Chapter 2 Learning Guide – Population Key Issue 1 – Where is the World’s Population Distributed? Pgs. 44 – 53 Population Concentrations 1. The world’s population is highly clustered, or concentrated in certain regions. FOUR major population concentrations are identified in the text. Shade and label the areas of these concentrations on the map in red. TWO smaller concentrations, or emerging clusters, are also identified. Shade and label these areas on the map in blue. 2. In the boxes below, make note of significant facts, features, countries involved and characteristics of the four most important population concentrations and two secondary ones. EAST ASIA – Eastern China, Japan, Korean SOUTH ASIA – India, Pakistan, peninsula, Taiwan Bangladesh, Sri Lanka - 25% of world’s population - 25% of world’s population - India 2nd most populous country - China most populous country in the world - Most people concentrated on plains of - Chinese population clustered near Indus & Ganges rivers or coasts of Pacific coast but ½ people live in rural Arabian Sea or Bay of Bengal areas & farm - Most people are farmers in rural areas - Japan/S. Korea – 40% live in 3 metro - 25% live in urban areas areas (Tokyo, Osaka, Seoul) which is 3% of land area - 75% live in urban areas & work in industry & service jobs SOUTHEAST ASIA – Islands EUROPE EASTERN NORTH th AMERICA – Along east in Pacific & Indian Oceans - 1/9 of world’s - 4th largest cluster with coast west to Chicago population with 4 dozen - 2% or world’s population 600 million people countries - Indonesia world’s 4th - 75% live in cities - Largest population in most populous country - Less than 10% farm western hemisphere - Population clustered in - Population concentration - Most people in urban S.E. tip of Asian mainland near coalfields as source areas - Most people are farmers of energy for industry - Less than 2% farm in rural areas - Dense roads/rail - Don’t produce enough WEST AFRICA – south food for themselves facing Atlantic coast - Food is imported - 2% of world’s population - 50% living in Nigeria (most populous African country) - Most people farm - 16 urban areas Sparsely Populated Regions 3. Define ecumene: The portion of the Earth’s surface occupied by permanent human settlement 4. What would non-ecumene mean? The portion of the Earth’s surface unoccupied by permanent settlement 5. List the four “lands” which are sparsely populated in Earth in the table below. For each region, briefly explain the reason that makes it inhospitable for human habitation. Sparsely Populated Land Reason for Inhospitality Dry Lands Unable to grow crops; no intensive agriculture Wet Lands 50-90 inches of rain per year; rain & heat deplete soil nutrients hindering agriculture Cold Lands High Lands Ground permanently frozen (permafrost); unsuitable for planting; few animals survive Snow covered mountains; steep land; sparsely settled 6. Use the maps on page 49 to prepare a sketch map that shows non-ecumene and very sparsely inhabited lands. Population Density 7. Define arithmetic density: The total number of people divided by total land area 8. Define physiological density: The number of people supported by a unit area of arable land (suited for agriculture) 9. What occurs the higher the rate of physiological density? Greater pressure people place on the land to produce enough food to feed its people 10. Define agricultural density: The ratio of farmers to the amount of arable land Chapter 2 Learning Guide – Population Key Issue 2 – Where Has the World’s Population Increased? Pgs. 53 – 56 1. Define crude birth rate (CBR): Total number of live births in 1 year for every 1,000 people 2. Define crude death rate (CDR): Total number of deaths in 1 year for every 1,000 people alive 3. Define natural increase rate (NIR): Percentage a population grows in 1 year (subtract CDR from CBR) Natural Increase 4. What is the NIR today? 1.2% 5. When did the global NIR peak, and what was it? 1963 at 2.2% 6. About how many people are being added to the world’s population each year? 80 million 7. Define doubling time: The number of years needed to double a population assuming a constant rate of natural increase 8. In what world regions is most growth occurring? LDCs – S. Asia, Sub-Saharan Africa, E. Asia, S.E. Asia, Latin America, Middle East Fertility 9. Define total fertility rate (TFR): The average number of children a woman will have throughout childbearing years 10. What is the global “average” TFR? 2.6 11. Note the rates and locations of the global “highs and lows” in TFR. 6.0 in Sub-Saharan Africa & 1.9 in Europe Mortality 12. Define infant mortality rate: The annual number of deaths of infants under 1 year of age compared to total live births 13. Define life expectancy: The average number of years a newborn can expect to live at the current mortality levels 14. How are these mortality rates distributed globally, in terms of the developed and developing worlds? The infant mortality rate in higher in LDCs & life expectancy is lower. The infant mortality rate is lower in MDCs & the life expectancy is higher Chapter 2 Learning Guide – Population Key Issue 3 – Why is Population Increasing at Different Rates in Different Countries? Pgs. 56 – 66 The Demographic Transition 1. The demographic transition is a ____process______ with several ___stages___ and every _____country______ is in one of the stages. 