population density

Population density is a measure of the average population per square mile or kilometer of an area and measures how crowded a place is

Population distribution

The pattern of human settlement or the spread of people across the Earth.

what factors encourage a higher population

Transportation networks, trade routes, roads, and train lines encourage a higher population

what happens if the scale of analysis changes?

relevant of certain factors such as climate, elevation, and industrialization changes as well

Climate can also explain what

Can’t explain population distribution at a state Lake California

What is social stratification?

The hierarchical division of people into groups based on factors such as economic status, power, and/or ethnicity

What are cities characterized by?

Regions and neighborhoods where the local population shares a characteristic that distinguishes it from other neighborhoods

what type of density measure?

A regions population

what does psychological type of density measure?

The population by land

what type of agriculture type of density measure?

The number of farmers to the area of arable land

How do you calculate arithmetic density?

Calculate by dividing a regions population by its total area

how do you calculate psychological density?

Calculated by dividing population by arable land

How do you calculate agriculture density

Divide the number of farmers to the area of arable land

what is the significance of arithmetic density

tells us the population in more simple terms

what is the significance of physiological density

tells us the percentagr of the region’s land capable of growing crops

What is the significance of agriculture density?

Shows the percentage of farmers able to produce food

how does time and scale affect population densities?

Time influences population density at a local skill

how does distribution of population demonstrate human choices

these choices reflect their values such as whether they choose to live in density, settled urban areas in cities or rural areas that are characterized by the presence of farming and agricultural activities

How does population density impact economic decision?

What are the pros for high density areas?

The neighborhoods usually feature apartment and buildings that include many households

cons for high density areas

contamination of the water supply for a downtown area can make thousands of people ill and disease spread

define overpopulation

having more people than it can support

define carrying capacity

the number of people a region can support w/out damaging the environment

influence of time

the carrying capacity of a region can change over time

influence on cities

cities could be built on land w/boow carrying capacity such as where the soil is not ideal for farming

significane of density

In addition to agriculture, Many other aspects of the environment are affected as population density increase increases
