Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is meant by demographic change?

    Model answer

    Demographic change is a change in the size or the structure of a population. Age distribution, birth rate, death rate and migration are the main components.

  2. 2

    What is meant by an ageing population?

    Model answer

    An ageing population is one in which the average age is rising and older people form a growing share. Longer life expectancy and a falling birth rate together produce the effect.

  3. 3

    Give two causes of an ageing population in the United Kingdom.

    Model answer

    Rising life expectancy, produced by better healthcare and diet, is one cause. A long-term fall in the birth rate is the second.

  4. 4

    How does an ageing population create opportunities for business?

    Model answer

    Demand grows for healthcare, retirement housing, leisure travel and financial products for retirement. Firms that redesign products for older customers gain a growing market.

  5. 5

    How does an ageing population create problems for business?

    Model answer

    The pool of younger workers shrinks, so recruitment becomes harder and wages are bid up. Pension and healthcare costs also rise for employers and for government.

  6. 6

    What is the dependency ratio?

    Model answer

    The dependency ratio compares the number of people outside the working-age group with the number inside it. A rising ratio means fewer workers support each dependent person.
