13. The replacement level fertility is
A. Exactly 2 children per
couple (on average)
B. Greater in developed
nations
C. Greater in developing
nations
Replacement level fertility is 2.1 in
developed nations compared to 2.5 in
some developing nations- due to infant
mortality.
14. During the transitional phase (phase 2)
of the Demographic Transition model
A.
B.
C.
D.
E.
the birth rate drops
the birth rate increases
the death rate drops
the death rate increases
both A and C
Preindustrial
Transitional
Industrial
Postindustrial
15. Nations usually exhibit exponential
growth when they are in the
A.
B.
C.
D.
E.
Preindustrial phase
Transitional phase
Industrial phase
A and B
B and C
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.
B.
C.
D.
Kenya
United States
Germany
Can not determine, only
percentages given

a year, it will increase in size from 100
million to 400 million in
A.

140 years
70 years
105 years
35 years
7 years
5 years
3.5 years
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.

mi2, the population density is
A.

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 urbanization
D. Lower cost of raising a
child
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.
B.
C.
D.
E.
F.
100
80
60
28
18
8
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.
23. Global population growth rates have
decreased dramatically in the past few decades,
but the world population is still growing rapidly.
This is due to
A. Inaccurate reporting of actual
population numbers
B. Population Momentum
C. A global age structure with an
inward sloping base.
D. Humans have not yet reached
their carrying capacity
24. Deer populations rise and then the wolf

A. A positive feedback
loop.
B. A negative feedback
loop.
C. An irruptive population
growth pattern
D. A cyclic population
growth pattern
