Census 2021 – Housing stress in London

Housing stress describes a situation where the cost of housing is high relative to household income. The 2020-2021 English Housing Survey emphasised housing stress in London, with renters in the capital spending 35% of their household income on rent. With the current rise in the cost of living, this figure is now likely to be even higher.

The Office for National Statistics (ONS) has recently published small area data for the topic summary housing. Using a couple of datasets from this release, this blog looks at housing stress in London and how this has changed over the last 10 years. 

The proportion of owner occupied housing in London decreased between 2011 and 2021 – and at almost double the average decrease across England

Using the Census 2021 ‘Tenure’ dataset, we can measure the proportion of housing which is owner occupied. This means accommodation that is either owned outright, owned with a mortgage or loan, or shared ownership (paying part rent and part mortgage). As it has previously been well-documented that ownership levels have been driven down by rising house prices and the cost of living, this is an important measure to investigate when exploring current housing stress in London.

The table below lists the 10 Middle-Layer Super Output Areas (MSOAs) in London with the lowest proportion of owner occupied housing. Euston in Camden has the lowest percentage of households which are owner occupied (12.28%). MSOAs in Kensington & Chelsea make up 3 of the top 10, whilst Camden and Islington each contain 2 of the top 10. 

MSOA	Local Authority	% of owner occupied housing
Euston	Camden	12.28
Golborne & Swinbrook	Kensington & Chelsea	13.2
Somers Town	Camden	13.36
Walworth South	Southwark	13.41
Barnsbury West	Islington	14.48
Notting Dale	Kensington & Chelsea	14.55
Church Street	Westminster	14.69
Finsbury Park West	Islington	15.26
Ladbroke Grove	Kensington & Chelsea	15.63
Shadwell North	Tower Hamlets	16.73

We can also explore housing stress in London by looking at change in patterns in housing tenure between the 2011 and 2021 Census. As shown in the chart below, owner occupied housing in London has decreased by an average of 2.95 percentage points over these 10 years. This is almost double the decrease across England as a whole, which has shown an average percentage point difference of 1.88. This further widens the gap between London and the rest of England, with London now having an average of 46.63% houses which are owner occupied, compared to 64.51% across England.

We can also see that this decrease has been driven by a rise in privately rented housing, including accommodation that is rented from a private landlord or letting agency, employer of a household member, relative or friend of a household member. London has seen a percentage point increase of 5.14 for private rented accommodation, whilst this increase was slightly smaller across England (3.48).

Areas in East London have shown both the highest proportion of overcrowded households as well as the highest increase in overcrowding

Another measure of housing stress in London is levels of people living in overcrowded conditions. The Census 2021 ‘Occupancy rating for rooms’ dataset provides a measure of whether a household’s accommodation is overcrowded or under-occupied and gives an indication of how many households may be living in overcrowded conditions. Households are classified as overcrowded if there is at least one room fewer than needed for household requirements using standard definitions. Overcrowding can be stressful to health and well-being, often leading to adverse disease and mental health outcomes.

The table below lists the 10 local authorities in London with the highest proportion of overcrowded households. Newham has the highest proportion of overcrowding (25.33%), followed by Tower Hamlets (22.68%) and Brent (22.57%).

Local Authority	% of overcrowded households
Newham	25.33
Tower Hamlets	22.68
Brent	22.57
Camden	21.56
Westminster	20.86
Haringey	20.67
Barking and Dagenham	20.42
Hackney	19.52
Kensington and Chelsea	19.18
Hounslow	17.98

We have used Local Insight to hone in on Newham and further explore the spread of overcrowding across the wards in this local authority. The table below compares the proportion of overcrowding in all wards in Newham, showing that the wards with the highest levels are: Green Street East (33.80%), Plashet (33.16%) and Little Ilford (31.57%). These areas show significantly higher levels of overcrowding than the England average of 6.44%.

Area	Overcrowded (2021)	Number
England	6.44%	1,510,250
Beckton	21.59%	1,240
Boleyn	27.46%	1,251
Canning Town North	27.37%	1,682
Canning Town South	20.91%	572
Custom House	24.60%	1,526
East Ham	30.42%	1,298
East Ham South	27.22%	1,371
Forest Gate North	20.93%	768
Forest Gate South	26.57%	1,553
Green Street East	33.80%	1,500
Green Street West	30.87%	1,279
Little Ilford	31.57%	1,682
Manor Park	30.19%	1,506
Maryland	24.41%	1,125
Plaistow North	30.47%	1,752
Plaistow South	25.66%	1,083
Plaistow West & Canning Town East	27.49%	1,639
Plashet	33.16%	935
Royal Albert	24.40%	883
Royal Victoria	13.93%	1,009
Stratford	19.66%	1,370
Stratford Olympic Park	10.84%	503
Wall End	28.98%	1,328
West Ham	25.83%	1,379

The map below visualises the location of wards in Newham, with the wards showing the highest levels of overcrowding highlighted in blue. We can see that these wards are located in the North East of the borough.

Investigating the patterns in overcrowding between 2011 and 2021 also reveals an interesting story. Almost all local authorities in London have shown a decrease in household overcrowding over these 10 years, with an average decrease of 6.2 percentage points. However, two local authorities in the East of London (Havering and Barking and Dagenham) have shown slight increases in overcrowding, with percentage point differences of 0.5 and 0.3 respectively. 

We have used Local Insight to demonstrate this visually, taking Havering as an example. The maps below compare the spread of overcrowding across MSOAs in Havering in 2011 and in 2021, with darker red indicating higher levels of overcrowding. As we can see, the map on the right representing 2021 shows a larger amount of areas shaded red, indicating a higher proportion of overcrowded housing in a large amount of MSOAs. This is particularly prevalent for MSOAs in the centre of Havering, perhaps emphasising the easterly spread of overcrowding as these areas in suburban East London become more densely populated.
