                Population Density and Distribution ICA Worksheet
                                Read pages 182-189 in Global Connections.

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.

1. What is the difference between population distribution and population density?
2. Explain what Canada’s population distribution looks like. Does Canada have a high or low population
3. Explain how the physical characteristics of Egypt and Bangladesh have influenced their population
   distribution patterns.
4. Create a formula to explain the difference between arithmetic population density and physiologic
   population density.
5. Complete the chart. Round to one decimal place.

6. Which 2 countries have the lowest physiologic densities? Give a reason for each to explain why they
   have such a small proportion of cultivated land.
7. What do you notice about all the physiological density values in your chart compared with their
   corresponding arithmetic density values?
8. With the arithmetic and physiologic density values graphed in order of smallest total population to
   largest total population (see graph below), what trends or patterns can be found solely on the basis of
   small or large populations? What explanation can you give for the presence or absence of a trend based
   on total population?

9. Explain why countries such as Egypt, Iceland, Switzerland, United Kingdom, Japan, Israel and China
    have a special challenge in trying to provide sufficient amounts of food for their populations. Suggest
    one strategy that these countries might use to keep their populations well fed.
10. 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?
11. Based on the physiologic densities suggest at least 2 countries in the world that might be food
12. Find an example of a country with a high population but a relatively low physiologic population density.
13. Find an example of a country with a low population but a relatively high physiologic population density.
14. Does a high population necessarily lead to a high physiologic density?
15. Explain one problem in only using arithmetic population density to determine how dense the population
    of a country is.
