Unit 2 FACTS, NOTES, AND INFO Flashcards
Understand Unit 2 (23 cards)
Which density type isn’t accurate?
Arithmetic density
What stage of the Demagraphic Transition Model doesn’t correspond with the same stage of the Epidemiological Transition Model?
The 5TH stage of the DTM doesn’t correspond with the 5th stage of the EDM
What are factors that influence the distribution of human populations?
Physical factors such as climate and land
Other factors such as economics, history, economic opportunites (jobs), and political policies
What are 2 methods geographers use to calculate population density
Arithmetic Density and Physiological Density
What is:
Arithmetic Density?
(the # of … per … of land area)
The number of people per unit of land area
What is:
Physiological Density?
(The # of … supported by a … area of … land)
The number of people supported by a unit area of arable land
What’s the difference between all these densities?
(Artihmetic, Physiological, and Agricultural)
Arthmetic density - Supports people per unit
Physiological Density - Supports people per unit of arable land
Agricultural Density - Supports the number of farmers compared to the amount of arable land
(Think agricultural - farmers!)
The higher the what the less the what??
(Arthmetic Density, Physilogical Density and Agricultural Density)
The higher Arithmetic Density, the less land available
The higher Physiological Density, the less useable land for farming
The higher Agricultural Density, the less developed a country is (usually)
What 2 reasons causes population to go up?
Higher life expectancy and Fertility changes
That’s what population growth is based on
Where is population shrinking/growing
Population is shrinking in MDCs while growing in LDCs
Demographic Transition Models are essential tools for understanding population growth patterns.
With 5 stages defined by similar and different characteristics
In Stage 1 - Very high birth and death rates, no natural increase
In Stage 2 - Rapidly declining death rates, very high birth. high natural increase
In Stage 3 - Rapidly declining birth rates, declining death as well. Moderate natural increase
In Stage 4 - Very low birth and death. More old people than young people. Negative natural increase
In Stage 5 - Very low birth and death rates. More old people than young people. Negative natural increase
*No country is in stage 1
The Epidemiological Transition Model explains the common causes of death within each stage of the Demographic Transition Model
Stage 1 - Infectious and parasitic diseases like the Black Death
Stage 2 - Pandemics like the cholera one in London 2+ centuries ago
Stage 3 - Old age, heart disease, and cancer
Stage 4 - Cardiovascular (heart and blood flow) disease. Just that
Stage 5 - Bacteria learning to adapt to hospitals, man made diseases (in the future)
The diseases after each dash (-) is the most common reason for death
Who was:
Thomas Malthus?
A guy that belived starvation would come because the population would ‘outgrow’ the amount of food available.
He was wrong because that didn’t happen and because food production increased over decades. He also overexaggerated a LOT and not even countries like India have outpaced their food production
What happens to women as countries develop?
Women ger more access to school and this causes less children because women are in school more often
🥳
Why do people migrate?
Because of many reasons, such as:
- Escaping from persecution (forced)
- Job opportunities
- Guest working
- Finding a better place for education
What are the 4 types of migration?
Forced and Voluntary migration, Guest Working, and Chain migration
An example of what migration
An example of Forced Migration is slavery
An example of Voluntary Migration is chain migration
What negative aspects can migration cause?
Less job opportunites, more laws enforced, more racism, and more pollution because of a bigger population
Where are the 4 major population clusters?
East Asia, South Asia, Europe, and Southeast asia
What are some reasons for sparsely populated land?
Land thats too dry - Places like deserts lack water to grow food that can feed a lot of people
Land thats too wet - Rain AND heat rapidly deletes nutritients from soil, resulting in less farming
Land thats too cold - Cold regions aren’t suitable for growing food, and only few animals can survive the cold
Land thats too high - The highest mountains on earth and not good for human settlement
What are policies that encourage people to have more children called?
Pronatalist Policies
What are policies that attempt to reduce birth rates called?
Antinatalist policies
Material Vs Non Material Culture
Material - Items people give value to such as clothing and food
Non Matieral - Important ideas in a culture such as different traditions
