  3. The shift from rural to urban areas is often linked to industrialization and economic development.
  4. Urban areas are characterized by higher population density and infrastructure development compared to rural areas.
  5. Urbanization typically occurs in phases, beginning with industrial

Demographic transition model

  1. The Demographic Transition Model (DTM) explains the transition of population growth through different stages of economic development.
  2. The model is divided into five stages, each representing changes in birth rates, death rates, and overall population growth.
  3. The DTM is based on historical population trends in industrialized countries.
  4. Stage 1: High Stationary Stage
    • Characterized by high birth rates and high death rates.
    • Population

Growth trends

  1. Population growth refers to the increase in the number of people over a specific period.
  2. Growth trends are influenced by birth rates, death rates, and migration patterns.
  3. Population growth can be positive (increase) or negative (decline).
  4. The global population has grown significantly since the Industrial Revolution.
  5. In the 20th century, the world experienced a population explosion, particularly after World War II.
  6. The global population reached

Population distribution and density

  1. Population distribution refers to the way people are spread across the Earth's surface.
  2. Population density is the number of people per unit area, usually expressed as people per square kilometer.
  3. Population distribution is influenced by physical, economic, social, and political factors.
  4. Areas with favorable climate, fertile soil, and water availability tend to have higher population densities.
