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.
