The crude birth rate, the number of births per 1,000 persons, is a measure of the birth performance of a population. Similarly, the crude death rate, the number of deaths per 1,000 persons, is an indicator of death experience of a population.
- Why are both measures called "crude"?
- Why does a developed country like Germany have a crude death rate of 10 while a less developed country like Mexico have a crude death rate of 4?
- Liberia’s has a crude birth rate of 50 and the crude death rate of 18. What is its rate of natural increase ? What is it's crude rate of natural increase (in percent) ?

A. Explain what happens to
- the crude birth rate
- the crude death rate
- and the population growth rate
at each stage of the demographic transition model.
B. Why does the crude death rate fall in stage 2?
C. Why does the crude birth rate fall in stage 3?
D. Why must we be careful in using the demographic transition model to predict the future of less-developed countries currently in the second or third stages?

Look at each of the following population pyramids. What can you tell from the shapes of them about the country's:
- population growth rate? High or low? Declining? Why?
- birth rates? Why?
- death rates? Why?
- Which countries have high amounts of demographic momentum? Why?

A. What are some of the significant causes of declines in total fertility rates in less developed countries?
B. What is meant by "development is the best contraceptive" (p. 122) ?

A. The textbook says: "Although the demographic transition is a compelling and an extremely useful framework for viewing contemporary population change, we must be careful in using it to predict the future of less-developed countries currently in the second or third stages." (p.114) WHY must we use caution?
B. Why must one also exercise caution when using a population simulation model? (p. 126)
Match the population pyramid with the verbal description of a country's demographic composition
description of a country's demographic composition Pop. Pyramid “A country at close to ZPG (zero population growth)”
“A country that has undergone a recent shift from high to low fertility”
“A country with a declining population”
“A country with many temporary immigrant workers”
“A country which shows the demographic effects of World War II”
“A country with rapid population growth”

"Using the understanding you have gained by projecting India’s population pyramids into this hypothetical future, give a carefully worded explanation of how it is possible for a population to continue growing for several generations after women begin averaging only 2 children each. It may be particularly helpful to review your answers for Scenario 2 in Activity 2.
