Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What did Malthus predict about population and food supply?

    Model answer

    He argued that population multiplies far faster than food production can grow, so growth is checked by famine, disease and war unless people restrain themselves.

  2. 2

    Why has the Malthusian prediction not been borne out?

    Model answer

    Agricultural technology, new crop varieties, fertiliser and trade raised food output faster than population, and fertility fell as countries developed.

  3. 3

    What did Boserup argue against Malthus?

    Model answer

    She argued that population pressure is a spur to innovation, because farmers intensify cultivation and adopt new methods when there are more mouths to feed.

  4. 4

    Outline the demographic transition model.

    Model answer

    It describes a move from high birth and death rates, through a stage where deaths fall first and population grows rapidly, to low birth and death rates and a stable population.

  5. 5

    Why does population continue growing after fertility falls?

    Model answer

    A previously youthful population still contains a large number of people entering their childbearing years, so births stay high for a generation.

  6. 6

    Name three reasons fertility falls as a country develops.

    Model answer

    Child mortality falls so fewer births are needed, women gain education and paid work, and contraception becomes available and acceptable.
