Your answers are highlighted below.
Question 1
Which of the following measures an area’s ability to support life?

A
Agrarian rate
B
Carrying capacity
C
Dependency ratio
D
Fertility rate
Question 1 Explanation: 
Specifically, the carrying capacity is the maximum population size that the environment can sustain indefinitely given the food, habitat, water, and other necessities available in the environment.
Question 2
When one divides a country’s population by its area, one arrives at the country’s

A
Agricultural density
B
Arithmetic density
C
Physiological density
D
Population density
Question 2 Explanation: 
Arithmetic density is the most basic calculation of population density and is easiest to calculate.
Question 3
When one divides a country’s population by its arable land, one arrives at the country’s

A
Agricultural density
B
Arithmetic density
C
Physiological density
D
Population density
Question 3 Explanation: 
Physiological density is a better indicator of a country’s standard of living than arithmetic density but is harder to calculate because it is not always clear about what land can support life.
Question 4
When one divides the total number of people engaged in farming in country by that county’s area, one arrives at the country’s

A
Agricultural density
B
Arithmetic density
C
Physiological density
D
Population density
Question 4 Explanation: 
Generally speaking, a low agricultural density indicates a high standard of living. Fewer farmers usually indicates more technology and less of a need for human labor in food production. But low agricultural density could also indicate starvation.
Question 5
Which of the following climates has historically been the best for supporting human life?

A
Arid
B
Semi-arid
C
Temperate
D
Tropical
Question 5 Explanation: 
Arid climates and semi-arid climates are too dry to support large numbers of people. Tropical climates are usually covered in rainforest and may get too much rain. Temperate climates are just right.
Question 6
Ancient river valley civilizations, such as those on the Tigris and Euphrates or the Nile, originally depended on rivers for

A
Floods
B
Irrigation
C
Protection from nomads
D
Trade
Question 6 Explanation: 
The floods watered the land and provided nutrients from the bottom of the riverbed.
Question 7
A country’s crude birth rate is

A
The number of live births in one year divided by 100
B
The number of live births in one year divided by 1,000
C
The average number of live births across ten years divided by 100
D
The average number of live births across ten years divided by 1,000
Question 7 Explanation: 
Birth rate is not the same as percentage, which would be live births divided by 100.
Question 8
In order to maintain the current population, a country needs a total fertility rate of

A
2.0
B
2.1
C
2.5
D
3.0
Question 8 Explanation: 
A country needs two children to replace their parents. The extra 0.1 is an acknowledgement that not every child reaches child-bearing age.
Question 9
The number of infants who die before reaching age 1 is used to calculate a country’s

A
Crude death rate
B
Infant mortality rate
C
Life expectancy
D
Terminal population rate
Question 9 Explanation: 
The formula is total number of deaths less than age 1 divided by 1,000.
Question 10
The natural increase rate is

A
A synonym for crude birth rate
B
A synonym for total fertility rate
C
Crude birth rate minus crude death rate
D
Crude birth rate minus crude death rate minus net migration
Question 10 Explanation: 
Net migration is needed because some people immigrate to or emigrate from a country. Both immigration and emigration affect the size of a country’s population.
Question 11
A country with a high standard of living will also have a high

A
Crude birth rate
B
Infant mortality rate
C
Percentage of people in farming
D
Rate of female employment
Question 11 Explanation: 
On average, working women have a higher level of education and lower birth rates than non-working women. More infants will live so the infant mortality rate is low. A country with a high level of technology has a lower percentage of people in farming, not a higher percentage.
Question 12
Which of the following would account for a low ratio of men to women?

A
Gender discrimination
B
Plague
C
Starvation
D
War
Question 12 Explanation: 
Gender discrimination usually means women are under-counted. Plagues kill equal numbers of men and women. Starvation usually kills equal numbers of men and women but sometimes results in more female deaths because women give food to their husbands and children first, which may leave no food for the women.
Question 13
According to Thomas Malthus, population increases ____________, food increases _______________, and a food _______________ will result.

A
Arithmetically, exponentially, shortage
B
Exponentially, arithmetically, shortage
C
Arithmetically, exponentially, surplus
D
Exponentially, arithmetically, surplus
Question 13 Explanation: 
According to Malthus, population increases faster than the food supply and food shortages and starvation will result.
Question 14
Malthus did not anticipate

A
An increase in the food supply
B
Later stages of the demographic transition
C
A voluntary decrease in the birth rate
D
Any of these
Question 14 Explanation: 
Malthus did not foresee as stage 3 or 4 of the demographic transition in which people choose to have fewer children. Nor did he foresee the exponential growth of food due to new agricultural technologies.
Question 15
Which of the following stages of the demographic transition has both a high crude birth rate and a high crude death rate?

A
Stage 1
B
Stage 2
C
Stage 3
D
Stage 4
Question 15 Explanation: 
Stage 1 had high death rates due to war, plague, and starvation, and many babies were born as replacements.
Question 16
Which of the following stages of the demographic transition has zero population growth?

A
Stage 1
B
Stage 2
C
Stage 3
D
Stage 4
Question 16 Explanation: 
Crude birth rate and crude death rate are about equal in stage 4.
Question 17
Which of the following stages of the demographic transition would have problems with eldercare?

A
Stage 2
B
Stage 3
C
Stage 4
D
Stage 5
Question 17 Explanation: 
A country has a lower birthrate than death rate in stage 5. Therefore, it has a high dependency ratio with a low number of working people supporting a large elderly population.
Question 18
A country at stage 2 of the demographic transition

A
Has a relatively young age structure
B
Has a relatively middle-aged age structure
C
Has a relatively old age structure
D
Has a relatively high level of technology
Question 18 Explanation: 
Birthrates are very high and life expectancy is low in stage 2.
Question 19
The United States spent most of the twentieth century in which stage of the demographic transition?

A
Stage 2
B
Stage 3
C
Stage 4
D
Stage 5
Question 19 Explanation: 
Stage 3 is moderate growth. It is often the result of migration from rural areas to the city. Urban lifestyles, unlike farm work, are not compatible with large numbers of children.

A
Stage 1
B
Stage 2
C
Stage 3
