Impacts – Understand the social, economic, environmental and political consequences for different places and populations.
Stakeholders – Identify the groups involved and understand how their interests and perspectives may differ.
Responses and management – Know how governments, organizations, communities and other stakeholders responded.
Successes and limitations – Be prepared to evaluate how successful different responses or management strategies have been.
Evidence – Learn a few useful statistics, dates, locations or other specific details that make your example convincing.
Geography course connections – Understand which concepts and syllabus topics the example can support.
Core Theme: Population Distribution – Changing Population
Japan – Ageing Population
Japan is one of the most useful examples for studying an ageing population and changing population structure. Low fertility combined with high life expectancy has increased the proportion of elderly people within the population. This creates challenges involving the workforce, healthcare, pensions and the provision of services. Government responses to demographic change can also be evaluated. This case study can be connected to:
Ageing populations
Population structure
Fertility rates
Dependency ratios
Labour shortages
Population policies
Economic impacts of demographic change
China – Population Policy
China's population policies provide a useful example of government attempts to influence demographic change.

How to Learn IB Geography Case Studies
You do not need to memorize enormous amounts of information about every case study. Instead, make sure you can explain where the example occurred, what happened, why it happened, who was affected and how governments or other stakeholders responded. Adding a few precise statistics, dates or named policies can make your evidence much stronger. Try to avoid memorizing case studies as isolated stories. Instead, think about the geographical concepts each example demonstrates. For instance, Bangladesh can help you discuss climate vulnerability, flooding, adaptation, inequality and population displacement, while Singapore can support arguments about water security, urban sustainability, technology and resource management.
