  1. Human GeographyBy James Rubenstein Chapter 2 Key Issue 1 Where is the World’s Population Distributed? S. Mathews

  2. Cartogram a map that depicts a country’s size by population rather than land area S. Mathews

  3. Population Cartogram Displays Countries by Population Size S. Mathews

  4. Population Distribution S. Mathews

  5. Population Concentrations S. Mathews

  6. Frank and Earneston Overpopulation S. Mathews

  7. Two-thirds of the world’s inhabitants are clustered in four regions • East Asia • South Asia • Southeast Asia • Europe S. Mathews

  8. Region Similarities • 2/3rd of WP live within 300 miles of ocean • Occupy low lying fertile areas in temperate climates • Most in Northern Hemisphere S. Mathews

  9. East Asia • 1/5th of WP • 5/6th of regions people live in the People’s Republic of China • 2/3rd of PRC live in rural area • 3/4th of Japanese and Koreans live in urban areas S. Mathews

  10. South Asia • 1/5th of WP • Most people are concentrated along the plains of the Indus and Ganges Rivers or along India’s coastline • 1/4th of population live in urban areas S. Mathews

  11. Southeast Asia • ½ billion people in region • Indonesia, 13,677 islands, is 4th most populous country • The 3 Asian regions have ½ of WP, and live on 1/10th of world’s land area (*for 2000 years) S. Mathews

  12. Europe • Third largest population cluster • 1/9th of WP • 3/4th of population live in urban areas • cannot produce enough food S. Mathews

  13. Other Population Clusters • 2% of WP live in northeastern U.S. and southeastern Canada • 2% of WP live in West Africa, with ½ living in Nigeria S. Mathews

  14. Sparsely Populated Regions S. Mathews

  15. Frank and Earneston population concentrations S. Mathews

  16. Ecumene the portion of the Earth’s surface occupied by permanent human settlement. S. Mathews

  21. Ecumene Facts • It has increased over time • Still, approximately 3/4th of WP live on 5% of Earth’s surface S. Mathews

  22. Climate Regions of the World S. Mathews

  23. Dry Lands • 20% of Earth’s surface is too dry for farming • Largest desert regions - in N. Hemisphere between 15oN and 50oN - in S. Hemisphere is in Australia • Contain most of the World’s oil reserves S. Mathews

  24. Wet Lands • Located near the equator between 20oN and 20oS • Rainfall averages between 50 and 90 inches annually • Rain and heat leach out nutrients • Seasonally wet lands can produce enough food for large populations S. Mathews

  25. Cold Lands • Permanently covered with snow and ice or permafrost • Receive less precipitation than some Central Asian deserts S. Mathews

  26. High Lands • Steep, snow-covered and sparsely settled • Population preference for highlands is linked to uncomfortably high temperatures at lower elevations S. Mathews

  27. Population Density S. Mathews

  28. Population Density The number of people occupying an area of land. • Arithmetic • Physiological • Agricultural S. Mathews

  29. Arithmetic Density the total number of people divided by total land area. S. Mathews

  30. S. Mathews

  31. Density By Country • The United States; 78 people per sq. mi. • Bangladesh; 2,640 people per sq. mi. • Canada; 8 people per sq. mi. • Egypt; 185 people per sq. mi. S. Mathews

  32. Density Within a Country • New York County; 67,000 people per sq. mi. • Loving County, Texas; 0.1 people per sq. mi. • Delta and Nile River Valley; 9,000 people per sq. mi. S. Mathews

  33. Arable Land that is suitable for agriculture. S. Mathews

  34. Physiological Density the number of people supported by a unit of arable land. S. Mathews

  35. S. Mathews

  36. Physiological DensityBy Country • The United States; 404 people per sq. mi. • Egypt; 9,073 people per sq. mi. S. Mathews

  37. Physiological Facts • Large physiological density indicates higher pressure on arable land to produce enough food • Comparing arithmetic and physiological densities can indicate the capacity of a country to feed its population S. Mathews

  38. Agricultural Density the ratio of the number of farmers to the amount of arable land. S. Mathews

  39. Agricultural Facts • MDCs have lower agricultural densities because technology and finance require fewer farmers. • Physiological and Agricultural density are used to understand the relationship between population and resources. S. Mathews

  40. Measures of Density in Selected Countries S. Mathews
