Chapter 4, Section 2

  1. 1. Chapter 4, Section 2 POPULATION GEOGRAPHY
  2. 2. Goals of Chapter 4, Section 2 <ul><li>To explain the factors involved in the world’s population growth. </li></ul><ul><li>To describe the distribution of the world’s population </li></ul><ul><li>To describe factors that influence population density and carrying capacity </li></ul>
  3. 3. Worldwide Population Growth <ul><li>Question: does the world already have too many people? Can it support more? If so, where? Which people? </li></ul><ul><li>2008 = 6.6 Billion people (according to Wikipedia) </li></ul>
  4. 4. Population Geography Analysis <ul><li>Population Geographer - studies aspects affecting population </li></ul><ul><li>Birthrate: number of live births per thousand population </li></ul><ul><li>according to Wikipedia: Congo is highest with 49.6 per 1000 and Singapore is lowest with 8.2 per 1000 </li></ul><ul><li>Fertility Rate: average number of children per woman during childbearing years throughout lifetime </li></ul><ul><li>according to CIA worldbook factbook: Mali is highest with 7.34 and Singapore is lowest with 1.08 </li></ul><ul><li>--replacement rate: number of children each mother must have to maintain current population --estimated is 2.1 </li></ul><ul><li>WHY might this figure be misleading? Is it more appropriate to analyze country levels rather than world? </li></ul>
  5. 5. Population Geography Analysis <ul><li>Mortality Rate: number of deaths per thousand (also called the death rate) </li></ul><ul><li>QUESTION--What would be an ideal or healthy mortality rate? </li></ul><ul><li>Infant Mortality Rate: number of deaths among infants under age one per thousand live births </li></ul><ul><li>QUESTION--What nations might you assume have a high infant mortality rate? Why? Low rate? Why? What factors affect this? </li></ul><ul><li>according to the CIA Worldfact book the US has 6.3 per one thousand, ranking number 181--behind Cuba, most of Europe, South Korea, Japan, and Singapore…is this surprising? Why or why not? </li></ul><ul><li>Other rates studied: perinatal mortality, maternal mortality, child mortality, standardized mortality rate </li></ul>
  6. 6. Population Geography Analysis <ul><li>Rate of natural increase: also known as the growth rate. Subtract mortality rate from the birth rate </li></ul><ul><li>According to the CIA Wolrdfact book the US birth rate is appx. 14 per 1000 and the death rate is 8 per 1000. </li></ul><ul><li>Rate of increase = Birth rate - Death rate = 14 - 8 = 6 per thousand </li></ul>
  7. 7. Population Pyramid <ul><li>A graphic device that shows sex and age distribution. </li></ul><ul><li>See page 79 </li></ul><ul><li>What does a higher elderly age rate mean for a community or society? Young age? What is most ideal? </li></ul>
  8. 8. Population Pyramid Assessment <ul><li>Students will select a country (the country of your choice more specifically), find data and draw a population pyramid. You may not trace, photocopy, whatever, whatever. This is to assess your knowledge and ability to gather information and formulate a graphic device. It must be of data from no earlier than 2006. Use page 79 as a guide. The pyramid should be neat, clean, organized, accurate. Use color as shown. </li></ul><ul><li>Due Monday October 20!!! </li></ul><ul><li>See rubric on-line </li></ul>
  9. 9. Population Distribution <ul><li>Habitable Lands </li></ul><ul><li>90% of people live in Northern Hemisphere </li></ul><ul><li>Lands between 20 degrees and 60 degrees N latitude have very suitable climate and vegetation conditions = more dense human population </li></ul><ul><li>High population density in coastal regions and river valleys </li></ul><ul><li>Lower population density in polar regions, heavily mountainous regions, desert regions </li></ul><ul><li>More than 1/2 of world’s population lives in rural areas, but dramatically changing </li></ul><ul><li>Largest city in world = city (proper) = Mumbai, India at 13 million </li></ul><ul><li>Let’s look at map on page 80 </li></ul><ul><li>QUESTION: What affect does a higher urban population have on society, nations, the world? </li></ul>
  10. 10. Population Distribution <ul><li>Migration </li></ul><ul><li>1.Push factors - factors causing people to leave homeland and migrate to another region </li></ul><ul><li>Environmental conditions </li></ul><ul><li>War </li></ul><ul><li>Natural disasters </li></ul><ul><li>Persecution </li></ul><ul><li>2.Pull factors - factors that draw or attract people to another location </li></ul><ul><li>Good economy </li></ul><ul><li>High salary </li></ul><ul><li>Climate </li></ul>
  11. 11. Population Density <ul><li>Pop. Den. Is the average number of people who live in a measurable area (such as square mile or kilometer) </li></ul><ul><li>How to calculate? </li></ul><ul><li>Total number of inhabitants/total amount of land </li></ul><ul><li>New Jersey has density of app. 1000 people per square mile and Australia has density of app. 6 people per square mile…what is misleading about these figures? </li></ul><ul><li>Carrying Capacity: the number of organisms a piece of land can support </li></ul><ul><li>QUESTION--What factors can increase carrying capacity? </li></ul>
  12. 12. REVISIT OUR GOALS <ul><li>Can you: </li></ul><ul><ul><li>Explain the factors involved in the world’s population growth </li></ul></ul><ul><ul><li>Describe the distribution of the world’s population </li></ul></ul><ul><ul><li>Describe some factors that influence population density and carrying capacity </li></ul></ul>
