Core 1 • Section 3
Challenges & Opportunities
How population structures create challenges and opportunities—and how governments respond through policy, equality, protection and investment.
Population possibilities and power over the decision-making process
Global population challenges: ageing societies
Global and regional trends in family size, sex ratios and ageing.
An ageing population is a shift in structure, not simply “more old people”. Falling fertility and rising life expectancy increase the older share while the working-age share may shrink.
Longer lives
Labour shortages
Automation
Japan: a super-ageing case study
Causes, consequences and possible responses to population ageing.
Very low fertility, long life expectancy and population decline reshape Japan’s workforce and dependency. Build a cause–consequence–response chain.
Case-study frame
- What created Japan’s age structure?
- How does ageing affect labour and dependency?
- Which responses alter fertility, labour supply or productivity?
- Which response is most sustainable?
Managing population change: China
Anti-natalist policy and its intended and unintended consequences.
Evaluate rather than merely describe: Did the One Child Policy change fertility? What were its unintended consequences? How have later policy changes responded?
Pro-natalist policy: Singapore
Government attempts to influence family size below replacement level.
Singapore’s policy changed direction from limiting growth to encouraging births. Compare financial incentives with the deeper reasons people decide whether to have children.
Evaluate the policy
- Cost: how expensive are incentives and services?
- Reach: who benefits?
- Behaviour: does it actually change decisions?
- Time: how long before the structure changes?
Gender equality: Rwanda
How power and opportunity influence education, work, health and reproductive decisions.
Rwanda provides a case study of how policy can change political representation and opportunity—while prompting the question of which inequalities remain.
Human trafficking & population vulnerability
Anti-trafficking policies and unequal power shaping movement and vulnerability.
Trafficking differs from migration and smuggling through exploitation and control. Poverty, insecure status, discrimination and weak protection increase vulnerability.
Interactive enquiry — Trapped at Sea
Work through the graphic journey and track how recruitment, debt, isolation and unequal power increase vulnerability. Afterwards, identify where prevention, protection, prosecution and partnership could interrupt the trafficking process.
The demographic dividend
How population may become a resource when contemplating possible futures.
A demographic dividend is a potential benefit, not an automatic reward. Falling fertility can increase the working-age share, but opportunity becomes a dividend only with health, education, productive employment and an enabling economy.
The key evaluation
- What age-structure change creates the opportunity?
- Which investments create productive human capital?
- What happens if jobs do not grow fast enough?
- How might gender equality increase the dividend?
