The purpose of this paper is to describe the four phases of demographic transition and give examples of each in different countries.
The "Demographic Transition" is a model that describes population change over time. It is based on an interpretation begun in 1929 by the American demographer Warren Thompson, of the observed changes, or transitions, in birth and death rates in industrialized societies over the past two hundred years or so. (Geology, 2012) Demographic transition is defined as the tendency of a population to shift from high birth and death rates to low birth and death rates as a result of the epidemiologic transitions and fertility transitions. This result is a very slow growing population or sometimes no growth at all. Epidemiologic transition is simply the shift from high death rates to low depth rates due to the help of the invention of modern medicine and sanitary developments within certain countries. Fertility transition is ...view middle of the document...
Fertility transition is simply defined as the decline of birthrates from high levels to low levels in a population. This explains why this phase represents the largest decrease in births that can be linked to a number of reasons.
Phase 4 is a representation of the post-industrial stage. Populations in this phase will see very low growth rates which could lead to a zero population growth, and in extreme some cases negative net growth rates.
Some reasons for the decline in birth rates in developing countries could be supporting a family planning program, having an increased economic role in the country for women, this will get women interested in getting educated and becoming part of society as more than just a mother.
Reasons for the decline in death rates would be the invention of modern medicine. We see every day that break troughs in medicine are extending the life span of individuals.
I believe if a countries goal is to reach phase four it needs to make birth control available to all women young and old to prevent unwanted pregnancies that would indeed increase the population. The second step would be to encourage all their citizens to be highly educated and make sure they all have access to basic medical care.
We in the United States are very fortunate that we have reached and surpassed phase 4. On the food level we are very fortunate in the fact that we have hundreds of ways to grow and produce our food. We also have most of our population living in good to great housing. For those that cannot afford housing the government has laws in place to help them get viable housing. Other countires do not have this in place like Africa, where most of their population lives in tents with no clean drinking water and maybe access to one meal a day.
