What this topic is asking
Topic 6.2 zooms out to the global pattern of urbanization. The College Board wants you to explain how the level (the share of people who live in cities) and the pace (how fast that share is rising) of urbanization vary across the world, especially the contrast between more developed and less developed countries, and to use the vocabulary of megacities and metacities. The skill is to read the global pattern and explain its causes and consequences.
Level and pace of urbanization
The first contrast is between how urbanized a region already is and how fast it is changing.
This pattern reverses the picture of a century ago, when the most urbanized places were the industrial cities of Europe and North America.
Why less developed countries urbanize fast
Rapid urbanization has clear causes.
This connects directly to the causes of migration (Topic 2.10): the same push-pull forces that move migrants between regions move them from countryside to city.
Megacities and metacities
Large cities are classified by population thresholds.
- A megacity is a city with more than 10 million people.
- A metacity (or hypercity) is a city with more than 20 million people.
Increasingly, the world's megacities and metacities are in the developing world (for example in South and East Asia), reflecting where urban growth is now concentrated. These differ from world cities (Topic 6.3), which are defined by global economic influence rather than population size alone.
Why this matters for the exam
Topic 6.2 sets the global frame for the unit: globalization and world cities (6.3), city size and distribution (6.4), and urban challenges (6.10, 6.11) all depend on understanding where and how fast urbanization is happening. FRQs ask you to describe the level contrast, explain the pace in less developed countries, or explain a challenge of rapid urbanization, so practice reading the global pattern and its drivers.
Try this
Q1. Identify the difference between a megacity and a metacity. [Recall]
- Cue. A megacity has more than 10 million people; a metacity has more than 20 million. The classification is by population threshold.
Q2. Explain why urbanization is currently faster in many less developed countries than in more developed ones. [Short explanation]
- Cue. Strong rural-to-urban migration (rural push, urban pull) plus high natural increase in young urban populations drives rapid growth, while more developed countries are already highly urbanized and grow slowly.
Exam-style practice questions
Practice questions written in the style of College Board exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
AP 2018 (style)1 marksA city with a population of more than 10 million people is most precisely classified as a: (A) primate city. (B) megacity. (C) world city. (D) metacity.Show worked answer →
A stimulus-style multiple choice item. The correct answer is (B).
A megacity is a city with a population greater than 10 million. A metacity (D) is even larger, with more than 20 million. A primate city (A) is the largest city in a country, far larger than the next, regardless of size; a world city (C) is a center of global economic command, defined by influence, not population alone.
The exam reward is matching the 10 million threshold to the term megacity.
AP 2020 (style)3 marksThe level and pace of urbanization differ around the world. (A) Describe the general difference in the level of urbanization between more developed and less developed countries. (B) Explain why urbanization is currently faster in many less developed countries. (C) Explain ONE challenge that rapid urbanization creates in less developed countries.Show worked answer →
A 3-point describe-explain FRQ.
(A) Describe (1 point): more developed countries are already highly urbanized, with a large share of population in cities, while less developed countries have lower but rapidly rising urban shares.
(B) Explain (1 point): less developed countries are urbanizing fast because of strong rural-to-urban migration, driven by rural push factors and the pull of urban jobs and services, combined with high natural increase in cities.
(C) Explain (1 point): rapid urbanization can outpace the supply of housing, jobs, and services, producing squatter settlements, informal economies, and pressure on water, sanitation, and transport.
Markers reward an accurate level contrast, a real cause of fast urbanization, and a genuine challenge it creates.
