  1. Doubling Time Project

  2. The time needed for any population to double its size is known as its “doubling time.” For example, if a population grows slowly, its doubling time will be long. If it is growing rapidly, its doubling time will be short.

  3. The following formula is used to calculate a population’s doubling time: Doubling time (in years) = 70 / annual % growth rate • Use the data table below. • Complete the table by calculating the doubling time of human populations for the listed geographic regions.
