7.2 & 7.3 – Changing Towns and Cities

7.1 & 7.2 Changing Towns and Cities — Answers
Section A — Recall     Questions 1–5
1.

Define the term urbanisation.

[1]
Answer
Urbanisation is the process by which the proportion of people living in urban areas (towns and cities) increases over time.
2.

What is meant by natural increase in the context of urban growth?

[1]
Answer
Natural increase is when more people are born than die in an area, causing the population to grow.
3.

State the two main causes of rapid urban growth in Low Income Countries (LICs).

[2]
Answer
  • Rural–urban migration — large numbers of people moving from the countryside to cities
  • Natural increase — more births than deaths in the urban population

One mark for each cause clearly stated.

4.

What is the rural–urban fringe?

[1]
Answer
The rural–urban fringe is the zone at the edge of a city where urban (city) land uses and rural (countryside) land uses meet and mix together.
5.

Give three examples of opportunities that urban living provides.

[3]
Answer

Any three from the following (one mark each):

  • Culture — museums, theatres, festivals, diverse communities
  • Housing — wider variety of housing types available
  • Services — better hospitals, schools, universities, and public transport
  • Leisure — parks, sports facilities, cinemas, restaurants
  • Consumption — access to a wider range of goods and products
  • Economic development — more jobs, higher wages, greater opportunities to start businesses
Section B — Application     Questions 6–10
6.

Describe one social push factor and one social pull factor that cause rural–urban migration in LICs.

[4]
Answer

Social push factor (2 marks — 1 for identifying, 1 for describing):

Poor access to schools and healthcare in rural villages pushes people away. Rural communities often have few schools and limited medical facilities, meaning people cannot access a good education or healthcare for their families.

Social pull factor (2 marks — 1 for identifying, 1 for describing):

Cities offer better schools, universities, hospitals, and social services, which attract people. The prospect of a better education for their children and access to hospitals draws people towards urban areas.

Exam tip: For “describe” questions, do not just name the factor — always add a sentence that explains what it means or why it pushes/pulls people. That is where the second mark comes from.
7.

Explain why cities in High Income Countries (HICs) tend to have slower urban growth rates than cities in LICs.

[4]
Answer

Cities in HICs are already highly urbanised — most people already live in cities, so there is very little rural population left to move there. This means rural–urban migration is small.

Birth rates in HICs are also low, so natural increase in urban areas is slow. As a result, the urban population grows very little each year.

By contrast, LIC cities still have large rural populations moving to cities, and high birth rates lead to rapid natural increase once migrants settle. This combination produces much faster growth.

Exam tip: A strong “explain” answer names the factor, says what it means in the HIC context, and links it to the outcome (slow growth). Aim to make at least two separate linked points.
8.

Describe two challenges of rapid urban growth related to housing.

[4]
Answer

Challenge 1 (2 marks):

Rapid population growth leads to housing shortages and overcrowding. When the number of people arriving in a city grows faster than new homes can be built, there is not enough housing to go around. Many families are forced to share cramped spaces.

Challenge 2 (2 marks):

House prices and rents rise as demand for housing increases, making housing unaffordable for low-income residents. Many people cannot afford proper housing and are forced to live in poor-quality, overcrowded conditions.

9.

State what an unplanned settlement is. Give two challenges faced by people living in one.

[3]
Answer

Definition (1 mark):

An unplanned settlement is an area of housing built by residents on land they do not own and without permission from the government.

Two challenges (1 mark each — any two from below):

  • Housing is often built from temporary or unsafe materials, making it structurally dangerous
  • Little or no access to clean water, sewage systems, or electricity
  • Overcrowding and poor sanitation lead to the spread of disease
  • Residents have no legal ownership of the land and can be forcibly removed at any time
10.

Describe two ways in which urban sprawl affects the rural–urban fringe.

