Unit 7: Industrial and Economic Development Patterns and Processes

Unit 7 covers industrialization, economic sectors, measures of development, and theories that explain global inequality. Rostow's stages, Wallerstein's world-systems theory, and dependency theory are compared as competing explanations. Trade, globalization, and sustainable development close both the unit and the course.

What is covered

Topics inside this unit.

These topics describe the scope students most often review for this part of AP Human Geography. Treat them as a study checklist rather than an exhaustive list of what a single exam form can sample.

Industrialization and its diffusion: The Industrial Revolution's origins and spread, and the location factors that concentrated industry in particular places.
Economic sectors and Weber's model: Primary through quinary sectors, and least-cost theory weighing transportation, labor, and agglomeration.
Measures of development: Gross domestic and national product, gross national income per capita, the Human Development Index, and gender-related indices.
Women and economic development: Gender gaps in income, education, and formal employment, and microfinance and other interventions aimed at them.
Theories of development: Rostow's stages of growth, Wallerstein's core-periphery world-systems theory, and dependency theory as rival explanations.
Trade and the world economy: Comparative advantage, complementarity, trade agreements and blocs, neoliberal policies, and the World Trade Organization.
Changes from the global economy: Deindustrialization, outsourcing and offshoring, economies of scale, just-in-time delivery, and special economic zones.
Sustainable development: Ecological footprint, resource depletion, and the tension between growth and environmental limits.

Study tips

How to practice Development.

Section-specific guidance that follows from how this material is usually tested.

Compare Rostow, Wallerstein, and dependency theory in a single table with assumptions and criticisms.
Practice interpreting development statistics rather than merely defining them.
Since this unit often falls at the end of the year, schedule it early enough to review twice.

Sample Development questions

Practice questions, not yet expert-reviewed

Original practice questions written to the published framework for this section. No expert has reviewed them, and they are not taken from any official exam. Try each one before you open the answer.

Question 1Foundational
Which economic sector consists of extracting raw materials directly from the earth through activities such as farming, fishing, mining, and forestry?
1. AThe primary sector
2. BThe secondary sector
3. CThe tertiary sector
4. DThe quaternary sector
Show answer
Answer: A. The primary sector
The primary sector takes materials from nature before any processing occurs. The secondary sector is the tempting distractor because it works with those same materials, but its role is manufacturing them into finished goods rather than extracting them.
Key insight: Follow one product through the sectors: growing cotton is primary, weaving cloth is secondary, selling shirts is tertiary, and analyzing the sales data is quaternary.
Question 2Foundational
In Wallerstein's world-systems theory, which category describes countries that mainly supply raw materials and low-cost labor and depend on wealthier economies?
1. AThe periphery
2. BThe core
3. CThe semi-periphery
4. DThe hearth
Show answer
Answer: A. The periphery
Peripheral countries occupy the dependent position in the world system, exporting commodities and labor while importing higher-value manufactured goods. The semi-periphery is the tempting distractor, but it names the intermediate group that both exploits the periphery and is exploited by the core.
Key insight: World-systems theory describes one interdependent global economy in which a country's position, not its isolation, explains its poverty or wealth.
Question 3Intermediate
In Rostow's stages of economic growth, which stage features rapid industrialization concentrated in a small number of leading sectors?
1. ATake-off
2. BTraditional society
3. CThe drive to maturity
4. DThe age of high mass consumption
Show answer
Answer: A. Take-off
Take-off is the third stage, when investment rises sharply and a few leading industries drive sustained growth for the first time. The drive to maturity is the tempting distractor, but it follows take-off and describes the later spread of technology and growth across the whole economy rather than the initial industrial surge.
Key insight: Rostow assumes every country climbs the same ladder, which is exactly the assumption dependency and world-systems theorists reject.
Question 4Intermediate
What term describes the cost savings a firm gains by clustering near other firms in the same or related industries?
1. AAgglomeration
2. BDeglomeration
3. CComparative advantage
4. DOffshoring
Show answer
Answer: A. Agglomeration
Agglomeration lets clustered firms share suppliers, specialized labor, and infrastructure, which is why technology and film industries concentrate in a few districts. Deglomeration is the tempting distractor, because it names the later dispersal that occurs when congestion and rising land costs outweigh those shared benefits.
Key insight: Agglomeration explains why similar firms crowd together even though they compete with one another.
Question 5Advanced
A smelter turns heavy ore into refined metal so that the finished product weighs far less than the inputs. Where does Weber's least-cost theory predict such a plant will locate?
1. ANear the raw material source
2. BNear the consumer market
3. CMidway between the raw materials and the market
4. DWherever labor is cheapest, regardless of transport
Show answer
Answer: A. Near the raw material source
This is a bulk-reducing industry, so shipping the ore is far more expensive than shipping the refined metal, and locating at the input minimizes total transport cost. Locating near the market is the tempting distractor, and it is the correct prediction for bulk-gaining industries such as soft drink bottling, where the product becomes heavier or bulkier during production.
Key insight: Ask which is heavier to move, the inputs or the output, and locate beside whichever costs more to ship.
