Resource Overview

Students use mathematical formulas to calculate growth rates and doubling times, and to determine the difference between arithmetic and geometric growth.

Students will be able to:
  • Calculate the doubling of an amount and understand how small amounts build quickly with multiple doublings.
  • Explain how birth and death rates affect population change.
  • Explain the difference between arithmetic (linear) and geometric (or exponential) growth.
  • Calculate the rate of natural increase for several countries, as well as their corresponding population doubling or halving times.
  • Analyze countries’ projected population doubling times to project future challenges of demographic changes.
