Squatter settlements GCSE geography case studies focus on informal housing areas built illegally on unused or unsafe urban land, usually by low-income migrants who cannot afford formal housing. This guide explains why squatter settlements form, their typical characteristics, and the strategies cities use to improve them.
What is a squatter settlement?
A squatter settlement — also called an informal settlement, shanty town or slum — is an area of housing built without legal permission, planning approval or land ownership, usually on the edge of a city or on land considered unsuitable for building, such as steep slopes, riverbanks or land beside railway lines. Homes are typically self-built from scrap materials such as corrugated iron, wood, plastic sheeting and reused bricks.
Squatter settlements form mainly in Low Income Countries (LICs) and Newly Emerging Economies (NEEs), where rapid urbanisation and rural-to-urban migration outpace the ability of city governments to build enough affordable formal housing. Well-known examples studied at GCSE include Kibera in Nairobi, Kenya, and Dharavi in Mumbai, India — both large informal settlements that have grown alongside rapid city expansion.
Why do squatter settlements form?
Squatter settlements are a direct consequence of rapid, unplanned urban growth:
- Rural-to-urban migration — people move to cities in search of jobs, better healthcare and education, arriving faster than the city can house them.
- Lack of affordable housing — formal housing is too expensive or too slow to build for the number of new arrivals.
- Weak planning enforcement — city authorities in rapidly growing urban areas often lack the resources or legal power to prevent informal building.
- Available cheap or unclaimed land — undesirable or hazardous land near a city (steep hillsides, floodplains, land beside infrastructure) is often the only land migrants can access without payment.
What are the typical characteristics of a squatter settlement?
Although squatter settlements vary between cities, GCSE case studies usually highlight a shared set of features:
| Characteristic | Description |
|---|---|
| Housing | Self-built from scrap or low-cost materials; overcrowded; poor structural quality |
| Land tenure | No legal ownership or right to the land; constant risk of eviction |
| Sanitation | Limited or no piped water, sewerage or rubbish collection |
| Electricity | Informal or unreliable connections, often unsafe |
| Access | Narrow, unpaved streets that are hard for emergency vehicles to reach |
| Employment | Reliance on the informal economy — street trading, small workshops, recycling |
| Community | Strong social networks and self-organisation despite limited formal services |
These conditions create serious risks to health, safety and quality of life, but many squatter settlements also show remarkable resourcefulness, with residents building thriving local economies and tightly-knit communities from very limited resources.
How are squatter settlements improved?
City authorities and NGOs use several strategies to improve squatter settlements rather than simply demolishing them, since residents typically have nowhere else to go and clearance destroys existing jobs and social networks.
- Site and service schemes provide residents with a legal plot of land, basic infrastructure such as water pipes and electricity connections, and sometimes a foundation — residents then build or improve their own home over time.
- Self-help schemes give existing residents materials, small loans, and basic infrastructure improvements, allowing them to gradually upgrade their own housing while staying in their community.
- Slum upgrading improves an existing settlement in place — adding paved roads, drainage, sanitation and legal land rights — without relocating residents, as attempted in parts of Dharavi, Mumbai.
- Relocation and redevelopment clears an informal settlement and rehouses residents in new formal housing, though this approach is controversial because it can break up communities and disrupt local livelihoods.
Most modern approaches now favour improving settlements in place over clearance, because upgrading is cheaper, less disruptive, and keeps communities and their local economies intact.
What do examiners want you to include in a case study answer?
GCSE mark schemes reward answers that name a specific squatter settlement case study, describe at least one cause and one consequence of its growth, and evaluate a named improvement strategy with both its benefits and its limitations. Simply describing squatter settlements in general terms, without a named place and specific detail, will not reach the top mark band.
Frequently asked questions
What is a squatter settlement?
A squatter settlement is an area of informal, self-built housing constructed without legal permission or secure land rights, typically on the edge of a city or on land considered unsafe or undesirable for formal development. They form mainly in rapidly urbanising Low Income Countries and Newly Emerging Economies, where formal housing cannot keep pace with rural-to-urban migration.
Why do people choose to live in squatter settlements?
People often have little choice, since formal housing in the city is unaffordable or unavailable to new arrivals, and squatter settlements offer proximity to jobs, transport links and existing social networks that would be lost by living far from the city centre. Despite poor conditions, many residents build strong communities and informal economies that provide real, if precarious, opportunities.
What is the difference between a squatter settlement and a slum?
The terms overlap and are sometimes used interchangeably, but "squatter settlement" specifically highlights the illegal occupation of land without ownership rights, while "slum" more broadly describes any overcrowded urban area with poor housing and inadequate services, which can include both informal and formal but neglected housing. GCSE specifications generally treat squatter settlements as one major type of slum.
What is the best way to improve a squatter settlement?
There is no single "best" method — the right approach depends on the settlement's location, size and the resources available, which is exactly why examiners expect you to evaluate rather than simply describe. Slum upgrading and self-help schemes are generally considered more sustainable and less disruptive than clearance and relocation, because they keep communities and local economies intact while gradually improving housing and services.
