This document discusses the concept of global stratification and divides. It describes how societies have historically stratified groups through factors like class, economic status, and race. This stratification led to power imbalances that disadvantaged some groups. In the modern world, global stratification still exists between countries, referred to as the "global divide". The document reviews several theories for explaining global stratification and outlines the historical divisions of the world into the First, Second, and Third Worlds during the Cold War era. It also summarizes the key perspectives of the influential Brandt Report and subsequent analyses on addressing global economic inequalities.
