Classical And Modern Demographic Transition

2,000 years ago the world, in terms of population, was only the size of the United States of America, 300 million people. Today, the world’s population is at seven billion and counting. If the population rose at a steady rate from year 0, we would’ve reached 1 billion people by about 210 A.D. This, however, was not the case. We reached 1 billion people in 1800 A.D, which means that there had to be very odd growth periods for the population as a whole REWORD ME. From 0 to 1000 A.D. the population only rose about 10 million people, “and well into the second millennium, [the population] grew less than 0.1 percent each year” [1]. However, from the year 1800, with 1 billion people worldwide, to 1930, the world gained another billion people. We then reached three billion people in 1960, five billion in 1987, and 7 billion in 2013. One can clearly see that once we entered the 19th century, the world’s population started growing like a 14 year old boy going through puberty; rapidly, and without any warning. One thing that can explain this growth is called the Demographic Transition.The Demographic Transition is a theory that explains the growth.

The human population rate has changed throughout the ages. By looking at the table we were given the human population has increased heaps from 2000 years ago. If we look at our ancestors they lived with a small existence but this has changed as we have developed and there is more agriculture in this world. Population grew very slowly in the 1000 A.D. also decreased after the Black Death causing large numbers of people wiped out. Then in the 1800 A.D. the industrial revolution came, soon living standards were raised and there was food shortage with the population. In 1927 medicine was introduced this meant that there was increased life expectancy, so the human population grew more. There was more advantages from agriculture, medicine and sanitation

The demographic transition is a three-stage model of population growth in Europe. In the first stage there is a stable population because birth and death rates are both high. The second stage happens as mortality rates begin to slowly decline, but birth rates stay high. When this stage happens, there is fast population growth. During the third stage, the population is more stable as both birth and death rates are low and are more or less balanced. In more recent years, a fourth stage as been brought on by Anti-Malthusians. During this stage, population shrinkage occurs because the deaths begin to outnumber the births. Europe provides a great example to the theory of demographic transition. After speedy population growth of stage two, Europe settled at stage three with a stable population. It is currently in stage four with a shrinking population. In most European nations there are lesser births than deaths which could ultimately create other social problems.

Chapter 16 also brings up the issue of population increase. With the demographic transition theory, we learn about the trends of each societies as they go through modernization. In the book as well as the article, we learn about IPAT. Formula

For the past two decades a shifting pattern of diseases and health care service has been observed globally as population increase. Epidemiological transition also known as demographic transition, is a model that is used to explain how population growth rates increase and decrease with respect to time and different factors that account into it such as infectious disease, chronic disease and industrialization. “Conceptually, the theory of epidemiologic transition focuses on the complex change in patterns of health and disease and on the interactions between these patterns and their demographic, economic and sociologic determinants and consequences” (Omran, 2005). This model describes the changing patterns of population distributions in four stages: Age of pestile and famine, age of declining pandemic, age of degenerative and man-made diseases, and postindustrial age.

Demographic transition is the process by which a nation/country moves from high birth rate and high death rates to low birth and low death rates as the growth population in the interim (Weeks, 2005). Some of the nations that have gone through this transitions are; Canada, Germany, United States and England. The demographic transition to an industrialized society is harmful to the environment. Industrialized countries also have the largest ecological and carbon footprint comparative to developing/non-industrialized nations. Nevertheless, demographic transitions have some notable advantages. Countries that have gone through demographic transitions have low birth and death rates. Citizens in

Dictator Pol Pot held goals of attaining independence in Cambodia. He was also determined in making both social and economic reforms in Cambodia. However, he did not achieve his goals. This was due to his fall in the year 1978. The effects of his poor leadership were the major causes of his fall. Based on the behaviorism approach, a leader should portray good characters that are beneficial to his people. Good behavior is rewarded while bad behavior is punished (Chandler, 1999). Therefore, his behavioral consequences were punished because he failed in his leadership. Due to his harsh and brutal leadership, revolts were made against him. As a result, he lost power before achieving his goals. Therefore, good leadership traits and behavior would lead pol to achieving

The demographic transition has been closely accompanied by an epidemiological transition in the area of health, that is, a change in the profile of morbidity and mortality by cause, and the distribution of deaths by age. This transition is apparent in the percentage reduction in deaths caused by transmissible (respiratory, infectious and parasite–borne) diseases and in those in the perinatal period, giving rise to a relative predominance of deaths caused by chronic and degenerative diseases (of the circulatory apparatus and malignant tumors), as well as external causes (caused by violence, accidents and injuries). This reflects both the greater drop in mortality for the first group of causes, which mainly occur in children, as well as by the

These progressions lead to the control of sicknesses, the creation of more nourishment, better employments, and enhanced restorative consideration and sanitation. As the passing rates diminish, the conception rates stay high on the grounds that individuals are still usual to creating more youngsters, and amid this stage they have more nourishment and assets to help bigger families. As an issue of the declining passing rates and high conception rates, the human populace will increment at a fast

Afghanistan is in Stage 2 due to the rise in population caused by a decline in the Crude Death Rate (14) while the Crude Birth Rate (38) remains high. CDR declines as new health care systems arrive, and CBR still remains high because most families are still subsistence farmers (and deeply involved in cultural tradition). The population pyramid is expansive and has straight sides. The pyramid shows a slightly longer life expectancy and more people living into middle age. The change in the age structure of the population leads us to conclude that Afghanistan is in Stage 2 of the demographic transition.

Demographic change can impact on a slower reduction in TB incidence. Barcelona TB Control Program (PPCTB), Community health workers (CHW), and Public health nursing team (PHNT) also helped improve action procedures for immigrants including monitoring cases and their contact in accordance with international

One characteristic that is similar of demographic and epidemiological transitions is that they both focus on mortality within a population. Both examine mortality changes within a population, and can even measure mortality within the same population, (yet demographic does this on a overall level and epidemiological in a cause-specific manner). It is clear that both transitions measure mortality at the population level.

Maggie Nguyen Mr. Trivette Free Response Question #2 08 September 2015 a.) The five stages in the Demographic Transitional Model are the Low Growth Stage, Increasing Growth Stage, Moderate Growth Stage, Stationary Stage, and Population Decline Stage. b.) The Low Growth Stage is when an area has a high birth rate and a high death rate, which ultimately does not have a long-term effect on a population.

Unlike society a few decades before, the life expectancy has increased and now America is seeing an exponential growth to the elderly population. There are many factors that could be the cause of this. Looking at the demographic transition theory in conjunction with the Malthusian theory brought valuable insight for me. The demographic theory says there are four stages to population growth that are predictable. Those who are in their late 80’s and above were capable of seeing all four of these stages in America. As they aged and the stages for population advanced so did technology. Malthusian theory claims that there are three factors that prevents the human population exceed its carrying capacity, which are food, disease, and war. Those who lived through the four stages of America were lucky enough to see technology advance to prevent those factors in being lethal to our population. It became possible for adults to live on to see their grandchildren and eventually their great grandchildren.

Demography is the study of the components of population variation and change. Death rate and birth rate are two determinants of population change. Theory of Demographic Transition is comparatively recent theory that has been accepted by several scholars throughout the world. This theory embraces the observation that all countries in the world go through different stages in the growth of population. A nation's economy and level of development is directly related to that nation's birth and death rates. Population history can be divided into different stages. Some of the scholars have divided it into three and some scholars have divided it into five stages. These stages or classifications demonstrate a
