Why is the UK's population ageing? Babies in the UK are living longer and therefore life expectancy is increasing. The UK population is still growing but only slowly. However, by 2021 19% of the UK population will be pensioners. This is due to the baby boom after World War Two. Population pyramids are used to explain this process.
Show this clip to introduce population pyramids, then show students different population pyramids and ask them to explain their shapes. Ask students to annotate images of their/ a family to explain how different members will be affected by an aging population. Consider the effect of an aging population have on pensions and healthcare and strategies to tackle the resulting problems. Will people have to work for longer?
