Understanding Population Growth Essay

1222 words - 5 pages

“The study of human characteristics of human populations” is known as demography which helps depict the progress of nations at many levels (Know, Marston, Imort and Nash, 2011, p. 99). Also it displays information that can relate to the current problems that the nations are facing. The advancement of populations is measured using the demographic transition theory which consists of four main phases, with unique characteristics that countries are grouped within. Studies conducted on these nations are significant as it helps us gain an understanding of the current position the country is in, and how it can develop into an industrialized nation.
According to the demographic transition theory, countries are grouped within four phases ranging from pre-industrial to an industrialized based economic system. The demographic transition theory is a, “model of population change when high birth and death rates are replaced by low birth and death rates” (Knox, et. al., 2011, p 114). To begin with, the first phase is characterized by a pre-industrialized economic based system, with high fertility rates and high mortality rates. From the data given to us for the 1950’s, it appears as if we could group Brazil, China, India and Kenya into the first category, as each of these countries possessed these characteristics. Going forward, the second phase is known as the transition stage where the death rates drop rapidly due to improvements in food supply and hygiene which increases the average life span of the citizens, as well reduces the spreading of diseases. However, in this phase the fertility rates still remain high, and this results in rapid growth of the population. In 2010, Kenya and India slowly made their way into this stage, as their death rates have dropped significantly yet their rates continue to increase. This period leads on to the third stage which is also known as a transition phase which is a huge leap forward in terms of progress of a nation. Knowledge about sex, increases in wages, and urbanization are the major traits of this stage. As of 2010 China and Brazil are in this particular stage, and are rapidly growing with the hope of one day developing into a fully industrialized society. As for Canada’s placement within this model, it is unclear as to what they are grouped in as there is no general consensus regarding this matter. What is known is that they are between the third and fourth stage of this model. Lastly we have the industrialized phase that only a handful of countries are grouped within. This final stage possesses both a low birth rate and death rate which can often lead to a shrinking population. For the countries we collected data for, none of them are considered to be at this stage, however, they continue to grow, and are coming closer and closer to reaching this ideal phase of this model.
From the data collected it is evident that there is a vast diversity in the setup of each individual country. ...
