In the 1980s, the Brandt Line was developed as a way of showing the how the world was geographically split into relatively richer (North) and poorer nations (South).
- The Brandt line was proposed by Willy Brandt (the German Chancellor) in 1980.
- According to this model: Richer countries are almost all located in the Northern Hemisphere, with the exception of Australia and New Zealand.
- Poorer countries are mostly located in tropical regions and in the Southern Hemisphere.
