1. Unit II: Population Chapters 2,3

2. An understanding of the ways in which the human population is organized geographically provides AP students with the tools they need to make sense of cultural, political, economic and urban systems. Thus, many of the concepts and theories encountered in this part of the course crosscut with other course modules. In addition, the course themes of scale, pattern, place, and interdependence can all be illustrated with population topics. For example, students may analyze the distribution of the human population at different scales: global, continental, national, state or province, and local community. Explanations of why population is growing or declining in some places and not others center on understanding the processes of fertility, mortality, and migration. In stressing the relevance of place context, for example, students may assess why fertility rates have dropped in some parts of the developing world but not in others, and how age–sex structures vary from one country to another. Analysis of refugee flows, immigration, internal migration, and residential mobility helps students appreciate the interconnections between population phenomena and other topics. Environmental degradation may prompt rapid out-migration and urbanization, in turn creating new pressures on the environment. Refugee flows may be magnified when groups have no access to political power because of the way boundaries have been drawn. Rapid immigration to certain parts of the world fosters regional differences in industrial employment and political sentiment toward foreigners. This part of the course also aids in our critical understanding of contemporary population trends by considering how models of population growth and decline, including Malthusian theory, the demographic and the epidemiological (mortality) transitions, change. Given these kinds of understandings, students are in a position to evaluate the role, strengths, and weaknesses of major population policies. For example, how might increasing the education levels of females lead to lower fertility?

19. Why do Populations Rise or Fall in Particular Places? Essential Question:

20. Guns, Germs and Steel http://www.youtube.com/watch?v=CyRa5P6xVo8&feature=player_detailpage#t=153s http://www.youtube.com/watch?v=CyRa5P6xVo8&feature=player_detailpage#t=153s Guns, Germs, and Steel Video Questions Episode 1 1. Jared Diamond has a theory about what causes huge discrepancies among different countries, and he says it boils down to geographic luck. a. What was great about the “ Fertile Crescent ” ? b. Why do the people in New Guinea struggle to strive (what holds them back)? 2. How are people domesticating crops to get bigger, tastier yields? 3. According to Diamond, livestock also play a huge role in a civilization ’ s ability to become rich and powerful. How did the domestication of animals help people? Give examples: a. b. c. 4. List 4 of the animals that have been domesticated What do they have in common? a. b. c. d. 5. How did the ability to domesticate animals help a civilization ’ s ability to become rich and powerful? a. b. 6. What happened to the “ Fertile Crescent ” over time? What caused this?

21. A Population Bomb? Paul Ehrlich publication of The Population Bomb in the 1960’s warned the world’s population was increasing too quickly and outpacing food production Paul Ehrlich Video: http://www.youtube.com/watch?feature=player_detailpage&v=6M73SFtZxy0http://www.youtube.com/watch?feature=player_detailpage&v=6M73SFtZxy0 Thomas Malthus British Economist 1798 published An Essay on the Principles of Population Food supplies grow linearly and population grew exponentially Assumed food production is confined spatially and linearly. Malthus did not foresee Globalization and thus his assumptions were proved false in regards to spatiality

23. Mercantilism, colonialism and capitalism brought interaction among the Americas, Europe, Africa, Asia, and the Pacific. Mechanization of agriculture, improved strains of seed are developed and more fertilizers are used. Bioengineering continues to bring hybrids, genetically modified organisms and countless herbicides and pesticides.

24. Population Growth at World, Regional, National and Local Scales Population change in one place can be affected rapidly by what is going on in another country. Lost Boy video: (stop @2:06) http://www.youtube.com/watch?v=dtP-zfxMFlE&feature=player_detailpage#t=1shttp://www.youtube.com/watch?v=dtP-zfxMFlE&feature=player_detailpage#t=1s Calculating Demographic change within a territory Immigration and Birth – Emigration and death = demographic change The replacement TFR level is 2.1 Doubling Time – every rate of growth has a doubling time, or the amount of time it takes a number to double. 250 million, two thousand years ago to 500 million in 1650 From 1650 to 1820 (170 years), population doubled to 1 billion. 1 billion grew to 2 billion by 1930 2 billion grew to 4 billion by 1975 (45 years)

25. Rate of natural increase (does not take into account immigration and emigration).

26. Today, the pace of world population growth is slowing. Where have Total Fertility Rates (TFRs) fallen below replacement level and why? (p. 45)

27. Population Growth in India Significant demographic variations occur within countries. –In India, growth rates are higher in the east and northeast.

