12. Graph Review: *What type of graph would be best to show change over time? *What type of graph would be best to show a comparison?

13. Demography The statistical study of human populations. Demographics Statistics (information in number form) about human populations.

14. How can studying demographic statistics be useful? School Administrator Taco Bell Manager Politician Advertising Executive

15. Population Density Average # of people per square mile. In the United States we have about 300 million people and 3,717,792 square miles. What is our population density? About 81 people per square mile

17. Canada’s population is about 32 million and they have 3,851,788 square miles. What is Canada’s population density? About 8 people per square mile

19. Monaco is a microstate in Europe on the Mediterranean coast bordering France and Spain. It’s population is about 33,000 and it has.75 square miles. What is Monaco’s population density? About 44,000 per square mile!

22. Egypt has a population density of 180 people per square mile, but since 90% of the country is desert, most people live along the Nile River.

23. So, what does population density actually tell us? Can you think of a different way to figure the population density of a country? An AVERAGE!!! What does it allow us to infer???

24. Arable land: Land that can be farmed. Measured in arable land, Egypt’s population density is about 9,000 per square mile.

26. Population Distribution *90% of the world’s people live in the Northern Hemisphere. *2/3 of those people live between 20’-60’ North (what latitude region???) *many live in low-lying areas, particularly along fertile river valleys near the edges of continents

27. POPULATION IS NOT EVENLY DISTRIBUTED!

28. TRENDS IN WORLD POPULATION..

29. Culture hearth: A place in which important ideas begin and thereafter spread to surrounding cultures.

30. Ancient examples: *Mesopotamia (Fertile Crescent) *Egypt *China *Olmec, Teotihuacan, Maya *Indus River Valley

32. *Where are these places? *What is it like there? *What is the population density today? Draw a conclusion from this information. Make an observation

34. Let’s review! 1. What is the statistical study of human populations? 2. Why do people study population geography? How is it applied in the “real” world? 3. What three things does population density reflect about a country? 4. Why is the world’s population so unevenly distributed? 5. What terms are associated with population change?
