1. 1/18 I can Identify what a demographer does.
I can identify population density and population distribution.
I can identify what affects population density.
Best guess
What is the difference between a Natural disaster and a Natural hazard.
What is South America?

2. What do you think a demographer does?
Demography 
the study of population patterns and change
Population
all the people of a particular area

3. About how many people live on Earth?
There are currently about 7.5 billion people
Do you think the world is overpopulated? Why or why not?
How did/would you define the term “overpopulated” when you answered this question?
What would indicate that the world is overpopulated?
If it’s not overpopulated, how many people do you think the Earth can support?

4. Could the entire population of the world fit in the United States?
In order to answer this question what would you have to know? What could help you see if this even possible?
Population density
The average number of people in a defined area such as a square mile
Population ÷ area or square=population density
What is the population of this room?
If I give you a 2ftx5ft region of this room and put 10 students in it what would be the population density of the region?
Back to the original question Could the entire population of the world fit in the United States?
3,550,000 is the approximate area of the United States in square miles
Use this figure to calculate the population density of our country if all 7,000,000,000 billion people were placed in it. Round off what would population density be?
The population density would be approximately 2000 people per square mile. Could we survive with 2000 people per sq. mile?

5. Do you think 2000 people per square mile would be ‘crowded’
The population density of the New York City, the largest city in the United States is approximately 26,000 people per square mile. How can they survive?
Why is population density important why do we need it? How can it help us? If I am a leader of New York city why would I want to know population density?
What problems may develop when many people live in a small area?
How might the amount of garbage they produce affect how they live?
How might living in a crowded place affect your quality of life?
How might the number of people in a region affect how available resources are?
Do you see any problems with population density? misleading?

6. Would people be able to live in every square mile of the United States
Would people be able to live in every square mile of the United States? If not, why? Discuss.
population distribution
the pattern, or spread, of people in a given area
Demographers study not only the population density of a region but also population distribution.
What do you think affects population density?

7. Draw two conclusions about the population of the United States based on the map

8. Possible answers
Some areas of the U.S. are much more densely populated than others.
There are more people in the eastern U.S. than the western U.S.
Coastal areas are heavily populated.
There are areas of the U.S. where the population density is less than 1 person per square mile.
The average population density of the U.S. is about 88 people per square mile.

9. Using your and outline of world map
Think back to what you learned about the physical characteristics of Earth in Unit 2 and how might those characteristics impact population density and distribution.
Shade the areas of the world map you think would have the highest population densities.
Work with a partner to discuss where you think the population is most densely populated in the world. Have a conversation tell why you shaded these areas.
Compare your map to the following Map how did you do?

10. Population Density of the Earth. PBS. 14 November 2012 <http://www
Identify specific places with high population densities and make inferences regarding why this might be true.

11. what other factors may influence the distribution of people besides geographic factors. Discuss
Major factors that could affect population distribution.
economic factors such as the availability or lack of jobs and political factors such as the stability or instability of governments.

12. Describe this map. why do you think the map is so distorted
Describe this map. why do you think the map is so distorted. What is the purpose

13. The previous map is a ‘cartogram.’
A type of map used to present statistical information's by distorting the actual size
Cartograms could be used to show energy use, wealth, etc

14. Population Density of the Earth. PBS. 14 November 2012 <http://www
Identify specific places with high population densities and make inferences regarding why this might be true.

17. What do you think this map is about
xxxxxxxxxxxxxx
xxxxxxxxxxxxx

18. population, population density or population distribution.
What is the difference between population density and population distribution?
WHAT is the population of this room? What is the population density of this room per sq. ft.
Describe the population distribution of this class.
