Demography and the Family

Demography is the study of population change. In this topic, students examine the trends in birth rates, death rates, and migration that are reshaping the UK. They explore the reasons for the 'ageing population' and its impact on the family (such as the rise of the 'sandwich generation') and the wider economy. They also look at how migration has contributed to the diversity of family structures in Britain.

Inquiry Circle: The Ageing Population Map

In small groups, students are given data on the UK's ageing population. They must create a 'consequence map' showing how this trend affects different areas of life: the family (grandparenting), the economy (pensions), and the state (healthcare).

Simulation Game30 min · Whole Class

Simulation Game: The Dependency Ratio

Using a physical representation (like students standing in groups), model the 'dependency ratio' in 1950 versus 2050. Students must discuss the challenges of having a smaller 'working' group supporting a larger 'retired' group.

Think-Pair-Share: Why are birth rates falling?

Students list three reasons why women are having fewer children (e.g., career focus, contraception, cost). They share with a partner and rank them in order of importance for a woman in the 21st century.

A few notes on teaching this unit


Watch Out for These Misconceptions

  • An ageing population is purely a 'burden' on society.

    While it poses challenges, older people also provide 'free' childcare (the 'silver economy') and contribute through volunteering. A 'debit/credit' activity can help students see the nuanced sociological view of the elderly as both a challenge and a resource.

  • Migration is the only reason the UK population is growing.

    Natural increase (births minus deaths) and increasing life expectancy also play major roles. Using a 'population pyramid' analysis helps students see that migration is just one piece of a much larger demographic puzzle.
