Introductory Sociology: Social Stratification - Global Stratification HighIncome MiddleIncome LowIncome Countries Modernization Theory vs. Dependency Theory vs. World Systems Theory

What It Is

Global Stratification refers to the unequal distribution of wealth and resources among countries worldwide. For instance, the United States is considered a high-income country, while many countries in sub-Saharan Africa are classified as low-income countries. Sociologists care about global stratification because it affects the lives of billions of people, influencing their access to education, healthcare, and economic opportunities.

• Modernization Theory suggests that countries develop economically through a linear process of industrialization and urbanization.
• Dependency Theory argues that wealthy countries exploit poorer countries through unequal trade relationships and economic dependence.
• World Systems Theory views the global economy as a single, interconnected system with core, periphery, and semi-periphery countries.
• Immanuel Wallerstein's World Systems Theory emphasizes the historical development of the global economy.

• The Kuznets Curve describes the relationship between economic growth and income inequality.
• Income inequality is higher in high-income countries than in low-income countries.
• The Human Development Index (HDI) measures a country's well-being based on life expectancy, education, and income.

• Global poverty affects over 700 million people worldwide.
• The Millennium Development Goals (MDGs) aimed to reduce global poverty and improve living standards.
