The Rio de Janeiro case study in GCSE geography is an example of a city in a newly emerging economy (NEE) used to explain rapid urban growth, informal settlements called favelas, and the strategies used to improve them. Exam boards test it under "urban issues and challenges."
Why do exam boards use Rio de Janeiro as a case study?
AQA, Edexcel and other GCSE geography specifications require at least one detailed city case study for the human geography topic usually titled "urban issues and challenges" or similar. Boards typically ask for one example from a high-income country (HIC) and one from a low-income country (LIC) or newly emerging economy (NEE), so that students can compare how urban growth and its problems differ by level of development.
Rio de Janeiro is Brazil's second-largest city and one of the most commonly taught NEE examples because it shows, in one place, almost every issue this topic covers: rapid rural-to-urban migration, large informal settlements built on unsuitable land, extreme inequality between rich and poor districts, and a range of government-led improvement schemes that examiners can ask students to evaluate.
Why has Rio de Janeiro grown so quickly?
Rio's population expanded rapidly through the twentieth century as people moved from poorer, drought-affected rural regions of Brazil — particularly the north-east — in search of work, healthcare and education. Geographers call this combination of reasons pushing people from the countryside and pulling them toward cities rural-urban migration.
Two forces drove the growth:
- Push factors: limited farmland, drought, mechanisation reducing agricultural jobs, and poor access to services in rural Brazil.
- Pull factors: the perception of higher wages, more varied employment, and better healthcare and schools in a major coastal city.
Natural increase — more births than deaths among an already-young urban population — added further growth on top of migration. Because Rio's site is squeezed between steep granite hills and the Atlantic coast, there was never enough flat, formally planned land to absorb everyone who arrived.
What are favelas and why did they develop in Rio?
Favelas are informal, self-built settlements that grew up on land nobody else wanted — typically steep hillsides unsuitable for formal construction, or floodplains near rivers. Because migrants arrived faster than the city could build affordable formal housing, people built their own homes from whatever materials were available: brick, breeze block, corrugated metal and reused timber.
Favelas usually lack secure legal land title, and historically lacked reliable piped water, sewage systems and electricity. Rocinha, Rio's largest favela, is home to roughly 70,000 residents packed into a dense hillside community — a scale that makes clear why favelas are central to any Rio de Janeiro case study GCSE geography students are asked to write about.
Living on steep slopes brings specific hazards: heavy rainfall can trigger landslides, narrow unplanned streets make emergency access difficult, and poor drainage increases flood risk. These physical hazards, layered on top of social and economic disadvantage, are exactly why examiners expect students to discuss both the causes and consequences of informal settlement.
How has Rio tried to improve its favelas?
Rio de Janeiro's authorities have run several improvement schemes since the 1990s, each with a different approach to the same underlying squatter-settlement problem.
| Scheme | Approach | What it changed |
|---|---|---|
| Favela-Bairro | Government-funded infrastructure upgrading, started in the 1990s | Added paved roads, piped water, sanitation and street lighting without demolishing homes |
| Cable car links (e.g. Complexo do Alemão) | Transport investment connecting hillside communities to the metro | Cut journey times to the city centre and formal jobs |
| Self-help schemes | Small loans and building materials given directly to residents | Allowed households to gradually upgrade their own homes |
| Site-and-service / relocation schemes | Government-provided serviced plots or new housing for households on the most dangerous land | Moved residents away from landslide-prone slopes into safer, planned housing |
This mix of "upgrade in place" and "relocate the most at-risk households" is a pattern examiners expect students to recognise: top-level answers explain that no single scheme solves every problem, and each involves trade-offs between cost, speed and community disruption.
What other challenges does Rio face?
Beyond housing, Rio's rapid urban growth has created pressure on transport (severe traffic congestion on roads never designed for the current population), inequality (some of the widest gaps between rich and poor of any major city, visible in the contrast between wealthy coastal districts like Ipanema and nearby hillside favelas), and safety (parts of the city historically experienced high crime rates linked to poverty and limited state presence). Environmental pressures include deforestation on the hills surrounding the city and pollution of Guanabara Bay from untreated waste.
Frequently asked questions
What type of city is Rio de Janeiro for GCSE geography case study purposes?
Rio de Janeiro is classified as a city in a newly emerging economy (NEE), since Brazil has a rapidly industrialising economy that sits between low-income and high-income status. It is typically paired with a contrasting case study of a city in a high-income country, such as London or another UK city, so students can compare urban challenges across different levels of development.
What is the difference between a favela and a slum?
"Favela" is the specific Brazilian Portuguese term for an informal, self-built settlement, while "slum" is a more general English term used internationally for similar informal or run-down urban housing, such as barrios in other parts of Latin America or informal settlements in South Asian and African cities. The underlying features — informal construction, limited services, and insecure land tenure — are broadly similar across these terms, but exam answers should use the place-specific term for the case study named in the question.
Why do exam boards want a named case study rather than general knowledge?
Mark schemes for extended-writing questions reward specific, accurate detail — named schemes, real locations, and place-specific facts — because this demonstrates genuine study of a real place rather than generic assumptions. A vague answer that could apply to any city loses marks even if the general geography is correct, so learning named details from the Rio de Janeiro case study directly is essential exam technique.
Has Rio de Janeiro's population continued to grow in recent years?
Growth in Rio's core city area has slowed compared with the rapid expansion of the twentieth century, as Brazil's overall rate of urbanisation has levelled off and more people now leave crowded urban cores for surrounding suburbs. Favela populations remain substantial, however, and improvement schemes are an ongoing rather than completed process, which is why exam questions often ask students to evaluate how effective and how permanent these schemes really are.
