1 of 16

what are the advantages of the model

  • Its dynamic - it shows changes through time
  • It describes what has happen in the UK
  •  USA and many other western countries have also been through the same stages
  • Some countries are going through it at the moment - Newly Industrialised Countries, like South Korea
  • Explains what has happened
  • Explains why it happened in that particular sequence
2 of 16

what are the disadvantages of the model?

  • Its Eurocentric
  • Based on western Europe
  • Based on events from the past
  • Its had to have been adapted since it was used – Stage 5 was added
  • Not relevant to countries that aren’t industrialized
  • Some LEDCs have imported medicine/sanitation techniques from MEDCs
  • Does not give a timeline for how long it will take – 260 years for UK but South Korea seems to be rushing through in decades
  • It doesn’t take migration rates into account
  • Many factors affect death rate such as; famine, natural disasters, war.
  • It doesn’t show Governments/Non-Government intervention
  • Countries census data could be inaccurate
  • DTM assumes all countries will go through stages in a certain order. Many countries in Africa seem to be in Stage 5 due to the HIV and Aids epidemic.
  • It cannot predict what will happen in the future E.g. Natural disasters
