The Demographic Transition Model

Q: A summary of  the Demographic Transition Model and show its disadvantages and Advantages

The demographic transition model shows the relationship  between Births,Deaths and population increase or decrease over a period of time in a single diagram.The graph shows different situations  in through out the world due to differences in technological and medical advancement.

        

        The first stage of the model is typical of least economically developed countries,charecterised by high birth and death rates resulting in minimal population growth.High death rates are due to famine which is widespread in Africa and most Middle East countries.War contributes to the hunger and starvation the population as people are flee the cities and farms to hide in the mountains where food supplies cannot reach them and there is poor hygiene facilities,no clean water and limited medical infrastructure.The diet is minimal and thus an outbreak of malnutrition  wipes out infants at young age and the poor living conditions would result in diseases such as cholera and kwashiorkor which take their toll on the population .Deaths are high among children and most would die at birth.Poor contraception methods result in many though fatal births  due to  sexually transmitted diseases such as Aids, Herpes, Gonorrhea etc

Overall rating: 3 out of 5 stars. The report starts well with clear descriptions and explanations of each stage and the use of some examples. However, it falls down on the critique/evaluation that follows - which is actually the most important part of the report. It is not evident that the student fully understands the more technical points they are making as they are not integrated into the discussion or explained. Also, it seems the student is a little confused on the concept of a model as opposed to a graph of data for different countries. Some useful and appropriate points are made in support and against the model but overall it seems they can describe it, but may not fully understand its purpose and features fully.
