The Brandt Line is a conceptual boundary proposed in the 1980s by German Chancellor Willy Brandt. It divides the world into two regions: the "Rich North", comprising developed nations with high-income economies, and the "Poor South", which includes developing countries with lower income levels and less industrialized countries. This map visually highlights global economic disparities, with the North predominantly located above the equator and the South below. While the Brandt Line serves as a useful tool for understanding global inequality, modern economic changes and globalization have blurred these distinctions, leading to debates about their current relevance in a rapidly changing world economy.
