3.1 Population Dynamics

• Population Dynamics refers to how the size and composition of a population change over time.
• Migration rate is influenced by economic opportunities, political stability, and environmental conditions.
• Match the population dynamics component with its influence:

  Birth Rate ↔️ Fertility rates

  Death Rate ↔️ Healthcare quality

  Migration Rate ↔️ Economic opportunities
• Migration is driven by economic opportunities, political stability, and environmental factors.

  True
• The old-age dependency ratio measures the proportion of the population over 65 years old.
• Match the type of migration with its description:

  Internal Migration ↔️ Movement within the UK

  International Immigration ↔️ Movement into the UK

  International Emigration ↔️ Movement out of the UK
• Population dynamics refer to changes in the size and composition of a population over time.
• Age structure is influenced by birth and death rates and life expectancy.


  True
• Order the factors affecting UK population growth from most to least direct influence:

  1️⃣ Birth Rate

  2️⃣ Death Rate

  3️⃣ Migration Rate
• What does the old-age dependency ratio measure?

  Proportion over 65 years
• International emigration from the UK is influenced by economic prospects, political climate, and family reasons.


  True
• Improvements in healthcare and urbanization contribute to the transition between stages in the Demographic Transition Model.


  True
• What is the definition of death rate in population dynamics?

  Deaths per 1,000 people
• What are the key influences on birth rate in the UK?

  Fertility rates, healthcare access, cultural norms
• Birth rate is influenced by fertility rates, access to healthcare, and cultural norms.
• Match the age structure component with its implication:

  Youth Dependency Ratio ↔️ Demand for education

  Old-Age Dependency Ratio ↔️ Demand for pensions

  Working-Age Population ↔️ Supports economic growth
• Why is understanding a population's age structure important for governments?

  Resource allocation and planning
• Migration patterns are solely influenced by economic factors.

  False
• Match the key component of population dynamics with its influencing factors:

  Birth Rate ↔️ Fertility rates and healthcare

  Death Rate ↔️ Healthcare and nutrition

  Migration Rate ↔️ Economic opportunities and stability
• The birth rate is influenced by fertility rates, access to healthcare, and cultural norms.
• Birth rate is the number of births per 1,000 people per year.


  True
• The birth rate, death rate, and migration rate interact to determine the overall population growth in the UK.


  True
• What is the definition of birth rate in the context of UK population growth?

  Births per 1,000 people
• What does age structure refer to in population dynamics?

  Distribution across age groups
• The working-age population includes individuals aged 15-64.


  True
• What are the primary reasons for international emigration from the UK?

  Economic prospects and climate
• What does the birth rate measure in population dynamics?

  Births per 1,000 people
• What are the three main factors affecting UK population growth?

  Birth rate, death rate, migration
• What are the economic and social implications of changes in age structure?

  Dependency ratios and resource demand
• The working-age population supports economic productivity and growth, but may face higher dependency burdens.
• Stages of the Demographic Transition Model

  1️⃣ Pre-Transition

  2️⃣ Early Transition

  3️⃣ Late Transition

  4️⃣ Post-Transition
• In the Post-Transition stage of the Demographic Transition Model, both birth and death rates are low.
• The migration rate in the UK is affected by economic opportunities, political stability, and environmental conditions.


  True
• Changes in the working-age population can affect economic productivity and growth.


  True
• A high youth dependency ratio indicates increased demand for education and healthcare.

  True
• Internal migration in the UK often involves movement from rural to urban areas.
• In the Early Transition stage of the Demographic Transition Model, birth rates remain high while death rates decline.
• Singapore's "Baby Bonus" scheme is an example of a pronatalist policy.

  True
• Rank the dependency ratios based on their focus:

  1️⃣ Youth Dependency Ratio

  2️⃣ Old-Age Dependency Ratio

  3️⃣ Working-Age Population
• Birth rates are influenced by fertility rates, access to healthcare, and cultural norms.
