Summary
Population structure is influenced by natural increase and net migration, shaping the age and gender composition of populations. Youthful populations arise from high fertility and lower life expectancy, while ageing populations result from low fertility and high life expectancy. Population policies aim to manage these demographic challenges but face cultural and economic barriers.
Exam Tips
Key Definitions to Remember
- Natural Increase: The difference between birth rate and death rate.
- Net Migration: The balance between immigration and emigration.
- Youthful Population: A population with a high proportion of individuals under 15 years old.
- Ageing Population: A population with a high proportion of individuals aged 65 and over.
Common Confusions
- Confusing natural increase with net migration as the sole factor affecting population growth.
- Assuming all countries with high birth rates have youthful populations without considering death rates.
Typical Exam Questions
- How does net migration affect the population structure of a country? Positive net migration increases the working-age population, while negative net migration can accelerate ageing.
- What are the social and economic impacts of a youthful population? High demand for education and healthcare, potential for future workforce growth, but risk of unemployment.
- Evaluate the effectiveness of population policies in an ageing population. Policies may include pro-natalist incentives and healthcare reforms, but effectiveness is limited by cultural and economic factors.
What Examiners Usually Test
- Understanding of how birth and death rates influence population structure.
- Ability to analyze the impacts of youthful and ageing populations.
- Evaluation of population policies in specific country contexts.
