  10. Population Distribution Where are the world’s population clusters?

  11. Distribution of World Population • Population concentrations • The four largest population clusters • East Asia, South Asia, Southeast Asia, Western Europe • Other population clusters • Sparsely populated regions • Dry lands – Cold lands • Wet lands – High lands • Population density • Arithmetic density • Physiological density • Agricultural density

  12. Population concentrations • The four largest population clusters • East Asia, South Asia, Southeast Asia, Western Europe • Other population clusters

  14. World Population Distribution & Climate Zones Fig. 2-2: World population is unevenly distributed across the earth’s surface. Climate is one factor that affects population density.

  17. Is this a Population Distribution Map?

  18. Ecumene • The inhabited areas of the world, as opposed to the non-ecumene which is sparsely or not at all inhabited. • The ecumene of a nation is its more densely inhabited core. • These very simplified classifications pose difficulties of delimitation.

  19. Expansion of the Ecumene5000 BC - 1900 AD Fig. 2-3: The ecumene, or the portion of the earth with permanent human settlement, has expanded to cover most of the world’s land area.

  35. Global Population Distribution

  36. Population Density • Population density is the measure of the number per unit area. • It is commonly represented as people per square mile (or square kilometer), which is derived simply by dividing... • Total area population / land area in square miles (or square kilometers)

  37. Population Densities • North America - 32 people per square mile • South America - 73 people per square mile • Europe - 134 people per square mile • Asia - 203 people per square mile • Africa - 65 people per square mile • Australia - 6.4 people per square mile
