Geography - Essay Example ch has focused on so-called transitions or changes in the population’s death rates and birth rates, as they pertain to populations in the industrialized world, stretching back two centuries. The model has four stages: stage 1, known as the pre-modern stage; stage 2, or the urbanizing/industrializing stage; stage 3, or the mature industrial stage; and stage 4, or the post-industrial stage. The early stages are characterized by high CBR and high CDR figures, at around 35-40 for every thousand. At stage four, or the post-industrial stage, the population is at its highest, even as CBR and CDR figures are at their lowest, at around 10 for every thousand people. In the model, the CBR and CDR figures trend downwards slowly from stage 1 to stage 2, but the downwards trend accelerates at stage 3, until the figures plateu at stage 4, at the levels described above, around 10 for every 1,000 population. The stages of the model, and the CDR, CBR, and population figures for every stage, are identified and plotted in this graph by way of illustration (Montgomery; Lee 167-190; Galor 1-10): In the plot above, the large population at stage 4 and the low CBR and CDR figures there are graphically illustrated. In the first stage, the birth and death rates are similar, with CBR being only fractionally larger than CDR, so that the population was almost static, and population doubling was measured in thousands of years. Stage One is characterized by high levels of infant mortality, from poor hygiene that resulted in many diseases such as diarrhea and cholera. With the advent of industrialization and urbanization. Medicine was also archaic at that time, with knowledge on disease management and prevention being basic or unavailable altogether, and the threat of hunger from famines eventually coming to pass. The high death rates countered the effect of high birth rates, or CBR, at this stage (Montgomery; Lee 167-190; Galor 1-10). In the industrialization and urbanization stage, or stage
