The concept of Global North and Global South (or North–South divide) is used to describe a grouping of countries along socio-economic and political characteristics. The Global South is a term often used to identify lower-income countries on one side of the so-called global North–South divide, the other side being the countries of the Global North (often equated with developed countries). As such the term does not inherently refer to a geographical south; for example, most of the Global South is actually within the Northern Hemisphere.
