    Learning Objectives

    By the end of this chapter, you will be able to:

    • State the current size of the human population.
    • Interpret age-structure diagrams.
    • Explain what the demographic transition model represents and describe the societal changes that cause the demographic transition.
    • Describe what happens to birth rates, death rates, population growth rate, and population size as a country moves through the stages of the demographic transition model.
    • Give examples of countries in the different stages of the demographic transition models and match age-structure diagrams with the stages of the demographic transition model.
    • Define life expectancy and explain how it changes as a country moves through the demographic transition model.
    • Define fertility and explain how it changes as a country moves through the demographic transition model.

    Figure \(\PageIndex{1}\): Shows the increase in human population size starting in 1750 and predicted out to 2050. The orange area represents the human population in industrialized countries and the blue/green area represents the human population in less-industrialized (developing) countries. The greatest amount of human population growth will be in less-industrialized countries.