[4]
Answer

Any two of the following (2 marks each — 1 for naming the impact, 1 for explaining it):

  • Loss of farmland: Agricultural land is built over for housing estates and roads, permanently reducing the land available for food production.
  • Loss of green space and habitats: Natural areas such as fields and woodland are destroyed as the city expands, removing areas residents used for recreation.
  • Increased traffic: New residential areas on the fringe rely heavily on cars, leading to more congestion and air pollution on rural roads.
  • Pressure on local services: An influx of new residents increases demand for schools, doctors, and roads in areas that were not designed for large populations.
  • Changes to the character of rural settlements: Villages near the city edge lose their rural character as they are absorbed by the growing urban area, with house prices rising beyond the reach of local communities.
  • New economic activity: Out-of-town shopping centres, business parks, and industrial estates are built on the fringe where land is cheaper.
Section C — Challenge     Questions 11–15
11.

This question is about the causes of rapid urban growth in LICs.

(a) State one environmental push factor that causes people to leave the countryside and migrate to a city. [1]

(b) State one political pull factor that attracts people to move to a city in an LIC. [1]

(c) Explain why rapid urban growth in LICs is caused by both rural–urban migration and natural increase happening at the same time, rather than just one cause on its own. [4]

Answer
(a) Environmental push factor

Drought, flooding, or land degradation makes farming impossible or very difficult, forcing people to leave the countryside.

(b) Political pull factor

Governments often invest more in cities, making them safer and better-resourced than rural areas, which attracts people to move there.

(c) Why both causes together produce faster growth

Rural–urban migration brings large numbers of young adults into cities. These migrants settle and start families, raising the birth rate in the city. At the same time, cities offer better healthcare than rural areas, which reduces death rates. This means natural increase is high among the migrant population.

The two causes therefore reinforce each other: migration adds people directly, and those migrants then contribute to natural increase by having children. This combined effect produces faster growth than either cause could produce on its own.

Exam tip: The key to a high mark here is showing the link between the two causes — migration creates the conditions for high natural increase (young adults in cities). Just saying “both add people” is not enough.
12.

This question is about opportunities and challenges of rapid urban growth.

(a) Describe one opportunity that cities provide related to economic development. [1]

(b) Explain how inequality can develop in a rapidly growing city. [3]

(c) Explain how poor service provision and inequality are linked to each other in rapidly growing cities. [4]

Answer
(a) Economic development opportunity

Cities are centres of business and industry, offering more jobs, higher wages, and greater opportunities to start businesses and build wealth.

(b) How inequality develops

When cities grow very quickly, the economic benefits are not shared equally. Wealthier areas of the city receive investment and develop good services, while poorer areas are left with very little. Low-income residents — often recent migrants — are excluded from the economic gains of city growth. This creates a very wide gap between rich and poor, with high-quality housing and services in some areas existing alongside extreme poverty in others.

(c) Link between service provision and inequality

When a city grows faster than new services can be built, hospitals, schools, and water supplies become overwhelmed. Poorer areas of the city tend to receive fewer services than wealthier districts. This means that low-income residents have worse access to healthcare and education, making it much harder for them to improve their situation and escape poverty.

This creates a cycle that deepens inequality: the people who most need good services are the least likely to have access to them, while those in wealthier areas continue to benefit. Poor service provision and inequality therefore reinforce each other.

Exam tip: A strong answer describes the link in both directions — poor services worsen inequality, and inequality leads to unequal service distribution. Showing this feedback relationship is what earns the top marks.
13.

This question is about urban sprawl and the rural–urban fringe.

(a) Define the term urban sprawl. [1]

(b) Describe three impacts of urban sprawl on the rural–urban fringe and surrounding areas. [4]

(c) Explain why the loss of farmland due to urban sprawl is considered a particularly serious impact. [3]

Answer
(a) Definition of urban sprawl
Urban sprawl is the outward spread of a city into the surrounding countryside, as the city grows and new housing, roads, and businesses are built on the edge of the urban area.
(b) Three impacts on the rural–urban fringe

Any three of the following. Award up to 4 marks: approximately 1 mark for naming each impact and 1 additional mark for a well-described point.

