1 Why are some countries more developed than others? DemographicsWhy are some countries more developed than others?
2 Your TheoryWrite a theory that gives at least one reason why some countries are more developed than others.
3 Demographics Demo= people Graph= to write Demographics are numbers (statistics) that tell us about the level of development.Geographers look at how demographic information like population growth, population density, birth rate, life expectancy, literacy rate, per capita GDP to understand the overall health, wealth and development of a country
4 Section OutlineOutline chapter 3 section 1 of your Prentice Hall World Geography text book.Use an idea map/web format with the word “population” in the center.1. Draw three spokes out from the word population and write the main ideas from (bold red headings) at the end of each line.2. Create more branches off the main spokes by using the green subheadings.3. fill in details around the branches with details from the body of the text. Keep in mind that nouns that answer the question what, where, when, who are usually important details that can be connected to the subheadings
5 World Population Cartogram A cartogram distorts land to match some demographic variable. In this case the size of the country is in proportion to it’s population
6 Distribution of World Population Over one half of the world’s population lives in Asia
7 Population Growth by Region Africa doesn’t have the most people but it is the fastest growing continent. At present growth rates of By 2050 the countries of Africa will have a combined population of over 2 billion.In 1950 there were two Europeans for every African. In 2050 there will be two African’s for every European.
8 Largest Populations Country population China 1.3 billion India U.S.304 millionIndonesia232 millionBrazil187 millionPakistan163 millionBangladesh159 millionNigeria148 millionRussia142 millionThe darker the color, the morepeople that live there.
9 Student PracticeColor the countries with the biggest populations on your map
10 Arithmetic DensityDivide the number of people in a place by the size of the placeExample: United States Population (300 million) divided by it’s land size (3,717,796 square miles)Answer: people per square mile in the United States
11 Student Practice What is the arithmetic density of the classroom? What is the physiological density of the classroom?Color the ten most densely populated countries the same color on your map.Which countries are the biggest and the most densely populated?
12 Population Density Country Population Land area Population Density China1.3 billion9.6 km138 (75)India1.1 billion3.3 km336 (33)U.S.304 million31 (180)Indonesia232 million1.9 km117 (89)Brazil187 million8.5 km22 (192)Pakistan163 million796,000198 (58)Bangladesh159 million143,9981,045 (11)Nigeria148 million1.0 km142 (74)Russia142 million17 km8 (220)
13 How Accurate is Arithmetic Density? Is population distributed evenly?What might cause populations to cluster closer together or spread further apart?access to waterarable soillandforms
14 What kinds of climate do most people live in? Population DensityWorld Climates
15 Physiological Density 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.
16 What makes populations grow? Populations grow when births are high and deaths are low.
17 Demographic Transition Model What causes the changes in each stage?Demographic Transition ModelStage 1: Hunting and Gathering, nomadic herdingStage 2: FarmingStage 3: Manufacturing (developing)Stage 4: Services (developed)
18 Demographic Comparisons Assignment Objective: Determine which countries are developed, developing and less developed.Instructions:1-Choose one country from the list of countries on the data chart.2-Compare it’s birthrate, infant mortality, life expectancy, literacy and per capita GDP with the examples on the sheet titled “Demographic Comparisons.”3. Write that country under the example that it matches most closely in at least three categories.
