Global patterns of population numbers, densities and change rates
Population is not spread evenly across the world. Some regions hold billions of people, while others are nearly empty — and those numbers keep changing at very different speeds.
Real World
Sub-Saharan Africa has the world's fastest population growth rate (around 2.7% per year), meaning countries like Niger — with a fertility rate above 7 — will see populations double within a generation despite high mortality rates.
Exam Focus
Distinguish clearly between population numbers, density, and growth rate in your answer — conflating these terms is a common mark-losing error.
