Why is "Saying all countries urbanise at the same rate" a common mistake in Global Urban Growth and Population Distribution?

Why it happens: Simplification. How to avoid it: Developed countries already ~80% urban; growth slow. Developing countries rapidly urbanising; Africa especially fast. Source: 0460 Examiner Reports 2022-2024

Global Urban Growth Study Notes — Cambridge IGCSE Geography 0460 (2024-2026 syllabus)

Urbanisation trends: 56% urban now, 68% by 2050. Megacities (>10M). Why urbanisation rates differ developed vs developing.

What you’ll learn

Mapped to the Cambridge IGCSE 0460 syllabus (2024-2026).

7.1.1 — Describe global urbanisation trends.
7.1.2 — Define megacity; identify examples.
7.1.3 — Explain why urbanisation rates differ.

Global urbanisation trends

Rapid + uneven.

Global trend. 56% urban (2022); projected 68% by 2050. Up from ~30% in 1950. Most urbanisation now in ASIA + AFRICA.

Pull factors.

JOBS (manufacturing, services, construction).
SERVICES (healthcare, education, water, electricity).
BETTER LIFE perceived.

Push factors.

AGRICULTURAL MECHANISATION reduces farm jobs.
DROUGHT, CONFLICT in rural areas.
Limited rural opportunities.

Cambridge tip. Mark scheme rewards trend + multiple reasons.

56% urban; 68% by 2050.
Pull: jobs + services.
Push: rural decline.

Megacities

10M population.

Megacity definition. City with population over 10 million.

Top megacities (2024).

Tokyo, Japan: ~37M.
Delhi, India: ~32M.
Shanghai, China: ~29M.
São Paulo, Brazil: ~22M.
Mumbai, India: ~20M.
Mexico City: ~22M.
Cairo: ~22M.

~33 megacities globally today.

Why growing. Rural-urban migration + natural population increase + globalisation concentrating economic activity.

Cambridge tip. Memorise definition + top examples.

Megacity = >10M.
Top: Tokyo, Delhi, Shanghai.
33 globally.

See the full worked example for global urban growth and population distribution →

Why urbanisation rates differ

Developed slow; developing fast.

Developed countries. Already ~80%+ urbanised. Some COUNTER-URBANISATION (back to rural). Aging populations mean fewer young workers migrating. Urban growth slow.

Developing countries. Rapid industrialisation + manufacturing. Limited rural opportunities. Young populations + high birth rates drive migration. African + Asian cities adding ~70M urban residents per year.

Africa especially fast. Lagos, Nairobi, Kinshasa, Dar es Salaam — among world's fastest-growing cities.

Cambridge tip. Match urbanisation rate to development level + demographics.

Developed: slow, some reverse migration.
Developing: rapid, especially Africa.
Young + growing populations drive it.

Step-by-step worked examples — Global Urban Growth and Population Distribution

Step-by-step solutions to past-paper-style questions on global urban growth and population distribution, written exactly the way a tutor would explain them at the board.

1Global urbanisation trends (6 marks)
Extended• Adapted from 0460/12 May/Jun 2024• urbanisation
Question
Describe global urbanisation trends. State THREE reasons people move to cities. (6 marks)
Step-by-step solution
1. Step 1
  Global trend (2 marks). ~56% of world's population in cities (2022); projected to ~68% by 2050. Sharp rise from ~30% in 1950. Most urbanisation now happening in Asia and Africa.
2. Step 2
  Reason 1 (1 mark). JOBS — cities have factories, services, construction work.
3. Step 3
  Reason 2 (2 marks). SERVICES — better healthcare, education, water supply, electricity available in cities.
4. Step 4
  Reason 3 (1 mark). Rural push factors — agricultural mechanisation reduces farm jobs; drought, conflict drive people from countryside.
Answer
56%+ urban, rising to 68%. Pull: jobs, services. Push: rural decline. Most urbanisation in Asia + Africa.
2Megacities (5 marks)
Extended• megacities
Question
Define a megacity. Identify THREE major megacities. State why they're growing. (5 marks)
Step-by-step solution
1. Step 1
  Megacity definition (1 mark). City with population OVER 10 million.
2. Step 2
  Three examples (3 marks). Tokyo (Japan, ~37 million — largest). Delhi (India, ~32M). Shanghai (China, ~29M). Other: Mumbai, Lagos, Cairo, São Paulo.
3. Step 3
  Why growing (1 mark). Rural-urban migration + natural population increase + globalisation concentrating economic activity.
Answer
Megacity = >10M people. Top examples: Tokyo, Delhi, Shanghai. Growing from migration + natural increase.
3Urbanisation patterns differ (5 marks)
Extended• urbanisation
Question
Explain why urbanisation in DEVELOPED countries is now slow but in DEVELOPING countries is rapid. (5 marks)
Step-by-step solution
1. Step 1
  Developed (2 marks). Already 80%+ urbanised. Some COUNTER-URBANISATION (people moving back to rural areas) for quality of life. Population aging — fewer young workers driving migration. Urban growth now slow.
2. Step 2
  Developing (3 marks). Rapid industrialisation + manufacturing. Rural areas have limited opportunities. Young populations + high birth rates drive migration. African and Asian cities adding ~70 million urban residents per year.
Answer
Developed: saturated urbanisation, some reverse migration. Developing: rapid growth from industrialisation + young populations.
