proportion of households that were not deprived in any dimension included Elmbridge (61.9%), Wokingham (61.5%) and Richmond upon Thames (61.0%). In Wales, the local authorities with the highest proportion of households not deprived in any dimension were Monmouthshire (51.7%) and the Vale of Glamorgan (51.0%).

Household deprivation is a complex topic, and the data here simply show how many households were deprived in any of the four stated dimensions available from the census. This repeats an equivalent release from the 2011 Census. Detailed information on the stated dimensions will be published in upcoming topic releases and with the release of multivariate data.
Back to table of contents4. Household composition
Responses to the census are used to calculate household composition, which refers to the relationship between household members. For example, a household might consist of a family, of unrelated adults living together, or it might just be one person living alone.
Across England and Wales, the data show that 63.0% of households (15.6 million) were single family households, 30.2% (7.5 million) were one person households and 6.8% (1.7 million) were other household types, including households where multiple families lived together and households where unrelated adults lived together. This is similar to 2011, when 62.6% were single family households, 30.2% were one person households and 7.1% were other household types.
The most common types of single family household included those with a married or civil partnership couple with dependent children (3.5 million, 14.3% of all households) and those with a married or civil partnership couple with no children (2.6 million, 10.4%). The greatest increase was for single family households with a cohabiting couple with non-dependent children, a household type that increased by 56.1% across the past decade, from 115,000 (0.5%) in 2011 to 180,000 (0.7%) in 2021.
There were 3.2 million one person households with residents aged 66 years or over (12.9% of all households). The remaining 4.3 million (17.3%) one person households in 2021 were for younger people.
Finally, for other household types, there were 656,000 households (2.6%) in which multiple families lived together with dependent children, a proportion that has remained the same since 2011, when there were 602,000 such households (2.6%). There were 1.0 million (4.2%) other types of household in 2021, for example, full-time students.

Back to table of contents5. Legal partnership status
Same-sex marriage was legalised in 2014 and opposite-sex civil partnerships were legalised in 2019. The questions on marriage and civil partnerships were updated for 2021 to reflect this.
The results for 2021 show that, as in 2011, the largest group was those people who reported that they were married or in a civil partnership, at 21.7 million (44.6% of all usual residents aged 16 years and over). While the number of people in marriage or civil partnerships has risen by about 380,000 since 2011 (from 21.3 million), this was a decrease as a proportion of all usual residents aged 16 years and over (from 46.8%).
Of the 21.6 million people who were married (44.4% of all usual residents aged 16 years and over), 0.6% of individuals (134,000) were in same-sex couples, compared with 99.4% (21.4 million) in opposite-sex couples. A total of 103,000 people (0.2%) reported that they were in civil partnerships, of whom 65% (67,000) were in same-sex couples, compared with 35% (36,000) in opposite-sex couples.
The percentage of people who had never married and never registered a civil partnership increased by 3.3 percentage points from 34.6% (15.7 million) in 2011 to 37.9% (18.4 million) in 2021. The number of people who were divorced or whose civil partnership had been dissolved also rose, from 4.1 million (9.0%) in 2011 to 4.4 million (9.1%) in 2021.
Finally, there were declines in the proportion of people who were widowed or the surviving partner of a civil partnership, from 3.2 million (7.0%) in 2011 to 3.0 million (6.1%) in 2021, and in those who were separated but still legally married or in a civil partnership, from 1.2 million (2.6%) in 2011 to 1.1 million (2.2%) in 2021.

8. Glossary
Dependent child
A dependent child is a person aged 0 to 15 years in a household or a person aged 16 to 18 years who is in full-time education and lives in a family with their parent, parents, grandparent or grandparents. It does not include any person aged 16 to 18 years who has a spouse, partner or child living in the household.
Family
A family is a group of people who are either:
- married, civil partnered or cohabiting couple with or without children (the children do not need to belong to both members of the couple)
- a lone parent with children
- a married, civil partnered or cohabiting couple with grandchildren but where the parents of those grandchildren are not present
- a single or couple grandparent with grandchildren but where the parents of those grandchildren are not present
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 share a living room or sitting room, or dining area
This includes:
- sheltered accommodation units in an establishment where 50% or more have their own kitchens (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.
Household composition
Households according to the relationships between members.
One-family households are classified by:
- the number of dependent children
- 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
- whether the household consists only of students or only of people aged 66 years and over
Legal partnership status
Classifies a person according to their legal marital or registered civil partnership status on Census Day, 21 March 2021.
It is the same as the 2011 Census variable “Marital status” but has been updated for Census 2021 to reflect the revised Civil Partnership Act that came into force in 2019.
In Census 2021 results, “single” refers only to someone who has never been married or in a registered civil partnership.
Usual resident
A usual resident is anyone who on Census Day, 21 March 2021 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.
Back to table of contents9. Measuring the data
Reference date
The census provides estimates of the characteristics of all people and households in England and Wales on Census Day, 21 March 2021. It is carried out every 10 years and gives us the most accurate estimate of all the people and households in England and Wales.
We are responsible for carrying out the census in England and Wales, but will also release outputs for the UK in partnership with the Welsh Government, the National Records of Scotland (NRS) and the Northern Ireland Statistics and Research Agency (NISRA). The census in Northern Ireland was also conducted on 21 March 2021, whereas Scotland’s census was moved to 20 March 2022. All UK census offices are working closely together to understand how this difference in reference dates will impact UK-wide population and housing statistics, in terms of both timing and scope.
Response rate
The person response rate is the number of usual residents for whom individual details were provided on a returned questionnaire, divided by the estimated usual resident population.
The person response rate for Census 2021 was 97% of the usual resident population of England and Wales, and over 88% in all local authorities. Most returns (89%) were received online. The response rate exceeded our target of 94% overall and 80% in all local authorities.
Further information on question-specific response rates will be published in a separate report later this year.
