1Do Now: Monday 11/1On a blank sheet of paper, title it Unit 2: Population & MigrationRespond to the following question:What is the total population of the world?of the US?of Maryland?of Baltimore MSA?of Baltimore City?
2Populations Of the world: 6,878,700,000 Of the US: 307,006,550 Of Maryland: 5,699,478Of Baltimore MSA: 2.65 millionOf Baltimore City: 636,919
3Objective 11/1We will introduce the central concepts behind the geography of populationWe will examine ways that geographers analyze population size and distribution throughout the world
4Homework/Updates:You are responsible to bring your book to class every day.Read Chapter 2 Key Issues before each day’s presentation.You will be held responsible for the vocabulary in each Key Issue that is listed on each day. Be prepared for open/closed note quizzes at any time.Refer to the AP HUG calendar on board or website for reading and quiz schedule.
5Unit 2: Population & Migration Ch. 2 Focus Questions:What factors determine the size, characteristics, movement, and distribution of people throughout the world?How has the world’s population changed throughout human history? Why?Based on a geographic analysis of the world, is it becoming dangerously overpopulated?
6Population Why is it important to study population? 6.5 billion people alive, more than any other time in historypopulation increasing at faster rate than ever in historyall global population growth is concentrated in LDCs
7Did you know...How is the importance of population size and growth represented in the following video?What implications does this information have on our country, and your future?2kBKads
8World Population Trends... Based on the following chart, write a 1 sentence description describing a trend in world population throughout history.What factors account for the recent explosion in population?
9Population Growth The world’s population is growing exponentially. Most of the growth is in LDCsMore MDCs are at 0 population growthSome in Eastern Europe (Russia) are declining in population. Why?Russia recently offered a bonus of 250,000 rubles (about $9,200) to women who would have a second child.
10Population Growth What factors influence population growth... amount of foodbirth rateslife spanculturecontraceptivesTake 2 minutes and identify2 other topics that aredirectly related to populationsize and growth throughoutthe world.
11Population GrowthWhy do you think population is growing most rapidly in LDCs?80% of the world’s pop. live in LDCs in Africa, Asia, and Latin AmericaWhat factors influence population growth or decline?
12KI: 1 -Where is the world’s population distributed? Demography - the study of population characteristics - use data like census statistics(structure, change, dynamics)Demographics - the study of characteristics of the populationdemographic data - specific data used to profile certain groups - used in marketing, political research and campaigningcontroversy behind demographics - “profiling” groups of people
13Expansion of the Ecumene 5000 BC - AD 1900 75% live on only 5% of the Earth’s surface Fig. 2-3 (pg. 50): The ecumene, or the portion of the earth with permanent human settlement, has expanded to cover most of the world’s land area.
14World Population Map Assignment Where do people live throughout the world?4 main regions: East Asia, South Asia, Southeast Asia, western & central Europe, and Northeastern US and CanadaWhat is the distribution of people throughout the world? (density)How do geographers measure this distribution? (arithmetic, physiological, and agricultural density)
15Arithmetic Population Density Fig. 2-4: Arithmetic population density is the number of people per total land area. The highest densities are found in parts of Asia and Europe.
16Arithmetic Population Density This is an example of a choropleth map: each section is shaded according to a common criteria.
21Physiological Density Fig. 2-5: Physiological density is the number of people per arable land area. This is a good measure of the relation between population and agricultural resources in a society.
22Agricultural DensityAgricultural Density: ratio of the number of farmers to the amount of arable land.US and Canada have lower agric. densities than India and Bangledesh.Why would the US have fewer farmers per acre of arable land? What is different about farming in the US vs. India or a more LDC?
23Do Now: 11/3Take out your population map. Review your definitions for arithmetic, physiological, and agricultural density.Respond to the following question:Which measure of density is the best indicator as to whether a country will have enough food to feed their people?Which measure of density would be the best indicator of a country’s level of development?
25Quick Review The most rapid growth in population is occurring in _____ The most populous country in the world is ______A country with a large amount of arable land and a small number of farmers will have a _____ agricultural density.75% of the world’s population lives on 5% of the earth’s surface. The portion where humans live is called the _______.
