3.2.2.2 Population Dynamics

• Population dynamics refers to the study of changes in population size and structure over time
• Migration refers to the movement of people into (immigration) or out of (emigration) a population
• One key factor affecting birth rates in the UK is the availability of contraception
• The natural increase in a population is calculated by subtracting the death rate from the birth rate.
• Government policies can increase birth rates through incentives like child benefits or parental leave.
• Population growth, decline, or stability depends on the interaction of birth rates, death rates, and migration.

  True
• Economic recessions in the UK tend to decrease birth rates as couples delay having children.


  True
• What is the death rate defined as?

  Deaths per 1,000 people
• How do environmental factors affect death rates in the UK?

  Pollution, climate change increase death rates
• What are some common regions involved in international migration to the UK?

  Eastern Europe, India, Nigeria
• What is the formula for calculating natural population increase?

  Birth rate - Death rate
• What does population dynamics refer to?

  Changes in population size and structure
• The components of population dynamics interact to determine whether a population grows or declines over time.


  True
• Economic recessions in the UK tend to decrease birth rates as couples delay having children.


  True
• Healthier lifestyle choices, such as better diet and exercise, lead to lower death rates in the UK.


  True
• Arrange the types of migration in the UK from internal to international:

  1️⃣ Internal migration

  2️⃣ International migration
• Better job prospects and high-quality education act as pull factors attracting immigrants to the UK.


  True
• If the UK has a birth rate of 11 per 1,000 and a death rate of 9 per 1,000, what is the natural population increase?

  2 per 1,000
• Urban overcrowding in the UK leads to housing shortages and strained infrastructure
• The UK's age pyramid shows a larger elderly population, leading to increased healthcare costs and pension system pressures.

  True
• How does contraception availability affect birth rates?

  Decreases birth rates
• Population dynamics studies changes in population size and structure over time.


  True
• The factors of population dynamics interact to determine whether a population is growing, declining, or remaining stable.

  True
• Match the component of population dynamics with its measurement:

  Birth rate ↔️ Births / Total population x 1,000

  Death rate ↔️ Deaths / Total population x 1,000

  Migration ↔️ Immigration or emigration

  Natural increase ↔️ Birth rate - Death rate
• Economic recessions in the UK tend to decrease birth rates as couples delay having children.


  True
• Contraception availability decreases birth rates by allowing couples to control family size.


  True
• What is migration defined as?

  Movement into or out of a population
• What are some key factors affecting birth rates in the UK?

  Contraception, economy, policies, culture
• How can government policies affect birth rates in the UK?

  Incentives like child benefits
• Medical advancements in the UK decrease the death rate by improving disease treatment and prevention.


  True
• Higher socioeconomic status in the UK is associated with lower death rates due to better education, income, and healthcare access.


  True
• Unemployment and high costs of living are examples of push factors driving emigration from the UK.
• If the UK has a birth rate of 11 per 1,000 and a death rate of 9 per 1,000, the natural population increase is 2 per 1,000.
• The number of live births per 1,000 people per year is called the birth rate.
• What are some key factors affecting birth rates in the UK?

  Contraception, economy, policies, culture
• How can government policies affect birth rates in the UK?

  Incentives like parental leave
• What are some environmental factors that can increase death rates in the UK?

  Pollution, climate change, disasters
• What are some common regions involved in international migration to the UK?

  Eastern Europe, India, Nigeria
• Unemployment and high costs of living are examples of push factors driving emigration from the UK.
• What is natural population increase calculated as?

  Birth rate - Death rate
