AP Human Geography Presentation
Chapter 2, Key Issue 1- WHERE IS THE WORLD'S
POPULATION DISTRIBUTED?
Presentation By Komal Chattha

Introduction

• Population is distributed by examining two basic
  properties-concentration and density.
• Density measures to help geographers explain the
  relationship between the number of people and
  available resources

3
Population Concentrations

• I. Introduction
• A. Two-thirds of the worlds inhabitants are
  clustered in four regions- East Asia, South Asia,
  Southeast Asia, and Western Europe.
• I. Cartogram-depicts the size of countries
  according to population rather than land area.

4
Population Concentrations

• II. East Asia
• A. East Asia- 1/5th of worlds population
• B. Region bordering the Pacific Ocean, includes
  Eastern China, the islands of Japan, the Korean
  Peninsula, and the island of Taiwan.
• C. Worlds populous country- China is 5/6th of
  East Asia
• D. More than 1/3rd of the people live in three
  large metropolitan areas- Tokyo and Osaka, in
  Japan and Seoul in South Korea.
• (covers less than 3 of the two countries land
  area)
• E. Urban areas and work at industrial or service
  jobs.

5
Population Concentrations

• III. South Asia
• A. 1/5th of the worlds population
• B. Includes India, Pakistan, Bangladesh, Sri
  Lanka
• C. India- Worlds 2nd largest, population
  country (3/4ths of South Asia Population)
• D. Areas population is concentrated along the
  plans of the Indus and Ganges River, Arabian Sea,
  West of Bengal to the east.

6
Population Concentrations

• IV. Southeast Asia
• A. Worlds fourth largest
• B. Half a billion people live in Southeast Asia
  
• C. Includes Java, Sumatra, Borneo, Papua New
  Guinea, and the Philippines.
• D. River valleys, deltas, Asian mainland

7
Population Concentrations

• V. Europe
• A. Russia forms the worlds third largest
  population
• B. 1/9th of worlds population
• C. Region includes four dozen countries
• I. Germany, England, Belgium, Spain
• D. ¾ lives in cities, ¼ lives on the farmlands.

8
Population Concentrations

• VI. Other Population Clusters
• A. U.S.A, Southeastern Canada
• I. 2 of worlds population
• II. Most Americans are urban dwellers less
  than 5 are farmers.
• B. West Africa
• I. 2 of worlds population (half is in
  Nigeria)
• II. Most West Africans work in agriculture,
  although the region has 6 urban areas with more
  than 2 million inhabitants and 16 with more than
  1 million.

9
Sparsely Populated Regions

• I. Introduction
• A. Relatively few people live in regions that
  are too dry, too wet, too cold, too mountainous
  for agriculture.
• B. Ecumene (vocabulary term)
• I. The portion of Earths surface occupied by
  permanent human settlement.

10
Sparsely Populated Regions

• II. Dry Lands
• A. 20 of Earth
• I. Sahara, Arabian, Thar, Takla Makan, and Gobi
  deserts.
• B. Deserts lack sufficient water to grow crops
  that could feed a large population (irrigation
  systems)
• May contain natural resources, which leds to a
  growth in settlements
• in or near deserts.

11
Sparsely Populated Regions

• III. Wet Lands
• A. Lands that receive very high levels of
  precipitation
• I. South American, Central Africa, Southeast
  Asia
• B. Rainfall average- 50 inches per year.
• C. Hinders agriculture
• Enough food can be grown to support large a
  population

12
Sparsely Populated Regions

• IV. Cold Lands
• A. North/South Poles covered with ice
  (Permafrost)
• B. Unsuitable for planting crops
• C. Some animals can survive, few humans live
  there.
• The polar regions are unsuitable for planting
  crops

13
Sparsely Populated Regions

• V. High Lands
• A. Few people live here
• B. Steep, snow covered, sparsely settled
• I. Switzerland
• A. Only about 5 of the countrys people live
  there
• People may prefer to occupy higher lands if
  temperatures and precipitation are uncomfortably
  high at lower elevations.

14
Population Density

• I. Introduction
• A. Population density is the number of people
  occupying an area of land
• I. Arithmetic, physiological, agricultural
  density

15
Population Density

• II. Arithmetic Density (vocabulary term)
• A.K.A. Population Density
• A. The total number of people divided by the
  total land area
• B. Two pieces of information needed to calculate
  measure- total population and total land area
• C. Arithmetic density enables geographers to
  compare the number of people live on a given
  piece of land in different regions of the world.

16
Population Density

• III. Physiological Density
• A. Physiological density (vocabulary term)
• I. The number of people per unit of area of
  arable land, which is land suitable for
  agriculture.
• A. The higher the physiological density, the
  greater the pressure that people may place on
  the land to produce enough food.
• II. Provides insights into the relationship
  between the size of a population and the
  availability of resources in a region.

17
Population Density

• IV. Agricultural Density
• A. Agricultural Density (vocabulary term)
• I. Ratio of the number of farmers to the amount
  of arable land
• To understand the relationship between
  population and resources in a county, geographers
  examine a countrys physiological and
  agricultural densities together
