APHG Unit 2.1

The map shows the number of people per unit of land. Which of the following types of data are shown in the map?

• Arithmetic density

• Physiological density

• Agricultural density

• Urban density

Physiological population density differs from crude population density in that physiological density

• examines only the population of cities, while crude density includes the population of cities and rural areas

• is a measure of how density is perceived, while crude density is a measure of specific density

• explains density in terms of people per arable square land unit, while crude density explains density in terms of people per total square land unit

• explains the density of a single housing unit while crude density explains the density of  a group of houses

Physiological population density is viewed as a superior measure of population density for which of the following reasons?

• It yields the average population density.

• It is more reflective of population pressure on arable land.

• It is more reflective of the world’s largest population concentrations.

• It measures the average by dividing total land area by total number of people.

One important feature of the world's population with the most significant future implications is that:

• the natural increase rate is larger every year.
• there are fewer people in the world now than at the peak of the 20th century.
• people are uniformly distributed across Earth.
• the most rapid growth is occurring in the less developed countries.

One thing that arithmetic density cannot account for is what?

• Population distribution on a global scale

• Population Distribution within a country (state)

• Global regions with high population densities.

State A has an agricultural density of 100 people per square kilometer while State B has an agricultural density of 2 people per square kilometer; which country is more developed?

• State A

• State B

This photograph (Fig. 2.3) is a good illustration of:

• the effect of climate on architecture.

• population density.

• physiologic population density.

• infant mortality rate

This map (Fig. 2.5) indicates:

• where fertility rates are high.

• where the world’s largest cities are located.

• where people live.

• where population is decreasing.

This map (Fig. 2.6) shows:

• the range of population densities on Earth.

• population clusters in western Europe, south Asia, east Asia, and northeast North America.

• low population densities in central Australia, northern Canada, and in the Sahara.

• All of the above.

The arithmetic density of population for a country is determined by dividing the total

• population by the number of farmers.

• area of square miles by 5.

• population by the arable land area

• population by the total area.
