IB Geography: Population Distribution Practice
IB Geography — Population Distribution Practice
16 MCQ practice problems covering core IB Geography population distribution content.
Practice Questions
Intuition
For population questions, always consider both the numerical data and the human stories behind it. Population pyramids reveal not just current structure but future implications — a wide base today means a youth bulge in 15 years, which could be a demographic dividend or a source of instability. When discussing migration, always consider both push and pull factors and the impacts on both origin and destination. The IB rewards evaluative answers that consider multiple perspectives and use specific country examples.
Why it matters: Population distribution affects everything from economic growth to resource demand to political stability. Understanding demographic trends helps governments plan for healthcare, education, pensions, and infrastructure. Migration patterns shape cultural diversity, labour markets, and international relations. These practice questions test your ability to apply population knowledge to exam scenarios.
Worked Example
Question: Using the DTM, explain why Nigeria’s population is growing rapidly while Japan’s population is declining.
Answer Structure: Nigeria is in Stage 2/3 of the DTM — death rates have fallen due to healthcare improvements, but birth rates remain high due to limited contraception access, cultural preferences for large families, and high infant mortality. This creates rapid growth. Japan is in Stage 5 — low birth rates (urbanisation, high cost of living, women’s education and career opportunities) combined with high life expectancy (advanced healthcare) means deaths exceed births. Evaluate: the DTM is useful but oversimplifies — it assumes all countries follow the same path and doesn’t account for migration or policy interventions.
Common Mistakes
- Confusing crude birth rate (per 1000 people per year) with total fertility rate (average children per woman). They measure different things and are not interchangeable. CBR is affected by population structure; TFR is more directly comparable across countries.
- Assuming all population growth is natural increase. Migration can significantly affect population change, especially at the national level for countries with large immigrant or emigrant populations. Net migration rate must be considered.
- Forgetting that population policies have unintended consequences. China’s one-child policy reduced birth rates but created a gender imbalance (sex-selective abortion) and an ageing population. India’s sterilisation programme damaged trust in government healthcare.
- Confusing the dependency ratio with the demographic dividend. The dependency ratio measures the burden on the working population; the demographic dividend is the economic growth potential when the working-age population is large relative to dependents.
Cross-References
- Climate Change: Climate change drives displacement and migration, and population growth increases emissions and vulnerability.
- Economic Development: Demographic transition is closely linked to development — economic growth drives falling birth rates.
- Freshwater Issues: Population growth increases water demand, and water scarcity can drive migration.
- Urban Environments: Urbanisation is closely linked to demographic transition — urban areas have lower birth rates.
