Option 3 : Natural growth of population.

The correct answer is the natural growth of the population.

  • The population is a dynamic phenomenon.
  • The numbers, distribution and composition of the population are constantly changing.
  • This is the influence of the three processes- births, deaths and migration.
  • There are three main processes of change or growth of population:
    • birth rates
    • death rates
    • migration
  • The natural increase in population is the difference between birth rates and death rates.
  • The birth rate is the number of live births per thousand people in a year.
  • The death rate is the number of deaths per thousand persons a year.
  • Migration is the movement of people across regions and territories.

 Thus, we can say that if a teacher asks the students to calculate the increase in population using births, deaths and in migration and out migration in a particular region between two points of time, the task is given to the concept of natural growth of population.
