AMSCO Chapter 3 Test

Which country below has the lowest arithmetic population density?

• Egypt

• United States

• Austalia

• India

• France

According to the table, which country has a greater need for increased crop yields and imported foods and why?

• Country A: Its physiological density indicates that its farmers do not have the technological resources to grow crops efficiently.

• Country A: The large difference between its arithmetic and physiological densities indicates that it has only a little good farmland.

• Country A: Its high arithmetic and physiological densities indicate that it needs to use a high percentage of its land to grow crops.

• Country B: It has an arable land percentage of 16.8, which is not sufficient for growing enough food to feed everyone.

• Country B: The small difference between its arithmetic and physiological densities indicates it has ample good farmland.

Based on the map, which area is most densely populated?

• Eastern Asia

• Northern Europe

• Western North America

• Central South America

• Southern Africa

Which generalization is best illustrated by the world map above?

• Climate is the primary factor influencing population distribution.

• People are spread out evenly throughout the world.

• The majority of the world’s population lives between 20°N and 60°N latitude.

• More people live in the Western Hemisphere than in the Eastern Hemisphere.

• People have preserved fertile land for farming by choosing to settle heavily in areas with poor farmland.

Which statement about birth is best supported by the pyramid above?

• More births occurred in 1956 than in 1966.

• The number steadily increased between 1956 and 2016.

• More births occurred in 1986 than in 2006.

• The number steadily decreased between 1956 and 2016.

• Fewer births occurred in 2016 than in 2011.

India and the United Kingdom have approximately the same arithmetic density although their landscapes and sizes are quite different. From this we can conclude that the two countries have roughly the same

• level of output per farmer.

• number of people per area of land.

• pressure placed by people on the land to produce food.

• number of farmers per area of land.

• number of people per area of arable land.

If the physiological density in a given country is very high and its arithmetic density is very low, then a country has

• inefficient farmers or farmers that are out of work.

• a large number of farmers, although the number of farmers is not as great as the number of people living in the cities.

• a small percentage of land suitable for agriculture, even if there seems to be plenty of space available to live in.

• too many people for the available resources, particularly in regards to agricultural land.

• too few farmers for the large area of land suitable for agriculture.

Arithmetic density is

• the total amount of land in a country.

• the amount of land available for farming.

• the amount of land available for people to build houses on.

• the total number of people in a country.

• the number of objects in an area.

Which of the following is the correct characterization of population density?

• Arithmetic density is the best ratio to use when describing the "why" of population density.

• Physiologic density is the best ratio to use to describe human health.

• Agricultural density ratios are the best representation of productive agriculture yields.

• A comparison of physiologic densities and arithmetic densities helps geographers understand the capacity of land to yield food for the total population.

• Arithmetic densities provide insight into relationships between resources and population centers in a particular region.

Country A has approximately 100,000 children between the ages of 0 and 14, although it has a high infant mortality rate. It also has 202,000 elderly people who have retired from work, although most continue to live in multi-generational households with their children and grandchildren. Country A also has 310,000 people who can participate in the workforce. We can use these data to calculate that the

• dependency ratio is about 50 percent.

• life expectancy ratio is about 50 percent.

• population ratio is high.

• dependency ratio is about 67 percent.

• dependency ratio is about 33 percent.
