2.4 Population Dynamics

• What does the term "population dynamics" refer to?

  Changes in population size and composition
• Births, deaths, and migration are the only factors that influence population dynamics.

  False
• The number of births in a given period is referred to as births
• The primary components influencing population dynamics are births, deaths, and migration
• Why is understanding population dynamics important?

  Resource allocation and policy development
• Match the component of population dynamics with its effect on population size:

  Births ↔️ Increases

  Deaths ↔️ Decreases

  Migration ↔️ Increases or Decreases
• The movement of people in or out of an area is called migration
• What does the Demographic Transition Model describe?

  Stages of population change
• What characterizes the Pre-Transition stage of the Demographic Transition Model?

  High birth and death rates
• What happens to birth and death rates during the Early Transition stage?

  Both decline
• What is the impact of economic development on birth rates?

  Declining birth rates
• Declining birth rates are associated with improved incomes
• Government policies can be pronatalist to encourage higher birth rates.
• What is the primary focus of population dynamics?

  Changes in population size
• Healthcare access influences death rates


  True
• The population growth rate is calculated as `(End Population - Start Population) / Start Population`.
• What is the formula for the net migration rate?

  Immigration Rate - Emigration Rate
• In the Pre-Transition stage, both birth and death rates are high

  True
• The Post-Transition stage is characterized by low birth rates and low death rates, resulting in slow population growth.
• How does economic development impact birth rates?

  Declining birth rates
• Government policies can affect healthcare access and mortality rates


  True
• What are the key influencing factors for births in population dynamics?

  Fertility rates and cultural norms
• The net migration rate is calculated as the difference between immigration and emigration.


  True
• Arrange the stages of the Demographic Transition Model in the correct order:

  1️⃣ Pre-Transition

  2️⃣ Early Transition

  3️⃣ Late Transition

  4️⃣ Post-Transition
• The Late Transition stage of the Demographic Transition Model is marked by rapid growth
• The Demographic Transition Model illustrates how the components of population dynamics drive changes in population structure
• Social and cultural norms influence both birth rates and migration patterns.


  True
• Cultural attitudes towards healthcare influence death rates


  True
• Environmental degradation can lead to increased mortality rates


  True
• Birth rates are affected by fertility rates and access to family planning.
• What does migration refer to in population dynamics?

  Movement of people
• The natural increase rate is the difference between birth rate and death rate


  True
• The Demographic Transition Model describes stages of population change based on birth rates and death rates.
• What happens to population growth during the Early Transition stage?

  Moderate
• Understanding the Demographic Transition Model is crucial for effective population planning


  True
• Social and cultural norms influence death rates through attitudes towards healthcare.
• What type of migration is driven by environmental factors?

  Climate change migration
• Pronatalist policies are designed to encourage higher birth rates
• Changes in population dynamics are driven by births, deaths, and migration.


  True
• What are the two types of checks proposed by Malthus to combat overpopulation?

  Positive and preventive
