Public housing and the housing crisis
Edexcel IAL Geography · WGE02 Geographical Investigations
One response to housing shortages is for the state to build and manage housing itself. Its availability, quality and affordability vary greatly between cities (spec 2.4.3, key idea 1).
Origins of public housing
Public (social) housing is housing built, owned or subsidised by the state or not-for-profit bodies and let at below-market rents. It originated in the European industrial revolution, when rapid urban growth created overcrowded, insanitary slums; philanthropists and then city governments built model dwellings and later large council estates. In the 20th century public housing became a major part of the housing stock in many European cities and in some emerging-world cities.
Case study: Singapore
Singapore's Housing and Development Board (HDB) builds flats that most residents buy on long leases with state support. Singapore's Department of Statistics reports that in 2025, 77.2% of resident households lived in HDB dwellings, and 91.2% of resident households were owner-occupied. Public housing on this scale helped clear informal settlements and gives high-quality, affordable homes, but it requires a state that controls most land and plans tightly.

Variation between cities
Public housing provision differs in:
- Availability: in some cities it is a large share of homes; in others there are long waiting lists (the London Borough of Newham had about 34,000 households on its waiting list in 2022, Evening Standard).
- Quality: some estates are well maintained and popular; others suffered from poor design, high-rise blocks, crime and neglect, and have been demolished.
- Affordability: rents linked to incomes are affordable, but some 'affordable' housing is set as a percentage of market rent, which may still be out of reach.
Critics argue large estates can concentrate poverty; supporters argue public housing is the only way to house low-income key workers in expensive cities.
Worked example
Using Singapore's 2025 figures, estimate how many of every 1,000 resident households did not live in HDB dwellings.
- HDB share = 77.2%, so non-HDB share = 100 - 77.2 = 22.8%.
- 22.8% of 1,000 = 228.
Answer: About 228 households in every 1,000.
Check yourself
- What percentage of Singapore's resident households did not live in HDB dwellings in 2025? Give your answer to 1 decimal place.
Show answer
22.8 %. 100 - 77.2 = 22.8%.
- Public housing first developed in response to
- suburban sprawl in the 21st century
- overcrowded, insanitary housing during the European industrial revolution
- the building of eco-cities
- coastal flooding
Show answer
overcrowded, insanitary housing during the European industrial revolution. Industrial cities grew faster than decent housing.
- Why may 'affordable' housing set at 80% of market rent still be unaffordable in an expensive city?
- It is always free
- It is linked to incomes
- It is only for the rich
- Market rents are so high that 80% of them is still beyond low incomes
Show answer
Market rents are so high that 80% of them is still beyond low incomes. A discount on a very high rent can still be too high.
- Which is a common criticism of some large public housing estates built in the 20th century?
- Poor design and maintenance led to social problems
- They were too cheap to rent
- They had too few residents
- They were built on coasts
Show answer
Poor design and maintenance led to social problems. Some high-rise estates were demolished.
- What does Singapore's experience suggest about large-scale public housing?
- It always fails
- It only works in very poor countries
- It can house most of a population well when the state controls land and plans tightly
- It increases slum populations
Show answer
It can house most of a population well when the state controls land and plans tightly. 77.2% of households live in HDB flats.
- Explain why public housing can reduce a city's housing crisis.
Show answer
The state builds homes and lets or sells them below market price, increasing the supply of affordable housing so that low-income households are not priced out, made homeless or forced into overcrowded or informal housing.. Who provides, what is added, who benefits.
