Comprehensive Study Guide for the Demographic Transition Model

Stage 11: High Stationary

  • Characteristics of Birth and Death Rates: In this initial stage, both birth rates and death rates are high.

  • Population Dynamics: The resulting total population size is low.

  • Examples: There are currently no entire countries that exist within Stage 11.

Stage 22: Early Expanding

  • Characteristics of Birth and Death Rates: Birth rates remain high, while the death rate falls.

  • Population Dynamics: As a result of the falling death rate combined with high birth rates, the population grows.

  • Examples of Countries in Stage 22:   - Nigeria   - Guatemala   - Afghanistan   - Yemen

Stage 33: Late Expanding

  • Characteristics of Birth and Death Rates: Birth rates begin to gradually decrease, and death rates are low.

  • Population Dynamics: The rate of population growth slows down during this stage.

  • Examples of Countries in Stage 33:   - Mexico   - India   - South Africa

Stage 44: Low Stationary

  • Characteristics of Birth and Death Rates: This stage is characterized by both a low birth rate and a low death rate.

  • Population Dynamics: The population remains constant, a state also described as zero population growth.

  • Examples of Countries in Stage 44:   - Canada   - South Korea   - United States

Stage 55: Declining

  • Characteristics of Birth and Death Rates: Both birth rates and death rates are low.

  • Population Dynamics: The total population is decreasing; additionally, the elderly population is decreasing.

  • Examples of Countries in Stage 55:   - Japan   - Germany

Long-Term Prospects and Speculation for Stage 55 Countries

  • Speculative Nature of Future Outcomes: The long-term prospects for countries currently in Stage 55 are considered a matter of speculation.

  • Dependencies for Population Decline Effects: The specific effects of a declining population over time are likely dependent on two main variables:   - The overall size of the population.   - The specific nature of the country’s economy.

  • Key Influencing Factors: Changes in other environmental and social factors may play a critical role in determining whether and how a population in a Stage 55 country will continue its decline. These factors include:   - Technology: Shifts or advancements in technological capabilities.   - Immigration: The role and scale of people moving into the country.
