Which of the following is NOT a major factor affecting the population change in a region?

The correct answer is Occupational composition.

Key Points

• Population change:
  • Population change, defined generally, is the difference in the size of a population between the end and the beginning of a given time period (usually one year).
  • The main components of population change are births, deaths, and migration. 
  • “Natural increase” is defined as the difference between live births and deaths.
  • “Net migration” is defined as the difference between the number of people moving into an area and the number of people moving out.

  • The population change is calculated by the formula -- [Population change = (Births + Immigration) – (Deaths + Emigration)]

Additional Information