26Population Growth & Decline Focus Questions What are the basic factors of a society the will determine whether their population grows or declines?What factors influence the fertility and mortality of a country?How does the level of development relate to the fertility and mortality of a country?What are the implications for the current trends in worldwide population growth and decline? Challenges to MDCs and LDCs.
27CIA ReportAssignment: You are a CIA analyst responsible for evaluating and predicting worldwide trends in population growth and decline. Based on the the information below, write an executive summary explaining the relationship between level of development and population growth, and generalize what challenges these data present to MDCs and LDCs. You might be asked to deliver your report to your colleagues in the World Demography Unit, so make it good.The security of our nation depends on it.
28Fertility & MortalityYou have 15 minutes to work in your groups and complete the following:define your measureexplain your map/figure related to your measurecreate a rhyme or hand signal to help remember your measureidentify whether your measure would be high, low, or mixed between MDCs and LDCsexplain why for eachall members of group should be prepared to sharethis will be collected at the end of class
30Reminders Vocab Quiz tomorrow Key Issues 1&2 Chapter 2 Key Issue Worksheets are on website. (Key Issue 2 will not be necessary based on today’s activity.)Read Chapter 2 Key Issue 4 for tomorrow. Be prepared to discuss Malthus’ theory on overpopulation.Books every day.
31Do Now: 11/4Sit in your groups from yesterday and get out your Population Growth and Decline report.You will 4 minutes to discuss your answers with your group.Each member of your group will be responsible for explaining your specific measure, so you must have complete and accurate information.
32Overpopulation How would you define overpopulation? How do geographers define overpopulation?When an area’s population exceeds the capacity of the environment to support it at an acceptable standard of living.What are the variables in this definition?
33What do you think about this? jV_OJIHow might this dramatization relate to a discussion of overpopulation issues?
34Overpopulation? http://www.breathingearth.net/ Do you think overpopulation is a threat facing the world today?What kind of problems emerge from overpopulation?What does overpopulation have to do with topics that we have already studied - like urbanization?
35Do Now: 11/5Pick up a scrap paper and take a seat in your groups that we were in yesterday.Take out your Population Growth Report and be prepared to comment on the following questions:What is the relationship between development and population growth or decline?What future trends do you predict for population sizes in MDCs? LDCs?
36Vocab QuizPick two words. You will write one sentence that relates these two words in a way that demonstrates understanding of both.Example: Malthus & Demographic Transition ModelMalthus predicted that the world population would grow exponentially with no limits, but the Demographic Transition Model shows how the population of Industrialized countries stabilize because people start having fewer and fewer children.
37Objective 11/5We will examine prominent geographic theories regarding overpopulationWe will create a Children’s Book called: The Demographic Transition to demonstrate understanding of said model
38Overpopulation“The [former] director of the U.S. Central Intelligence Agency, Gen. Michael Hayden, when asked to pinpoint which issue was of most pressing concern to him, said that the most troublesome threat facing the U.S. and the world today is not terrorism or global warming, but overpopulation, especially in the poorest parts of the planet.”osses.pdfDo you agree or disagree with this statement?CIA Director, General Michael Hayden
39The rapid growth of the world's population, according to Hayden, may lead to fueling further instability and extremism, along with exacerbating worsening climate change, and making fuel and food much scarcer. Population, Hayden argues, is considered the prime multiplier for all types of human ills.Debate Question: Is overpopulation the greatest threat facing our world today?
40Overpopulated World? Malthus Neo-Malthusians Demographic Transition Model
41Will the World Face an Overpopulation Problem? What is the most immediate challenge that overpopulation of the earth poses to mankind?Food SupplyThomas Malthus - English economist and demographerEssay on the Principle of Population (time of Industrial Revolution population explosion)Basic premise: The population is growing exponentially, however, the food supply only increase arithmetically
42Malthus’ TheoryWhat do you think Malthus proposed as the solution to this crisis?“moral restraint” to produce lower CBRif not, overpopulation will produce high CDR due to disease, famine, war, or other disasters
43Malthus’ Critics What is Malthus really recommending? Why might that be controversial?Malthus assumes that world resources are fixedWhat happened to food production during the Industrial Revolution?Malthus did not understand the Demographic TransitionWhy was Malthus wrong?
