Assess the validity of the DTM for understanding global population The DTM shows us typical population trends in stages. Although it gives an idea of the population ages, its validity for assessing global population could be argued, to some extent, due to factors affecting it, such as disease. The fact that the DTM has no time scale can be positive, in so much as different countries go through the stages at different times. e.g. countries in Africa go through the stages very slowly and countries in Europe such as Norway went through them very quickly. However the downside of the DTM having no time scale is that accurate predictions cannot be made such as what the population is going to be at a certain time. Another validity problem with the DTM is “Cultural Variations”. The DTM is based on Christian industrialized western patterns. This is a problem in places like India where there is culture of people having very large families, increasing the global population. The DTM does not take migration into account; migration can strongly effect country’s DTM. You would think that someone moving from one country to another would not affect global population; but it can. People generally move from a poor country to a rich country rather that from a rich country to a poor country. For example someone who lived in Niger might have four children and three of them might die but if they moved to the UK they will have the privilege of better health care, so are likely to have more children where the likeliness of them dying is dramatically reduced. The DTM does not take account of the factors such as famine, natural disasters and war…although it is affected by all of them. The two former factors are likely to reduce the working population; and war is most likely to reduce the working population. DTM assumes all countries will go through the stages in
