1. WORLD POPULATION THROUGH HISTORY…

2. What was the world population at the time of Jesus Christ? 300 million

3. Why?? When did it shoot up? 1850 engines Medicines Technologies

4. BUT WHERE DO THEY ALL LIVE… (AND WHY THERE !?)

5. Imagine the year is 1885. The US Navy is sailing its ships through the Pacific Ocean and to their great surprise, they discover a whole new continent. It is no small island, but a continent almost as big as Australia. No one knows how it was never discovered before, by anyone. The continent is not inhabited so people from Europe and America move in. By the year 1900 it is expected that 250,000 people (1/4 million) will have relocated there permanently. Help the many governments of the new continent plan for future growth. On the map below make your prediction as to where people will settle. Directions: 1. On the map below place 25 dots with a marker to show where you think people will be living in the year 1900. Each dot = 10,000 people. You may place the dots where ever you see fit. The triangles in the middle represent mountains. 2. Any place that you have more than three or more dots close together (size of your pinky nail) you must give a short reason as to why you are putting them so close. Write your justification and draw an arrow to the dots you are referring to.

6. Tropic of Capricorn 22.5 S Pacific Ocean Directions: 1. On the map below place 25 dots with a marker to show where you think people will be living in the year 1900. Each dot you place represents 10,000 people. You may place the dots where ever you see fit. They may be bunched together, spaced apart or some combination of both. Use whatever you know about climate or people’s needs and preferences to help you place your dots. The triangles in the middle represent mountains. 2. Any place that you have more than three or more dots close together (size of your pinky nail) you must give a short reason as to why you are putting them so close. Write your justification and draw an arrow to the dots you are referring to.

7. If you had “first picks”, where would you want to buy land? Pacific Ocean 1. Near water (i.e. 2/3 <300 mi of oceans ) For travel & food sources 2. Potable water sources 3. Flatter land (for crops) 4. Fertile soil (deltas & volcanic ash, so…?) 5. Moderate temperature (mid latitudes) 6. Natural protection (bays) 7. Major “crossroads” points/travel routes (CHOKE POINTS) …any land in the middle? Where are there the most layers overlapping? Click after point #4

8. Click to return to presentation Nile River delta created by soils carried by the river & deposited in the Mediterranean Sea Deltas “grow” the land out into the water but are VERY low & flood easily. Great soil though!

9. East Asia China, Japan, Koreas, Taiwan 1.7 Billion 28% world population

10. South Asia India, Pakistan, Bangladesh, and Sri Lanka 1.4 Billion 23% world population

11. Europe Largely concentrated in urban areas 700 Million 12% world population

12. “Our Place” Largely concentrated in urban areas 300 Million

13. Is the WHOLE world’s population growing…?

14. 1950196019701980199020002010 2020 LOW HIGH POPULATION Americans - Caucasians (whites) Developed countries around the world America - OVERALL: including minority groups and immigrants Positive growth Negative growth Underdeveloped countries around the world

15. 1950196019701980199020002010 2020 LOW HIGH POPULATION Developed countries around the world Underdeveloped countries around the world ACTIVITY: What is happening to the size of the populations in each of the following? Germany WHY? Write down 2 ideas why. Norway Nigeria India Bolivia

16. Reasons for Positive Population Growth: Reasons for Negative Population Growth: Example countries: poor economy poor health care 1) want kids but high infant mortality poor education 2) Little or no birth control or family planning People CHOSE to not have many kids, Is ‘negative’ bad?Is ‘positive’ good? 25 years ago: What do people want INSTEAD money education jobs pets birth control What ‘technology’ allows them to chose? Example countries:

20. 1950196019701980199020002010 2020 POPULTAION PERCENTAGE 30 % Rural, means _________________________ Urban, means _________________________ As a country ages, people relocate where they live. Where do people move from, and where do they move to? Where do most people in the world live in 1950? Rural or Urban? push/pull factors…? 70 %

22. What countries do you suppose these are? (Think about Underdeveloped, Emerging, Developed) Nineteen countries in the world have a negative or zero population growth. Where are they? Russia: will lose 22% of their population by 2050 shrinking 30 million people (from 142.3 million today to 110.3 million in 2050) Japan is expected to lose 21% of its population by 2050 (shrinking from 127.8 million to a mere 100.6 million in 2050).

24. Births - Deaths Growth = 1000 births - 1100 deaths 1000 births - 900 deaths 1000 births - 1000 deaths Put these in order top to bottom: positive, stable, negative

25. Births - Deaths Growth = (partially)

26. Births - Deaths + Growth = Immigration - Emigration Using simple numbers, create and write an example where the population growth would be slightly positive even if the birth rate was lower than the death rate. Be ready to write it on the front board. 2 - 3. 5 - 2. + 3 = 2 But that is the addition to the population, not the rate. Births Deaths Immigration Emigration Natural Increase

27. Using simple numbers, create and write an example where the population growth would be slightly positive even if the birth rate was lower than the death rate. Be ready to write it on the front board. 2 - 3. 5 - 2. + 3 = 2 But that is the addition to the population, not the rate.

28. Rate means change, so you need to know the PAST population. Population 2010 2 people Add in 2011: 2 people What is growth rate as a %? 100% New total in 2011: 4 people

29. How can we SHOW changes in population over time? (positive growth, negative growth,…)

30. 1. What are the three variables in this graph? 2. What percent of the population is under 20? 3. What percent of the population is over 45? 4. Write a ratio for kids to adults:? 5. Estimate and write a ratio for kids to adults in the USA 6. Fill in the blank in the title. 22%! % in Age group Age group Gender ! 10-12%! 2 : 1 (kids) : (adults) 1 : 4 (kids) : (adults)

31. Population Pyramid What do the top 2-3 rows tell you about gender? Where are the “baby boomers” on this pyramid?

32. Which of these communities is a college town? Which is a retirement community? For the bottom left pyramid, explain why the two sides aren’t equal in overall size. For the bottom right pyramid, what problems might this place have to deal with?

33. Complete the Population Growth Activity Sheet

34. Underdeveloped (Early stage) economic stages of development: a Simplistic look Emerging (Middle stages) Developed (Later stages) What are most people doing daily to survive? Agriculture (farming) Agriculture Manufacturing Ag Manufacturing Services White Collar Blue Collar
