Periphery countries

A world map of countries by their supposed trading status in 2000, using the world system differentiation into core countries (blue), semi-periphery countries (yellow) and periphery countries (red). Based on the list in Chase-Dunn, Kawana, and Brewer (2000).

In world-systems theory, periphery countries are those that are less developed than the semi-periphery and core countries. These countries usually receive a disproportionately small share of global wealth. They have weak state institutions and are dependent on—and, according to some, exploited by—more developed countries. These countries are usually behind because of obstacles such as lack of technology, unstable government, and poor education and health systems. In some instances, the exploitation of periphery countries' agriculture, cheap labor, and natural resources aid core countries in remaining dominant. This is best described by dependency theory, which is one theory on how globalization can affect the world and the countries in it. It is, however, possible for periphery countries to rise out of their status and move into semi-periphery or core status. This can be done by doing things such as industrializing, stabilizing the government and political climate, etc.
