1 Do Now: Monday 11/1 On a blank sheet of paper, title it Unit 2: Population & Migration Respond to the following question: What is the total population of the world? of the US? of Maryland? of Baltimore MSA? of Baltimore City?

2 Populations Of the world: 6,878,700,000 Of the US: 307,006,550
Of Maryland: 5,699,478 Of Baltimore MSA: 2.65 million Of Baltimore City: 636,919

3 Objective 11/1 We will introduce the central concepts behind the geography of population We will examine ways that geographers analyze population size and distribution throughout the world

4 Homework/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.

5 Unit 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?

6 Population Why is it important to study population?
6.5 billion people alive, more than any other time in history population increasing at faster rate than ever in history all global population growth is concentrated in LDCs

7 Did 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

8 World 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?

9 Population Growth The world’s population is growing exponentially.
Most of the growth is in LDCs More MDCs are at 0 population growth Some 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.

10 Population Growth What factors influence population growth...
amount of food birth rates life span culture contraceptives Take 2 minutes and identify 2 other topics that are directly related to population size and growth throughout the world.

11 Population Growth Why do you think population is growing most rapidly in LDCs? 80% of the world’s pop. live in LDCs in Africa, Asia, and Latin America What factors influence population growth or decline?

12 KI: 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 population demographic data - specific data used to profile certain groups - used in marketing, political research and campaigning controversy behind demographics - “profiling” groups of people

13 Expansion 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.

14 World 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 Canada What is the distribution of people throughout the world? (density) How do geographers measure this distribution? (arithmetic, physiological, and agricultural density)

15 Arithmetic 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.

16 Arithmetic Population Density
This is an example of a choropleth map: each section is shaded according to a common criteria.

17 Arithmetic Population Density

18 Arithmetic Population Density

19 Arithmetic Population Density

20 Arithmetic Population Density

21 Physiological 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.

22 Agricultural Density Agricultural 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?

23 Do Now: 11/3 Take 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?

24 Measures of Population Density

25 Quick 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 _______.

26 Population 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.

27 CIA Report Assignment: 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.

28 Fertility & Mortality You have 15 minutes to work in your groups and complete the following: define your measure explain your map/figure related to your measure create a rhyme or hand signal to help remember your measure identify whether your measure would be high, low, or mixed between MDCs and LDCs explain why for each all members of group should be prepared to share this will be collected at the end of class

29 Review IMR CDR Life Expectancy NIR TFR CBR doubling rate

30 Reminders 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.

31 Do Now: 11/4 Sit 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.

32 Overpopulation 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?

33 What do you think about this?
jV_OJI How might this dramatization relate to a discussion of overpopulation issues?

34 Overpopulation?
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?

35 Do Now: 11/5 Pick 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?

36 Vocab Quiz Pick two words. You will write one sentence that relates these two words in a way that demonstrates understanding of both. Example: Malthus & Demographic Transition Model Malthus 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.

37 Objective 11/5 We will examine prominent geographic theories regarding overpopulation We will create a Children’s Book called: The Demographic Transition to demonstrate understanding of said model

38 Overpopulation “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.pdf Do you agree or disagree with this statement? CIA Director, General Michael Hayden

39 The 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?

40 Overpopulated World? Malthus Neo-Malthusians
Demographic Transition Model

41 Will the World Face an Overpopulation Problem?
What is the most immediate challenge that overpopulation of the earth poses to mankind? Food Supply Thomas Malthus - English economist and demographer Essay 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

42 Malthus’ Theory What do you think Malthus proposed as the solution to this crisis? “moral restraint” to produce lower CBR if not, overpopulation will produce high CDR due to disease, famine, war, or other disasters

43 Malthus’ Critics What is Malthus really recommending?
Why might that be controversial? Malthus assumes that world resources are fixed What happened to food production during the Industrial Revolution? Malthus did not understand the Demographic Transition Why was Malthus wrong?

44 Food & 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.

45 Neo-Malthusians Many believe that a “Malthusian” catastrophe could still occur Sustainability - 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?

46 Overpopulation Is 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?

47 Do 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.

48 World 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?

49 Demographic Transition Model
shows what happens to a country’s population as it becomes industrialized. Countries move forward not backwards Tracks Birth Rate, Death Rate, and Total Population

50 Demographic 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 sheet Introduction to Demography Simple explanations for each of the stages in the DTM Conclusion - 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.

51 Your Demographic Transition Model

52 World Population Movie
While watching the video, fill in as much detail as you can on your Demographic Transition Model population/animations/world_population /

53 Stage 1 Hunting & Gathering Societies unstable food sources
high death, high birth, low population no countries in stage 1 in today’s world

54 Stage 2 Agricultural Societies very basic farming - no tech.
more stable food sources sharp increase in population death rate declines sharply most African countries in stage 2

55 Stage 3 Industrial societies mechanized farming
children don’t work, more women work - TFR goes down United States today (why stage 3 not stage 4?) Birth Rate drops Why? Death Rate already low keeps falling Why?

56 Stage 4 Tertiary / Service-Based Societies
Birth & Death rates almost equal zero population growth When TFE falls below 2, what happens? fewer children - Why? economic liability greater control over fertility - contraceptives

98 Do Now Pt. 2 : 11/15 Take out your Unit 2 notes and respond to the following questions: What are the different kinds of health threats / diseases that threaten population growth? Can you give an example of a health threat that would only apply to an LDC? an MDC?

99 Objective We will evaluate how different health threats impact countries differently by applying the epidemiologic transition.

100 Focus Questions What 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?

101 News Report Activity In 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?

102 Epidemiology Chapter 2 Key Issue 4 Branch of medical science
concerned with diseases that impact large numbers of people Why do you think epidemiology is so closely related to geography?

103 Epidemiological Transition
Explains primary causes of death in each stage of the demographic transition Developed by Omran in 1971

104 Epidemiological Transition
Stage 1: Stage of Pestilence and Famine What 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.


106 Epidemiological Transition
Stage 2: Stage of Receding Pandemics Stage 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



109 Epidemiological Transition
Stage 3: Stage of Degenerative and Human-Created Diseases less infectious disease - more chronic disorders from aging (examples?) Cardiovascular (heart) and various cancers

110 Epidemiological Transition
