ZIMSEC O Level Geography Notes: Population:Population distribution

  • Population distribution is the spread of people over an area, country or region
  • In the past population distribution was mainly influenced by natural factors such as soil fertility and the environment
  • Whilst natural factors still play a role their effect has been lessened as humans are continually mastering the environment through research and technology
  • Areas such as the northern parts of Zimbabwe (Zambezi Valley) are now inhabitable
  • In the past these areas were uninhabitable due to tsetse flies
  • Areas such as the Lowe-veld which is found on the southern parts of Zimbabwe were dry and susceptible to droughts
  • People tended to shy away from populating these areas
  • Due to technologies such as irrigation the areas are now inhabited and boast thriving irrigation schemes such as the Hippo Valley and Triangle estates
  • Population density is the number of people living in a particular area – usually 1 square kilometre and
  • it  is typically calculated as total population divided by the total land area which they occupy.
  • The world’s population is not distributed evenly across the land area
  • There are physical/natural factors and human factors that determine how the world’s population is distributed
