World-systems theory, associated with Immanuel Wallerstein, argues that countries are connected through a single capitalist world economy rather than developing separately. Core countries tend to control finance, advanced technology, high-value production and powerful TNCs. Peripheral countries are more likely to provide raw materials, cheap labour and low-value production, meaning they can be exploited through unequal trade and profit extraction. Semi-peripheral countries sit between the two: they may have growing industries, regional power and some advanced sectors, but they can still be dependent on core countries while also exploiting poorer peripheral countries. Wallerstein described semi-peripheral states as having a mixture of “core-like” and “periphery-like” production processes. The World Bank’s income classifications are not the same as world-systems categories, but they can help students think about global inequalities in wealth and economic power.
This activity helps you apply Wallerstein’s world-systems theory to real countries and their roles in the global economy. You will classify countries as core, semi-periphery or periphery, then use the feedback to explain how global inequality works through trade, labour, technology, finance, raw materials and transnational corporations. The categories are simplified for classroom use: countries can change position over time, and some countries contain both “core-like” and “periphery-like” regions or industries. This makes the activity useful for AO2 application and AO3 judgement, because you need to decide which role fits best and explain why. World-systems theory is part of the AQA Global Development focus on theories of development, underdevelopment and global inequality.
World Systems Map Challenge
Classify each real country as mainly core, semi-periphery or periphery in world-systems theory. The aim is not to label countries permanently, but to apply Wallerstein’s ideas about global power, trade, production and exploitation.
Core
High-income, powerful states that tend to control finance, advanced technology, TNCs, high-value production and global decision-making.
Semi-periphery
Countries with mixed roles: industrialising, regionally powerful, sometimes exploited by the core but sometimes exploiting the periphery.
Periphery
Countries more likely to provide raw materials, cheap labour or low-value production, with less control over trade and profits.
Revision summary: world-systems theory
- Core countries tend to control high-value production, finance, technology and TNC ownership.
- Semi-peripheral countries have mixed roles: they may manufacture, export, industrialise and act as regional powers, while still facing dependency on the core.
- Peripheral countries are more likely to be locked into raw material exports, low-wage labour or low-value production.
- Exploitation works when value flows from low-paid labour and raw materials in the periphery towards profits, brands, finance and technology controlled in the core.
- AO3 judgement: real countries do not always fit neatly into one box; some have core-like cities or industries alongside peripheral regions or workers.

Fishbowl Debate: Which Feminism Best Explains Inequality?
One of the most useful ways to help students evaluate feminism is to get them comparing different feminist explanations directly. Students often understand the basic differences between liberal feminism, radical feminism and Marxist feminism, but find it harder to judge which explanation is strongest when applied to real patterns of social inequality. The Fishbowl Debate…