28. Why do Growth Rates Vary in India? 1960s population planning program 1970s country began forced sterilization program for men with 3 or more children. –22.5 million men were sterilized. 2004 state of Uttar Pradesh began guns for sterilization program. Today, most states use advertising and persuasion to lower birth rates.

29. Maharashtra, India. A sign reads “free family planning sterlization operation” closed in 1996.

30. The Demographic Transition in Great Britain Studied the change in birth rates, death rates, and natural growth rates over the course of British industrialization. Found a transition occurred when death rates decline and then birth rates decline, resulting in a low or sustained growth rate.

31. World Birth Rate – number of births in a year per 1,000 people.

32. World Mortality Rate – number of deaths in a year per 1,000 people.

33. The Demographic Transition

34. Stage 1: Low Growth Stage 2: High Growth Stage 3: Moderate Growth Stage 4: Low Growth or Stationary Stationary population level (SPL)?

35. Examine Appendix B at the end of your textbook. Study the growth rate column. Which countries have the highest growth rates? Determine what stage of the demographic transition these countries are in, and hypothesize what may lead them to the next stage.

36. Why does Population Composition Matter? Too Many Men http://www.youtube.com/watch?feature=player_detailpa ge&v=w-xwd_affr4#t=0s http://www.youtube.com/watch?feature=player_detailpa ge&v=w-xwd_affr4#t=0s Essential Question:

37. Population Composition Population Composition is concerned with: –Gender distribution –Age distribution within a country, region, or place.

38. Population Pyramids – Charts that show the percentages of each age group in the total population, divided by gender. For poorer countries, the chart is shaped like a pyramid. Infant mortality rates are high, life expectancy is shorter.

39. In poorer countries, Infant Mortality Rates are usually high, which is reflected in the pyramid shape.

40. In poorer countries, Life Expectancy is usually shorter, which is also reflected in the pyramid shape.

41. Affect of AIDS on population pyramid for South Africa. Predicted population for 2035, without and with AIDS. With AIDS, looks like a population “chimney.”

42. AIDS is leaving large numbers of AIDS orphans.

43. AIDS is creating large numbers of AIDS care-givers. Drawing by a Pokot boy in Kenya, the drawing shows him working in the fields and taking care of his family cattle in order to assist his sick family members.

44. Population Pyramids – Charts that show the percentages of each age group in the total population, divided by gender. For wealthier countries, the chart is shaped like a lopsided vase. Population is aging, TFRs are declining.

45. Age Structure of a Population The populations of many countries are aging. - eg. Europe - eg. Japan Photo credit: H.J. de Blij Bordeaux, France

46. Aging Populations To replace the population, TFR must be 2.1. - TFR in Bologna, Italy is 0.8 - Why are women having fewer children? What are the impacts of an aging population on a country? What are the “solutions” to an aging population?

47. Longer Life Expectancies typically mean higher rates of chronic diseases.

48. In the United States, the national infant mortality rate (IMR) is 7.0. That number represents an average for the country. Think about the differences in IMR in the United States across regions, ethnicities, social classes, and other sectors.

49. How do Governments Affect Population Change? Key Question:

50. Government Population Policies Expansive Population Policies - Encourages population growth. Eugenic Population Policies - Favors one racial or cultural sector over others. Restrictive Population Policies - range from toleration of unapproved birth control to outright prohibition of large families.

51. China’s One Child Policy What are some of the limitations, unintended consequences, and contradictions found in government policies toward population growth?
