Example Question #61 : Population & Migration

Which of the following arguments can be made in opposition to Malthus’ theories on the “principle of population”?

I. Population growth will slow over time due to availability of contraception and the implementation of population control policies.

II. Technological innovation can lead to dramatic improvements in agricultural production.

III. Population growth will continue to rise due to declining death rates and improved access to education.

 

Possible Answers:

I and II only

I, II, and III

II only

III only

I only

Correct answer:

I and II only

Explanation:

Malthus’ “principle of population” states that eventually, population growth will exceed the capacity of agricultural production, which will lead to widespread starvation and suffering. Over the years, many detractors have proposed various arguments in opposition to Malthus’ theories. Two of the most prominent arguments are that a) population growth will slow due to the availability of contraception and the desire of governments to limit growth and b) technological innovation can lead to dramatic improvements in agricultural production, which allow it to keep up with the growth in population.

Example Question #62 : Ap Human Geography

According to Thomas Malthus population grows __________, whereas food production grows __________.

Possible Answers:

parabolically . . . geometrically

arithmetically . . . linearly

linearly . . . exponentially

exponentially . . . parabolically

geometrically . . . arithmetically

Correct answer:

geometrically . . . arithmetically

Explanation:

Thomas Malthus was an economist during the Enlightenment in Europe. In the late eighteenth century he wrote Essay on the Principle of Population (1798) which argues that food production increases arithmetically (linearly) and that population grows geometrically (exponentially). According to Malthus this would mean that eventually the population growth would exceed the growth in food production causing widespread starvation and suffering. Malthus’ arguments continue to be widely influential today.

Example Question #21 : Population Growth & Decline

Why is the Demographic Accounting Equation more comprehensive than the Natural Increase Rate”?

Possible Answers:

It uses past examples and evidence to project into the future.

None of these answers are correct; the “natural increase rate” is more comprehensive than the “demographic accounting equation.”

It takes into account immigration and emigration.

It ignores the Total Fertility Rate, which can be illusory.

It considers the Crude Birth Rate and the Crude Death Rate.

Correct answer:

It takes into account immigration and emigration.

Explanation:

The Natural Increase Rate and the Demographic Accounting Equation are both calculations used to determine the current or projected population growth of a region. The Demographic Accounting Equation is more comprehensive because it takes into account immigration and emigration, whereas the Natural Increase Rate only takes into account the birth and death rates.

Example Question #22 : Theories Of Population Growth & Decline

The growth rate, or replacement rate, needed to sustain a population is ____________.

Possible Answers:

Correct answer:

Explanation:

A stable population requires a growth, or replacement, rate of  There are, on average, 107 boys born for every 100 girls. Therefore, every 100 women need to produce 207 children to sustain a population.

Example Question #21 : Theories Of Population Growth & Decline

The scientific study of a population and its characteristics is known as __________.

Possible Answers:

capacity

demography

None of these

mortality

ecumene

Correct answer:

demography

Explanation:

The study of a population's characteristics is known as "demography." "Mortality" refers to the study of death rates or the actual ability of an individual to die. Ecumene is the geographical area in which people have made their permanent home.

Example Question #22 : Theories Of Population Growth & Decline

What is the stationary population level (SPL)?

Possible Answers:

The level at which a population could grow if given finite resources. 

The level at which a population could grow if given unlimited resources. 

The level at which a population begins before a growth period.

The level at which a population cannot grow any more. 

The level at which a population surpasses the national average. 

Correct answer:

The level at which a population cannot grow any more. 

Explanation:

The stationary population level (SPL) is the level at which a population cannot grow any more.

Example Question #23 : Theories Of Population Growth & Decline

What term is used to describe the number of live births yearly per 1,000 people in a given population?

Possible Answers:

Crude birth rate (CBR)

Basic demographic rate (BDR)

Demographical shift

Mortality rate (MR)

Crude death rate (CDR)

Correct answer:

Crude birth rate (CBR)

Explanation:

The crude birth rate or CBR is the ratio of the number of live births yearly per 1,000 people in a given population.

Example Question #24 : Theories Of Population Growth & Decline

What is the term used to describe the number of deaths in a year per 1,000 people in a given population?

Possible Answers:

Demographic shift

Base mortality

Crude death rate (CDR)

Crude birth rate (CBR)

Basic demographic rate (BDR)

Correct answer:

Crude death rate (CDR)

Explanation:

The crude death rate or CDR is the ratio of the number of deaths yearly per 1,000 people in a given population.

Example Question #21 : Theories Of Population Growth & Decline

What is the formula for determining the natural increase rate (NIR)?

Possible Answers:

NIR = CBR + CDR

NIR = CBR - DSR

NIR = CBR - CDR

NIR = CBR*CDR

NIR = 2*CDR

Correct answer:

NIR = CBR - CDR

Explanation:

NIR (Natural Increase Rate) = CBR (Crude Birth Rate) - CDR (Crude Death Rate)