  • Loss of farmland: Agricultural land is built over for housing estates and roads, permanently reducing the land available for food production.
  • Loss of green space and habitats: Natural areas such as fields and woodland are destroyed as the city expands, removing areas previously used for recreation.
  • Increased traffic and congestion: New residential areas on the fringe rely heavily on cars, leading to more congestion and air pollution on rural roads and in nearby villages.
  • Pressure on local services: An influx of new residents increases demand for schools, doctors, and roads in areas that were not designed for large urban populations.
  • Changes to the character of rural settlements: Villages near the city edge can lose their rural character as they become absorbed into the growing urban area, with house prices rising beyond the reach of local communities.
(c) Why loss of farmland is a particularly serious impact

Once agricultural land is built over with housing estates, roads, or retail areas, it is very difficult to restore. The infrastructure built on top of it is permanent, and the soil below is effectively destroyed. This means the land available for food production is permanently reduced — it cannot simply be recovered later if the city decides to shrink.

As cities continue to grow, this loss of farmland accumulates over time, making it a long-term concern for food supply and land use that is very hard to reverse.

14.

This question is about waste management in rapidly growing cities.

(a) Describe one challenge that rapidly growing cities face in managing waste. [2]

(b) Explain how unplanned settlements make waste management more difficult in rapidly growing cities. [3]

(c) Explain how poor waste management can affect the health of city residents. [3]

Answer
(a) Waste management challenge

Rapidly growing cities produce enormous amounts of rubbish that collection and disposal systems cannot keep up with. As the population grows faster than the infrastructure, large amounts of waste are left uncollected. This leads to the pollution of water, land, and air, creating serious problems for the city.

(b) How unplanned settlements worsen the problem

Unplanned settlements are built without organised planning or infrastructure, so they typically have no waste collection system at all. Large amounts of rubbish accumulate in these areas with no way to remove it. Because unplanned settlements are often very large and densely populated, they generate significant quantities of waste while being the most difficult areas for city authorities to reach and service. This means a substantial portion of the city’s total waste goes completely unmanaged, making the overall problem much harder to solve.

(c) Health effects of poor waste management

When waste is not collected and properly disposed of, it pollutes water sources, land, and air. This pollution causes serious health problems for residents. Poor sanitation in areas with no waste collection means that disease can spread quickly through the community.

People living in unplanned settlements are most seriously affected, as they often have no access to clean water or proper sewage systems. The combination of overcrowding and poor sanitation means that once disease begins to spread, it is very difficult to contain.

Exam tip: Link your points together — “waste is not collected” → “pollutes water” → “causes disease.” A chain of cause and effect is much stronger than just listing problems separately.
15.

“Cities in different parts of the world are growing at very different speeds.”

Explain why urban growth rates vary globally. Refer to at least three factors in your answer.

[8]
Answer

Urban growth rates vary because of differences in level of development, birth rates, and the scale of rural–urban migration. Economic activity is also a contributing factor.

Level of development: In High Income Countries (HICs), most people already live in cities. Because urbanisation is nearly complete, there is very little rural population left to move to urban areas. This means growth from migration is very slow. In Low Income Countries (LICs), large numbers of people still live in rural areas and have not yet made this move, so there is a much larger source of potential urban growth.

Rural–urban migration: In LICs, people are pushed away from the countryside by factors such as drought, land degradation, conflict, and poor access to services. They are pulled towards cities by the promise of jobs, higher wages, and better healthcare and education. This large-scale movement of people adds significantly to city populations each year. In HICs, rural living standards are already reasonable, so very few people are driven to leave.

Birth rate and natural increase: LIC cities have high birth rates because many migrants are young adults who have children after they arrive. Better healthcare in cities reduces death rates. The result is rapid natural increase. In HICs, birth rates are low, so natural increase is minimal and cities gain very little population through this means.

Economic activity: Rapid economic growth in LIC cities attracts further workers and investment, which draws even more people in and accelerates growth. HIC cities are well-established and grow more slowly because their economies are more mature.

In summary: urban growth rates vary because LICs are still going through the process of urbanisation — both migration and natural increase are driving fast growth. HICs have already completed this process, so their cities grow very slowly.
Exam tip: For an 8-mark extended answer, aim to make at least three clearly developed points. Each point should name the factor, explain what it means in the HIC or LIC context, and link it to the outcome (faster or slower growth). Simply listing factors without explanation will not earn full marks.
