1. Unit 2: Population and Migration

2. Choropleth mapping!!
Using the blank map of the United States you will create a choropleth map showing the most and least desirable states you would like to live in.
You must create 5 classifications for your map and provide a legend.
The scale is means you could not pay me to live there and 100 means oh yeah, I am in!
Make sure the colors and or shades to use are correct with your legend.

4. Choropleth Mapping!!
Looking at your map, compare it to the sheet with the populations of the states. Inside each state put the current population.
Is there a pattern between how you rated states and the current populations of those states??
What influenced your decision making for this activity?

5. Population Density
Population density – number of people occupying an area of land.
East Asia
South Asia
Europe
Southeast Asia
Northeast North America
West Africa

7. East Asia Eastern China, Japan, Korean peninsula & Taiwan
¼ World’s Population
5/6 live in PRC
China: ½ of population work as farmers (rural)
Japan & Korea
40% live in 3 major cities (Tokyo, Osaka, & Seoul)

8. South Asia India, Pakistan, Bangladesh & Sri Lanka ¼ World Population
¾ live in India
Most are farmers in rural areas

9. Europe 3rd Largest (including European portion of Russia)
1/9 of world population
¾ live in cities
< 10% farmers

10. Southeast Asia
Myanmar, Thailand, Laos, Vietnam, Cambodia, Malaysia, Indonesia, Philippines, & Papua New Guinea
Largest = Java = 100 million
Most work as farmers in rural areas

11. Emerging Population Concentrations
Eastern North America
West Africa
NE U.S. & SE Canada
2% of the world’s population
Most urbanized concentration
>2% farmers
West Africa, including south facing coast & Nigeria
2% of the world’s population
Nigeria = most populous African nation, ½ of this concentration
Most work in agriculture

12. Ecumene vs. Non-Ecumene
The portion of Earth’s surface occupied by permanent human settlement
80% of earth’s landmass
Areas too harsh for settlement
Dry lands
Wet lands
Cold lands
High lands

13. Population Density Arithmetic Density Physiological Density
Agricultural Density

14. Arithmetic Density
The total number of people divided by the total land area
Pros
Easy to compare
Cons
Tells us “where,” but not “why”

15. Physiological Density
The number of people per unit of area of arable land, which is suitable for agriculture
Pros
More meaningful
Cons
Higher = more pressure to produce more food

16. Agricultural Density
The ratio of the number of farmers to the total amount of land suitable for agriculture
LDCs (Less Developed Countries)
Higher agricultural density
More farmers on less land
Less efficient = more farmers on the land.
MDCs (More Developed Countries)
Lower agricultural density
Fewer farmers, more extensive areas
Due to better technology & finances

17. Comparison
What does it mean when we have a large difference between arithmetic & physiological density?

18. Overpopulation
Carrying capacity - The population level that can be supported, given the quantity of food, habitat, water and other life infrastructure present.
Carrying Capacity is the ability of a resource base to sustain a population
Overpopulation – The number of people in an area exceeds the capacity of the environment to support life at a decent standard of living.
Overpopulation
Too many people compared with the resources of region/country

19. Human-Environment Interaction

20. Human-Environment Interaction
Three schools of thought:
Cultural ecology
Environmental Determinism
Possibilism

21. Cultural Ecology
Cultural ecology – Geographic approach that emphasizes human-environment relationships.
Different cultural groups modify the natural landscape in different ways
Based on regions
Based on beliefs
Cultural Ecology is the study of human-environment interaction

22. Theories Possibilism (accepted theory today)
Environmental Determinism (dying theory)
Possibilism – The theory that the physical environment may set limits on human actions, but people have the ability to adjust to the physical environment and choose a course of action from many alternatives.

24. Florida One of the fastest growing states in the United States.
-Good Climate
-Strong and growing economy with many service industry oriented jobs. This means low skilled labor.
-Population is swelling due to migrants from Latin America and wealthy Europeans looking to relocate.

26. Possibilism: The theory that the physical environment may set limits on human actions, but people have the ability to adjust to the physical environment and choose a course of action from many alternatives. If climate change is real and ocean levels are expected to rise, is Miami ready??

27. 1) How will the changes in the coast affect the states populations and economy? 2) Why are rising seas a big problem for many living in Miami? 3) How could rising seas affect other parts of the world? 4) How is florida trying to adapt to the changes in sea levels? 5) Optimistic or Pessimistic, describe the outlook of the future for people living in florida.

28. Why does this matter?
-39% or million Americans live by the coast
-40% of the world’s entire population lives in coastal regions!