2. Fill in the chart below with characteristics describing each stage in the demographic transition model (CBR, CDR, NIR, etc.). Characterize the amount of growth of each stage (low, moderate, high, etc.). Stage 1 Low Growth - Agricultural Rev. - High CBR & CDR - NIR was zero - Population was unchanged Demographic Transition Model Stage 2 Stage 3 High Growth Moderate Growth - CBR drops sharply - Industrial Rev. in N. America & - CDR drops slowly Europe - NIR modest - Medical Rev. in - Gap between CBR Africa, Asia, Latin & CDR narrows America - CBR grows - CDR plummets - NIR high & population grows rapidly Stage 4 Low Growth - CBR declines to equal CDR (both very low) - NIR is zero - TFR of 2.1 produces ZPG 3. Read about how England passed through the various stages of the model on page 59 with Figure 217. Describe a historical event for stages 1 and 2 and a cultural attitude for stage 4. Demographic Stage 1 Event Stage 2 Event Stage 4 Attitude Transition Model in Women have Between 1250 & Industrial Rev. England… 1350 population spurred decided to have declined by 2 improvements in less children…TFR million due to public health so below 2.1 Black Death CBR was high & CDR declined Population Pyramids 4. The shape of a pyramid is primarily determined by what demographic rate? Crude birth rate in a community 5. What is the dependency ratio? Number of people too old or young to work compared to people of working age 6. What age groups are categorized as “dependent”? 0 to 14 & 65+ What does the 7. “graying” of a population refer to? The growing population of older people that places a burden on gov'ts to meet the needs of adequate income & medical care 8. What is the sex ratio? The number of males per 100 females 9. What types of countries/regions are likely to have more males than females? Why? LDCs due to the mortality rate of women during childbirth Countries in Different Stages of Demographic Transition 10. In the chart below, which represents the four stages of demographic transition, identify the country and where it is located which is in that stage and briefly describe how it got to that stage. Stages of Demographic Transition: Example Countries Stage 1 Stage 2 Stage 3 Stage 4 Denmark – Europe Chile – S. America No Country in Cape Verde – W. - Entered stage in Stage 1 Africa - Reached ZPG 1960s - Entered stage in - Elderly & young - Drop in CBR 1950s percentages are - CDR dropped due - Gov’t family the same planning (since to reduction in - With medical removed) malaria advances, elderly - Reduced income - CBR fluctuates population - Unemployment due to number of increasing women in childbearing years at a given time Demographic Transition and World Population Growth 11. How many countries are in Stage 1 of the demographic transition? Zero 12. What portion are in Stages 2 and 3? Majority of countries 13. And in Stage 4? Very few countries 14. Identify the two “big breaks” in the demographic transition and their causes. 1st Break – Drop in death rate due to technological innovation has been accomplished everywhere. 2nd Break – Drop in birth rate due to changing social customs has yet to be achieved in many countries 15. Complete the following statement: The first break came to Europe and North America as a result of…the industrial revolution which produced medical advances. 16. Complete the following statement: The first break came to Africa, Asia and Latin America as a result of…injections of medical technologies from Europe & N. America instead of arising within those countries. Chapter 2 Learning Guide – Population Key Issue 4 – Why Might the World Face an Overpopulation Problem? Pgs. 66 – 73 Malthus on Overpopulation 1. Complete the chart below to describe the views and theories of various population theorists. Thomas Malthus Neo-Malthusians Critics of Malthus - Large population could - World population rate - In LDCs there is a wider growing faster than food gap between population stimulate economic growth & resources growth & food production supply - World population growth - Generates more - Population grows geometrically while food is outstripping many customers & improves resources (clean air, technology supply grows farmland, fuel) not just - Lack of economic arithmetically food development is a result of - Today – 1 person, 1 food unit unjust social & economic institutions not population - 50 years – 4 people, 3 growth food units - There are enough - 100 years – 16 people, 5 food units resources to go around & should be shared equally - More consumers create more jobs Declining Birth Rates 2. right? With regard to food production 3. Where was Malthus In what way was Malthus mistaken? Population growth increased more slowly than food supply 4. What two strategies have proven successful to lower birth rates? Reliance on economic development & distribution of contraceptives 5. Take notes on important facts regarding the distribution of contraceptives. In LDCs demand is greater than supply. Contraceptives more effective if distributed cheaply & quickly. Use of contraceptives low in Sub-Saharan Africa. 2/3 of women use them in Latin America & Asia. Contraceptives are opposed in several religions (Catholicism, Muslims, Hindus). World Health Threats 6. What is “epidemiologic transition”? Distinctive causes of death in each stage of the demographic transition 7. Complete the chart below with notes on the stages of epidemiologic transition. Stages 1 and 2 Stage 1 – Pestilence & famine - Black Plague - Europe & China Epidemiologic Transition Stages 3 and Possible Stage 5 4 Stage 3 – Stage 5 – Reemergence of infectious & parasitic diseases Degenerati create higher CDRs ve & 1. human volution of infectious diseases that are resistant to created drugs diseases 2. overty keeps people from affording treatment for Cardiovasc infectious diseases ular 3. disease & mproved travel spreads infectious diseases cancer rapidly - Infectious diseases decline Stage 2 – Pandemics - Cholera - Crowded industrial cities & poor neighborho Stage 4 – ods Delayed degenerati ve diseases - As a result of medical advances life can be prolonged even with degenerati ve diseases
