Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    Why can an average income figure give a misleading picture of how people in a country live?

    Model answer

    It is an average, so it hides the gap between the very rich and the very poor and the gap between regions of the same country.

  2. 2

    Give two reasons why data on a country's development may be unreliable.

    Model answer

    The figures may be years out of date, and work done informally or for no pay is often left out of the count altogether.

  3. 3

    Why is a combined index often preferred to a single economic figure?

    Model answer

    Because it brings together income with health and education, so it reflects how people actually live rather than only how much the country earns.

  4. 4

    In Stage 1 of the Demographic Transition Model, what are birth and death rates doing, and what happens to population?

    Model answer

    Both are high and swing up and down, so the population stays small and grows very slowly.

  5. 5

    Why does population grow fastest in Stage 2 of the Demographic Transition Model?

    Model answer

    Death rates fall steeply as food supply, clean water and medicine improve, while birth rates stay high.

  6. 6

    Why do birth rates fall as a country moves through Stage 3 and into Stage 4 of the Demographic Transition Model?

    Model answer

    More women are educated and go out to work, contraception becomes available, and fewer children die, so families choose to have fewer.