44Food & Population, 1950-2000 Malthus vs. Actual Trends Fig. 2-20: Malthus predicted population would grow faster than food production, but food production actually expanded faster than population in the 2nd half of the 20th century.
45Neo-MalthusiansMany believe that a “Malthusian” catastrophe could still occurSustainability - How will we keep up with food demand w/ a pop. of 10 billion?Increasing per capita demand - avg. 1st world citizen consumes 8X the 3rd world citizen. As the world becomes more developed, so will the demand for more food.Natural Resource Depletion - over-consumption of other resources like timber, minerals, energy and non-renewables. Will a world of 10 billion have enough materials to create shelters and energy to heat homes?
46OverpopulationIs overpopulation the greatest threat facing the world today?What are your initial reactions to this question? What do we need to know to be able to debate this question?
47Do Now: 11/8 How do geographers define overpopulation? Who was Malthus and what was his theory regarding world over/population?Why was he wrong?Fig. 2-20: Malthus predicted population would grow faster than food production, but food production actually expanded faster than population in the 2nd half of the 20th century.
48World Population Growth What does world population growth look like on a map?As you analyze the following map, respond to this question: What are the geographic patterns or trends that you see regarding population growth and/or CO2 consumption?
49Demographic Transition Model shows what happens to a country’s population as it becomes industrialized.Countries move forward not backwardsTracks Birth Rate, Death Rate, and Total Population
50Demographic Transition Model Children’s Book You will create a children’s book explaining the demographic transition model. Your children’s book must include the following components:A cover sheetIntroduction to DemographySimple explanations for each of the stages in the DTMConclusion - Why is this model significant? What does this model mean for our world?The book must be written simply and in your own words. Refer to your notes, the text, class presentations, and the internet for the information you need.
51Your Demographic Transition Model 3 colors for Birth Rate, Death Rate, and Total Populationdefine each stage on the back
52World Population Movie While watching the video, fill in as much detail as you can on your Demographic Transition Modelpopulation/animations/world_population /
53Stage 1 Hunting & Gathering Societies unstable food sources high death, high birth, low populationno countries in stage 1 in today’s world
54Stage 2 Agricultural Societies very basic farming - no tech. more stable food sourcessharp increase in populationdeath rate declines sharplymost African countries in stage 2
55Stage 3 Industrial societies mechanized farming children don’t work, more women work - TFR goes downUnited States today (why stage 3 not stage 4?)Birth Rate drops Why?Death Rate already low keeps falling Why?
56Stage 4 Tertiary / Service-Based Societies Birth & Death rates almost equalzero population growthWhen TFE falls below 2, what happens?fewer children - Why?economic liabilitygreater control over fertility - contraceptives

99ObjectiveWe will evaluate how different health threats impact countries differently by applying the epidemiologic transition.
100Focus QuestionsWhat have been, and are today the most significant world health threats?Why and how do different health threats impact different countries?How does understanding these differences help us to prevent and/or eradicate these sicknesses?
101News Report ActivityIn your groups, you will create a news report explaining a specific sickness.In your report, you will address the following information:Where (& when) this sickness would most likely take place.Specific details about your sickness.How is this sickness spread?How worried should people be? What should they do?What will be the likely end result of this sickness?
102Epidemiology Chapter 2 Key Issue 4 Branch of medical science concerned with diseases that impact large numbers of peopleWhy do you think epidemiology is so closely related to geography?
103Epidemiological Transition Explains primary causes of death in each stage of the demographic transitionDeveloped by Omran in 1971
104Epidemiological Transition Stage 1: Stage of Pestilence and FamineWhat causes high CDR in stage 1 of the demographic transition?In stage 1, death is caused by starvation, disease, and general danger of living in the prehistoric world.
106Epidemiological Transition Stage 2: Stage of Receding PandemicsStage 2: What happens during stage 2 of demographic transition?Stage 2 ET: High death rates persist among the poor.Ex. cholera - prevalent in urban areas

113Example: H1N1 Swine Flu What was it? How was it spread? What was the impact?Which stage would it fit into?
115InstructionsDirections: Your group will create a newscast describing, warning, and predicting the impact of a specific sickness. Use your knowledge of the epidemiological transition (pgs ) to provide accurate information on the time and place of the sickness, the cause of its spread, and its likely impact. Your news report can take place at any time and any place in history.
