  1. Calculate the rates of natural increase for the populations
    of Country A and Country B. From the rates of natural
    increase and the data in the table, suggest whether A and
    B are developed or developing countries, and explain the
    reasons for your answers.

  2. Describe where each of the two countries may be in terms
    of their stage in the demographic transition (Figure 6-12,
    p. 134). Discuss factors that could hinder Country A from
    progressing to later stages in the demographic transition.
    3. Explain how the percentage of people under 15 years of
    age in Country A and in Country B could affect the per
    capita and total ecological footprints of each country.
