Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is meant by demography?

    Model answer

    Demography is the study of the size, structure and distribution of a population and of how it changes through births, deaths and migration.

  2. 2

    What is an ageing population?

    Model answer

    An ageing population is one in which the proportion of older people is rising, caused by people living longer and by fewer children being born, so the average age of the population increases.

  3. 3

    What causes people to live longer?

    Model answer

    Life expectancy has risen through better nutrition and housing, clean water and sanitation, immunisation, advances in medicine and surgery, safer workplaces and falling rates of smoking.

  4. 4

    How does an ageing population affect the demand for services?

    Model answer

    More people live with long-term conditions and with several at once, so demand rises for general practice, hospital care, domiciliary care, residential and nursing home places, and for support to carers, at the same time as the working-age population funding them shrinks in proportion.

  5. 5

    What is the dependency ratio?

    Model answer

    The dependency ratio compares the number of people not of working age — children and older people — with the number of working age, and a rising ratio means fewer taxpayers supporting more people who need services.

  6. 6

    How does a falling birth rate affect services?

    Model answer

    Fewer children reduce demand for maternity, early years and school places over time, but they also reduce the future working population, which is what makes an ageing population harder to fund.
