Population Review Questions: Record answers to the following questions on a separate sheet of paper. Feel free to answer
questions in bullet-point form.
1. Explain the different types of population distribution (clumped, random, and uniform).
2. Draw a population graph and label the following terms: exponential growth, carrying capacity, logistical growth, rapid
growth, stable phase
3. Compare and contrast: Type 1, Type II, and Type III survivors
4. What is the size of the human population in the world? Explain how population size is impacted by the crude birth
rate, crude death rate, immigration, and emigration.
5. Describe the different stages of the demographic transition.
6. Explain how countries can help regulate population size.
7. Compare and contrast R selected and K selected species.
8. Compare and contrast developing and developed countries discussing human health, population size factors, and
fertility rates.
9. What country is predicted to have the world’s largest population within the next few decades? Why?
10. Describe family planning and the factors that affect a country’s fertility rate.
11. Describe an example of when the death rate would decline more rapidly than the birth rate.
