Assignment 33 - Reviewing Human Population Growth

Answer all of the following questions to the best of your ability.

1. According to the concept of the “demographic transition,” a population will go through a period of expansion, but later stabilize at:

a)  its original number

b)  at the maximum carrying capacity of the land

c)  at a population larger than before the transition, but with zero growth

d)  a constant rate of growth

e)  a level where deaths caused by famine and disease equal new births

2. The doubling time of a population:

a)  is two-thirds of the tripling time

b)  is a function of exponential growth

c)  is based on a constant birth rate

d)  Growth rate = (# of births) – (# of deaths per unit time) / (total population)

e)  refers to demographic fertility

3. Decreased death rate and the accelerated rate of human population growth are related to:

I. improved sanitation and health

II. increased food supply

III. control of disease-spreading organisms

a)  I only

b)  II only

c)  III only

d)  I and II

e)  I, II and III

4. The “demographic transition” refers to:

a)  declining population growth rate following rapid growth

b)  democratic mandates for contraceptives to control human population growth

c)  the maximum human population sustainable by the Earth

d)  the transition from population growth to population decline

e)  overpopulation in less developed countries

5. In developing nations, breast feeding slows population growth because:

a)  it increases the average number of years between births

b)  it is healthy and decreases infant mortality

c)  it keeps the children from being hungry

d)  it increases the age at which women will bear their first child

e)  it decreases the frequency of sexual activity

6. Human demography suggests that an improving economy in a country correlates with:

a)  decreased birth rate, increased population growth rate

b)  decreased death rate, increased population growth rate

c)  decreased birth rate, decreased population growth rate

d)  increased birth rate, decreased population growth rate

e)  increased birth rate, increased population growth rate

7. How rapidly a population changes depends most upon (select the best answer):

a)  birth rates d)  maximum lifetime

b)  death rates e)  life expectancy

c)  growth rates

8. The simplest and least controversial means of slowing population growth is:

a)  abortion d)  no sexual activity before marriage

b)  birth control e)  sterilization

c)  delaying first childbearing

9. How does the total fertility rate (TFR) affect the population growth of a nation?

10. Explain the fact that, even though the U.S. total fertility rate is below replacement level, the total population is still growing.

11. Describe three basic ways by which any population with a positive growth rate can achieve zero population growth.
