Demographic Transition Model Discussion Assignment

The Chapter 4 Case Study in your textbook describes the recent reduction in population growth in Brazil. Suggest two (2) lessons that can be learned by Brazil’s experience that could be put into place elsewhere to reduce population growth. Next determine the major links between wealth, birth rates, and shared environment within the United States and Brazil. Speculate on one (1) way that a country could attain a sustainable population; then, provide a rationale explaining why you selected that method.

In your own words, describe the demographic transition model as to its effects on population growth; then, take a stance as to whether or not you believe demographic transition is sufficient to produce sustainable population sizes. At the end of the demographic transition, population sizes often decline; speculate whether or not you believe this is a potential problem for future human populations. Justify your response.

Figure 4.10 in your textbook shows age-class diagrams for three (3) different countries. Discuss two (2) ways that the shape of these diagrams can be used to predict future population growth in the regions that they cover. Next, describe what you believe the age-class diagram of the United States looks like, and what it says about our future population growth.
