Using the demographic terms presented in this chapter, compare and contrast the populations of highly
developed and less developed countries. What will be an ideal response?
Concepts to Consider: Highly developed countries have low birth rates, relatively low infant
mortality rates, lower replacement-level fertility, longer life expectancies, higher per capita GNI PPPs,
age structure diagrams with a relatively narrow base, and may have a stationary population; less
developed countries have high birth rates, relatively high infant mortality rates, higher replacementlevel
fertility, shorter life expectancies, lower per capita GNI PPPs, age structure diagrams with
relatively broad bases, and growing populations.
