Study Notes

  • Population distribution describes how spread out a population is in a given area.
  • Sparse population means fewer people live per unit area.
  • Dense population means a lot of people live per unit area.
  • Moderate population is an average number of people per unit area.
  • Population density is the number of people per unit area.
  • Population density is calculated by dividing the total population by the area.

Factors Affecting Population Distribution

Physical Factors

  • Lowland areas are easier to farm and build settlements, leading to high population density.
  • Moderate climates with sufficient rain and warm temperatures support crop growth, resulting in higher population densities, as seen in Western Europe and Japan.
  • Thick, fertile soils like loams and alluvium boost agricultural production, increasing population density, exemplified by S.E. England.
  • Open woodlands and grasslands are easy to settle in, contributing to moderate to high population densities, such as the Pampas in Argentina.
  • Coastal areas with good access to transport and trade tend to have higher population densities.
  • Availability of water, timber, and minerals like coal, oil, and copper supports development and higher population densities, e.g., Western Europe & Eastern America.
  • Mountainous areas are difficult to farm and build on, leading to low population densities.
  • Very cold, hot, or dry climates inhibit cultivation and are unpleasant to live in, resulting in sparse populations, such as in the Arctic and Sahara Desert.
  • Thin, rocky, and acidic soils result in low agricultural production and low population densities, found in hot deserts and mountainous regions.
  • Dense jungles and swamps are difficult to penetrate and use productively, leading to low population densities, as seen in the Amazon Rainforest.
  • Interior areas of large continents like Africa and Asia struggle to develop, resulting in lower population densities.

Human Factors

  • Large, rich markets, good infrastructure (roads, railways), and a skilled labor force lead to high population densities.
  • Some groups prefer to live together for security and friendship, increasing population densities, e.g., Europeans, Japanese.
  • Stable and fair governments (usually democracies) foster high population densities, as observed in Western Europe and Singapore.
  • Poor trading links, poor infrastructure, and limited job opportunities result in low population densities, such as in Central Africa and the Amazon Basin.
  • Some groups prefer to be more isolated, leading to lower population densities, e.g., Scandinavians.
  • Unstable governments and civil wars result in low population densities, as seen in Afghanistan, Iraq, and Sudan.
  • Few economic resources make it difficult for a country to trade, leading to lower population densities.
