pop densities and conse

What is the difference between physiological and arithmetic density?

• The rate at which women have enough babies on average to replace the older generation

• Total number of objects

• Arithmetic density is the number of people supported by an area of arable land while physiological density is the number of people in an area.

• Physiological density is the number of people supported by an area of arable land while arithmetic density is the total number of objects in an area.

What is population density?

• Low cluster of population in a certain region

• Growth of population over time

• Mass production of arable land

• High cluster of a population in a certain region

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

Which of the following describes information a geographer could identify from the map of urban populations in Brazil?

• Urban areas with rapid population growth

• Distribution of high and low incomes

• Areas with negative population growth

• Patterns of arithmetic density within specific regions

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.

Sri Lanka and Australia have about the same population. What data would help you determine which country has a higher physiological population density?

• The area of each country

• The number of farmers in each country

• The total fertility rate of each country

• The amount of arable land in each country

Which of the following best identifies the data for the Eastern Great Rift Valley, shown on the map?

• Low arithmetic density

• High arithmetic density

• Low carrying capacity

• High total fertility rate

Which of the following regions had the smallest percentage of people living in urban areas at the end of the twentieth century?

• Australia

• South Asia

• North America

• Europe

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.
