Population Growth
Increase in human population, currently 8 billion, peaking ~2080-2100 before stabilizing or declining.
Formula
Population Growth Rate (%) = ((Births − Deaths) / Total Population) × 100
Real World
Niger has one of the world's highest fertility rates at ~6.7 children per woman, meaning its population is projected to triple by 2050, straining water and food resources.
Exam Focus
Always distinguish between growth rate and total population size — exam questions frequently test whether students confuse declining growth rate with falling population.
