					Population Density and Distribution

Name:_____________________

Lab: The purpose of this lab is to understand how the distribution of people in a
country differs from the population density. As well, students will compare
arithmetic densities to physiologic densities in order to understand population
pressures on the land.

   What is the difference between population distribution and population
   density?

   2) Which 3 countries have the lowest percentage of total area
      cultivated? Give one good reason why they have such a small
      proportion of cultivated land. (3 marks)

   3) What do you notice about all the physiological density values in your
      chart compared with their corresponding arithmetic density values?
      (1 mark)


   4) Explain why countries such as Egypt, Iceland, Switzerland, Japan,
      Israel and China have a special challenge in trying to provide
      sufficient amounts of food for their populations. Suggest two
      strategies that these countries might use to keep their populations
      well fed. (3 marks)

   5) When we think of countries where there is chronic hunger, African
      countries such as Chad and Botswana come to mind, yet the number of
      people depending on each square kilometer of cultivated land in these
      countries is not nearly as high as in question 6. What does this say
      about the quality of land in the African countries? (1 mark

   6) Based on the physiologic densities suggest at least 3 countries in the
      world that might be food exporters. (3 marks)

   7) a) Find an example of a country with a high population but a relatively
      low physiologic population density. (1 mark)

      b) Find an example of a country with a low population but a relatively
      high physiologic population density. (1 mark)

      c) Does a high population necessarily lead to a high physiologic
      density? What relationship determines the physiologic density? (1
      marks)


   8) Explain one problem in only using arithmetic population density to
   determine how dense the population of a country is. (1 mark)
