Preindustrial Transitional Industrial Postindustrial
![Page 19: 1. The most common population dispersion pattern is](https://reader035.fdocuments.us/reader035/viewer/2022070504/56816758550346895ddc18a6/html5/thumbnails/19.jpg)
15. Nations usually exhibit growth when they are in the
A. Preindustrial phaseB. Transitional phaseC. Industrial phaseD. A and BE. B and C
![Page 20: 1. The most common population dispersion pattern is](https://reader035.fdocuments.us/reader035/viewer/2022070504/56816758550346895ddc18a6/html5/thumbnails/20.jpg)
In both the Transitional phase and the Industrial phase the birth rate is greater than the death rate so exponential growth is a occurring in both of these phases.
However, in the Industrial Phase, the birth rate is decreasing, so the RATE OF INCREASE is decreasing (slowing down of growth rate).

16. Which nation has the greatest population growth rate, using age structure graphs shown.
A. KenyaB. United StatesC. GermanyD. Can not determine, only
percentages given
![Page 22: 1. The most common population dispersion pattern is](https://reader035.fdocuments.us/reader035/viewer/2022070504/56816758550346895ddc18a6/html5/thumbnails/22.jpg)
17. If a country has a growth rate of 2% a year, it will increase in size from 100 million to 400 million in
A. 140 yearsB. 70 yearsC. 105 yearsD. 35 yearsE. 7 yearsF. 5 yearsG. 3.5 years
![Page 23: 1. The most common population dispersion pattern is](https://reader035.fdocuments.us/reader035/viewer/2022070504/56816758550346895ddc18a6/html5/thumbnails/23.jpg)
The population increasing from 100 million to 400 million is two doubling periods.
At a rate of 2% growth per year, a population will increase from 100 million to 200 million in 35 years (70/ 2). In another 35 years it will double from 200 million to 400 million.

21. Which of the following is generally correlated with a lower birth rate?
A. Increased infant mortality rate
B. Greater education level esp. for women
C. Decreased urbanizationD. Lower cost of raising a
child
![Page 29: 1. The most common population dispersion pattern is](https://reader035.fdocuments.us/reader035/viewer/2022070504/56816758550346895ddc18a6/html5/thumbnails/29.jpg)
22. Country Q has a growth rate of 0.8% and a crude death rate of 20 per 1000. There is no net immigration/emigration. What is its birth rate (per 1000)?
A. 100B. 80C. 60D. 28E. 18F. 8
![Page 30: 1. The most common population dispersion pattern is](https://reader035.fdocuments.us/reader035/viewer/2022070504/56816758550346895ddc18a6/html5/thumbnails/30.jpg)
The growth rate of 0.8 % (an increase of 0.8 people per hundred) is equal to an increase in the population of 8 per 1000.
Since there is no net migration, the births (per 1000) must be 8 more than the deaths (per 1000) for this country. So if the death rate is 20 per 1000 the birth rate is 28 per 1000.
