Population Distribution and Density

Population Distribution at the Country Scale

• Issue: Arithmetic population density can be misleading for large areas like countries; it fails to reflect population clustering.

• Learning Objective: Understand how population distribution and density impact society and the environment.

Egypt

• Population (2020): $99,413,000$

• Arithmetic Density: $257$ people/sq mi

• Physiological Density: $9,182$ people/sq mi

  • Reflects high concentration ($95$% of population) along the fertile Nile River Valley and Delta, which is only approximately $5$% of Egypt's land area.

  • High agricultural density (exceeding $695$ farmers/sq mi) suggests reliance on rural labor, less developed farming, and pressure on food supply, necessitating imports.

Canada

• Population (2020): $35,882,000$

• Arithmetic Density: $9$ people/sq mi

• Physiological Density: $194$ people/sq mi

  • Reflects population concentration ($90$% of population) along the southern border with the U.S. (within $100$ miles).

  • Southern regions offer milder climate, longer growing seasons, fertile soils, and access to Great Lakes/St. Lawrence Seaway, benefiting from U.S. economic connections.

  • Vast majority of its enormous territory is sparsely inhabited or inhospitable.

Comparison & Key Differences

• Both countries exhibit clustered populations in small land areas, masking vast uninhabited regions.

• Canada's land area is nearly $10$ times that of Egypt, but its population is just over one-third.

• Canada's arithmetic and physiological densities are significantly lower than Egypt's, indicating its larger size and smaller population.

• Canada is economically wealthier (global core) than Egypt (periphery).

• Population density numbers alone provide only a partial story of a country's conditions.
