Examine the figure that presents regional NIR in the developed region of North America as well as in six developing regions. Which of the following accurately describes a way the demographic transition model can be used to study changing populations, using a graph such as this one? A. The regional patterns of immigration are observable; this data can then be related to fertility rates.
B. The regional patterns of urbanization are observable; this data can then be compared to agricultural densities.
C. The regional total fertility rates are observable; this data can then be compared to the population growth rates.
D. The regional population growth rates are observable; this data can then be compared to physiological densities.
E. The regional arithmetic densities are observable; this data can then be compared to agricultural densities.
